Over the past 100 days, Grayscale has bought every third bitcoin
Over the past 100 days, Grayscale has bought every third bitcoin The Grayscale Investments cryptocurrency investment fund acquired every third bitcoin mined in the last 100 days. And in April, the fund bought 50% of all ETH mined. At the same time, despite the financial crisis and the fall of the cryptocurrency market in March, shares of Grayscale crypto funds in the first quarter of 2020 attracted record investments, which indicates a growing interest of institutional investors in the crypto industry. Why does the company need so many coins, what is its current position regarding the crypto market and what role does it play on it?
Aggressive Grayscale crypto purchases have recently been spotted with respect to ether. So, by April 24, the company had bought about 756 539 ETNs (accurate data are not publicly available) for its Ethereum Trust fund. This is about 48.4% of all 1.5 million coins mined since the beginning of this year. As a result, the company already owns 1% of all coins in circulation and only increases the pace of purchases. The first user to notice this was Reddit under the nickname u/nootropicat. According to the latest quarterly report by Grayscale, the flow of investments in ETN reached a record level for the first three months of 2020 — $110 million. This is a very sharp increase, given that total investments in ETN for the previous two years amounted to $95.8 million. The total demand for the Ethereum fund grew over the quarter is almost 2.5 times compared with the fourth quarter of 2019. From the beginning of the year until the end of April, the company issued 5.23 million shares of the fund at 0.09427052 ETN apiece. At the same time, shares are traded with a premium of 420% relative to the current price of the coin — $92 against $17.70. That is, investors are willing to pay extra pretty much not to deal with cryptocurrency on their own. Most likely, the increase in the rate of purchase of the coin is associated with the upcoming upgrade of the network to the state of Ethereum 2.0. It can take place at the end of July, but, most likely, it will happen not earlier than the end of the year. After the upgrade, the network will become more scalable and there will be the possibility of staking — validators will be able to receive passive income for providing their funds to confirm the blocks. The crypto market, by the way, is also preparing for the transition of the ecosystem to a new stage. ETH has grown 55% since the crash in March, from $110 to $202 on the day of publication. At the end of April, CoinDesk drew attention to the increase in the number of long positions in ETH futures — this indicates expectations for further growth of the coin.
Last quarter — the most successful in the history of the company
In May, Grayscale released a report on the results of the first quarter of this year. “Despite the decline in risky assets this quarter, Grayscale’s assets continue to approach record highs, as does our share of the digital asset market,” the document says. And this despite the coronavirus pandemic, the global recession and the traditional cryptocurrency market volatility. A record $503.7 million investment was raised in the first quarter. This is almost twice the previous quarterly maximum of $254 million in the third quarter of last year and accounts for 83% of the total capital of $1.07 billion raised for the entire 2019. New investors accounted for $160 million of raised funds. The main products of Grayscale Bitcoin Trust and Grayscale Ethereum Trust raised $388.9 million and $110 million, respectively. It is noteworthy that the company reduced the premium on stocks of funds relative to the price of assets. 88% of investments came from institutional investors, among which hedge funds prevail; 5% — from accredited individuals, 4% — from pension accounts (yes, pension funds are extremely conservative in nature, but also invest in bitcoin against the background of a decrease in the profitability of other assets); 3% came from family offices, and 38% of customers invested in several products at once. It is noteworthy that two years ago the share of institutional investors was about 50% — it is obvious that they no longer consider bitcoin as something criminal. “Many of our investors see digital assets as medium and long-term investment opportunities and the main component of their investment portfolios. Quarterly inflows doubled to $ 503.7 million, demonstrating that demand is reaching new peak levels even in conditions of “risk reduction”, the document says. Today, more than 46.5% of the inflow of funds was attracted from multi-strategic investors. Crypto investors accounted for only 11.2% of the inflow, according to the report. Grayscale currently operates ten cryptocurrency investment products targeted at institutional investors. They cover PTS, ETN, ETS, BCH, ZEC, XRP, LTC, ZEN, XLM. The value of the assets under his management is more than $3.8 billion. GBTC is the most demanded product, most investors invest in it and it takes about 1.7% of the total volume of circulating bitcoins. Aggregate quarterly flow of funds to different Grayscale products. Pay attention to the growing share of investors diversifying portfolios with products tied to altcoins. Since January of this year, the Grayscale Bitcoin Trust has been registered with the US Securities and Exchange Commission (SEC). According to it, the company provides quarterly and annual reports in the form of 10-K. The status makes it possible to sell shares of a trust in the secondary market after 6 months, rather than 12, as before, and also increases the confidence of conservative investors. Other products comply with OTCQX reporting standards in the OTC market and are approved by the US Financial Services Regulatory Authority (FINRA) for public offering. Amount of assets managed by Grayscale as of May 20, 2020. It is noteworthy that the news about the success of Grayscale comes amid news of how panicky investors in traditional assets are fleeing from market turmoil. So, the largest fund managers — BlackRock, Vanguard and State Street Global Advisors — lost several trillion in capitalization of their assets, and BlackRock in the first quarter for the first time in five years saw a net outflow of funds from its long-term investment products.
Bitcoin is the best asset for hedging portfolios in crisis
At the end of April, Grayscale also released a separate report on the analysis of the impact of regulators during a pandemic and the crisis caused by it and how it affected the bitcoin and cryptocurrency market as a whole. The document said fiat currencies are at risk of devaluation as central banks print more and more money. Even the US dollar, which is the world’s reserve currency, risks being devalued if the US Federal Reserve continues to print the currency in trillions. A decrease in interest rates to zero and negative values deprives government bonds of the status of “safe haven” during the crisis. Therefore, investors are trying to diversify their portfolios with alternative instruments. Cryptocurrencies are the best choice for this, according to the authors of the report. The text emphasizes the historical significance of gold as a global standard, but it is noted that in the modern digital world it is becoming increasingly burdensome for investors — it has complex logistics. Bitcoin seems resistant to the problems that other assets face. Therefore, in times of economic uncertainty, the first cryptocurrency is one of the best assets that investors can use to hedge their portfolios. The coin performs better than any other asset, including fiat currencies, government bonds, and traditional commodities like gold. The authors of the report emphasize that Bitcoin has already begun to show signs of becoming a protective asset. At the same time, the company believes that bitcoin is an excellent asset not only in times of crisis. So, in December 2019, Managing Director of Grayscale Investments Michael Sonnenshine said that the company expects an influx of investments in bitcoin after the transfer of $68 trillion of savings between generations in the next 25 years. Today, this capital is invested in traditional assets, but a significant part of these wealth millennials will invest in cryptocurrencies. Already, according to him, investments in GBTC are among the five most popular among young people, ahead of, for example, investments in Microsoft and Netflix.
The unprecedented financial measures taken by the US Federal Reserve, as well as the worsening recession, are forcing even the most conservative investors to rethink their current strategies and portfolio composition. Many of them are increasingly beginning to appreciate the fixed emission and non-correlation of Bitcoin — it is becoming a tool for risk diversification. Growing institutional interest is driving the acceleration of coin prices. Subscribe to our Telegram channel
What is EPIC CASH? Epic Cash is the final point in the journey toward true P2P internet cash, the cornerstone of a private financial system. The Epic currency aims to become the world’s most effective privacy-protecting form of digital money. In order to fulfill that goal, it satisfies the three principal functions of money: 1. Store of Value — can be saved, retrieved, and exchanged at a later time, and of predictable value when retrieved; 2. Medium of Exchange — anything accepted as representing a standard of value and exchangeable for goods or services; 3. Unit of Account — the unit by which the value of a thing is accounted for and compared. Website: http://epic.tech Whitepapers: http://epic.tech/whitepaper Epic Cash Community: https://t.me/EpicCash Miner Chat: https://t.me/EpicMiners Gitlab: gitlab.com/epiccash Twitter: twitter.com/EpicCashTech Social Media: http://epic.tech/social-media Exchanges: https://epic.tech/service-list Oleg✌🏻 Hello community! Our AMA with EPIC begins🚀 We are very happy to have you here, on our joint AMA👌 So, lets start! The very first question for you. Can you introduce yourself? Max Freeman | Epic Cash | Mimblewimble I’m Max Freeman, which stands for “Maximum Freedom for Mankind” — we believe that the existing fiat money system enslaves people by unfairly confiscating their wealth through inflation. By using an honest money system such as Epic, we can improve the quality of life for billions of people worldwide. Yoga Dude Hello, I am Yoga Dude 🙂 I handle Marketing and PR, in crypto since 2011 started as Bitcoin miner, and in 2014 in Monero, and in 2015 in Ethereum, oh and briefly in DOGE for fun and unexpected profit. Heard about Epic Cash while learning about the Mimblewimble algo and joined the team last year. JLong I am John, Doing the general engineering and managerial work Max Freeman | Epic Cash | Mimblewimble I have been involved in early stage cryptos for the past 3 years, after building a global trading business for the past 20 years. Oleg✌🏻 nice to meet you🙂 Max Freeman | Epic Cash | Mimblewimble Epic is a decentralized community project like Bitcoin or Monero, there is no central authority or corporation involved. We had no ICO and no premine, we had a fair launch at 0 supply last September. Yoga Dude Great to meet everyone :) Oleg✌🏻 Here we go the 1st question for you ~ 1. What is Epic Cash about? Yoga Dude Epic Cash is designed to fulfill Satoshi’s original vision of P2P electronic cash, adjusting for what we learned from Bitcoin, a medium of exchange that is fast, free, open to all, while being private and fungible. We launched in September 2019 as a Proof of Work mineable crypto, without an ICO or a premine. Oleg✌🏻 Look like a real Bitcoin🙂 Yoga Dude with privacy and fungibility 😄 Oleg✌🏻 Sounds cool! move on to the next question… 2. What makes Epic Cash better than Monero or other privacy coins? Max Freeman | Epic Cash | Mimblewimble First off, we have a lot of respect for Monero and other privacy coins, we learned a lot from what they did right and what they did wrong, Our blockchain is much lighter than Monero or Bitcoin, our transaction engine is faster than Monero or ZCash. We use a three mining algo approach to allow more users the ability to obtain Epic Cash. We are a new, highly undervalued, coin and we look great not only for future use but for today's investment. Our blockchain is 90+% smaller than Monero or Bitcoin. Coins such as Zcash have optional privacy. Epic makes all transactions private, and it is impossible to trace movements of coins by watching wallet addresses. Oleg✌🏻 Young and hot😋 security and privacy level is very important now but… 3. Why copy the same supply economics as Bitcoin? Yoga Dude It is hard to compete with the success of Bitcoin today, part of the elegance and the appeal of Bitcoin is the responsible emission rate, terminating at 21million highly sub dividable coins. Like the Bitcoin supply curve, Epic Cash encourages early adopters, and with subsequent halvenings maintains a gradually diminishing flow of additional currency while preserving the overall value. Max Freeman | Epic Cash | Mimblewimble In 2028, the supply of Epic matches that of Bitcoin and they stay in sync until the final coin is mined in 2140. We have 4 halvenings between now and then, which is demonstrated in Bitcoin to drive the value over market cycles. Epic is a chance for people who were late to Bitcoin to ride the wave and not miss their opportunity this time. Oleg✌🏻 Interesting! 4. Why Choose Epic Cash over Grin and Beam? Max Freeman | Epic Cash | Mimblewimble First of all, we have tremendous respect for all Mimblewimble currencies and their talented teams, they all taught us a lot and we are thankful for that. Without sounding too contentious, the choice seems obvious. We offer the same core tech, but with a much more responsible emission curve — Grin is an endless fountain of emission and inflation (60 per second forever), and Beam is even more frontloaded outpacing even Grin’s aggressive emission schedule for the next several years… We respect Grin and Beam, we learned from them, and we believe we are the next evolutionary step. Additionally, as we mentioned earlier, we offer more ways to mine Epic Cash, both with GPU and CPU and ASICs, this gives us more potential users and miners, vs Grin and Beam that are only mineable with GPUs. Yoga Dude Yes, all that ☝️😄 Oleg✌🏻 I hope the miners read it all carefully 👌 Next question 5. Why have a development fund tax and what will it be used for? Yoga Dude Dev fund tax today is at a reasonable 7.77% dropping by 1.11% every year until it hits zero. As Epic Cash grows in value these funds will become increasingly more relevant in additional technical, marketing, and fintech partnerships developments. Oleg✌🏻 Very smart! 6. What is the advantage of 3 mining algorithms? Max Freeman | Epic Cash | Mimblewimble By having multiple mining algorithms we are able to attract CPU, GPU, and ASIC miners simultaneously. Currently all other Mimblewimble currencies are mineable with GPU only ignoring a large segment of CPU miners. Monero made a splash migrating to the RandomX CPU mining algo. Epic Cash from the beginning embraces all mining communities. Many miners are successfully using older hardware such as Xeon processors to help secure the network. We use RandomX for CPU, ProgPow for GPU, and Cuckoo for ASIC. Longer term, our flexible architecture means we can have many algorithms, not just 3. Our roadmap includes an allocation for SHA3 Keccak, which will help further decentralize the network and keep it unstoppable. Yoga Dude We love miners 🙂 and Epic Cash can be mined with laptops and gaming rigs 🙂 Oleg✌🏻 A wide selection of mining methods is a great way to create a stable, decentralized and large network👌 Let’s talk about persons… 7. Who are the people developing Epic Cash? Yoga Dude We are blessed with a very talented team of skilled developers with diverse backgrounds, many of them are volunteers who believe in what Epic Cash stands for and contribute with product and usability innovation. Our teams main focus is to make Epic Cash the best, most secure, most user friendly and usable product on the market, without making it unnecessarily techie, with as much mainstream user appeal as possible. This is a serious challenge but we are up for it 😄 Max Freeman | Epic Cash | Mimblewimble It is also important to note that we are a truly open ecosystem that anyone can participate in. Our community has developed wallets, mining pools, educational content, and much else besides. We are not limited by the funding generated during an ICO or VC investment, our users are an essential element of our team. Oleg✌🏻 Sounds very attractive. 8. What do you think is currently lack in today’s crypto? Max Freeman | Epic Cash | Mimblewimble We believe there is not enough privacy, anonymity and fungibility, although there is a growing awareness in the community as to why these are necessary. People are waking up to the fact that privacy is a right for everyone but today it is being exploited and violated by corporations, governments and unscrupulous individuals. Privacy does not mean that you have something to hide. We have doors on our houses, curtains on our windows, we wear clothes, and we have security on our bank accounts and businesses, not because we are criminals. Fungibility (the property of not being able to distinguish one unit of currency from another) also has become a hot issue as people have started to get in trouble because of someone else’s misdeeds. Tainted money (coins that are blacklisted or restricted) is a problem for Bitcoin and Ethereum, the top two cryptos today. Mimblewimble eliminates the risk of tainted coins making them indistinguishable from each other. With traceable coins, you always have to worry if the coins you are getting were involved in a hack, or perhaps the darknet. Oleg✌🏻 It’s good to see strong and safe coin in our time Let’s talk about your future… 9. What does the Epic Cash roadmap look like going forward? Yoga Dude First and foremost, we are focused on security and usability. We are working on a new, improved GUI wallet to incorporate the community feedback on ways to improve it. We are in the process of completing final testing phases for the next iteration of Epic Cash which will make it more secure and stable. Once that is done, we will be rolling out Android and iOS support to make Epic Cash usable on leading smartphones and smartwatches. Beyond that without going into too much detail we are focused on continuous evolution of privacy, ease of mining, and overall speed and usability. And of course we are constantly looking to add more exchanges both with and without KYC. Oleg✌🏻 Are you working on Android and IOS wallet ? What will your application be? Max Freeman | Epic Cash | Mimblewimble Yes, we will release a mobile wallet this year. It will bring us one step closer to people being able to actually use cryptocurrency as money in daily life. Yoga Dude The idea is to be able to access Epic Cash from any platform and device Max Freeman | Epic Cash | Mimblewimble Epic is very lightweight, which means that low-end devices such as smartwatches can participate. Oleg✌🏻 Ok, got it. Thanks for clarification! 10. What else can you tell us about Epic Cash? Max Freeman | Epic Cash | Mimblewimble Well one thing I really want to mention is our great Epic Cash community. We’ve been building a decentralized community organically, without the talk of price pumps, pressure to HODL and other BS crypto-gimmicks. Our community is truly global and consists of developers, volunteers, miners, and other Epic enthusiasts spreading the word about Epic Cash, helping us reach millions of people around the world to improve their quality of life through social media and directly. Everyone is an evangelist, everyone is an influencer, everyone has the power to make the world a better place to live in. As we continue to grow — the future looks Epic 😊 Yoga Dude Definitely the community! We got a talented crowd of very cool and motivated people from all over the world! Oleg✌🏻 Thank you guys, for such informative answers 🙂 Now we proceed to Section 3, where a Community can ask their questions to the EPIC team Now I’ll open chat for the quite some time … Oleg✌🏻 Thank you all, dear community! EPIC team, please choose the 10 best questions you want to answer. AngeI Everyone likes Privacy & Epic Cash provides their Best Privacy to users But, Which Technologies are being used by Epic Cash to make Blockchain very Private and Completely untrackable ? Max Freeman | Epic Cash | Mimblewimble From the wallet to the node, Epic uses Dandelion++ to bounce transactions around the world before they go into the mempool for mining. Within the blockchain itself, Cut-Through merges all transactions in a block together, with CoinJoin automatically mixing all coins. Beyond that, there are no addresses, so it’s impossible to watch someone’s wallet. Arnold Even litecoin is implementing mimblewimble, Don’t you think it’s a significant threat for Epic if they implement it, then why would anyone use a less popular and a new cryptocurrency. Max Freeman | Epic Cash | Mimblewimble LTC is implementing mw as an “extension block”, meaning that it is optional and not all transactions will use it. This is very different than the core protocol leveraging mw to make all transactions private and all coins fungible. Aluta Why Epic cash so much focus on fungibility? Does fungibility matters that much? Max Freeman | Epic Cash | Mimblewimble Fungibility is going to be one of the key issues within the cryptocurrency space in the coming years. Today, if you accept traceable coins from a seller, you are liable if they have ever been used in any illegal activity. This has led to a two tier market where freshly minted coins sell for more than circulated coins. When coins are fungible, like Epic, you don’t have to worry that you will run into a problem when an exchange or merchant blocks your transaction. Joxes It is a pleasure. When I first researched EpicCash, google showed me a youtube video that talked about how to mine with EpicCash. It made me ask: is this mining activity profitable so far? We are in the early stages of development I guess, what adoption strategies are you taking to have sustained growth? is it feasible to reach N ° 500 rank in coinmarketcap in the medium term? Yoga Dude When I got into crypto, it was by mining Bitcoin back in 2011 when you could still solve blocks on a single computer, but Bitcoin at the time was anything but profitable 😄 Today Epic Cash is still new, still young, and still undervalued. I believe it is mining-worthy because of its potential, not because of today’s price. By allowing Epic Cash to be mined with GPU and CPU on gaming rigs, servers, and even laptops we offer maximum public participation in our project. More people involved in the project, the more evangelists there are. We empower people to mine Epic Cash and to promote it. S.P.A.D.E What new features of Epic Cash provide that Grin or Beam does not offer. Why do we need Epic Cash? Max Freeman | Epic Cash | Mimblewimble They are great coins, but there are some ways in which Epic improves. Epic has better tokenomics than Grin and a more sustainable model than Beam, that has a company behind it that needs to repay investors via its high dev tax. this article explains in more detail https://medium.com/@frodofreeman/overview-of-mimblewimble-cryptocurrencies-7c70be146f50 Sahil What’s the Minimum Hardware / setup Required for Mining of EPIC Cash coins? Is Mining Profitable and Can we Mine EPIC Cash coins at Home? Max Freeman | Epic Cash | Mimblewimble It is possible to mine on an ordinary laptop or desktop from the last 5 years, sometimes older. Epic is open to everyone, and our friendly community is standing by to help you get started at t.me/epicminers Erven James Sato “TOKEN BURN” is BENEFECIAL for any projects, in able to CONTROL THE NUMBER OF TOKEN CIRCULATION and TO PROVIDE GREATER INCENTIVES TO INVESTORS. Does your GREAT PROJECT have plan about TOKEN BURN? Xenolink For deflating projects It is beneficial to drive the demand / scarcity / and price up in a faster pace. Epic Cash is here for the organic long run not the short run. However when it comes to long term economics elastic supplies whether inflating or deflating will not be a solid long term economic model. This has been heavily discussed already with Bitcoins inelastic Fixed 21 million supply in the past. Having a fixed model demonstrates good long term economics without worrying about balancing a deflating/inflating model. Bitcoin is a perfect example of a 21 million inelastic fixed supply model that has been proving itself till today. Which is why we are also using the same fixed 21 million supply model. Epic Cash plans to have a solid organic long term future to bring free private fungible money and make this world a better place. Red Z🔥🤙 No one predicted the COVID-19 pandemic while developing their business model. But the crisis and recession of the global economy is our present with you and it affects all sectors, including blockchain. Will you make or have already made changes to the project roadmap, tokenomics? Do you have a plan in case the situation does not improve in the coming months and will affect the crypto industry even more? Yoga Dude One thing we have seen as the result of the COVID-19 is more governments are talking about moving to digital cash — digital dollar in USA, digital Lira in Turkey, etc… If in the past the idea of digital money was not graspable by some people, today its the governments that are educating the people for us about the value of digital currency… What is ironic, the governments, by printing money to solve the economic consequences of COVID-19 also educating the consumer about the true “value” of fiat… What we offer is a touch free, borderless, private, anonymous, fungible currency that can not be printed beyond the initial defined algo. We are more responsible than the printing presses of the governments 🤔 kunlefighter How does the Dandelion++ Protocol, Confidential Transactions (CT) and CoinJoin assist in protecting the privacy of individuals and their transactions on Epic Cash Blockchain? Max Freeman | Epic Cash | Mimblewimble Dandelion++ bounces transactions around before committing them to the blockchain, making it impossible to determine where they originated from. Confidential Transactions means that all tx are private, you can’t tell anything about where the coins have been or who they belonged to. CoinJoin in essence melts down and re-mints each coin every time it is used, making it impossible to track their ownership or usage history. Epic provides comprehensive privacy to everyone, without the compromises that other pre-mimblewimble coins have. Dr Mönica Hello sir @maxfreeman4@Johnsstec@Yogadude Thanks for the ama I notice that Epic Cash has 2 type of new algorithm, progPoW version 0.15.0 and randomX version 1.0.3 NOW , CAN you tell me why you choose these 2 algorithm??? Yoga Dude We went with RandomX because it is a solid and very popular CPU centric algo used by several coins — most recently Monero. Most miners today heavily favor ASICs or GPUs, leaving a lot of solid high end users in the dust unable to mine emerging cryptos. As far as ProgPow, again its an established algo for GPU miners, and thanks to many cryptos starting with Bitcoin/Monero/Ethe etc there is no shortage of GPU rigs out there :) plus again the casual user with a video gaming caliber card can get in on the action. Oleg✌🏻Perfect!It was a great AMA, but it is coming to an end, thanks to everyone who was with us. Thanks EPIC team for taking the time👏. I hope our projects will be able to collaborate even more closely in the future and achieve new successes. Cheers!🎉
Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network
Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value? So let's have a short history of various payment channel techs!
Generation 0: Satoshi's Broken nSequence Channels
Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product. Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger. Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore. In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction. So what you'd do would be something like this:
You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
Eventually you have to stop drinking. It comes down to one of two possibilities:
You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time. Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
I think I got sidetracked here.
Bears are bad news.
You can't reasonably invoke "Satoshi's Vision" and simultaneously reject the Lightning Network because it's not onchain. Satoshi's Vision included a half-assed implementation of payment channels with nSequence, where the onchain transaction represented multiple logical payments, exactly what modern offchain techniques do (except modern offchain techniques actually work). nSequence (the field, but not its modern meaning) has been in Bitcoin since BitCoin For Windows Alpha 0.1.0. And its original intent was payment channels. You can't get nearer to Satoshi's Vision than being a field that Satoshi personally added to transactions on the very first public release of the BitCoin software, like srsly.
Miners can totally bypass mempool rules. In fact, the reason why nSequence has been repurposed to indicate "optional" replace-by-fee is because miners are already incentivized by the nSequence system to always follow replace-by-fee anyway. I mean, what do you think those drinks you passed to Jihan Wu are, other than the fee you pay him to mine a specific version of your transaction?
Satoshi made mistakes. The original design for nSequence is one of them. Today, we no longer use nSequence in this way. So diverging from Satoshi's original design is part and parcel of Bitcoin development, because over time, we learn new lessons that Satoshi never knew about. Satoshi was an important landmark in this technology. He will not be the last, or most important, that we will remember in the future: he will only be the first.
Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is). Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender. Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender. First, you and the bartender perform this ritual:
You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds. So now you start ordering in this way:
For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
You sign the transaction and pass it to the bartender, who serves your first drink.
For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
At the end:
If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen. So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx... Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly. "I'm refusing service to you," the bartender says. "Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!" "Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed." "What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer. What you see shocks you. "What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!" "Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW." Lesson learned?
Payback's a bitch.
Transaction malleability is a bitchier bitch. It's why we needed to fix the bug in SegWit. Sure, MtGox claimed they were attacked this way because someone kept messing with their transaction signatures and thus they lost track of where their funds went, but really, the bigger impetus for fixing transaction malleability was to support payment channels.
Yes, including the signatures in the hash that ultimately defines the txid was a mistake. Satoshi made a lot of those. So we're just reiterating the lesson "Satoshi was not an infinite being of infinite wisdom" here. Satoshi just gets a pass because of how awesome Bitcoin is.
CLTV-protected Spilman Channels
Using CLTV for the backoff branch. This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015. Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed. This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction. With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to. Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time". With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.
Todd Micropayment Networks
The old hub-spoke model (that isn't how LN today actually works). One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel. Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable. So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user). In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today. Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy. Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.
Poon-Dryja Lightning Network
Bidirectional two-participant channels. The Poon-Dryja channel mechanism has two important properties:
No time limit.
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel. The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online. Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want. Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening. With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow. I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere. There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
You have to store all the revocation keys of a channel. This implies you are storing 1 revocation key for every channel update, so if you perform millions of updates over your entire lifetime, you'd be storing several megabytes of keys, for only a single channel. RustyReddit fixed this by requiring that the revocation keys be generated from a "Seed" revocation key, and every key is just the application of SHA256 on that key, repeatedly. For example, suppose I tell you that my first revocation key is SHA256(SHA256(seed)). You can store that in O(1) space. Then for the next revocation, I tell you SHA256(seed). From SHA256(key), you yourself can compute SHA256(SHA256(seed)) (i.e. the previous revocation key). So you can remember just the most recent revocation key, and from there you'd be able to compute every previous revocation key. When you start a channel, you perform SHA256 on your seed for several million times, then use the result as the first revocation key, removing one layer of SHA256 for every revocation key you need to generate. RustyReddit not only came up with this, but also suggested an efficient O(log n) storage structure, the shachain, so that you can quickly look up any revocation key in the past in case of a breach. People no longer really talk about this O(n) revocation storage problem anymore because it was solved very very well by this mechanism.
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network. Lessons learned?
We can decentralize if we try hard enough!
"Hubs bad" can be made "hubs good" if everybody is a hub.
Smart people can solve problems. It's kinda why they're smart.
After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time. The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory). Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough. Lessons learned?
Bitcoin offchain scaling is more powerful than you ever thought.
A hybrid crypto exchange is a platform that provides users with access to their private keys and aims to solve the scalability issues of decentralized exchanges. *Disclaimer: I don’t insist that one have to store 100% of the portfolio on any kind of exchange. Why is it called Hybrid exchange? Hybrid crypto exchanges combine the pros of Centralized crypto exchanges and Decentralized crypto exchanges. The hybrid concept allows for certain cons to be remedied by implementing the advantages of the opposite. What are Centralized and Decentralized exchanges? Centralized(CEX) crypto exchanges provide massive volatility with the help of market-making activities. Occasional fiat gateways for its users, so everyone could quickly cash out gainings. Besides, substantial centralized crypto exchanges have a higher trust score within the community. Decentralized(DEX) crypto exchanges provide a solution to the security issues by letting users be in control of their private keys. This feature is a part of the real decentralization of trust philosophy, which is essential for the whole crypto economy. DEX vs CEX
Decentralized nature - in contrast to CEX, mostly DEXes are hosted on decentralized servers. This method of hosting makes them almost invulnerable to hacks;
Not restricted by law- because of its decentralized nature. There is no so-called single point of failure. It is nearly impossible to shut one down or regulate it. This is a strong point for users who live in countries that ban cryptocurrencies. But it’s really hard to find the independent Decentralized exchange. For example, IDEX which labels itself as DEX is a custodial exchange and is now sort of putting accounts and KYC into place. KYC is required for withdrawals of greater than 5,000$
Privacy - most CEXes requires users to go through a KYC process, which requires one to upload an ID. Without KYC procedure user can’t withdraw his funds. Unlike CEXes, DEXes requires an email address and nothing more, you even can think up a custom identity for it;
User responsibility - CEXes store all funds located on their platform on custody wallets which can potentially be a vulnerable target for hackers. However, DEXes allow users to be in full control over their funds. All that is needed to access a DEX is for a user to connect his wallet based on some mechanic (private key, metamask, json). This is the true nature of decentralization, blockchain is supposed to cut off third parties that collect fees for holding your funds.
On the one hand, DEX’s provide higher security and privacy for its users, but those aren't the only things we are looking for. On the other hand, CEX’s, as I told earlier, have a higher trust score, so what does this mean exactly?
Resources - currently CEX’s have more resources. Hence they can deliver a better user experience for its users. CEX’s are generally much more popular than DEXes. Though, DEXes are still an option B, and frequently used by those who do not trust the management of centralized exchanges due to human factors such as breach of internal controls and fraud..
But is their royalty deserved? “I definitely hope centralized exchanges go burn in hell as much as possible,” Vitalik Buterin stated in 2018. In particular, he thinks there’s no reason some projects need to pay $10 to $15 million(as per 2018) in listing fees to let people trade their tokens on centralized exchanges. This feels like a blood diamonds issue in the diamond industry. Most of those platforms were built on lies, some of them are currently building themselves out on falsehoods.
Ownership transparency - DEX’s were created to avoid regulatory pressure. Thus DEX founders' prefer to remain anonymous. Of course, this doesn't contradict decentralization, but users always have to remain skeptical when it comes to their funds.
CEXs have to be regulatory compliant, it’s impossible to be obedient without registering a company, submitting documents for proof of identity, etc. Most of the legal registries are opened to the public. Hence the founders are publicly known individuals. Besides, there is no need to hide while you are compliant and not involved in illegal activities.
Due diligence - Large CEX’s always do research on projects prior to listing, or even hosting an IEO for them. This leads to vast FOMO, users don't hesitate to do their own research and line up to for an investment opportunity. Currently, Binance is the most prosperous platform regarding IEO investments. DEXes dont host IEOs due to their decentralized nature and user anonymity. Usually, if one wants to participate in an IEO, a KYC process is required.
Easy to use - DEX’s frequently have convoluted interfaces, which is one of the considerable bottlenecks for new investors. In contrast, CEX’s are built for relative ease of use by experienced traders and newbies.
If you are new to this industry, or do not want to understand the intricacies of blockchains and came here to trade Bitcoin, I advise you to use a CEX. But If you came here for the tech, you will enjoy reading this more. What is the hybrid crypto exchange approach? Not so long ago, I decided to dive into the topic of hybrid exchanges as a potential game-changer in the cryptocurrency industry. The hybrid exchange philosophy builds on the strengths of decentralized and centralized exchanges. During my research, I came across a curious example - NEXT.exchange To further simplify the process of understanding the principles of hybrid exchanges, I propose to consider this topic by case. It’s worth noting that there is much to contemplate in regards to hybrid exchange platforms, their solutions and approaches may vary. There are also not many out there. DEX pros within NEXT:
Transparency - Unlike DEX’s that use decentralized or cloud servers, NEXT.exchange will use its own blockchain - NEXT.chain, based on SYS, DASH, and BTC, which in turn will allow the platform to expand on its transaction throughout (occasionally DEX’s majority of which are ETH based, experience hang time when the Ethereum network is overloaded with transactions).
Essentially NEXT.chain will be used by the exchange as an open database that stores information about all transactions and tokenized assets (assets created on NEXT.chain are dubbed 00X standard) within the exchange. To maintain the blockchain, investors will deploy 100 master nodes during the first year (79 out of 100 are already functioning).
Hybrid mining POW/POS - Each successfully executed order will be a transaction for mining. An interesting fact is that the issue of the exchange token will be carried out by mining, in a similar way to how it happens on the bitcoin network. Master nodes & miners will receive rewards for their contribution to the ecosystem.
Governance - the NEXT team is looking to provide Masternode operators with the opportunity to participate in the management of further development of the exchange and hybrid ecosystem by means of voting. How exactly this feature will be implemented remains a mystery, but sounds fair.
User confidence - the team plans on providing users with access to their wallet private keys. Additionally, they aim to involve an escrow services (similar to Kucoin) on their platform. Below is a brief schematic of their system and how NEXT.chain will factor in. Seems the goal is to tokenize assets using their chain, similar to Binance.
Privacy - Traders will be able to trade crypto-crypto without going through the KYC procedure, which is great for users. But the regulatory landscape may change over time. KYC will be needed for anything involving fiat.
CEX pros within NEXT:
Ownership transparency - Legal entity is registered in the Netherlands. All information about the team is publicly available on their site and on linkedin.
Fiat gateway - Presence of a legal entity allows the exchange to enable its users to withdraw their crypto assets to fiat and to trade several cryptocurrencies against fiat.
However, to do this, users will have to go through KYC (Yes, the guys from NEXT have some workings with banks to provide their users with access to USD and EUR. Other currencies will probably be available later). Thus, traders will be able to withdraw funds directly to Bank cards. As far as I am aware, they also plan to make PayPal available for withdrawals only.
High-quality community support - When I found myself in their community, I was surprised by the quality of support, I have not seen this even in TIER-1 exchanges. The team members eagerly answered all my questions. And the people in the chat were wonderful and kind.
It’s important to note that NEXT is just at its start, and will be releasing a huge update dubbed 2.0 (after a testing period with its community), so if hybrid cryptocurrency exchanges are interesting to you - then this is definitely one to keep an eye out for. Summing up Recently, the industry of centralized crypto-exchanges is literally filled with scammers. Teams of second-rate centralized exchanges "draw" trading volumes and even IEO results. Unfortunately, many blindly believe them. This is going to be a massive problem in the future, more important than you can imagine. Those scam exchanges will become more prominent and will swindle more people, this will lead to a severe outflow of defrauded people from the industry, which can not afford it. Hybrid cryptocurrency exchanges are a new trend that I think can improve the whole industry. Not all hybrid exchanges have their own blockchain, NEXT was considered as the project most suitable for the description of a hybrid cryptocurrency exchange. Don't FOMO and don't hesitate to do your own researches before depositing funds on the exchange wallets or participating in an IEO.
Concern about Ledger Nano X Bluetooth exposes massive blockchain signature/hardware wallet misunderstanding
I've been seeing lots of comments about people's concerns related to the bluetooth functionality, so I've took it upon myself to review how digital signatures work, and how hardware wallets sign digital transactions securely. I happen to believe the outcry exceeds the actual risk involved. One of a cryptocurrency wallet's main job is to sign digital messages (or transactions). What does that mean? It means when I want to send BTC to some address, I create an unsigned transaction. This transaction, in its most simplistic terms, just says how much and to whom I wish to send BTC to. The wallet runs a signature algorithm on that unsigned transaction to create a signed transaction. If you've ever used MyEtherWallet, you can see the unsigned vs. signed transaction when you try to send tokens. Whether it's a hardware or software wallet, the wallet takes your private key/seed, runs the signing algorithm on your unsigned transaction with your private key, then outputs your signed transaction. This signed transaction is just a long string of data that doesn't actually have your private key but has been altered by it. The beauty is as long as someone has your public key (that corresponds to your private key) along with the signed transaction, they can easily verify that the person who holds that private key approved that transaction. This is all without ever exposing the private key. So to sum up, I create an unsigned transaction that says who I want to sending something to, I use my wallet to run a signing algorithm on it with my private key, the wallet outputs the signed transaction without ever exposing the key. This signed transaction is broadcasted to the miners/stakers to verify and execute the transaction. See more info on bitcoin signatures here. Neither the unsigned nor the signed transactions contain your private key. Now how does this apply to a hardware wallet? Your software wallet, or MEW, or Ledger Live generates the unsigned message, sends it to your hardware wallet, which in turn signs the transaction on a secure chip that holds the private key, then sends back the signed message to your computer for broadcasting to the network. Bluetooth will allow the unsigned and signed transactions to flow wirelessly. And as we discussed above, the private key is never exposed in the unsigned or signed transactions. As long as the screen is showing what you're signing, you can never accidentally sign a transaction that sends your precious assets to some other address. Next, the communications between your ledger nano x and computephone/tablet are encrypted. So even if someone was even somehow able to decrypt that wireless data, it would only be unsigned/signed transactions which would be worthless to them anyway! But an individual seeing that data is as likely as them trying to see data between you and your bank (HINT: very unlikely, look up HTTPS). We are operating under the assumption that the hardware wallet has not been compromised, but that's true right now anyway. You guys don't have any reason to be afraid as long as you trust ledger to perform the appropriate security measures and code vetting. So far, they've done pretty well. EDIT: To visualize how a hardware wallet works, here's a diagram i quickly made in paint. EDIT2: I'll remove mean words.
“Bitcoin is the currency of resistance.” Utopia Trivia – What was the Genesis Block’s Reward Per Thread? Look for the answers somewhere in this edition of TheMessage.
2 – A Deeper Look Inside The Rabbit Hole of Utopia – PART IV
In Part III we reviewed the meteoric rise and fall of Napster, followed by the birth of a truly Peer-to-Peer content sharing platform in the form of the BitTorrent protocol. We discussed how revolutionary a technology BitTorrent was and how integral to the Internet it has become. Now in Part IV, we will discuss what happens when the profoundly democratizing and resilient power of Peer-to-Peer technology is brought to bear on money itself. On October 31st 2008, the Bitcoin white paper is published and on January 3 2009, Bitcoin’s Genesis Block is mined. Previously, the idea of digital money could not be realized in a direct, trustless fashion, because there always existed the problem of multiple spending. A trusted, third party database was always necessary and that handicap held back the potential of digital money for many years. Satoshi Nakamoto proposed an elegant solution; through cryptography, a Peer-to-Peer network could maintain the integrity of the record and allow participants to transfer value between each other without having to trust any third party. The simple but profound act of one human being directly handing another human being something of unique value was now finally enabled online through the internet. The social, economic and political implications of this technological breakthrough are still be felt to this day. To understand how consequential a breakthrough Bitcoin was, you would need to appreciate how important a role money and its control plays in the lives of human beings. Most people today are born into societies where they have little choice in the matters of money. Decisions made by others many years ago affect their day to day lives in ways most do not understand. Human history is littered with examples of those in privileged positions abusing the power to create and regulate money to the detriment of the masses. Just as the power of communication and content sharing was placed in the hands of the people through Peer-to-Peer technology and the internet, now money itself was placed in the hands of the people through the P2P technology of Bitcoin. To participate in Bitcoin was itself a kind of defiant act against the existing power structures, a form of resistance–“Bitcoin is the currency of resistance.” Max Keiser, a broadcaster, film maker and Bitcoin proponent is quoted as saying. The modern history of the internet has taught us that with every advancement and empowering step forward for humanity, vested corporate and government interests seek to extend their domain of influence by exerting power and control in lock-step with those advancements and Bitcoin is no exception. The only solution to diminish this negative influence, projected via surveillance and its coercive power, has been the equalizing power of cryptography and the democratizing power of P2P technology. What if advancements in these two fields could be brought to bear on a new kind of internet? An internet where surveillance and censorship were absent? An internet where communication, content and money could all flow in complete security and privacy? That will be the subject of Part V, our final segment in this series of articles; the revolution of Utopia.
3 – Mining Rewards Adjustment on Block #8843
Background On the day of Utopia’s mainnet launch, November 18th 2019, the mining Reward Per Thread (and so the Genesis Block’s RPT) was set at 0.0128 CRP. It stayed set at a maximum of 0.0128 for approximately 3-4 weeks as the total thread count ballooned to over 30,000 and only marginally declined after 15,000 threads since the Total Reward Generated (TRG) was capped at 192 CRP per 15 minutes Block. It was because of the miner abuse associated with those initial weeks that a major update was released in mid-December mandating a bot be run on a system with a minimum specification of 4 CPUs and 4GB of RAM along with a Public IP. Once that new requirement was put in place, thread count collapsed from over 30,000 to less than 1,000. Within days, the team doubled the mining RPT to 0.0256 CRP in order to better incentivize users to operate bots on enhanced servers and support the network. Unfortunately version 1.0.5499 had serious issues with reward rate for miners and for 7 weeks users endured through inconsistent rewards until the much celebrated major update was finally released on Febraury 4th 2020. Major update version 1.0.5665 and minor update 5672 witnessed the thread count climb consistently from less than 1,000 threads to over 9,000 threads over the next 2 weeks. However, at 7,500 threads, when a number of users, this publisher included, expected to see a similar marginal decline in RPT as before, none was observed. The TRG number was apparently no longer capped at 192 as it previously had been, and the TRG saw its figure climb to as high as 230 CRP (equivalent to over 22,000 CRP per day) before the hammer came down. Utopia Monetary Policy At this point, it’s worth reviewing the 1984 Group’s purported monetary policy for Crypton and Utopia. In their own words: “Multi-faceted and highly-professional approach to liquidity support and stable market rate of Crypton is well-organized with 3 main levers:
Adjustable amount of issued Cryptons per 15 minute block for regulating emission
Adjustable Proof-of-Stake Rate for storing Cryptons that can be positive or even negative if it’s necessary for market rate stability
Adjustable fees settings for all paid services available within Utopia ecosystem
All of three adjustable settings listed above are currently controlled by Utopia development team but after implementation of decentralized referendum, self-governance and voting systems the full control of adjustable settings will be transferred to society.” The Hammer of Block #8843, RPT vs TRG On Block #8843 the team reduced the RPT from 0.0256 to 0.0096, a contraction of 62.5%, or a factor of 2.67. This happened on February 19th midday UTC time. According to a message sent by the team, “This measure is necessary for optimal total balance of mined Cryptons and for efficient CRP value support in current market conditions.”. Based on the team’s explanation, they did this in order to control the trajectory of total CRP in circulation (“optimal total balance of mined Cryptons”) as well as to provide support to the value of CRP in the market, (“efficient CRP value support in current market conditions”). Why they chose to exercise control at the RPT level rather than the TRG level is the most fascinating question to consider. Capping the TRG has the additional effect of marginally disincentivizing new threads, whereas reducing the RPT doesn’t have that negative marginal effect, it simply makes each thread less productive. While both would have a similar monetary or economic net effect, they provide different incentives to miners. By reducing RPT, miners are incentivized to find more cost-effective servers in the long run, while the addition of new threads continues to be incentivized in a similar fashion. Therefore, we can conclude that the team wants to see the thread count continue to multiply, but did not want to compromise the inflation of CRP to accomplish this. Furthermore, because the reward rate of mining bots is already relatively high, it can be concluded that the RPT is unlikely to ever see an increase again.

With the cost of mining CRP having increased by a factor of 2.67, TheMerchant is updating the price structure at TheMarket in order to better accommodate potential investors with different price sensitivities. The Normal high-volume selling price will now be $2.50/CRP. This will be the default price around the clock when not in the 14:00 to 22:00 UTC time slot on Saturdays. The Once-Per-Week high volume selling price will now be $2.00/CRP. This will be every Saturday except the final Saturday of the month, from 14:00 UTC to 22:00 UTC. (February 22, March 7, 14, 21, etc.) The Once-Per-Month high volume selling price will now be $1.50/CRP. This will be on the final Saturday of the month, from 14:00 UTC to 22:00 UTC. February 29, March 28, April 25 etc.) The reason for this price structure is that until a low-friction, high-volume exchange is established, there needs to be a reliable and predictable way to meet the needs of potential investors at different price points. Some investors have a long enough investment horizon that buying at $2.50 or $2.00 or $1.50 is not as important as being able to accumulate as much CRP as possible from a trusted source before the supply is exhausted. This investor would be considered more time-sensitive and less price-sensitive and more likely to acquire TheMerchant’s supply before others. Whereas other investors may have a shorter investment horizon and patiently waiting until the end of the week on Saturday, or quite possibly even until the end of the month on the final Saturday is more appealing to them, even at the risk of the supply having been reduced to completely exhausted, because they are more price-sensitive. In all cases, buy orders will be prioritized on a first-come, first-served basis.

I understand that most analogies that attempt to explain blockchain/bitcoin will be inherently incomplete/flawed since the technology is so new, but I still think they are critical for new participants to get a grasp on what’s happening, at least for me personally. Hoping to get some help as I am having trouble synthesizing a few concepts:
Private/public keys and digital signatures
Sequence of events
Order in which transactions are recorded
Mining nodes vs non mining nodes
My understanding is that all transactions are broadcast to the network. Initially I thought the distributed ledger was analogous to 4 individuals playing monopoly. Instead of having a banker, each player writes down whenever a transaction takes place. This particular analogy lead me to believe transactions were recorded in real time (a player shouts out their transaction and immediately all players record the transaction). Learning about the proof of work lottery required me to tweak my understanding a bit. (Except in the case of forking) I gather that only one individual in the entire network is mining a block (recording transactions) at any given time? Not sure if this is true, but assuming it is, that person records transactions in time sequential order (or so I thought). Somehow a public and private key are involved here: I decided a public and private key are analogous to a username and password (I think this is grossly over simplified). Anyway, providing the password that corresponds with your username allows you to conduct transactions (digital signature). There is some validation of each transaction before the transaction reaches the miner (mechanisms here are unclear). As stated above, I was initially under the impression that the miner is recording transactions in time sequential order, but then I remembered transactions fees. This lead me to think of transaction fees like bidding on eBay: the higher transaction fee you pay moves your transaction to the top of the list. Therefore transactions are not recorded in real time. When your block is full (is there a certain GB limit?) the network validates that everything checks out. You get a lil piece of the action (deposit of transactions fees and a reward for mining a block into your wallet). The proof of work lottery begins again. Two unanswered questions remain:
Is the proof of work lottery “paused” while someone is actively mining a block?
I have become exposed to the idea of mining and non mining nodes... what exactly is a non mining node? Someone who conducts (and validates) transactions but doesn’t play in the proof of work lottery? Or just pretty much everyone who owns bitcoin but is not set up for mining?
Very grateful to anyone who can check my understanding. Most of what I've learned comes from the ebook Inventing Bitcoin, this Hackernoon article that dives a bit deeper into validation, and this 3Blue1brown Youtube video that provides a high level review of foundational concepts. In addition I've been watching the Khan Academy series on Bitcoin, and listening to the Unchained podcast pretty religiously, however since I still feel uncertain on these introductory topics, I feel like I can't be totally engaged with new content.
Your Guide to Monero, and Why It Has Great Potential
/////Your Guide to Monero, and Why It Has Great Potential/////
Marketing. It's a dirty word for most members of the Monero community. It is also one of the most divisive words in the Monero community. Yet, the lack of marketing is one of the most frustrating things for many newcomers. This is what makes this an unusual post from a member of the Monero community. This post is an unabashed and unsolicited analyzation of why I believe Monero to have great potential. Below I have attempted to outline different reasons why Monero has great potential, beginning with upcoming developments and use cases, to broader economic motives, speculation, and key issues for it to overcome. I encourage you to discuss and criticise my musings, commenting below if you feel necessary to do so.
Bulletproofs - A Reduction in Transaction Sizes and Fees Since the introduction of Ring Confidential Transactions (Ring CT), transaction amounts have been hidden in Monero, albeit at the cost of increased transaction fees and sizes. In order to mitigate this issue, Bulletproofs will soon be added to reduce both fees and transaction size by 80% to 90%. This is great news for those transacting smaller USD amounts as people commonly complained Monero's fees were too high! Not any longer though! More information can be found here. Bulletproofs are already working on the Monero testnet, and developers were aiming to introduce them in March 2018, however it could be delayed in order to ensure everything is tried and tested. Multisig Multisig has recently been merged! Mulitsig, also called multisignature, is the requirement for a transaction to have two or more signatures before it can be executed. Multisig transactions and addresses are indistinguishable from normal transactions and addresses in Monero, and provide more security than single-signature transactions. It is believed this will lead to additional marketplaces and exchanges to supporting Monero. Kovri Kovri is an implementation of the Invisible Internet Project (I2P) network. Kovri uses both garlic encryption and garlic routing to create a private, protected overlay-network across the internet. This overlay-network provides users with the ability to effectively hide their geographical location and internet IP address. The good news is Kovri is under heavy development and will be available soon. Unlike other coins' false privacy claims, Kovri is a game changer as it will further elevate Monero as the king of privacy. Mobile Wallets There is already a working Android Wallet called Monerujo available in the Google Play Store. X Wallet is an IOS mobile wallet. One of the X Wallet developers recently announced they are very, very close to being listed in the Apple App Store, however are having some issues with getting it approved. The official Monero IOS and Android wallets, along with the MyMonero IOS and Android wallets, are also almost ready to be released, and can be expected very soon. Hardware Wallets Hardware wallets are currently being developed and nearing completion. Because Monero is based on the CryptoNote protocol, it means it requires unique development in order to allow hardware wallet integration. The Ledger Nano S will be adding Monero support by the end of Q1 2018. There is a recent update here too. Even better, for the first time ever in cryptocurrency history, the Monero community banded together to fund the development of an exclusive Monero Hardware Wallet, and will be available in Q2 2018, costing only about $20! In addition, the CEO of Trezor has offered a 10BTC bounty to whoever can provide the software to allow Monero integration. Someone can be seen to already be working on that here. TAILS Operating System Integration Monero is in the progress of being packaged in order for it to be integrated into TAILS and ready to use upon install. TAILS is the operating system popularised by Edward Snowden and is commonly used by those requiring privacy such as journalists wanting to protect themselves and sources, human-right defenders organizing in repressive contexts, citizens facing national emergencies, domestic violence survivors escaping from their abusers, and consequently, darknet market users. In the meantime, for those users who wish to use TAILS with Monero, u/Electric_sheep01 has provided Sheep's Noob guide to Monero GUI in Tails 3.2, which is a step-by-step guide with screenshots explaining how to setup Monero in TAILS, and is very easy to follow. Mandatory Hardforks Unlike other coins, Monero receives a protocol upgrade every 6 months in March and September. Think of it as a Consensus Protocol Update. Monero's hard forks ensure quality development takes place, while preventing political or ideological issues from hindering progress. When a hardfork occurs, you simply download and use the new daemon version, and your existing wallet files and copy of the blockchain remain compatible. This reddit post provides more information. Dynamic fees Many cryptocurrencies have an arbitrary block size limit. Although Monero has a limit, it is adaptive based on the past 100 blocks. Similarly, fees change based on transaction volume. As more transactions are processed on the Monero network, the block size limit slowly increases and the fees slowly decrease. The opposite effect also holds true. This means that the more transactions that take place, the cheaper the fees! Tail Emission and Inflation There will be around 18.4 million Monero mined at the end of May 2022. However, tail emission will kick in after that which is 0.6 XMR, so it has no fixed limit. Gundamlancer explains that Monero's "main emission curve will issue about 18.4 million coins to be mined in approximately 8 years. (more precisely 18.132 Million coins by ca. end of May 2022) After that, a constant "tail emission" of 0.6 XMR per 2-minutes block (modified from initially equivalent 0.3 XMR per 1-minute block) will create a sub-1% perpetual inflatio starting with 0.87% yearly inflation around May 2022) to prevent the lack of incentives for miners once a currency is not mineable anymore. Monero Research Lab Monero has a group of anonymous/pseudo-anonymous university academics actively researching, developing, and publishing academic papers in order to improve Monero. See here and here. The Monero Research Lab are acquainted with other members of cryptocurrency academic community to ensure when new research or technology is uncovered, it can be reviewed and decided upon whether it would be beneficial to Monero. This ensures Monero will always remain a leading cryptocurrency. A recent end of 2017 update from a MRL researcher can be found here.
///Monero's Technology - Rising Above The Rest///
Monero Has Already Proven Itself To Be Private, Secure, Untraceable, and Trustless Monero is the only private, untraceable, trustless, secure and fungible cryptocurrency. Bitcoin and other cryptocurrencies are TRACEABLE through the use of blockchain analytics, and has lead to the prosecution of numerous individuals, such as the alleged Alphabay administrator Alexandre Cazes. In the Forfeiture Complaint which detailed the asset seizure of Alexandre Cazes, the anonymity capabilities of Monero were self-demonstrated by the following statement of the officials after the AlphaBay shutdown: "In total, from CAZES' wallets and computer agents took control of approximately $8,800,000 in Bitcoin, Ethereum, Monero and Zcash, broken down as follows: 1,605.0503851 Bitcoin, 8,309.271639 Ethereum, 3,691.98 Zcash, and an unknown amount of Monero". Privacy CANNOT BE OPTIONAL and must be at a PROTOCOL LEVEL. With Monero, privacy is mandatory, so that everyone gets the benefits of privacy without any transactions standing out as suspicious. This is the reason Darknet Market places are moving to Monero, and will never use Verge, Zcash, Dash, Pivx, Sumo, Spectre, Hush or any other coins that lack good privacy. Peter Todd (who was involved in the Zcash trusted setup ceremony) recently reiterated his concerns of optional privacy after Jeffrey Quesnelle published his recent paper stating 31.5% of Zcash transactions may be traceable, and that only ~1% of the transactions are pure privacy transactions (i.e., z -> z transactions). When the attempted private transactions stand out like a sore thumb there is no privacy, hence why privacy cannot be optional. In addition, in order for a cryptocurrency to truly be private, it must not be controlled by a centralised body, such as a company or organisation, because it opens it up to government control and restrictions. This is no joke, but Zcash is supported by DARPA and the Israeli government!. Monero provides a stark contrast compared to other supposed privacy coins, in that Monero does not have a rich list! With all other coins, you can view wallet balances on the blockexplorers. You can view Monero's non-existent rich list here to see for yourself. I will reiterate here that Monero is TRUSTLESS. You don't need to rely on anyone else to protect your privacy, or worry about others colluding to learn more about you. No one can censor your transaction or decide to intervene. Monero is immutable, unlike Zcash, in which the lead developer Zooko publicly tweeted the possibility of providing a backdoor for authorities to trace transactions. To Zcash's demise, Zooko famously tweeted:
" And by the way, I think we can successfully make Zcash too traceable for criminals like WannaCry, but still completely private & fungible. …"
Ethereum's track record of immutability is also poor. Ethereum was supposed to be an immutable blockchain ledger, however after the DAO hack this proved to not be the case. A 2016 article on Saintly Law summarised the problematic nature of Ethereum's leadership and blockchain intervention:
" Many ethereum and blockchain advocates believe that the intervention was the wrong move to make in this situation. Smart contracts are meant to be self-executing, immutable and free from disturbance by organisations and intermediaries. Yet the building block of all smart contracts, the code, is inherently imperfect. This means that the technology is vulnerable to the same malicious hackers that are targeting businesses and governments. It is also clear that the large scale intervention after the DAO hack could not and would not likely be taken in smaller transactions, as they greatly undermine the viability of the cryptocurrency and the technology."
Monero provides Fungibility and Privacy in a Cashless World As outlined on GetMonero.org, fungibility is the property of a currency whereby two units can be substituted in place of one another. Fungibility means that two units of a currency can be mutually substituted and the substituted currency is equal to another unit of the same size. For example, two $10 bills can be exchanged and they are functionally identical to any other $10 bill in circulation (although $10 bills have unique ID numbers and are therefore not completely fungible). Gold is probably a closer example of true fungibility, where any 1 oz. of gold of the same grade is worth the same as another 1 oz. of gold. Monero is fungible due to the nature of the currency which provides no way to link transactions together nor trace the history of any particular XMR. 1 XMR is functionally identical to any other 1 XMR. Fungibility is an advantage Monero has over Bitcoin and almost every other cryptocurrency, due to the privacy inherent in the Monero blockchain and the permanently traceable nature of the Bitcoin blockchain. With Bitcoin, any BTC can be tracked by anyone back to its creation coinbase transaction. Therefore, if a coin has been used for an illegal purpose in the past, this history will be contained in the blockchain in perpetuity. A great example of Bitcoin's lack of fungibility was reposted by u/ViolentlyPeaceful:
"Imagine you sell cupcakes and receive Bitcoin as payment. It turns out that someone who owned that Bitcoin before you was involved in criminal activity. Now you are worried that you have become a suspect in a criminal case, because the movement of funds to you is a matter of public record. You are also worried that certain Bitcoins that you thought you owned will be considered ‘tainted’ and that others will refuse to accept them as payment."
This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies. Monero has been built specifically to address the problem of traceability and non-fungibility inherent in other cryptocurrencies. By having completely private transactions Monero is truly fungible and there can be no blacklisting of certain XMR, while at the same time providing all the benefits of a secure, decentralized, permanent blockchain. The world is moving cashless. Fact. The ramifications of this are enormous as we move into a cashless world in which transactions will be tracked and there is a potential for data to be used by third parties for adverse purposes. While most new cryptocurrency investors speculate upon vaporware ICO tokens in the hope of generating wealth, Monero provides salvation for those in which financial privacy is paramount. Too often people equate Monero's features with criminal endeavors. Privacy is not a crime, and is necessary for good money. Transparency in Monero is possible OFF-CHAIN, which offers greater transparency and flexibility. For example, a Monero user may share their Private View Key with their accountant for tax purposes. Monero aims to be adopted by more than just those with nefarious use cases. For example, if you lived in an oppressive religious regime and wanted to buy a certain item, using Monero would allow you to exchange value privately and across borders if needed. Another example is that if everybody can see how much cryptocurrency you have in your wallet, then a certain service might decide to charge you more, and bad actors could even use knowledge of your wallet balance to target you for extortion purposes. For example, a Russian cryptocurrency blogger was recently beaten and robbed of $425k. This is why FUNGIBILITY IS ESSENTIAL. To summarise this in a nutshell:
"A lack of fungibility means that when sending or receiving funds, if the other person personally knows you during a transaction, or can get any sort of information on you, or if you provide a residential address for shipping etc. – you could quite potentially have them use this against you for personal gain"
Major Investors And Crypto Figureheads Are Interested Ari Paul is the co-founder and CIO of BlockTower Capital. He was previously a portfolio manager for the University of Chicago's $8 billion endowment, and a derivatives market maker and proprietary trader for Susquehanna International Group. Paul was interviewed on CNBC on the 26th of December and when asked what was his favourite coin was, he stated "One that has real fundamental value besides from Bitcoin is Monero" and said it has "very strong engineering". In addition, when he was asked if that was the one used by criminals, he replied "Everything is used by criminals including the US dollar and the Euro". Paul later supported these claims on Twitter, recommending only Bitcoin and Monero as long-term investments. There are reports that "Roger Ver, earlier known as 'Bitcoin Jesus' for his evangelical support of the Bitcoin during its early years, said his investment in Monero is 'substantial' and his biggest in any virtual currency since Bitcoin. Charlie Lee, the creator of Litecoin, has publicly stated his appreciation of Monero. In a September 2017 tweet directed to Edward Snowden explaining why Monero is superior to Zcash, Charlie Lee tweeted:
All private transactions, More tested privacy tech, No tax on miners to pay investors, No high inflation... better investment.
John McAfee, arguably cryptocurrency's most controversial character at the moment, has publicly supported Monero numerous times over the last twelve months(before he started shilling ICOs), and has even claimed it will overtake Bitcoin. Playboy instagram celebrity Dan Bilzerian is a Monero investor, with 15% of his portfolio made up of Monero. Finally, while he may not be considered a major investor or figurehead, Erik Finman, a young early Bitcoin investor and multimillionaire, recently appeared in a CNBC Crypto video interview, explaining why he isn't entirely sold on Bitcoin anymore, and expresses his interest in Monero, stating:
"Monero is a really good one. Monero is an incredible currency, it's completely private."
There is a common belief that most of the money in cryptocurrency is still chasing the quick pump and dumps, however as the market matures, more money will flow into legitimate projects such as Monero. Monero's organic growth in price is evidence smart money is aware of Monero and gradually filtering in. The Bitcoin Flaw A relatively unknown blogger named CryptoIzzy posted three poignant pieces regarding Monero and its place in the world. The Bitcoin Flaw: Monero Rising provides an intellectual comparison of Monero to other cryptocurrencies, and Valuing Cryptocurrencies: An Approach outlines methods of valuing different coins. CryptoIzzy's most recent blog published only yesterday titled Monero Valuation - Update and Refocus is a highly recommended read. It touches on why Monero is much more than just a coin for the Darknet Markets, and provides a calculated future price of Monero. CryptoIzzy also published The Power of Money: A Case for Bitcoin, which is an exploration of our monetary system, and the impact decentralised cryptocurrencies such as Bitcoin and Monero will have on the world. In the epilogue the author also provides a positive and detailed future valuation based on empirical evidence. CryptoIzzy predicts Monero to easily progress well into the four figure range. Monero Has a Relatively Small Marketcap Recently we have witnessed many newcomers to cryptocurrency neglecting to take into account coins' marketcap and circulating supply, blindly throwing money at coins under $5 with inflated marketcaps and large circulating supplies, and then believing it's possible for them to reach $100 because someone posted about it on Facebook or Reddit. Compared to other cryptocurrencies, Monero still has a low marketcap, which means there is great potential for the price to multiply. At the time of writing, according to CoinMarketCap, Monero's marketcap is only a little over $5 billion, with a circulating supply of 15.6 million Monero, at a price of $322 per coin. For this reason, I would argue that this is evidence Monero is grossly undervalued. Just a few billion dollars of new money invested in Monero can cause significant price increases. Monero's marketcap only needs to increase to ~$16 billion and the price will triple to over $1000. If Monero's marketcap simply reached ~$35 billion (just over half of Ripple's $55 billion marketcap), Monero's price will increase 600% to over $2000 per coin. Another way of looking at this is Monero's marketcap only requires ~$30 billion of new investor money to see the price per Monero reach $2000, while for Ethereum to reach $2000, Ethereum's marketcap requires a whopping ~$100 billion of new investor money. Technical Analysis There are numerous Monero technical analysts, however none more eerily on point than the crowd-pleasing Ero23. Ero23's charts and analysis can be found on Trading View. Ero23 gained notoriety for his long-term Bitcoin bull chart published in February, which is still in play today. Head over to his Trading View page to see his chart: Monero's dwindling supply. $10k in 2019 scenario, in which Ero23 predicts Monero to reach $10,000 in 2019. There is also this chart which appears to be freakishly accurate and is tracking along perfectly today. Coinbase Rumours Over the past 12 months there have been ongoing rumours that Monero will be one of the next cryptocurrencies to be added to Coinbase. In January 2017, Monero Core team member Riccardo 'Fluffypony' Spagni presented a talk at Coinbase HQ. In addition, in November 2017 GDAX announced the GDAX Digit Asset Framework outlining specific parameters cryptocurrencies must meet in order to be added to the exchange. There is speculation that when Monero has numerous mobile and hardware wallets available, and multisig is working, then it will be added. This would enable public accessibility to Monero to increase dramatically as Coinbase had in excess of 13 million users as of December, and is only going to grow as demand for cryptocurrencies increases. Many users argue that due to KYC/AML regulations, Coinbase will never be able to add Monero, however the Kraken exchange already operates in the US and has XMfiat pairs, so this is unlikely to be the reason Coinbase is yet to implement XMfiat trading. Monero Is Not an ICO Scam It is likely most of the ICOs which newcomers invest in, hoping to get rich quick, won't even be in the Top 100 cryptocurrencies next year. A large portion are most likely to be pumps and dumps, and we have already seen numerous instances of ICO exit scams. Once an ICO raises millions of dollars, the developers or CEO of the company have little incentive to bother rolling out their product or service when they can just cash out and leave. The majority of people who create a company to provide a service or product, do so in order to generate wealth. Unless these developers and CEOs are committed and believed in their product or service, it's likely that the funds raised during the ICO will far exceed any revenue generated from real world use cases. Monero is a Working Currency, Today Monero is a working currency, here today. The majority of so called cryptocurrencies that exist today are not true currencies, and do not aim to be. They are a token of exchange. They are like a share in a start-up company hoping to use blockchain technology to succeed in business. A crypto-assest is a more accurate name for coins such as Ethereum, Neo, Cardano, Vechain, etc. Monero isn't just a vaporware ICO token that promises to provide a blockchain service in the future. It is not a platform for apps. It is not a pump and dump coin. Monero is the only coin with all the necessary properties to be called true money. Monero is private internet money. Some even describe Monero as an online Swiss Bank Account or Bitcoin 2.0, and it is here to continue on from Bitcoin's legacy. Monero is alleviating the public from the grips of banks, and protests the monetary system forced upon us. Monero only achieved this because it is the heart and soul, and blood, sweat, and tears of the contributors to this project. Monero supporters are passionate, and Monero has gotten to where it is today thanks to its contributors and users.
///Key Issues for Monero to Overcome///
Scalability While Bulletproofs are soon to be implemented in order to improve Monero's transaction sizes and fees, scalability is an issue for Monero that is continuously being assessed by Monero's researchers and developers to find the most appropriate solution. Ricardo 'Fluffypony' Spagni recently appeared on CNBC's Crypto Trader, and when asked whether Monero is scalable as it stands today, Spagni stated that presently, Monero's on-chain scaling is horrible and transactions are larger than Bitcoin's (because of Monero's privacy features), so side-chain scaling may be more efficient. Spagni elaborated that the Monero team is, and will always be, looking for solutions to an array of different on-chain and off-chain scaling options, such as developing a Mimblewimble side-chain, exploring the possibility of Lightning Network so atomic swaps can be performed, and Tumblebit. In a post on the Monero subreddit from roughly a month ago, monero moderator u/dEBRUYNE_1 supports Spagni's statements. dEBRUYNE_1 clarifies the issue of scalability:
"In Bitcoin, the main chain is constrained and fees are ludicrous. This results in users being pushed to second layer stuff (e.g. sidechains, lightning network). Users do not have optionality in Bitcoin. In Monero, the goal is to make the main-chain accessible to everyone by keeping fees reasonable. We want users to have optionality, i.e., let them choose whether they'd like to use the main chain or second layer stuff. We don't want to take that optionality away from them."
"Monero has all the mechanisms it needs to find the balance between transaction load, and offsetting the costs of miner infrastructure/profits, while making sure the network is useful for users. But like the interviewer said, the question is directed at "right now", and Fluffys right to a certain extent, Monero's transactions are huge, and compromises in blockchain security will help facilitate less burdensome transactional activity in the future. But to compare Monero to Bitcoin's transaction sizes is somewhat silly as Bitcoin is nowhere near as useful as monero, and utility will facilitate infrastructure building that may eventually utterly dwarf Bitcoin. And to equate scaling based on a node being run on a desktop being the only option for what classifies as "scalable" is also an incredibly narrow interpretation of the network being able to scale, or not. Given the extremely narrow definition of scaling people love to (incorrectly) use, I consider that a pretty crap question to put to Fluffy in the first place, but... ¯_(ツ)_/¯"
u/xmrusher also contributed to the discussion, comparing Bitcoin to Monero using this analogous description:
"While John is much heavier than Henry, he's still able to run faster, because, unlike Henry, he didn't chop off his own legs just so the local wheelchair manufacturer can make money. While Morono has much larger transactions then Bitcoin, it still scales better, because, unlike Bitcoin, it hasn't limited itself to a cripplingly tiny blocksize just to allow Blockstream to make money."
Setting up a wallet can still be time consuming It's time consuming and can be somewhat difficult for new cryptocurrency users to set up their own wallet using the GUI wallet or the Command Line Wallet. In order to strengthen and further decentralize the Monero network, users are encouraged to run a full node for their wallet, however this can be an issue because it can take up to 24-48 hours for some users depending on their hard-drive and internet speeds. To mitigate this issue, users can run a remote node, meaning they can remotely connect their wallet to another node in order to perform transactions, and in the meantime continue to sync the daemon so in the future they can then use their own node. For users that do run into wallet setup issues, or any other problems for that matter, there is an extremely helpful troubleshooting thread on the Monero subreddit which can be found here. And not only that, unlike some other cryptocurrency subreddits, if you ask a question, there is always a friendly community member who will happily assist you. Monero.how is a fantastic resource too! Despite still being difficult to use, the user-base and price may increase dramatically once it is easier to use. In addition, others believe that when hardware wallets are available more users will shift to Monero.
I actually still feel a little shameful for promoting Monero here, but feel a sense of duty to do so. Monero is transitioning into an unstoppable altruistic beast. This year offers the implementation of many great developments, accompanied by the likelihood of a dramatic increase in price. I request you discuss this post, point out any errors I have made, or any information I may have neglected to include. Also, if you believe in the Monero project, I encourage you to join your local Facebook or Reddit cryptocurrency group and spread the word of Monero. You could even link this post there to bring awareness to new cryptocurrency users and investors. I will leave you with an old on-going joke within the Monero community - Don't buy Monero - unless you have a use case for it of course :-) Just think to yourself though - Do I have a use case for Monero in our unpredictable Huxleyan society? Hint: The answer is ? Edit: Added in the Tail Emission section, and noted Dan Bilzerian as a Monero investor. Also added information regarding the XMR.TO payment service. Added info about hardfork
2. Sweeping a Private Key. Sweeping a private key is the same as importing it, but with an extra step – all of the bitcoins belonging to the private key are sent to a new Bitcoin address on your software client. This is done via a Bitcoin transaction, so an internet connection is required to send out the transaction and complete the sweep. According to Bitcoin wiki, the probability of mistyped Bitcoin address getting accepted by the network is negligible and is around 1 in 4.3 Billion.. Case insensitive public address. On the other hand the new style Bech32 type (SegWit) Bitcoin addresses are case insensitive. However unfortunately most software clients does not support this address format yet. What is a Blockchain Private Key and Public Key (Public Address)? Private keys and Public keys are the foundation of every blockchain network. In purely cryptographic terminology, every security system requires a public key for location and a private key for private access. Applied to cryptocurrency wallets, the public key is your address ... The private key is your password and you need it to spend your Bitcoins. Bitcoin mining After you send Bitcoins using a Bitcoin wallet, this transaction information is relayed throughout the network — passes from node to node (from a server to server) until it is transmitted to all the nodes. It also contains the public and private key for each of your bitcoin addresses. Your bitcoin private key is a randomly generated string (numbers and letters), allowing bitcoins to be spent.
