Cardano is a Blockchain project, also called 3rd generation Blockchain because of its scientific philosophy, designed and developed by a team of worldwide scientists and engineers. The aim of the project is to develop a technology that is secure, flexible and scalable and can therefore be used by many millions of users. In contrast to other projects, Cardano pursues a policy that seeks to reconcile the needs of the user with those of the regulatory authorities, combining privacy with regulation. Cardano’s vision is that the project will lead to greater global financial integration for all people by providing all people with open access to fair financial services. Cardano wants to create a technological platform on which financial applications can be developed and executed. It has basically great similarities with Ethereum. Cardano is a platform such as Ethereum, EOS or NEO that enables the creation of new tokens and decentralized applications (dApps) and smart contracts. From a technical point of view, however, there are major differences which we will discuss later. The cryptocurrency of Cardano is ADA. Like any crypto currency, ADA allows the user to send assets within the Cardano network seamlessly over the Internet in a secure and fast manner. You can find the current price of ADA on our chart page.
Cardano was founded by Ethereum co-founders Charles Hoskinson and Jeremy Wood after both left the Ethereum project after a disagreement over further development. While the later Cardano founders wanted to create a commercial enterprise behind Ethereum, Vitalik Buterin’s group was able to assert itself by setting up a charitable foundation behind the project. Logically, Hoskinson and Wood founded a company, Input Output Hong Kong (IOHK), to manage Cardano’s research and development. Between September 2015 and January 2017, Cardano conducted a public ICO that raised a total of 62 million US dollars. About two thirds of all Ada tokens were sold. Cardano was officially launched on 29 September 2017. Currently the project is still in its bootstrap era (“Byron”). In the bootstrap era, when people buy or sell Ada, the transaction is automatically delegated to a pool of trusted nodes that manage the network. They do not receive block rewards in this phase of the project. IOHK is currently working on numerous improvements and features. The next phase “Shelley” is to be introduced in 2019. In this phase, the project will grow into a fully decentralized and autonomous system. This will be followed by the “Goguen” era, in which the integration of smart contracts is planned. This is followed by the “Basho” phase, which is intended to improve performance, and finally the “Voltaire” phase, which is intended to add a treasury system and a governance model (“Liquid Democracy”). The complete roadmap can be seen here.
The organization behind Cardano
As already written, Charles Hoskinson has decided to found the company IOHK in order to guarantee a coordinated and planned development of the project. IOHK is responsible for the design, development and maintenance of the Cardano platform until 2020. In addition, however, there were originally two other institutions that took care of the Cardano project: Emurgo and the Cardano Foundation, based in Switzerland. Emurgo is a Japanese company that is also currently pushing partnerships with other commercial companies and organizing Cardano’s business development. In particular, the Cardano Foundation was entrusted with administrative tasks. Otherwise the Foundation was responsible for public relations, trademark law, lobbying and cooperation with governments and regulators. In October 2018, however, there was a break between IOHK/ Emurgo and the Cardano Foundation. Among other things, Hoskinson has accused the Cardano Foundation under the direction of Michael Parsons of inaction. As a result IOHK and Emurgo decided to take over the tasks of the foundation.
Cardano: 3rd generation blockchain
Charles Hoskinson has recognized that 2nd generation blockchains still have many open problems to be successful in the long run. These are in particular scalability, interoperability and sustainability. Cardano has (partly) developed new concepts and technologies for this purpose.
In terms of scalability, there are three challenges for Cardano:
Transactions per second (TPS)
Network / Bandwidth
Transactions per second
The Transactions per Second (TPS) measure how many transactions per second can be written to a block. According to Hoskinson, however, this is only part of the problem of scaling. While Bitcoin 3-7 TPS and Ethereum 10-20 TPS create, this is far from enough to host millions of users. The solution to this problem is Cardanos Ouroboros Proof-of-Stake algorithm, which we will discuss later.
A further challenge is the network, which will also have an exponentially increasing demand for network resources with millions of users as the demand increases with the number of transactions. The demand will grow in size regions of several hundred terabytes or even exabytes. Therefore, it will be impossible to maintain a homogeneous network topology in which each node forwards each transaction and message. Not every node will have the necessary resources. To solve this problem, Cardano intends to use a technology called RINA.
Since the blockchain has to store the data forever, there will be an enormous and constantly growing amount of data to be scaled (“Data Scale”). The problem is obvious. If every node has to keep a complete copy of the entire blockchain, this will not be possible for every node from the point of view of resources. The solution is that not every node needs all data. The solution approaches therefore include in detail:
Charles Hoskinson believes that there will not be a single crypto currency to be used in the future. Therefore Cardano aims at enabling the different blockchains to communicate with each other. Cardano’s vision is to create an “Internet of blockchains” in which there is no intermediary. A solution to this problem should be for Cardano, Sidechains. The concept has been around in crypto space for quite some time. Simply put, sidechains are parallel blockchains that can communicate with the main blockchain. In addition, Cardano tries to comply with all existing compliance rules: KYC (Know Your Customer), AML (Anti Money Laundering), ATF (Anti Terrorist Financing). In order for this to work, Cardano provides metadata to each transaction.
According to Hoskinson, sustainability is the most difficult challenge. Basically, it means that continuous developments must be carried out on the system. This requires financial resources. Both a patronage and an ICO do not make sense for Hoskinson. Patronage leads to centralization, while ICOs provide short-term resources for the ecosystem, but at the same time produce a new, useless token. For this reason, Cardano is oriented towards Dash’s treasury system. Each time a block is added to the block chain, a portion of the rewards is added to the Treasury. If funds are needed for development, they can be allocated. To this end, Cardano has developed a governance model (“liquid democracy”) in which stakeholders can vote on a proposal for the distribution of funds.
Ada: Ouroboros Proof-of-Stake
Similar to Ethereum’s future proof-of-stake (PoS) “Casper”, Cardano also relies on a PoS. This means that there are no miners within the Cardano network responsible for validating transactions. A new proof-of-stake algorithm called Ouroboros was developed for Cardano. The basic difference between Ouroboros and Ethereum’s Casper or other similar algorithms is how block premium recipients (validators) are selected. The core idea of the Ouroboros Proof of Stake is that a node is selected to create a new block with a probability proportional to the total number of Ada. This means that the more Ada a stakeholder has, the more he can earn over time. In principle, each node with an Ada credit balance greater than 0 is referred to as a “stakeholder”. When a node is selected to create a new block, it is called a slot leader. The slot leader writes the transactions into a block, signs this block with his secret key and publishes the block in the network. A fundamental problem in this electoral process is randomness. To achieve this, Cardano uses a Multiparty Computation (MPC) approach in which each voter independently performs an action called coin tossing (Coin-Fllipping Protocol).
Hello, I feel I should introduce myself first. I got into Bitcoin back mid-2017. I bought in at about 1.8k if I remember correctly. I was also invested in Ethereum at this time, and got in between 60-120 (my friend sent me some at 60, but I continued to buy around 120). As many of you know. Bitcoin has been in a bear market for the past several months. And over these past several months concerns have popped into my mind in regards to the overall health and future of Bitcoin:
Bitcoin Futures were introduced into the market on December 17th, 2017. The first futures contracts expired relatively shortly after. This correlates almost exactly with the beginning of the bear-market we are in now. BTC Daily Chart
Institutions are now allowed to invest in Bitcoin. Institutions for the most part, have every reason to short Bitcoin rather than go Long. And that seems to be the case, as the money in most institutions far out-weights the money in the retail market. Making it harder for retail bulls to overpower the bears. This seems to be the case today as well.
Bitcoin has become centralized. As of today, the top 5 Bitcoin mining pools account for 67.2% of the hash power in the Bitcoin network. If you look at the top 10 mining pools, this number gets even larger at 86.6%. Meaning, Bitcoin as a network is effectively centralized. I understand that mining pools contain hundreds or thousands of miners, often independent of one another mining as a group. But correct me if I'm wrong, the workers in a pool you do NOT need to have a copy of the block chain on your miner to be apart of the pool. And if I understand more of this correctly, this means a compromise of a large network such as AntPool would lead to a large amount of the Bitcoin's hash power to be taken advantage of. Thus, leading to the very same vulnerabilities Bitcoin set out to prevent by being decentralized. Bitcoin Mining Pools Visualized
Enterprise Blockchains such as Hyperledger and Quorum have stolen away Bitcoin's potential "enterprise marketshare". Hyperledger is sponsored by The Linux Foundation and is open source. Quorum is also open source, and based directly off of Ethereum. These Blockchains do not have any sort of value or price attached to them like Bitcoin or Ethereum, and have been shown to scale much better and simpler than both Bitcoin and Ethereum. JP Morgan has used Quorum to settle bond transactions over Quorum, and further testing and implementations are being worked on now. Amazon now supports Smart Contract Templates for both Etheruem and Hyperledger. Furthermore, JP Morgan has tested "debt issuance" over Quorum, marking a huge milestone for Blockchain in our Financial Infrastructure.
None of what I mentioned above was an issue in 2013, or 2015 when we saw our previous bear markets in Bitcoin. This makes me truly believe that we're unlikely to see a bull run like we did in 2017 ever again. Not to mention the fact that Cryptocurrencies in and of themselves are more regulated than ever before, which could in turn lead to lower levels of volatility now and in the years to come. I'm sure Bitcoin will have its pops and bull runs, but nothing parabolic like we've seen in the past. Please tell me I'm wrong, because I'd rather be wrong than right in this case.
A brief history of the 2013 market peak; why some alts really do die; and what would've happened if you'd given in to FOMO
This piece is a follow-up to my earlier piece, which looked at what would’ve happened if you’d purchased alt-coins shortly after the bottom of the 2013-2015 bear market. A lot of the constructive criticism that I received was that I was too bullish on alt-coins, and that the timing was too convenient. Although it’s fair to say that I am bullish on crypto in general and alt-coins in particular (with several major caveats for both), I agree that it’s important to not just focus on historical analyses where it’s fairly clear that you could have earned money. So, today’s research question is whether you’d still be underwater if you’d bought in to the market at or near the 2013 all-time high. All information cited herein comes from the historical charts available at CoinMarketCap. TL;DR: This worst-case scenario analysis shows that $300 invested equally across 15 of the 40 coins in existence near the market’s peak in 2013 would be worth only $429.95 today—gains which are entirely attributable to Bitcoin, Litecoin, and Ripple. This is basic, but it can be dangerous to buy high. This is especially true of alt-coins, but even the top three coins in our sample saw fairly lackluster results when bought at the top of the market. Finally, nothing in this post should be taken as investment advice. This is only intended as historical analysis. Past performance does not guarantee future returns. A Brief History of the 2013 Market Peak According to CoinMarketCap, the 2013 bull market peaked on December 4, 2013, at ~$15.87 billion in market capitalization.* Thereafter, the market crashed dramatically not once, but twice. In the first crash, which occurred between December 5-8, 2013, overall market cap fell by ~39% to ~$9.66 billion. Then, after a brief recovery to ~$13.57 billion on December 10th, the market fell precipitously, to ~$5.7 billion on December 18, 2013. Thus, over the course of only two weeks, from December 4-18, 2013, the market lost ~64% of its value. Although this was by no means the end of the 2013-2015 bear market--which lasted for approximately 17 months and saw an additional decline of ~45% from the December 18, 2013 low--this was the end of the beginning. What If I Bought Crypto Right as the 2013 Market Peaked? Generally, the first rule of trading is** that you want to buy low and sell high. As a result of their fear of missing out (“FOMO”), however, many people find themselves accidentally buying high. Today, I’m going to look at what would have happened to someone who bought their crypto right as the market was peaking. Ideally, I would run this experiment from December 4, 2013, but due to the limited data available from CoinMarketCap, I’m forced to choose between November 24th, December 1st, December 8th, and December 15th. Of those dates, I have selected December 1, 2013, because it represents the worst possible scenario for which I have data. On that date, total crypto market cap, which had hit a new high of ~$15.4 billion the day before, swung wildly between a high of ~$14.83 billion and a low of ~$12.18 billion. Unfortunately, it’s unclear exactly when CoinMarketCap’s snapshot was taken. That said, it’s clear that our hypothetical FOMO trader is about to lose his shirt over the next few weeks, so let’s dive into the specifics. On December 1, 2013, there were 40 coins listed on CoinMarketCap. I won’t list them all here, but of those 40, all but 11 are still listed as active on CoinMarketCap. The truly dead (or “inactive”) coins are BBQCoin (BQC; rank 16), Devcoin (DVC; rank 19), Tickets (TIX; rank 22), Copperlark (CLR; rank 24), StableCoin (SBC; rank 25), Luckycoin (LKY—ironic, I realize; rank 31), Franko (FRK; rank 34), Bytecoin (BTE; rank 35), Junkcoin (JKE—how apt; rank 36), CraftCoin (CRC; rank 39), and Colossuscoin (COL; rank 40).*** Now, since this post is already incredibly long, instead of testing all 40 coins, let’s take a decently-sized sample of five coins each from the top, middle, and bottom of the stack, and look at what happens. For the middle, although the temptation is to take decent alts, let’s fight that and take the group with the highest failure rate: ranks 21-25. So, here’s out pool:
Top Five: Bitcoin, Litecoin, Ripple, Peercoin, and Namecoin
Middle Five: Yacoin, Tickets, Ixcoin, Copperlark, and Stablecoin (ranks 21-25)
Bottom Five: Junkcoin, Argentum, Elacoin, CraftCoin, and Colossuscoin (ranks 36-40)
Now, here are how our sample of coins has performed as of when I write this:****
Bitcoin: Up from $1,083.14 to $6,957.99—a ~6.42x increase
Litecoin: Up from $39.77 to $117.43—a ~2.95x increase
Ripple: Up from $0.047034 to $0.527721—an ~11.22x increase
Peercoin: Down from $7.58 to $1.62—a ~78.6% loss
Namecoin: Down from $9.94 to $1.52—an 84.7% loss
So, if our hypothetical FOMO trader had invested $100 in our top-five sample near the 2013 peak, it would currently be worth $411.80 (the profitable coins) + $3.06 (PPC) + $4.27 (NMC) = $419.13—a 4.19x increase. Now for the two coins in the middle five that didn’t completely die:
Yacoin: Down from $0.311704 to $0.001025—a ~99.7% loss (Note: Since a $20 investment would only be worth a little over six cents, I’m calling this a total loss)
Ixcoin: Down from $0.146275 to 0.111126—a ~24% loss
So, if our hypothetical FOMO trader had invested $100 in our middle-five sample near the 2013 peak, it would currently be worth ~$15.19—an ~84.8% loss. Finally, here are the two coins from the bottom five that didn’t completely die:
Elacoin: Down from $10.95 to $0.212289—a ~98% loss (Note: since this is only worth about $0.39, I’m calling this a total loss)
Argentum: Down from $0.793038 to $0.117466—an ~85.2% loss.
So, excluding everything buy Argentum, if our hypothetical FOMO trader had invested $100 in our bottom-five sample near the 2013 peak, it would currently be worth ~$2.96—a ~97% loss. Putting it all together, $300 invested in this sample of 15 coins as close to the peak of the 2013 market as the data will let me get, would be worth $429.95—a disappointing, but not-unexpected ~30.2% increase over five years. That said, I’m honestly somewhat amazed our FOMO trader made anything at all on this basket of coins, considering how many of them failed. In any case, all of his gains came from the top-three coins from 2013: Bitcoin, Litecoin, and Ripple. Conclusions What’s the lesson here, what’s the takeaway?***** Most importantly, I think the above analysis shows that it can be very dangerous to buy alt-coins when the market is at or near an all-time high—a conclusion that appears to be true regardless of where the alt is positioned in the market. That said, there are a few caveats: (1) this sample was intentionally bad, in order to reflect a worst-case scenario; (2) even buying the top-three coins at the all-time high didn’t net our FOMO trader particularly large gains when compared to someone who bought these same coins after the crash. Therefore, I think that the most important lesson here is not to buy high in the first place. Investing solely because of FOMO will probably cause you to lose money, unless you have invested equally in a broad range of cryptocurrencies, like the trader in our hypothetical. Even then, however, our FOMO trader probably would have done better investing in an S&P Index fund over the same period. Endnotes *This is a correction to my earlier piece, in which I stated that the cryptocurrency market peaked on November 30, 2013, at a total market capitalization of ~$15.2 billion. I made this error due to having failed to narrow the date range of the chart so I could properly zoon in. That said, the exact details of the market peak don’t affect the conclusions from my last piece, which considered trades made after the market had bottomed out. ** …you do not talk about trading. Wait, that’s the wrong rulebook. *** Since I already typed it out, here’s the list of remaining active coins, in descending order: Bitcoin (BTC), Litecoin (LTC), Ripple (XRP), Peercoin (PPC), Namecoin (NMC), Megacoin (MEC), Feathercoin (FTC), WorldCoin (WDC), Primecoin (XPM), Freicoin (FRC), Novacoin (NVC), Zetacoin (ZET), Infinitecoin (IFC), Terracoin (TRC), Crypto Bullion (CBX), Anoncoin (ANC), Digitalcoin (DGC), GoldCoin (GLD), Yacoin (YAC), Ixcoin (IXC), Fastcoin (FST), BitBar (BTB), Mincoin (MNC), Tagcoin (TAG), FlorinCoin (FLO), I0Coin (I0C), Phoenixcoin (PXC), Argentum (ARG), Elacoin (ELC) **** I know that we could have sold them sooner, and probably for more money, but let’s just assume that our hypothetical FOMO trader was a founding member of the #hodlgang. ;-) ***** Don’t mess with Maui when he’s on a breakaway! You’re welcome. ;-) Disclosures: I have previous held Litecoin, and currently hold approximately $140 of Ripple. I do not believe this influenced my analysis in any way. I have never bought or held any of the other coins discussed in this analysis. Edits: Formatting, typos, minor clarifications.
I just finished writing my most recent letter to investors and thought I would share it with Reddit as well. "Welcome to another edition of the Boss Crypto “Letter To Investors” series. Thank you for taking the time out of your busy schedule for us. The last week has been relatively uneventful, as I expect the next part of the cycle to be so I took some time to write an analysis of longer-term Bitcoin trends. The Markets I believe that it is important to talk a little bit about where we are right now. My opinion is that we are in the depression stage of the cycle. A lot of altcoins are down over 90% and that is a big number. Do you know how far Amazon stock dropped in the tech bubble from January 2000 — September 2001 (20 months later)? It dropped 95% — Sound familiar? During this time nobody wanted to touch it, the market could only think of negative reasons why the price would go down forever. Investors were pessimistic, and nobody had the courage to act. Some companies died, forever, but what came next was the re-birth of something 100x bigger. It went from a tech bubble to the tech revolution. And you wouldn’t be here if, at some stage, you didn’t believe in the blockchain revolution. Now, we don’t know now what companies will be the next blockchain Amazons, but we are looking for them every day. And we will find them. While we move through this stage of the cycle, capital will be tight, and we need to be even more prudent with our investments. Keeping portions in cash, taking profits earlier than usual or making long term investments that you intend to hold for long periods of time. And even with these long term investments, you should have exit rules, both profit — and loss. Price cycles around a trend. This is something we all know. Using trends as forecasts for the future price of an asset are simply extrapolations of the past into the future and there is no guarantee that the previous trend will repeat exactly. I believe they offer a good amount of insight into the flow of price, yet would not trust it, for example, to predict the exact dollar value of Bitcoin in 2021. The below is a simple breakdown of the past trends as they were before the bulls took over and blew the price to crazy highs. This phenomenon is in no way just related to cryptocurrency trading and investing. It happens in every market. Why? Because humans are involved in every market. https://preview.redd.it/e2bbthvxdad21.png?width=2684&format=png&auto=webp&s=ea12dc6d63e1d1b13b90da69001cbe7a23c6a1f3 Firstly You can see the % retrace marked in blue. And you can see the horizontal green box, which was the depression stage at the end of the 2015 bear market, duplicated to today's market. Secondly You can see there are two main lines that I am looking at. The highest of the two was the 2012–2013 bullish accumulation period before the major breakout at the start of 2013 and the second is the bullish accumulation period from the end of 2015 to the start of 2017 before the major breakout. As you can see, the second accumulation trend was at a slower incline than the first, and I believe that was caused by a much larger collection of money in the pool. From this data, I would then make the assumption that the next bullish accumulation trend, after the depression period, will also be slower than the 2015–2017 trend, yet might catch up at the peak of the breakout. Thirdly You can see similarities in volume. I wanted to talk about this because the volume charts look similar across most exchanges that were trading Bitcoin during the last bear market. The amount of volume in both the bull market and bear markets of 2017 and 2018 was lower than the volume of the 2014–2015 markets. However, the shape is the same:
A build-up of Euphoria
Unknown in 2019, and in 2015 we saw more uncertainty, or as I am referring to it: Depression.
Conclusion There is no way that we can know for certain what is to come, and it is unlikely to repeat exactly however this picture does show us a clear picture on the past market performance in all times, across all emotions. It is a complete picture. The depression cycle is always (not just in cryptocurrency) the most important to be vigilant to new investments. While a lot of old projects will succeed, a lot that came through in the ICO boom are dying, new ones will be there to take their place. To your 2019, Boss Cole, Trader — BossCrypto "
On May 6th, 2017, Bitcoin hit an all-time high in transactions processed on the network in a single day: it moved 375,000 transactions which accounted for a nominal output of about $2.5b. Average fees on the Bitcoin network had climbed over a dollar for the first time a couple days prior. And they kept climbing: by early June average fees hit an eye-watering $5.66. This was quite unprecedented. In the three-year period from Jan. 1 2014 to Jan. 1 2017, per-transaction fees had never exceeded 31 cents on a weekly average. And the hits kept coming. Before 2017 was over, average fees would top out at $48 on a weekly basis. When the crypto-recession set in, transaction count collapsed and fees crept back below $1. During the most feverish days of the Bitcoin run-up, when normal users found themselves with balances that would cost more to send than they were worth, cries for batching — the aggregation of many outputs into a single transaction — grew louder than ever. David Harding had written a blog post on the cost-savings of batching at the end of August and it was reposted to the Bitcoin subreddit on a daily basis. The idea was simple: for entities sending many transactions at once, clustering outputs into a single transaction was more space- (and cost-) efficient, because each transaction has a fixed data overhead. David found that if you combined 10 payments into one transaction, rather than sending them individually, you could save 75% of the block space. Essentially, batching is one way to pack as many transactions as possible into the finite block space available on Bitcoin. When fees started climbing in mid-2017, users began to scrutinize the behavior of heavy users of the Bitcoin blockchain, to determine whether they were using block space efficiently. By and large, they were not — and an informal lobbying campaign began, in which these major users — principally exchanges — were asked to start batching transactions and be good stewards of the scarce block space at their disposal. Some exchanges had been batching for years, others relented and implemented it. The question faded from view after Bitcoin’s price collapsed in Q1 2018 from roughly $19,000 to $6000, and transaction load — and hence average fee — dropped off. But we remained curious. A common refrain, during the collapse in on-chain usage, was that transaction count was an obfuscated method of apprehending actual usage. The idea was that transactions could encode an arbitrarily large (within reason) number of payments, and so if batching had become more and more prevalent, those payments were still occurring, just under a regime of fewer transactions. “hmmm” Some sites popped up to report outputs and payments per day rather than transactions, seemingly bristling at the coverage of declining transaction count. However, no one conducted an analysis of the changing relationship between transaction count and outputs or payments. We took it upon ourselves to find out. Table Of Contents: Introduction to batching A timeline Analysis Conclusion Bonus content: UTXO consolidation
Introduction to batching
Bitcoin uses a UTXO model, which stands for Unspent Transaction Output. In comparison, Ripple and Ethereum use an account/balance model. In bitcoin, a user has no balances, only UTXOs that they control. If they want to transfer money to someone else, their wallet selects one or more UTXOs as inputs that in sum need to add up to the amount they want to transfer. The desired amount then goes to the recipient, which is called the output, and the difference goes back to the sender, which is called change output. Each output can carry a virtually unlimited amount of value in the form of satoshis. A satoshi is a unit representing a one-hundred-millionth of a Bitcoin. This is very similar to a physical wallet full of different denominations of bills. If you’re buying a snack for $2.50 and only have a $5, you don’t hand the cashier half of your 5 dollar bill — you give him the 5 and receive some change instead. Unknown to some, there is no hardcoded limit to the number of transactions that can fit in a block. Instead, each transaction has a certain size in megabytes and constitutes an economic incentive for miners to include it in their block. Because miners have limited space of 2 MB to sell to transactors, larger transactions (in size, not bitcoin!) will need to pay higher fees to be included. Additionally, each transaction can have a virtually unlimited number of inputs or outputs — the record stands at transactions with 20,000 inputs and 13,107 outputs. So each transaction has at least one input and at one output, but often more, as well as some additional boilerplate stuff. Most of that space is taken up by the input (often 60% or more, because of the signature that proves they really belong to the sender), while the output(s) account for 15–30%. In order to keep transactions as small as possible and save fees, Bitcoin users have two major choices: Use as few inputs as possible. In order to minimize inputs, you can periodically send your smaller UTXOs to yourself in times when fees are very low, getting one large UTXO back. That is called UTXO consolidation or consolidating your inputs. Users who frequently make transfers (especially within the same block) can include an almost unlimited amount of outputs (to different people!) in the same transaction. That is called transaction batching. A typical single output transaction takes up 230 bytes, while a two output transaction only takes up 260 bytes, instead of 460 if you were to send them individually. This is something that many casual commentators overlook when comparing Bitcoin with other payment systems — a Bitcoin transaction can aggregate thousands of individual economic transfers! It’s important to recognize this, as it is the source of a great deal of misunderstanding and mistaken analysis. We’ve never encountered a common definition of a batched transaction — so for the purposes of this study we define it in the loosest possible sense: a transaction with three or more outputs. Commonly, batching is understood as an activity undertaken primarily by mining pools or exchanges who can trade off immediacy for efficiency. It is rare that a normal bitcoin user would have cause to batch, and indeed most wallets make it difficult to impossible to construct batched transactions. For everyday purposes, normal bitcoiners will likely not go to the additional effort of batching transactions. We set the threshold at three for simplicity’s sake — a normal unbatched transaction will have one transactional output and one change output — but the typical major batched transaction from an exchange will have dozens if not hundreds of outputs. For this reason we are careful to provide data on various different batch sizes, so we could determine the prevalence of three-output transactions and colossal, 100-output ones. We find it helpful to think of a Bitcoin transaction as a mail truck full of boxes. Each truck (transaction) contains boxes (outputs), each of contains some number of letters (satoshis). So when you’re looking at transaction count as a measure of the performance and economic throughput of the Bitcoin network, it’s a bit like counting mail trucks to discern how many letters are being sent on a given day, even though the number of letters can vary wildly. The truck analogy also makes it clear why many see Bitcoin as a settlement layer in the future — just as mail trucks aren’t dispatched until they’re full, some envision that the same will ultimately be the case for Bitcoin. Batching
So what actually happened in the last six months? Let’s look at some data. Daily transactions on the Bitcoin network rose steadily until about May 2017, when average fees hit about $4. This precipitated the first collapse in usage. Then began a series of feedback loops over the next six months in which transaction load grew, fees grew to match, and transactions dropped off. This cycle repeated itself five times over the latter half of 2017. more like this on coinmetrics.io The solid red line in the above chart is fees in BTC terms (not USD) and the shaded red area is daily transaction count. You can see the cycle of transaction load precipitating higher fees which in turn cause a reduction in usage. It repeats itself five or six times before the detente in spring 2018. The most notable period was the December-January fee crisis, but fees were actually fairly typical in BTC terms — the rising BTC price in USD however meant that USD fees hit extreme figures. In mid-November when fees hit double digits in USD terms, users began a concerted campaign to convince exchanges to be better stewards of block space. Both Segwit and batching were held up as meaningful approaches to maximize the compression of Bitcoin transactions into the finite block space available. Data on when exchanges began batching is sparse, but we collected information where it was available into a chart summarizing when exchanges began batching. Batching adoption at selected exchanges We’re ignoring Segwit adoption by exchanges in this analysis; as far as batching is concerned, the campaign to get exchanges to batch appears to have persuaded Bitfinex, Binance, and Shapeshift to batch. Coinbase/GDAX have stated their intention to begin batching, although they haven’t managed to integrate it yet. As far as we can tell, Gemini hasn’t mentioned batching, although we have some mixed evidence that they may have begun recently. If you know about the status of batching on Gemini or other major exchanges please get in touch. So some exchanges have been batching all along, and some have never bothered at all. Did the subset of exchanges who flipped the switch materially affect the prevalence of batched transactions? Let’s find out.
3.1 How common is batching? We measured the prevalence of batching in three different ways, by transaction count, by output value and by output count. The tl;dr. Batching accounts for roughly 12% of all transactions, 40% of all outputs, and 30–60% of all raw BTC output value. Not bad. 3.2 Have batched transactions become more common over time? From the chart in 3.1, we can already see a small, but steady uptrend in all three metrics, but we want to dig a little deeper. So we first looked at the relationship of payments (all outputs that actually pay someone, so total outputs minus change outputs) and transactions. More at transactionfee.info/charts The first thing that becomes obvious is that the popular narrative — that the drop in transactions was caused by an increase in batching — is not the case; payments dropped by roughly the same proportion as well. Dividing payment count by transaction count gives us some insight into the relationship between the two. In our analysis we want to zoom into the time frame between November 2017 and today, and we can see that payments per transactions have actually been rallying, from 1.5 payments per transaction in early 2017 to almost two today. 3.3 What are popular batch sizes? In this next part, we will look at batch sizes to see which are most popular. To determine which transactions were batched, we downloaded a dataset of all transactions on the Bitcoin network between November 2017 and May 2018from Blockchair. We picked that period because the fee crisis really got started in mid-November, and with it, the demands for exchanges to batch. So we wanted to capture the effect of exchanges starting to batch. Naturally a bigger sample would have been more instructive, but we were constrained in our resources, so we began with the six month sample. We grouped transactions into “batched” and “unbatched” groups with batched transactions being those with three or more outputs. We then divided batched transactions into roughly equal groups on the basis of how much total output in BTC they had accounted for in the six-month period. We didn’t select the batch sizes manually — we picked batch sizes that would split the sample into equal parts on the basis of transaction value. Here’s what we ended up with: All of the batch buckets have just about the same fraction of total BTC output over the period, but they account for radically different transaction and output counts over the period. Notice that there were only 183,108 “extra large” batches (with 41 or more outputs) in the six-month period, but between them there were 23m outputs and 30m BTC worth of value transmitted. Note that output value in this context refers to the raw or unadjusted figure — it would have been prohibitively difficult for us to adjust output for change or mixers, so we’re using the “naive” estimate. Let’s look at how many transactions various batch sizes accounted for in the sample period: Batched transactions steadily increased relative to unbatched ones, although the biggest fraction is the small batch with between 3 and 5 outputs. The story for output counts is a bit more illuminating. Even though batched transactions are a relatively small fraction of overall transaction count, they contain a meaningful number of overall outputs. Let’s see how it breaks down: Lastly, let’s look at output value. Here we see that batched transactions represent a significant fraction of value transmitted on Bitcoin. As we can see, even though batched transactions make up an average of only 12% of all transactions, they move between 30%-60% of all Bitcoins, at peak times even 70%. We think this is quite remarkable. Keep in mind, however that the ‘total output’ figure has not been altered to account for change outputs, mixers, or self-churn; that is, it is the raw and unadjusted figure. The total output value is therefore not an ideal approximation of economic volume on the Bitcoin network. 3.4 Has transaction count become an unreliable measure of Bitcoin’s usage because of batching? Yes. We strongly encourage any analysts, investors, journalists, and developers to look past mere transaction count from now on. The default measure of Bitcoin’s performance should be “payments per day” rather than transaction count. This also makes Bitcoin more comparable with other UTXO chains. They generally have significantly variable payments-per-transaction ratios, so just using payments standardizes that. (Stay tuned: Coinmetrics will be rolling out tools to facilitate this very soon.) More generally, we think that the economic value transmitted on the network is its most fundamental characteristic. Both the naive and the adjusted figures deserve to be considered. Adjusting raw output value is still more art than science, and best practices are still being developed. Again, Coinmetrics is actively developing open-source tools to make these adjustments available.
We started by revisiting the past year in Bitcoin and showed that while the mempool was congested, the community started looking for ways to use the blockspace more efficiently. Attention quickly fell on batching, the practice of combining multiple outputs into a single transaction, for heavy users. We showed how batching works on a technical level and when different exchanges started implementing the technique. Today, around 12% of all transactions on the Bitcoin network are batched, and these account for about 40% of all outputs and between 30–60% of all transactional value. The fact such that a small set of transactions carries so much economic weight makes us hopeful that Bitcoin still has a lot of room to scale on the base layer, especially if usage trends continue. Lastly, it’s worth noting that the increase in batching on the Bitcoin network may not be entirely due to deliberate action by exchanges, but rather a function of its recessionary behavior in the last few months. Since batching is generally done by large industrial players like exchanges, mixers, payment processors, and mining pools, and unbatched transactions are generally made by normal individuals, the batched/unbatched ratio is also a strong proxy for how much average users are using Bitcoin. Since the collapse in price, it is quite possible that individual usage of Bitcoin decreased while “industrial” usage remained strong. This is speculation, but one explanation for what happened. Alternatively, the industrial players appear to be taking their role as stewards of the scarce block space more seriously. This is a significant boon to the network, and a nontrivial development in its history. If a culture of parsimony can be encouraged, Bitcoin will be able to compress more data into its block space and everyday users will continue to be able to run nodes for the foreseeable future. We view this as a very positive development. Members of the Bitcoin community that lobbied exchanges to add support for Segwit and batching should be proud of themselves.
Bonus content: UTXO consolidation
Remember that we said that a second way to systematically save transaction fees in the Bitcoin network was to consolidate your UTXOs when fees were low? Looking at the relationship between input count and output count allows us to spot such consolidation phases quite well. Typically, inputs and outputs move together. When the network is stressed, they decouple. If you look at the above chart carefully, you’ll notice that when transactions are elevated (and block space is at a premium), outputs outpace inputs — look at the gaps in May and December 2017. However, prolonged activity always results in fragmented UTXO sets and wallets full of dust, which need to be consolidated. For this, users often wait until pressure on the network has decreased and fees are lower. Thus, after transactions decrease, inputs become more common than outputs. You can see this clearly in February/March 2017. Here we’ve taken the ratio of inputs to outputs (which have been smoothed on a trailing 7 day basis). When the ratio is higher, there are more inputs than outputs on that day, and vice versa. You can clearly see the spam attack in summer 2015 in which thousands (possibly millions) of outputs were created and then consolidated. Once the ratio spikes upwards, that’s consolidation. The spike in February 2018 after the six weeks of high fees in December 2017 was the most pronounced sigh of relief in Bitcoin’s history; the largest ever departure from the in/out ratio norm. There were a huge number of UTXOs to be consolidated. It’s also interesting to note where inputs and outputs cluster. Here we have histograms of transactions with large numbers of inputs or outputs. Unsurprisingly, round numbers are common which shows that exchanges don’t publish a transaction every, say, two minutes, but instead wait for 100 or 200 outputs to queue up and then publish their transaction. Curiously, 200-input transactions were more popular than 100-input transactions in the period. We ran into more curiosities when researching this piece, but we’ll leave those for another time. Future work on batching might focus on: Determining batched transactions as a portion of (adjusted) economic rather than raw volume Looking at the behavior of specific exchanges with regards to batching Investigating how much space and fees could be saved if major exchanges were batching transactions Lastly, we encourage everyone to run their transactions through the service at transactionfee.info to assess the efficiency of their transactions and determine whether exchanges are being good stewards of the block space. Update 31.05.2018 Antoine Le Calvez has created a series of live-updated charts to track batching and batch sizes, which you can find here. We’d like to thank 0xB10C for their generous assistance with datasets and advice, the people at Blockchair for providing the core datasets, and David A. Harding for writing the initial piece and answering our questions.
/r/Monero - Newcomers Please Read. Everything You Need To Know.
What is Monero (XMR)? Monero is a secure, private, untraceable (crypto-)currency. It is open-source and freely available to all. Don't believe us? Click here. Monero is a tool that people can actually use. It makes receiving payments hassle-free, since merchants and individuals no longer need to fear the source of funds they are accepting. With transparent systems like Bitcoin, Ethereum, Verge, or Dash, these people need to hope (or spend substantial resources verifying) the sender did not use the funds illicitly. Furthermore, merchants do not want all their vendors known, and individually do not want everyone to know how much they are spending. If I spend more than I should at Newegg (store), that's my own business. Monero is different because every transaction is always private. There is no way for pools and exchanges to opt out of sending private transactions. Thus, Monero's anonymity set far exceeds any other coin's anonymity set. Over 86,000 transactions in the past month of August, 2017 hid the sender and receiver, and about 99.95% of them also hid the amount (will increase to 100% of all new transactions in September)! There is no suspicion in using a private transaction, since all transactions are private. A single transaction does not stick out.* This privacy is afforded with the best technology. I implore you to take a few minutes to learn about the four main technologies that Monero uses to provide privacy:
Ring signatures hide where the money comes from. Spent inputs in a transaction are hidden among several others that also appear to be spent. Thus, no one knows which source of money is actually being spent. Think of inputs as individual dollars or euros. View a video about this topic here. Note: this is NOT the same as mixing.
RingCT hides the amount. Instead of spending a known value of an input, you can cryptographically commit to a certain value without revealing what the value actually is. This is a very complicated topic, so please view this video for more information.
Kovri is a work-in-progress tool to hide the transaction broadcast. Kovri will make it easy for users to hide their IP address when telling the network that they would like to make a transaction. Kovri will work with other cryptocurrencies and other projects through a common API, and Kovri can be used in a way to hide that you are using Monero at all. Kovri adds additional layers of network security for miners and pools, and it allows for the highest level of censorship resistance possible. A video for this project is available, and you can also check out the Kovri website. In the meantime, there are several guides to using Monero with Tor that work today, including an unofficial Tails build.
Stealth addresses hide where the money goes to. Instead of sending money to a specific address directly, certain outputs are allocated for addresses, but outside observers do not know which addresses these belong to. Even if ring signatures were compromised for some reason, then people would still not know the sending address in a transaction thanks to stealth addresses. View a video about this topic here.
There are several other things that make Monero great! It has a smooth tail emission, dynamic blocks and fees, and an accessible Proof of Work (mining) algorithm. *You can optionally choose a very large, unusual ringsize to make the transaction stick out. This is not recommended, and normal users who leave the ringsize at the default setting will not experience any issues. Also, it's possible for a user to manually add identifying information to the tx_extra field, which is something that a user must seriously go out of their way to do. Now you know Monero (XMR) has the best technology. What else makes Monero (XMR) different than other cryptocurrencies?
Fungible: Every Monero remains equal and identical to any other Monero. It is the property of a crypto asset whose units/value are capable of mutual substitution no matter what historical transactions occurred in the past.
Value-Growth: Monero has a proven chart record of growth and will continue to grow. Don't believe us? August 2015: $0.45, August 2016: $12, August 2017: $100. Growing really fast right? The difference is that it is growing because it's being used appropriately for it's technology and the demand keeps increasing. Swiss banks and offshores management organizations are starting to move from physical assets to Monero (XMR). Monero is dedicated to continue growing.
Development-Growth: Monero has the best team. Over 270 contributors have brought Monero to where it is today. The vast majority of people donate their time to help Monero, but a few get paid through the Forum Funding System (FFS). This is how Monero can be a strong project despite not taking a portion of the block rewards or launching with a premine.
P.S. Want a quick-start, simple your-grandma-could-do-it guide?Here's a great one! Am I a bad person to consider using this? No, Monero is freedom money. You can do whatever you want with it, whenever you want, where ever you want. We make it clear that you should own your wealth 100%. What you do with it, is none of our concern. Where does the word Monero come from? The word Monero comes from the language Esperanto. Monero means coin oand currency. The plural way of saying Monero in Esperanto and in our cryptocurrency is Moneroj.
Is there a lightweight wallet for Monero? Not yet, but you can use the official GUI with a remote node.
Are there any other ways to store Monero (XMR)? Yes, there are many mobile wallets out there that allow you to store Monero (XMR). We do not recommend them, because they are not official releases of Monero. If you do decide to use other wallets, please make sure to do your research first before storing any Moneroj in the wallet. Anything used for Monero outside of official releases, will be used at your own risk. Some may be used for scamming purposes. If you still decide to take the risk; do not use them for large amounts. Also keep in mind that there is a high chance that Monero support will not be able to help you if you bump into any problems from applications outside of official releases. Why should you not use non-official wallets? Well would you buy a house and give your only key you have to the buildemanagement and wait for him/her to open the door to the house you supposedly own? No. Same goes with cryptocurrencies. You should always have possession of your private keys, and your Moneroj. Most non-official releases own your private keys, therefore you do not own the Moneroj.
How can I setup a local wallet while running node with little bandwidth? You can use GUI, as a remote node as it uses very little bandwidth. Go to settings tab and change: "localhost:18089" to "node.moneroworld.com:18089". If you are still having problems, then just use our Monero Web-Wallet.
My vendor only accepts bitcoin but I only have Monero, and I know bitcoin is not private/anonymous. What should I do? Use XMR.TO, but you should also educate them about bitcoins lack of privacy. Tell them to visit this post.
How long does it take to sync to the blockchain? It can take from a few hours (using SSD drive) or even 24 hours, depending on hard drive and connection speed.
List of scams: (Always do a background check / research for anything outside of official releases.)

How can I participate in the Monero community? We welcome everyone to join us and help out. Check the "Community Info" section on our subreddit for our website, forum, stack exchange, github, twitter, and facebook. Anyway, we hope you stick around beyond the hype. Monero has a lot going for it, and we hope you agree! We really need your help, since this project is entirely driven by the community!
There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition). That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)
EDIT 2017-01-09: Wallets WITHOUT Clients
Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin: Multi-Coin Wallet GeneratorNow supporting 129 currencies!Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos. Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.
EDIT 2016-11-23: SEMANTICS about MINING! :P
Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...
MINING IS DEAD!
MINING DOGECOIN IS UNPROFITABLE!
Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time. Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/ Oh, and most important:
READ BEFORE YOU POST!
At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess. OK, first things first.
A client is a piece of software you keep on your computer which holds one or more wallets. Here are the current client versions. If you're using an older client please upgrade to the newest version prior to sending/receiving coins. Backup! Backup! Backup your wallet.dat file or private key so you can import them into the latest version of the client.
Be warned that unless you’re running Core (aka QT), you could have issues with wallets containing lots of UTXOs (Unspent Transaction Outputs - Where your coins REALLY live). Go read the ELI5 below, and keep a close eye on your transaction counts. If you DO run Core, realise that all full clients, regardless of the coin, require a copy of the blockchain and must keep it up to date. This will cost you time, storage space and bandwidth. You can save a little by downloading the bootstrap file though. I haven’t checked how recent this one is, so let me know if you find a more current version.
OK, so next, grab this wallet generator. Even if you plan on running a client(s). Because a) it does many, many cryptocurrencies, and b) you WILL need wallets at some stage over and above what you keep in your clients. Just be sure to run it locally (and offline if you’re truly paranoid).
Oh, and here’s a simple way to keep track of all your wallets using HTML. You can grab the source and modify it, then upload it wherever you need to suit your needs. You will also want a separate file with your private keys, but don’t upload that one anywhere, because if you lose your keys or someone else gets access to them, you will lose your coins.
Next, be aware that there are online wallets available. While any wallet you don’t own the keys to isn’t actually yours, and therefore isn’t safe, the following are safer than most. Dogetipbot of course is used daily by shibes on Reddit. Block.io uses multisig and gives you Doge, BTC and LTC wallets as well as testnets, and Dogechain gives you your private keys (and also offers a wallet sweeping service).
Exchanges also offer wallets, of course. Not that you should use them to store your hard-earned coins, because they can and do get hacked with monotonous regularity. But at some stage you’re going to want to trade, or hold a few uncommon coins. You could do worse than these three:
And then there’s the obligatory question of mining. Put simply, mining is for all intents and purposes dead, and has been for a long time now. The costs are greater than any possible returns. But, if you insist on doing it anyway, maybe because you inherited a miner, you can earn about 0.01 LTC/day per MH/s merge-mining at Litecoinpool. That’s about 4 cents. :(
Shibes sometimes complain that the devs are not as active in /dogecoin as they used to be. You can find them on IRC, slack or their very own sub if you need them though. Or poke sporklin, who can often help.
You can of course ask any questions here, or post them in the sub. However, do try searching first, because I guarantee every possible question has been asked many times before. And you should also subscribe and hang out in /dogeducation occasionally. There’s much awesomeness there.
From peoplma I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere. Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge. And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core. From pts2002 Finally a proper sticky post! Here's some other stuff you could add: zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day shapeshift.io exchange - My favourite exchange, quick and easy. No registration required! Also, you should add some blockchain explorers! chain.so - Support for bitcoin, litecoin and doge. dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?) EDIT: Here's another thing I found! preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!
Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures. dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd. Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome. Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules. Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd. dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets. Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue) Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing. Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged. Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing. A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning. Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store. iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.". Nearest goal is to make the app crash free. Both mobile apps received new design themes. dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.". Up next is supporting dynamic page widths site wide and deploying new visual blocks home page. Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One). Ticket splitting: updated to use Go modules and added simnet support, several fixes. docs: beginner's guide overhaul, multiple fixes and cleanups. decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet. @Richard-Red is building a curated list of Decred-related GitHub repositories. Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus! Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)
Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate. Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply. Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.
Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example. A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1. Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks. Three more wallets integrated Decred in September:
Atomic desktop wallet added Decred in version 0.1.31. The team answered many questions on Reddit.
AnyBit wallet added Decred. It features built-in price and news tracking. Notably, the source code is open for their Android and iOS wallets.
Coboadded Decred support into their Android and iOS wallets.
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets. Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.
The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.
Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed. Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate.

Meetup at Binzantin Cafe in Taipei, Taiwan. @morphymore: "There were 20-ish attendees, and about half of them have joined the Chinese FB group. Most of them don't hear about Decred before, but have expressed the interest in learning more about it after the event. Overall, it's a good exposure for Decred in the Taiwan community.". A report with photos was posted on Facebook, more photos are here and here.

August issue of Decred Journal was translated to Russian. Many thanks to @DZ! Rency cryptocurrency ratings published a report on Decred and incorporated a lot of feedback from the community on Reddit. September issue of Chinese CCID ratings was published (snapshot), Decred is still at the bottom. Videos:

Decentralized autonomous funding of blockchain projects by @Richard-Red (medium, discussion on decred and dashpay)
The trouble with infrastructure, "thin" protocols in particular, is that someone has to build them at a cost. e.g. LN takes a ton of work, doesn't necessarily generate value itself, but it magnifies the value of BTC or whatever coin that uses it. I see the DEX in a similar light - whoever creates it is not going to make a bunch of money from it, but it will magnify the value of the underlying asset(s) that end up having a deep order book on the DEX. (@jy-p in #dex)
Twitter: why decentralized governance and funding are necessary for network survival and the power of controlling the narrative; learning about governance more broadly by watching its evolution in cryptocurrency space, importance of community consensus and communications infrastructure. Reddit: yet another strong pitch by @solar; question about buyer protections; dcrtime internals; a proposal to sponsor hoodies in the University of Cape Town; Lightning Network support for altcoins. Chats: skills to operate a stakepool; voting details: 2 of 3 votes can approve a block, what votes really approve are regular tx, etc; scriptless script atomic swaps using Schnorr adaptor signatures; dev dashboard, choosing work, people do best when working on what interests them most; opportunities for governments and enterprise for anchoring legal data to blockchain; terminology: DAO vs DAE; human-friendly payments, sharing xpub vs payment protocols; funding btcsuite development; Politeia vote types: approval vote, sentiment vote and a defund vote, also linking proposals and financial statements; algo trading and programming languages (yes, on #trading!); alternative implementation, C/C++/Go/Rust; HFTs, algo trading, fake volume and slippage; offline wallets, usb/write-only media/optical scanners vs auditing traffic between dcrd and dcrwallet; Proof of Activity did not inspire Decred but spurred Decred to get moving, Wikipedia page hurdles; how stakeholders could veto blocks; how many votes are needed to approve a proposal; why Decrediton uses Electron; CVE-2018-17144 and over-dependence on single Bitcoin implementation, btcsuite, fuzz testing; tracking proposal progress after voting and funding; why the wallet does not store the seed at all; power connectors, electricity, wiring and fire safety; reasonable spendings from project fund; ways to measure sync progress better than block height; using Politeia without email address; concurrency in Go, locks vs channels. #support is not often mentioned, but it must be noted that every day on this channel people get high quality support. (@bee: To my surprise, even those poor souls running Windows 10. My greatest respect to the support team!)
In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August. As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx) Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.
ASIC for Lyra2REv2 was spotted on the web. Vertcoin team is preparing a new PoW algorithm. This would be the 3rd fork after two previous forks to change the algorithm in 2014 and 2015. A report titled The Positive Externalities of Bitcoin Mining discusses the benefits of PoW mining that are often overlooked by the critics of its energy use. A Brief Study of Cryptonetwork Forks by Alex Evans of Placeholder studies the behavior of users, developers and miners after the fork, and makes the cases that it is hard for child chains to attract users and developers from their parent chains. New research on private atomic swaps: the paper "Anonymous Atomic Swaps Using Homomorphic Hashing" attempts to break the public link between two transactions. (bitcointalk, decred) On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange. Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.". Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred) The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights. A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.
