Hi Bitcoiners! I’m back with the fifteenth monthly Bitcoin news recap. For those unfamiliar, each day I pick out the most popularelevant/interesting stories in Bitcoin and save them. At the end of the month I release them in one batch, to give you a quick (but not necessarily the best) overview of what happened in bitcoin over the past month. And a lot has happened. It's easy to forget with so much focus on the price. Take a moment and scroll through the list below. You'll find an incredibly eventful month. You can see recaps of the previous months on Bitcoinsnippets.com A recap of Bitcoin in March 2018
$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC price impact discussed
Preamble: it seems that my post was censored and removed on bitcoin... from now I will only publish my articles on btc and crosspost it. Freedom and freespeech matter to me. -- This is the 4th post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The facts that part of this funds (>13%) have been transferred in the past month to Bitfinex, Binance and Bitmex exchanges is discussed here.
The origin of the bitcoins was originally discussed here.
A deep-dive into the wallet activity was discussed here.
Today I am writing a short update to discuss the origin of the funds and some events that could be related both to this wallet and yesterday's price crash. Wallet's origin This question has been discussed a lot by the crypto community in the past year. Here is a summary of the most probable hypothesis for the 1933p wallet's origin:
Wizsec, a prominent Bitcoin security expert, seems to be pretty sure that the wallet belongs to a MtGox hodler and early investor, who is not a DPR or a SilkRoad user, per his Twitter post: https://twitter.com/wizsecurity/status/1037030003068653569 Finally, Wizsec and I agree that this wallet is not CSW`'s wallet despite it is mentioned in several court documents. Wizsec spent a lot of time debunking CSW's ownership claims earlier this year: https://twitter.com/wizsecurity/status/968337084837781504 What do you think about this wallet origin? ` BTC price crash Also, I wanted to report some events that could be related to this 1933p wallet activity:
$100M USDT were transferred (reported by u/whalecheetah) while the 1933f wallet owner was in the process of transferring approximately the same amount to several exchanges.
10,000 BTC buy order was filed last night on Bitmex with 8,030 BTC transferred from a Bitfinex user wallet while the 1933p wallet owner transferred approximately the same amount of BTC to Bitfinex since August, 24th.
Playing with fire with FinCen and SEC, Binance may face a hefty penalty again after already losing 50 percent of its trading business
https://preview.redd.it/hixbz9f3lxm31.jpg?width=1200&format=pjpg&auto=webp&s=43896de84a3693d840c84057c0314af71718f0a3 What is Zcoin? Zcoin, also referred to as XZC or Zerocoin, is an open source decentralized cryptocurrency that provides privacy and anonymity for its users when making transactions. To achieve its privacy and anonymity, Zcoin uses zero-knowledge proofs via the Zerocoin protocol, which is at this moment in time one of the most cited cryptography papers. According to Wikipedia, in cryptography, a zero-knowledge proof or zero-knowledge protocol is a method in which one party proves to another party (the verifier) that a given statement is actually true. In other words, in a transaction with Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default, leaving you vulnerable. All it takes is one link to your personal information or IP to find out the origin of the coins. However, when you trade with Zcoin’s Zercoin feature, your transaction history is not linked to the actual coins. Only the receiver and sender know that the funds have actually been exchanged.
How Does Zcoin Work?
Zcoin works on the Zerocoin protocol by enforcing Zero-knowledge proofs. Here are the components of Zcoin to explain how it works. Mint: When sending a private transaction with Zcoin, all you need to do is select the number of coins you want to mint. Post that your normal Zcoin balance would reduce automatically and you will be credited with new coins and no transaction history. In essence, your old coins are burned cryptographically, which prevents anyone else from using them again and being directed to your transaction history. You get credited with new coins with no history, while the total supply is maintained. For now, you can only mint in denominations of 1, 10, 25, 50 and 100. If you choose ‘100’ coins to be minted, for instance, you will instantly be credited with 100 new Zcoins with no history attached to them.
Spend: When you want to make a private transaction, you will be required to use these ‘100’ newly minted coins. From this pool of funds, you can now send any amount in any denomination to anyone anonymously because no history is attached to it.
Repeat: You can ‘mint’ and ‘send’ Zcoins any number of times at anytime with your privacy intact.
Zcoin seeks to improve things that Bitcoin hasn’t been able to so far, some of which include fungibility, privacy and miner’s centralization. Users of Zcoin can enjoy full fungibility and privacy along with demolishing miner’s centralization by implementing a better proof of work algorithm called MTP. Total Zcoin supply Only 21 million units of Zcoin will ever be produced. Currently, there are about 3.4 million units in circulation, with the rest yet to be mined. But the total supply has increased by 388450 XZC units after a Zcoin code bug, which the team refused to roll back due to economic reasons, which is why the total supply stands at approximately 21.4 million. Every 10 minutes, a Zcoin block is mined and 50 coins are generated, making 72,000 Zcoins per day. Market cap of Zcoin According to CoinMarketCap, the total circulating supply of Zcoin is 5,757,841 XZC and the current unit price is $9.6. That makes the market cap approximately $55 million*.* https://preview.redd.it/qw2igvupoxm31.png?width=1080&format=png&auto=webp&s=cfaa195d5d75ba8f20e5894d0351b2eabf76825a
How To Buy Zcoin Cryptocurrency
If you are looking to get some Zcoin, here is a list of resources where it can be bought from.
Atomars – Supported pairs are XZC/BTC, XZC/ETH, XZC/USDT
Binance - Supported pairs are XZC/BTC, XZC/ETH, XZC/BNB
Note: At the moment, buying XZC in fiat currencies such as USD, EUR, or GBP is quite difficult. https://preview.redd.it/rrwao97woxm31.png?width=1460&format=png&auto=webp&s=442bf152f86a63300c5c4a029bb07369a69e6f70 Zcash: Zcash is a decentralized and open-source peer-to-peer cryptocurrency that provides strong privacy protections. It was created as a fork of Bitcoin and, like bitcoin, it also has a hard limit of 21 million coins. Unlike bitcoin, however, Zcash offers total privacy for its users maintaining the absolute anonymity behind each transaction along with the parties and the amounts involved in it. PIVX: PIVX, which stands for Private Instant Verified Transaction, is an open-source, decentralized form of digital online money that uses blockchain technology. This makes it easy to transfer all around the world in an instant with low transaction fees with market leading security & privacy. PIVX focuses on privacy, security, anonymity, and instant transactions. Monero: Monero is a fast, private, secure and untraceable digital currency system that uses a special kind of cryptography to keep all its transactions 100% unlinkable and untraceable. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity. Some Zcoin misconceptions There are some misconceptions regarding Zcoin:
Some believe that, since Zcoin has a trusted setup that allows indefinite minting of coins, it is not safe. This is untrue. Of course, to start with they had to use a trusted setup because they have an auditable total coin supply that prevents any form of cheating. This downside however, is being taken care of by removing this trusted setup in the near future and when that happens, Zcoin will be one of the serious coins to count on for privacy.
Zcoin has been considered as Zcash’s fork but that is also not true because Zcash is based on the Zerocash protocol whereas Zcoin was started from scratch by applying Zerocoin tech.
Now that some of the Zcoin’s misconceptions have been cleared, here’s a look into its future.
Zcoin’s Future & Roadmap
Zcoin’s future is quite promising and worth watching based on these interesting milestones on their roadmap:
Zcoin is the first coin to implement MTP proof of work, which makes it possible for general masses to mine Zcoin with GPUs and CPUs. MTP doesn’t allow costly ASIC-like miners to mine XZC coins.
Zcoin is also implementing Znodes to make their cryptocurrency more decentralized and anonymous. These Znodes will be like masternodes and facilitate anonymous transactions as making an anonymous transaction single-handedly is quite computational.
Znodes will be incentivized by reducing some portion of the founder’s reward. Also, the surplus funds that get generated from the founder’s reward reduction would be used for hiring new developers and increased marketing efforts.
Another agenda on their roadmap is to bring inbuilt Tor or some IP obfuscation mechanism that will make it completely anonymous.
Apart from these, some innovative and exciting things like sigma protocol, decentralized anonymous voting and Zcoin Labs are on their roadmap, making this project worth checking out.
Last but not least, its recent price is a good indicator of its healthy market sentiment and shows that there are people who understand this project’s worth. Just to put things into perspective – a unit of Zcoin was priced $2 in March 2017 and now it is $37*.*
Zcoin Team & Progress
Zerocoin is a cryptocurrency proposed by professor Matthew D. Green, a professor of Johns Hopkins University, and graduate students Ian Miers and Christina Garman. It was proposed as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency and released to the public by Poramin Insom, the lead developer, as Zcoin in September 2016. Some of the notable dev members of the team are listed below. Poramin Insom Founder and Core Developer Poramin Insom created what was the world's 4th most valuable cryptocurrency in February 2014. He is also the world's first person to implement stealth addresses in QT-Wallets, improving cryptocurrency anonymity. He earned a master’s degree in Information Security from Johns Hopkins University, where he wrote a paper on a proposed practical implementation of the Zerocoin protocol. Alexander N. Developer Alexander N. aka Aizensou is a full-stack developer who has experience in many programming languages (C++, C#, Python, Perl, Java etc.) and has been involved in the cryptocurrency space since 2013. He has a broad development portfolio from low level APIs in Python and C++ to Android native applications in Java. In addition to his involvement in cryptocurrencies, Alexander was doing his P.h.D. in machine learning at a German university from 2012 to 2016. Saran Siriphantnon Developer Saran Siriphantnon is the CTO of Satang.co/Satoshift, a fintech company focusing on creating an open financial system for Southeast Asia. He served as President of the Computer System Administrator Group at King Mongkut's Institute of Technology Ladkrabang. Tadhg Riordan Solidity Developer Tadhg Riordan is a 24 year old Software Developer from Wexford, Ireland. He recently completed his MSc from Trinity College Dublin, where he worked with Blockchain privacy mechanisms, focusing particularly on Zero-Knowledge Proofs and the Ethereum platform. He is a strong advocate for the adoption of cryptocurrency and for complete financial privacy. Apart from these, their team comprises of other developers, community managers, support personnel and advisors who maintain the required balance.

Unique/Key Features Against Its Competitors:
Anonymous transactions. The project establishes a notably higher level of anonymity and seeks to bypass current analysis techniques which governments use to reveal the identity of users.
Not subject to transaction graph analysis. Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands.
Innovative process. Tokens are burned cryptographically and replaced with new coins without a transaction history. This actively prevents anyone else from using the tokens again and stops the public from being directed to a user's transaction history.
Transparency focused. Zcoin's main advantage is its auditable money supply.
Cardano (ADA) was created by a team led by Charles Haskinson, who previously worked on Ethereum, but left the number of cryptocurrency developers before the ICO. In 2014, he and Jeremy wood formed IOHK. In the same year, a group of Japanese investors signed a 6-year contract with this firm to create a blockchain project based on the use of algorithms for independent execution of exchange operations with different types of assets. https://preview.redd.it/2i65etfaxmt31.png?width=308&format=png&auto=webp&s=29c9fbda1552a59c33452e60afb1bd1b8d6c3d48 The platform was named after Gerolamo Cardano, an Italian mathematician, engineer, philosopher and astrologer. The Ada token was composed of 3 letters of the scientist's surname so that the name of the world's first female programmer-Ada Lovelace - turned out. The currency ICO was held in several stages in 2015-2017. as a result, $62 million was collected during operations only within the ADA Coin system. Until 2019, the developers plan to launch a number of decentralized applications and services for the implementation of smart contracts. In the beginning, the team warned that the low speed of operations (only 5-10 transactions per second) can affect the rate of cryptocurrency. Experts plan to increase the speed of transactions by introducing the system of bandwidth nodes, the Protocol of which will be written in the programming language Haskell. Also prevent the success of the project could reputation of the author of the idea of Charles Hoskinson, who left his previous job without explanation. But the cost of the coin was not affected by these factors, the prospects for the project are good. Cardano Presentation The success of the project is also facilitated by the fact that it is engaged in 3 institutions performing different functions:
IOHK is responsible for the construction of the siege system. This institution is engaged in the technical side of the platform, its improvement.
The Cardano Foundation is located in Switzerland. Responsible for the control of the organization and its development, standardization and protection of technologies.
Emurgo is based on the Isle of man. The organization was created to promote the company's products in the market.
The goal of the creators of the project is a sustainable system that is able to attract investment and thereby support itself.
MAIN FEATURES OF CARDANO COIN
Cardano (ADA) is a cryptocurrency whose task is to secure smart contracts between users on terms beneficial to both parties. Such principles of asset exchange will be the basis for further development of digital currencies. The Ada token has many pluses, but there are also minuses.
Democracy in the control of transactions and mining.
Scientific approach in the development of the mathematical block of the platform, allowing to have a good traffic generation.
High degree of protection against hacker attacks.
Protection of users from unscrupulous partners.
Using test software.
Incomplete platform management.
No protocols for long-term planning.
Insufficient control over the data provided by users.
HOW TO MINE CARDANO
The Cardano platform is based on the Proof of Stake algorithm. This means that the chances of a miner to create a block are directly proportional to the assets available to him, the results of work on solving a mathematical problem do not matter.
Advantages of Cardano mining:
No expensive equipment is required.
Don't need a lot of electricity.
WHERE AND HOW TO BUY CARDANO ADA CRYPTOCURRENCY
Cardano coins are traded in pairs with other cryptocurrencies on most exchanges (Finance, Bitrix, Http, Upbit, Bithumb, Cryptopia, etc.). There are exchangers (Prostocash, Xchange, 60 cek) and Exmo exchange, where you can buy Cardano cryptocurrency for rubles and other Fiat currency, after exchanging it for bitcoins or ethers. You can pay in exchangers via PayPal or Bank card. Purchase instructions ADA:
To buy in exchange for Bitcoin or Etherium.
Register on the exchange and install a wallet with Cardano support.
Exchange purchased bitcoins or ethers for Cardano.
Withdraw ADA to wallet.
Purchase on Binance Crypto exchanges provide the ability to store funds, but it is better to withdraw tokens to the wallet immediately after purchase. If this is not possible, you should take care of the security of your account. Asset storage is better not to trust little-known exchanges.
Until March 2018, the only e-wallet in which ADA could be stored was Daedalus. There are versions for Windows, Mac and Linux. The wallet is suitable for anonymous transactions. The Cardano team plans to issue a debit card that can be replenished through this e-wallet. Daedalus installation instructions:
Find the Get started tab and go to Deadalus wallet.
Click on Download, download the app.
Open the file, configure the installation settings.

This means that the currency can be withdrawn using the Centra card in 36 million terminals around the world. Web wallets are popular because of convenience. Many sites offer to download them to store ADA, but this should not be done, so as not to fall for the tricks of scammers. On the official website of the company there is no data on cooperation with owners of online wallets.
WHAT ARE THE PROSPECTS FOR THE ADA CRYPTOCURRENCY
Given the big plans of Cardano developers, the forecast for 2020 regarding this cryptocurrency is good. If the team implements its ideas to expand the use of coins, ADA may become popular in the market after a while, despite the fall in user confidence in cryptocurrencies. Road map of Cardano The author of the platform Hoskinson said that the work on scaling the data will not yield results until 2019. Developers want to introduce innovative technologies into their project, their creation and research takes a lot of time. By the end of the year, it is planned to standardize the protocols and improve the reliability of the system, but the achievement of these goals may be delayed due to the complexity of the ideas. At this stage of operation of the platform, information about the use of high technologies in support of Cardano's work is not proven. Cryptocurrency faces competition among firms providing such services. It interferes with its development. Specialists working on improving Litecoin and Dash use similar principles when conducting transactions. Ripple plans to become an element combining currencies recognized as official and digital assets, making it more attractive to investors. The exclusivity of the project is that its development is scientifically justified. But this is not a significant advantage, as most traders do not want to spend time figuring out the details of the technical side of the project, and are interested in its functionality. If the Cardano project team fulfills its plans by the end of the year, the prospect of this currency is quite good. The success of ADA depends on how convenient the token will be to use.
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.

$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC crash discussed
This is the 4th post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The facts that part of this funds (>13%) have been transferred in the past month to Bitfinex, Binance and Bitmex exchanges is discussed here.
The origin of the bitcoins was originally discussed here.
A deep-dive into the wallet activity was discussed here.
Today I am writing a short update to discuss the origin of the funds and some events that could be related both to this wallet and yesterday's price crash. Wallet's origin This question has been discussed a lot by the crypto community in the past year. Here is a summary of the most probable hypothesis for the wallet's origin:
Wizsec, a prominent Bitcoin security expert, seems to be pretty sure that the wallet belongs to a MtGox hodler and early investor, who is not a DPR or a SilkRoad user, per his Twitter post: https://twitter.com/wizsecurity/status/1037030003068653569 Finally, Wizsec and I agree that this wallet is not CSW`'s wallet despite it is mentioned in several court documents. Wizsec spent a lot of time debunking CSW's ownership claims earlier this year: https://twitter.com/wizsecurity/status/968337084837781504 What do you think about this wallet origin? ` BTC price crash Also, I wanted to report some events that could be related to this 1933f wallet activity:
$100M USDT were transferred (reported by u/whalecheetah) while the 1933f wallet owner was in the process of transferring approximately the same amount to several exchanges;
a 10,000 BTC buy order was filed last night on Bitmex with 8,030 BTC transferred from a Bitfinex user wallet while the 1933f wallet owner transferred approximately the same amount of BTC to Bitfinex since August, 24th. Was this deal prepared or was the buyer a bitcoin angel?
What is GRS? A true All-in-One cryptocurrency backed by Grøstl-512 PoW algorithm
GRS is a Bitcoin-based Proof-of-Work cryptocurrency founded in March 2014 with 105M Max supply which uses Grøstl-512 https://en.wikipedia.org/wiki/Gr%C3%B8stl algorithm, a NIST hash function competition SHA-3 finalist. There are no ASICs known at the moment, and an alternative derivate of the algorithm is already developed to deploy on fork if an ASIC is ever created. It was the first cryptocurrency to implement Segregated Witness (SEGWIT) and to make a Lightning Network transaction in the mainnet. The main features are: Instantaneous transactions, near-zero fee TXs, wallets for every platform, including iOS apple-approved wallets, all of which work flawlessly, Samourai wallets for hidden transactions and wallet funds. GRS also has the ability to make payments using SMS, without needing a mobile internet connection, and address protection, the blockchain does not accept non-valid addresses. Funds are prevented to get easily lost if a mistake is made in the address entry. The development releases are done quarterly and is done on the 22nd of March, June, September and December. The team has a policy of never pre-announce announcements. All announcements not in the development release are announced on surprise. This has never been breached. All of what has ever been in the roadmap has been released fully and without delay. Next development released is expected to include Trezor and Ledger Hardware wallets and possibly the integration to Rootstock (RSK) smart contracts. The coin development has never been through any kind of drama. Developers are active in the Telegram and community is pretty focused on technology and long-term real world adoption by sharing the word to merchants, as it is an Open-Source product ready for use which is gaining adoption by small merchants around the world. The coin is currently valued at around $1.3 and has a market cap of around $94M. The circulation is now 69.9M and the main exchanges where it's traded are: Upbit (South Korea), Binance (Hong Kong, soon Malta) and Bittrex (U.S.A.).
