Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

batching in Bitcoin

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.

Bonus content: UTXO consolidation
  1. 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
  1. A timeline
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.
  1. Analysis
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.
  1. Conclusion
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.
  1. 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.

60% bitcoin hasn’t moved in year despite 220% price bump in 2019

This is the best tl;dr I could make, original reduced by 66%. (I'm a bot)
The price of bitcoin has risen over 220% since January - but longterm holders are keeping their cool.
21.5% of circulating bitcoin hasn't moved in five years Delphi Digital determines how long bitcoin has been held by sorting its " Unspent Transaction Output" data.
According to Delphi Digital's analysis, 60 percent of bitcoin's circulating supply hasn't moved in at least a year, as indicated on the chart by the green line.
Traders have sent lots of bitcoin to Binance To gauge market sentiment, Delphi Digital checked the amount of bitcoin that has flowed through major cryptocurrency exchanges like Binance and Bitfinex.
Delphi Digital explained the surge in bitcoin outflows makes sense, as those who recently bought may seek to take their cryptocurrency off-exchange in preparation to hold.
As for what comes next for the cryptocurrency market, Delphi Digital expressed that some may see the recent run past $13,000 as a "Blow off top," which could see bitcoin move side-ways for a while.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

Integrated into Blockchain Financial

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

Atomic Swap with USDT: Swap Online solution in two hundred lines of code

Atomic Swap with USDT: Swap Online solution in two hundred lines of code
https://preview.redd.it/3mx7amtio9g11.png?width=696&format=png&auto=webp&s=f2bd956843196fa2f51048a86f9608b6e714f62e
On the eve of the release on the mainnet, the team of the cross-chain wallet Swap Online is publishing a research study and the code of the atomic swapusing USDT.

USD Tether — the equivalent of the dollar on Omni Layer

The solution described above with the protocol “over” the Bitcoin network gave life to one of the most controversial cryptocurrency projects of the last two years — Tether. Tether (symbol Tether — ₮, ticker — USDT) is a hybrid cryptocurrency with a rate binding to one US dollar. Moreover, according to the assurances of Tether Limited, the issuer of the given tokens, the “binding” is to be understood literally, as each purchased token of USDT corresponds to one US dollar available at the disposal of the company.
If we take the three largest exchanges based on their daily turnover of transactions at the time of writing (Binance, OKEx and HuObi), and then track the five most popular trading pairs for each, we will encounter USDT in 13 out of 15 cases.

USDT — the token with the largest capitalization in the world.

All this generates great community interest in faster, safer and cheaper solutions for exchanging Tether into other currencies. Obviously, such a solution could be atomic swaps, which are instant, decentralized cross-chain exchanges. The Komodo laboratory, the main headliners of this technology, who presented it in the autumn of 2017, reported on the successful exchange of KMD to USDT carried out on the BarterDEX platform, Komodo’s own exchanger.
https://preview.redd.it/z7tx3cv0p9g11.png?width=597&format=png&auto=webp&s=f0944434f691d69ae45c5b80e00fed2736423f7a
At the same time, according to our data, the developers of Komodo made a swap on the ERC20-a version of Tether, which is only available in 3% of cases. Approximately 60 million USDT from global turnover can thus be exchanged using this method, which, obviously, cannot be considered as a solution to the problem. Striking examples of imperfections of existing solutions can be found even on Etherscan.

This fall, the team of Swap Online is ready to present an atomic swap with Tether. And here’s how we did it.

To carry out the Omni transaction, a user needs to create a regular Bitcoin transaction-transfer of 546 satoshi (minimum) with an additional output storing payload using the OP_RETURN op-code. An example of such a transaction. The payload is a mandatory part of any Omni transaction, as it is a sequence of bytes containing all the necessary information about the transaction.

Let us consider what information is stored in the payload itself

transaction marker — 4 bytes, the mandatory part of any Omni payload is always equal to 0x6f6d6e69 — ASCII code omni. If the first 4 bytes of the sequence are not equal to 0x6f6d6e69, then this sequence is not a payload of Omni.
version — 2 bytes, an analog version of the transaction in Bitcoin. For the described algorithm to work, version 0 is used, or that is the same as 0x0000.
transaction type — 2 bytes, transaction type, for an atomic swap it is sufficient to use only “Simple send” transactions, as simple send is the usual sending of omni currency from its address to the address of the recipient. Simple send corresponds to the transaction type code 0, that is, the next 2 bytes 0x0000. Other possible types of transactions exist in Omni.
token identifier — 4 bytes, identifier of the currency used. For example TetherUS has the identifier 31 or 0x0000001f. All tokens created by the Omni protocol at this time can be seen via the following link.
amount — 8 bytes, for a transaction of type Simple send, this is the amount of the sent currency.
As you can see, payload does not store the addresses of senders and recipients of the transactions, these addresses are determined by the Bitcoin transaction in which the payload output was detected. By scanning inputs, the Omni protocol determines who makes the transfer by finding the output of the corresponding address from among the inputs of the transaction p2pkh.
Thus, for a transfer from Alice to Bob of, for example, 50,000,000 TetherUS, we need to create a Bitcoin transaction where one of the inputs will refer to the p2pkh output corresponding to the Alice address. It is also important that this entry be the first in this transaction (the index of this entry in the received transaction would be is minimal or none at all). One of the outputs of this transaction should be the output of p2pkh to Bob’s address, and another output must have been one of the outputs with the following payload:

Example 1
Example 2

Atomic Swap on Omni Layer

Suppose that Alice and Bob are willing to make an inter-blockchain exchange of cryptocurrencies. Alice wants to exchange the units of any Omni currency, for example TetherUS (the given currency has the currency identifier # 31 in the Mainnet, then in the text we will only talk about this currency of the Omni protocol, since it is the most popular at the moment, but the algorithm below will work for any currency of the Omni protocol as well) for b units of a cryptocurrency working on another blockchain. (Omni works on top of the Bitcoin blockchain, of course, according to the algorithm below it is possible to exchange TetherUS for Bitcoins, but due to their work on one and the same blockchain, this exchange can be done in a different, more efficient way).

Glossary

A — blockchain of Bitcoin.
B — the blockchain of the cryptocurrency for which TetherUS is being exchanged.
a — the sum of TetherUS, which Alice wants to exchange.
b — the sum of the cryptocurrency of the adjoining blockchain B, to which Alice wants to exchange her a TetherUS.

Creating a Transaction

1) Bob generates a random value secret.
2) Bob calculates the secretHash by performing the following operation: secretHash = RIPEMD160 (secret)
3) Bob creates and sends an htlc transaction sealed by secretHash
4) Bob sends Alice a secretHash value, and a hash of the hrlc transaction he created in the previous paragraph in order for Alice to make sure that the correct htlc transaction is actually present in the B blockchain.
5) Alice received from Bob the secretHash and hash of the htlc-transaction Bob created, and is convinced that such a transaction is really present in the B blockchain, and that this is indeed a htlc-transaction sealed by the secretHash value.
6) using the received secretHash, Alice creates the following transaction and translates it into the Bitcoin blockchain:
https://preview.redd.it/oxri5a7gp9g11.png?width=735&format=png&auto=webp&s=14e88db4fc4d1743406939343d42e33352b05782
Let us call such a transaction financing_tx. In fact, it is almost an ordinary Bitcoin htlc transaction that is used in atomic swap with the only difference that in the amount field, 546 satoshi is the minimum number of Bitcoins that can be at the output of the transaction, below this value, Bitcoin counts the transaction as dust and does not conduct it.
7) Alice creates a transaction according to the following scheme:
https://preview.redd.it/awz9uzuhp9g11.png?width=1000&format=png&auto=webp&s=9ca79e77ca6aff631a39ae95dfaa70aa06d695ec
Let us call this transaction redeem_tx. Alice creates such a transaction with two inputs: the first is the input referencing the output of funding_tx, which contains the htlc script. Alice does not sign this script, that is, the SigScript field remains completely empty. The second input is the input referring to any unspent exits of Alice, the main condition is that at this output stage there are enough Bitcoins to pay the transaction fee, and this entry is signed by Alice with her private key with the signature type SIGHASH_ALL (that is, she signs the entire transaction except for SigScript fields on the inputs transaction, which makes this transaction immutable. The outputs of the same transaction are the elementary Simple Send and a TetherUS from Alice to Bob (details of what Simple Send, payload is and how it works can be found in another section).
8) Alice sends Bob the redeem_tx created in the previous paragraph and the one she signed herself.
9) Bob got the redeem_tx sent by Alice, checks it, just looks through the inputs and outputs, making sure that this is really a transaction that Alice should have created using the real algorithm. After that, Bob signs the transaction with his private key and provides the secret value in the SigScript of the corresponding redeem_tx entry.
10) Bob sends the signed redeem_tx transaction to the blockchain, thereby transferring the TetherUS currency from Alice to himself. Note — before carrying out this step, we still need to check that Alice’s address has the necessary amount of TetherUS.
11) Alice looks through blockchain A and gets the value secret and uses it in the B blockchain to transfer the funds using the htlc transaction Bob created in point 3. The exchange ends here.
Stating the obvious: naturally the timelock value used by Bob when creating the htlc-transaction must be significantly longer than the timelock that Alice uses, since her htlc transaction should be spent earlier than the htlc created by Bob. This is necessary so that Bob cannot manage to spend both htlc.

Conclusion

Thus, connecting Omni Layer to Swap Online allows users to cover transactions.

Thermodynamics & Silent Weapons for Secret Wars or Crypto Anarchy 101: Statists Failing & Anarchists Thriving

Crypto Anarchy 101: Statists Failing & Anarchists Thriving
The black-market, the free-market, is what kept people alive throughout the worst of oppressions. The black market has been the art of surviving amidst all types of tyrannies and slaveries. The black market, aka System D, is something that everyone in the world will need to start getting comfortable with. CryptoAnarchy is the ultimate manifestation of complete market freedom, and it is here to stay.
Libertarians are beginning to finally realize their incredible advantage within this new market environment. The unfortunate statist masses have been programmed to feel uncomfortable with the mere idea of complete market freedom. Keep in mind that as of 2009, half of the world’s workers- around 1.8 billion – were employed by System D. The black market is only expected to grow even more so with the incentive structures being built out in order to advance the technological advancements of cryptography.
Humanity has never experienced a true free-market until now. For the first time in history one is beginning to take shape. The traditional business sector is beginning to realize that they are not even mentally equipped for the implications of having applied cryptography that is powered by market incentives. This is evident in their trite attempts at integrating these new technologies with traditional banking and financial systems. Their lack of creativity, and dependence on government, is a clear testament to how much they will be hurt in the coming future.
Statists Double Down after Failure: Tether and Stablecoins
Many within the crypto space have attempted to bridge the gap between legacy banking and cryptocurrencies. Amongst the various attempts at capitalizing with these new technologies, the idea of a stablecoin entered the space via Tether (USDT).
A stable coin is a cryptocurrency that is pegged on a 1 to 1 ratio to the US dollar, or any other asset- like gold- or fiat. Tether operated as a stable coin pegged to the US dollar on a 1 to 1 ratio. The biggest attribute behind stablecoins resided in their ability to provide stability in an otherwise volatile market.
For a long time many within the crypto space were curious about Tether’s means of operating with USD. Earlier this year TDV was the first entity to exclusively reported to its subscribers the origin of Tether’s “secret sauce;” fractional reserve banking.
The laws of fractional reserve banking allowed the Noble Bank of Puerto Rico to provide Tether with the legal means of operating as a stable coin pegged to the US dollar. The Noble Bank recently went bankrupt due to being insolvent. Noble Bank was the bank of Bitfinex and Tether. As a result, Tether and Bitfinex ended their relationship with Noble Bank.
It is important that you as a subscriber move your crypto out of Bitfinex. You should never keep your cryptoin exchanges. When you do this you don’t actually control the private keys of your coins.
(If you are an active trader, please consider using Bisq. Bisq is an open source decentralized exchange that does not control your private keys while trading. It is the most Anarchist exchange in the market right now.)
After losing its partnership with Noble Bank, Bitfinex began banking with HSBC. On October 15th, Bitfinex tweeted that their fiat deposit system was re-enabled. Overall, Bitfinex is still in the midst of reorganizing itself as an exchange with proper banking liquidity. For this reason we are of the opinion that it is best to stay away from Bitfinex until they are more solvent in their banking partnerships.
Tether (USDT) on the other hand is suffering from a lack of proper banking structures. Binance paused all USDT withdrawals and KuCoin, the exchange, also paused USDT deposits and withdrawals.
Tether is currently at around 2.1bn dollar market cap. Tether holders are having a difficult time cashing out of their Tether for USD. It is expected that unless Tether gets its banking situation sorted out, we will see movement out of Tether. This situation has caused the price of Tether to hit a low of $0.90 to the USD. As of writing this, Tether is trading at around $0.97 to the dollar.
The situation for Tether is dire at the present moment. We expect to see many Tether holders drop their Tether for Bitcoin, or other more cryptographically secure cryptocurrencies. This will more than likely be one of the main strategies that will be implemented in order to cash out of Tether.
This overall situation is once again showing us how unstable things are when dealing with fiat. We hope for the market to realize that there is more security in cryptocurrencies than there is in fiat backed stablecoins. Stablecoins will always have the instability of the fiat currencies that they are pegged to. The time will eventually come when people will realize that cryptocurrencies are a better store of value than stablecoins.
In spite of all of the issues circulating Tether, statist entrepreneurs are doubling down on their desire for stablecoins. We are seeing the beginning of what we believe will be a trend in the upcoming future; that is, stable coins pegged to various countries’ fiat and assets like precious metals. The new USD stablecoins recently announced to the market are GeminiUSD, TrueUSD, and Paxos Standard.
Volatility as a Sign of Life in the Market
Contrary to the statist perception on volatility, one can also view volatility in crypto as proper to a market that is fully alive. Crypto, for the first time in history, freed the market from bankster manipulation. Arguably, volatility is to be expected in an unregulated free-market where everyone in the world is for the first time welcomed to participate.
In comparison to the legacy financial system, crypto is fully alive while the former is handicapped by regulations, coercion, and disconnected from true free-market signals. That is, volatility signals of a free-market that breathes freely for the first time. Volatility is indicative of a market that is fully alive.
The desire for individuals to attach crypto to the legacy financial system, under the pretense of “less volatility,” is indicative of individuals that will have a hard time operating outside the bounds of regulation and government coercion. As long as we have statists uncomfortable with Anarchy, we will have stablecoins pegged to fiat.
Various Libertarian entrepreneurs are also beginning to dabble with the idea of a stablecoin that is pegged to precious metals. The challenge of these projects will be the same regulation that oversees fiat. Remember that the difference offered to the world by cryptocurrencies resides in crypto’s ability to operate freely within System D, without regulation. It is this new market, the true free-market, that for the first time is unstoppable.
Bitfinex’s Effect on EOS
Bitfinex is one of the entities that holds the greatest amount of votes for EOS Block Producers (BPs). For this and other reasons, we are currently expecting a shakeup of votes for selected top BPs. It is important that you remain attentive to the happenings within EOS and move your votes accordingly.
We will soon be coming out with more details on our perceptions regarding various BPs.
There are various discussions regarding BPs pending arbitration. This is a good thing. All shakeups lead us closer to more transparency and accountability. This should not directly affect the price of EOS, aside from what will result from the expected FUD of future BP shake-ups.
The Resilience of CryptoAnarchy after Blockstream’s Fake Sidechain
Amongst the various innovations within Bitcoin, sidechains have- for the past 5 years- existed as one of the holy grails of innovation. Blockstream, as a company, was put together to manifest sidechains. They sold us the concept of a sidechain as they were sourcing capital during their first rounds of investment; this was in October of 2014.
Sidechains were supposed to be delivered by Blockstream as a way to make Bitcoin innovation competitive to that of altcoin innovation. Sidechains were supposed to be “the Altcoin killer.”
After all of this time, Blockstream only delivered Liquid - which is not a sidechain- and called it a “sidechain.” That is, Liquid is not a sidechain when properly defined. Liquid is a multi-signature layer that allows for multiple exchanges to pool their money together to transfer funds amongst themselves. Liquid is not a true sidechain, it is more precisely a multi-signature wallet.
Calling Liquid a “sidechain” was just a marketing scheme by Blockstream in order to impress the illusion that they had delivered what they had promised. They didn’t. Blockstream gave up in attempting to create a true sidechain and created a multi-signature wallet instead. Keep in mind that Liquid is a “private sidechain.” Note that a proper sidechain ought to be made with open-source innovation in mind. Many of us see the actions of Blockstream as a bait and switch marketing scheme.
(For the rest of this article I will use the words “Drivechains” and “sidechains” interchangeably as synonyms. Drivechains are what sidechains originally were supposed to be- according to the original Blockstream Sidechain white paper. Blockstream’s bait and switch marketing scheme led to them calling “sidechain” a multisignature wallet that is not at all what they promoted on their white paper. Paul Sztorc, in an attempt to differentiate himself from the Blockstream perversion of the word “sidechains,” called his development of true sidechains “Drivechains.”)
Drivechain Sidechains
Paul Sztorc, the creator of decentralized prediction markets, was very much looking forward to Blockstream’s creation of sidechains. It was his hope that his decentralized prediction market would run as a Bitcoin sidechain. At about the end of 2015 Sztorc was done with BitcoinHiveMind, his decentralized predictions market (previously known as TruthCoin).
After realizing that Blockstream was not going to deliver on sidechains, as promised, Sztorc felt he needed to build it himself. The creation of his Drivechains started off as a means to an end for Sztorc; he needed true Sidechains for his decentralized predictions market- so he build it himself.
On September 24, 2018 Paul Sztorc announced the launch of the first Drivechain release. This release was accompanied with fervent followingof old-school Bitcoiners that immediately jumped into experimenting with Drivechains on the testnet known as “Testdrive.”
The Drivechain protocol is an alternative to the sidechain project originally proposed by Blockstream. It is a simpler design that enables blockchain compatibility in which the system still utilizes the same 21 million bitcoin ruleset- the Nakamoto consensus.
Drivechains are intended to allow for permissionless innovation without diluting or challenging the value of the main cryptocurrency. Contrary to other means of innovation within crypto, any innovation that comes from a Drivechain sidechain actually adds value to the Bitcoin protocol- for it does not dilute the main cryptocurrency. Satoshi vaguely discussed the importance of the ideas of sidechains and multi-blockchain connectivity on June 17, 2010.
This creation, of providing varied market options, make infighting and political discourses regarding consensus upgrades now seem infantile. Drivechains will provide the market with ongoing competitive solutions for blockchain development. Investors will now be exposed to options that would otherwise have been shunned in a less free environment.
The strategic advantage of Drivechain sidechains is that they will offer investors various options in the form of alternative chains. It is important to keep in mind that Drivechains are available for blockchains with the same UTXO set. That is, Drivechains are available for both BitcoinCore (BTC) and BitcoinCash (BCH).
How Drivechains work
Namecoin was the vision of early Bitcoin adopters of creating a DNS and identity infrastructure based on Bitcoin; that is, .bit DNS. This technology piggy backed on top of Bitcoin mining. That is, if you so chose you could merged-mined Namecoin alongside BTC or BCH. Namecoin can absorb hashrate from BTC or BCH without needing its own miners.
Merge-mining with BTC or BCH is also the process of validating and safeguarding Drivechain sidechains. Unlike Namecoin, Drivechain sidechains don’t require miners to run special software. For Drivechain sidechains miners implement what is known as blind-merge-mining. In blind-merge-mining the nodes of the sidechain run the software, not the miners. This operates under the assumption that the nodes running the software also hold BTC or BCH.
A payment fee is paid to miners to blind-merge-mine the sidechain, in a similar way that Namecoin merge-mining pays a fee. In this process, miners don’t have to run any software- they just passively make money for blind-merge-mining blocks with sidechains.
The main difference with sidechains is that you are not mining another coin like Namecoin, but rather you are mining the same BTC or BCH in another sidechain when you do the blind-merge-mining. Miners don’t get paid with the sidechain, they receive payment from the mainchain that they already trust when they blind-merge-mine. Miners are also economically benefited by always getting paid in the superior coin that they are already intentionally mining; BTC or BCH.
As BTC or BCH moves in and out from the mainchain to a sidechain, there might be claims of ownership that may cause disputes. Drivechain prevents this by emphasizing the superiority of the mainchain over sidechains. Sidechains have to report on exactly what it is doing- at all times- to the main chain. Whenever a sidechain wants to transfer money back to the mainchain it has to do it very slowly. This safeguards the network from theft. The slow movement of funds from the sidechain to the mainchain can be arbitrage by individuals who will be willing to purchase sidechain receipts for BTC or BCH coming from sidechains at a discount. People will also be able to do atomic swaps between chains in the near future. (Atomic swaps, or atomic cross chain trading, is the exchange of one cryptocurrency to another cryptocurrency, without the need of trusting a third-party).
It is the intent of Drivechains to create the interaction of miners with sidechains as seamless as possible. However, it is still important to have guarantee that money ends up in the right place. This is the reason for the slow movement of funds from sidechains to the mainchain.
The movement of a certain amount of transactions coming from a sidechain to the mainchain is batched up into one transaction with its own transaction ID. This transaction is frozen in place where miners and developers can examine it for at least a month (there are talks of even making this process longer between 3 to 6 months). During this time miners vote on whether to allow the payment to go through or not. Upon receiving enough upvotes, the batched up transactions are released unto the mainchain. The slowing down of movement of BTC or BCH from sidechains to mainchain decreases the threat of miners stealing BTC or BCH from a sidechain.
The sidechains are always watching the mainchain, so they know to credit people immediately when the mainchain sends money to it. Sidechains also know when the miners have accepted the release of batched up locked funds that are released unto the mainchain. Once the sidechain receives notification of the miners acceptance of funds in the mainchain, the sidechain destroys the funds that were frozen awaiting miner upvotes.
It is overall acknowledged that sidechains increase the value of BTC and BCH, which eventually make mining more profitable. It would be counterproductive for miners to attack and steal funds from sidechains. That is, miners acting maliciously decreases the value of their own equipment. In spite of this fact, it is good that Drivechains make it increasingly more difficult for theft to occur.
Miners, through their voting process, also get to punish bad sidechain actors. Any malicious sidechain will be cleaned out by miners. This is the opposite of the Ethereum model where anyone can code anything into the Ethereum blockchain, to the point that it could become a detriment to the Ethereum mainchain itself. That is, anyone can create a new ERC20 or ERC721 token without any vetting from the network.
Coins are moved from the mainchain to the sidechain by means of sending coins to an address that represents the sending of funds from the mainchain to the sidechain. Anyone running the given sidechain software will recognize that funds were sent to the sidechain- this will automatically credit the person with the same amount of BTC or BCH on the sidechain. Also, the sidechain is programmed to recognize the reception of funds unto the mainchain address from where it will automatically credit the user the same amount of BTC or BCH unto a sidechain wallet. People on the mainchain don’t have to know anything about this particular address. As far as they know, it is just another address.
Embrace the Spontaneous Order of Market Anarchy It is important that people within BTC and BCH take on a more Hayekian approach to entrepreneurship. Many within crypto are uncomfortable with the mere notion of spontaneous order. It is important that we as Ancaps lead the way in motivating people to experiment with their entrepreneurship.
In the past few years, the desire of individuals to covet the development of crypto has become more apparent. These people need to be ignored. No one is the leader of Bitcoin or crypto development. The best innovators within crypto are those that create tools that empower other entrepreneurs to create more options.
It is this spontaneous order that we should welcome and promote at all times. Many within BTC and BCH will not accept or feel comfortable with the radical spontaneous order enabled by Drivechains. This is good reasonto brush up on your Austrian Economics in order to properly confront minds that are fearful of human freedom.
The Ancap entrepreneurs who are most comfortable with spontaneous order will be the same ones who will produce the greatest amount of value. The development of CryptoAnarchy is guided by the science of praxeology and Austrian Economics. Drivechains are testament to the augmentation of our libertarian order are necessary for CryptoAnarchy to thrive.
Drivechains and Investment Strategy
The philosophical and economic advantage of sidechain innovation is that it enables the development of BTC and BCH with an investor-centric intention. It is the market’s investment that now decides the best means for scaling and development. Politics and propaganda take an almost insignificant backseat to that of market forces. The technology is now readily available for investors to test drive with their BTC or BCH on any given proposed sidechain. That is, you actually get to experience the value, or lack of value of a new innovation without jeopardizing your position as an investor.
All investment decisions are about strategy. Sidechains empower the investor’s strategy by allowing the investor to survey all of the possible value propositions of his/her original investment without having to incur any actual costs. In a similar way, sidechains also provide developers with quick market feedback on the aspects of development that are most favored by the market.
Drivechains are a pivotal step in maturing the crypto space into becoming more conscientious in considering the investment strategy of those buying the coins. It is important for innovators to start taking the investor’s strategy into account. Drivechains force developers to consider what is best for the investor, not just what is desired by a given team of developers.
Here we have not only a better proposition for investors, but also an incentive for developers to use Drivechains in future crypto experimentation. When experimenting with an altcoin, the measure of success is contingent on this new altcoin gathering a new pool of investors to literally buy into the project. With a sidechain you are already dealing with a more seasoned group of investors that will provide you with more accurate market feedback, being that their investment is now fortified by all other sidechain experimentations that they have already tested at no cost.
Altcoins will soon no longer be the locus of innovation within crypto. All future innovation will be offered the option to experiment within BTC or BCH via sidechains. Keep in mind that all previous innovations, already tested in the market by successful altcoins, are now easily adopted by BTC or BCH. It is also important to note that creative experimentation on sidechains do not at all jeopardize the mainnets of BTC or BCH. On the contrary, sidechains will make BTC and BCH much more valuable. When the Drivechain craze begins we will see a BTC and BCH bull run. Don’t be surprised if sidechains are the main reason for the next all time highs.
Statists Failing & Anarchists Thriving
It is important that we understand that the legacy banking system is completely dead. They are barely adopting simulations of cryptocurrencies unto their banking structures to stay alive. Stablecoins are a manifestation of this bankster angst to remain current.
True market innovation is found in the embrace of Market Anarchy. CryptoAnarchy is growing exponentially with tools that are beyond the reach of state megalomaniacs. Drivechains are an example of the CryptoAnarchist tools that will result in further anti-fragility of this new crypto free-market.
Proper Austrian Economic incentive structures coupled with applied cryptography is our lethal weapon against nation states and central banks. Arguably, our Ancap philosophy is what guides applied cryptography in the market towards success. For this reason it is important that we keep revisiting the texts of Rothbard, Mises, Hayek, and Konkin throughout our crypto endeavors. Peace!

Can someone pls help!

Been trying to purchase some VEN for the past 3 days. I transferred over some bitcoin from btcmarkets (Aussie exchange) to binance. On btcmarkets it says it has been processed when I click on the details it takes me to blockchain.info where it says its been unconfirmed.
I understand all this its just I sent over $700 and on the blockchain this has been confirmed where it says unspent in the image below. There is another $186 there which I have no idea where its come from. Just raging seeming VEN double in price since when I sent the money over and there is nothing I can do about it.
https://ibb.co/jMxLMb
If someone can help ill tip you $50 worth of VEN when its all said and done
