Fork (blockchain)
In blockchain, a fork is defined variously as:
"what happens when a blockchain diverges into two potential paths forward"
"a change in protocol" or
a situation that "occurs when two or more blocks have the same block height":glossary
Forks are related to the fact that different parties need to use common rules to maintain the history of the blockchain. When parties are not in agreement, alternative chains may emerge. While most forks are short-lived some are permanent. Short-lived forks are due to the difficulty of reaching fast consensus in a distributed system. Whereas permanent forks (in the sense of protocol changes) have been used to add new features to a blockchain, they can also be used to reverse the effects of hacking such as the case with Ethereum and Ethereum Classic, or avert catastrophic bugs on a blockchain as was the case with the bitcoin fork on 6 August 2010.
Blockchain forks have been widely discussed in the context of the bitcoin scalability problem.
Types of forks
Forks can be classified as accidental or intentional. Accidental fork happens when two or more miners find a block at nearly the same time. The fork is resolved when subsequent block(s) are added and one of the chains becomes longer than the alternative(s). The network abandons the blocks that are not in the longest chain (they are called orphaned blocks).
Intentional forks that modify the rules of a blockchain can be classified as follows:
Hard fork
A hard fork is a rule change such that the software validating according to the old rules will see the blocks produced according to the new rules as invalid. In case of a hard fork, all nodes meant to work in accordance with the new rules need to upgrade their software.
If one group of nodes continues to use the old software while the other nodes use the new software, a permanent split can occur. For example, Ethereum has hard-forked to "make whole" the investors in The DAO, which had been hacked by exploiting a vulnerability in its code. In this case, the fork resulted in a split creating Ethereum and Ethereum Classic chains. In 2014 the Nxt community was asked to consider a hard fork that would have led to a rollback of the blockchain records to mitigate the effects of a theft of 50 million NXT from a major cryptocurrency exchange. The hard fork proposal was rejected, and some of the funds were recovered after negotiations and ransom payment. Alternatively, to prevent a permanent split, a majority of nodes using the new software may return to the old rules, as was the case of bitcoin split on 12 March 2013.
Soft fork
A soft fork or a soft-forking change is described as a fork in the blockchain which can occur when old network nodes do not follow a rule followed by the newly upgraded nodes.:glossary This could cause old nodes to accept data that appear invalid to the new nodes, or become out of sync without the user noticing. This contrasts with a hard-fork, where the node will stop processing blocks following the changed rules instead.
Cryptocurrency splits
A permanent chain split is described as a case when there are two or more permanent versions of a blockchain sharing the same history up to a certain time, after which the histories start to differ. Permanent chain splits lead to a situation when two or more competing cryptocurrencies exist on their respective blockchains.
Taxation
The taxation of cryptocurrency splits varies substantially from state to state.
Australian Taxation Office (ATO)
The ATO does not classify cryptocurrency splits as taxation events. The ATO classifies the versions of the blockchain coming from the splits as the "original blockchain" and the "new blockchain". In relation to the cost base, the cryptocurrency on the original blockchain should be assigned all the original cost base, while the cryptocurrency on the new blockchain should be assigned cost base zero.
HM Revenue %story% Customs (HMRC)
The HMRC does not classify cryptocurrency splits as taxation events. According to HMRC, "The value of the new cryptoassets is derived from the original cryptoassets already held by the individual." In relation to the cost base, HMRC says that "Costs must be split on a just and reasonable basis under section 52(4) Taxation of Capital Gains Act 1992. HMRC does not prescribe any particular apportionment method. HMRC has the power to enquire into an apportionment method that it believes is not just and reasonable."
Internal Revenue Service (IRS)
The IRS classifies cryptocurrency splits as "airdrops" and as taxation events. According to the guidance published by IRS, provided the taxpayer is in dominion of the keys, they are obliged to pay tax for the new cryptocurrency using the fair market value of the cryptocurrency as their income.

The daily trade on the exchanges (as of Jan 2012) indicates that smaller transactions are becoming the norm, indicating trade rather than investment. In more pragmatic terms, 'fairness' is an arbitrary concept that is improbable to be agreed upon by a large population. Establishing 'fairness' is no goal of Bitcoin, as this would be impossible.bitcoin department bitcoin word

Thus, while large, regulator-friendly, conventional exchanges are good onramps in the developed world, where cryptocurrencies are not (yet) a threat to local sovereign currencies, they aren’t a good fit for states experiencing demonetization or high inflation, which is where access is most impactful. Centralized exchanges must be supplemented by peer to peer exchanges like LocalBitcoins, Hodl Hodl, Paxful — and indeed, they are the venues where trading seems to occur (Venezuelan traders are doing $300m annualized on LocalBitcoins, Nigeria -$170m, Russia close to a billion USD). Wallets which allow for trust-minimized trading like Opendimes are vital here — receiving an Opendime where you can be sure your counterparty doesn’t know the private key beats waiting an hour for six confirmations.invest bitcoin sberbank bitcoin

Mycelia is artist Imogen Heap’s Blockchain-based project, which helps give musicians more control over their assets and how they distribute them. Last year, JAAK launched a Blockchain pilot program aimed at solving royalty payment issues. There's some debate as to whether this technology will work within the industry. Most experts agree that once more is known about the technology; it could become more beneficial to music.bitcoin accepted bitcoin zebra

payable ethereum bitcoin nonce bitcoin экспресс > > you had to become very multi-discipline, you had to understand up to 7Inflation is simply a rise of prices over time, which is generally the result of the devaluing of a currency. This is a function of supply and demand. Given the fact that the supply of bitcoins is fixed at a certain amount, unlike fiat money, the only way for inflation to get out of control is for demand to disappear. Temporary inflation is possible with a rapid adoption of Fractional Reserve Banking but will stabilize once a substantial number of the 21 million 'hard' bitcoins are stored as reserves by banks.txid ethereum
