Forks occur when the software of different miners become misaligned. It's up to miners to decide which blockchain to continue using. If there isn't a unanimous. A crypto fork occurs when a community changes protocols; often it's accompanied by miners refusing to upgrade their costly equipment. Forks don't occur just on. A fork is a change to the blockchain's underlying protocol. A blockchain fork is an important upgrade to the network and can either represent a radical change.

Bitcoin XT is no longer available, with its original website now defunct. When Bitcoin XT declined, some community members still wanted block sizes to increase. In response, a group of developers launched Bitcoin Classic in early Unlike XT, which proposed increasing the block size to eight megabytes, classic intended to increase it to only two megabytes.
Like Bitcoin XT, Bitcoin Classic saw initial interest, with about 2, nodes for several months during The project also still exists today, with some developers strongly supporting Bitcoin Classic. Nonetheless, the larger cryptocurrency community seems to have generally moved on to other options.
Bitcoin Unlimited has remained something of an enigma since its release in early The project's developers released code but did not specify which type of fork it would require. Bitcoin Unlimited set itself apart by allowing miners to decide on the size of their blocks, with nodes and miners limiting the size of blocks they accept, up to 16 megabytes. Despite some lingering interest, bitcoin unlimited has largely failed to gain acceptance. Put simply, SegWit aims to reduce the size of each bitcoin transaction, thereby allowing more transactions to take place at once.
SegWit was technically a soft fork. However, it may have helped to prompt hard forks after it was originally proposed. In response to SegWit, some bitcoin developers and users decided to initiate a hard fork in order to avoid the protocol updates it brought about. Bitcoin Cash was the result of this hard fork. It split off from the main blockchain in August , when Bitcoin Cash wallets rejected bitcoin transactions and blocks.
Bitcoin Cash remains the most successful hard fork of the primary cryptocurrency. As of June , it is the eleventh-largest digital currency by market cap , owing in part to the backing of many prominent figures in the cryptocurrency community and many popular exchanges.
Bitcoin Cash allows blocks of eight megabytes and did not adopt the SegWit protocol. Bitcoin Gold was a hard fork that followed shortly after bitcoin cash, in October The creators of this hard fork aimed to restore the mining functionality with basic graphics processing units GPU , as they felt that mining had become too specialized in terms of equipment and hardware required.
Although it was initially possible to mine bitcoin using personal laptops and desktop computers, the growing mining difficulty, as well as the advent of Application Specific Integrated Circuit ASICs hardware created specifically for bitcoin mining, has made it all but impossible to profitably mine bitcoin at home using the processing speed of an individual computer. Some bitcoin forks, including Bitcoin Gold, have attempted to make bitcoin more accessible by changing the hardware necessary to establish a network connection.
One unique feature of the Bitcoin Gold hard fork was a "pre-mine," a process by which the development team mined , coins after the fork had taken place. Many of these coins were placed into a special "endowment," and developers have indicated that this endowment will be used to grow and finance the bitcoin gold ecosystem, with a portion of those coins being set aside as payment for developers as well.
Generally, Bitcoin Gold adheres to many of the basic principles of bitcoin. However, it differs in terms of the proof-of-work PoW algorithm it requires of miners. When SegWit was implemented in August , developers planned on a second component to the protocol upgrade. This addition, known as SegWit2x , would trigger a hard fork stipulating a block size of two megabytes.
SegWit2x was slated to take place as a hard fork in November However, a number of companies and individuals in the bitcoin community that had originally backed the SegWit protocol decided to back out of the hard fork in the second component. To some extent, the backlash was a result of SegWit2x including opt-in rather than mandatory replay protection; this would have had a major impact on the types of transactions that the new fork would have accepted.
On November 8, , the team behind SegWit2x announced that their planned hard fork had been canceled as a result of discrepancies among previous backers of the project. The simplest way to conceptualize a fork in a cryptocurrency's blockchain is to imagine that the fork introduces a new set of rules for bitcoin to follow. After a fork, bitcoin's blockchain diverges into two potential paths forward.
After a new rule is introduced, the users mining that particular bitcoin blockchain can elect to follow one set of rules or another. This choice is similar to a fork in the road. The two biggest bitcoin hard forks are Bitcoin Cash and Bitcoin Gold, although there have been other, smaller forks. Forks are typically conducted in order to add new features to a blockchain.
Bitcoin has undergone many different forks since it was first introduced in Each of these splits has created new versions of the bitcoin currency. Bitcoin was released as an open-source code, and it was intended to be improved upon over time. Bitcoin forks are a natural result of the structure of the blockchain system, which operates without a central authority.
The first major bitcoin fork was in late Any hard fork can have a profound impact on the cryptocurrency; it is often an unstable time for the cryptocurrency. In some cases, the community will be divided about the necessity and the impact of the changes that are being instigated by the fork. In addition, the price of the cryptocurrency is generally very volatile around the time of a hard fork. In a matter of years, bitcoin has already spawned a large number of forks.
While no one can say for sure, it's likely that the cryptocurrency will continue to experience both soft and hard forks into the future as well, continually growing the cryptocurrency community while also making it increasingly complicated.

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 A more recent hard-fork example is of Bitcoin in , which resulted in a split creating Bitcoin Cash.
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. This contrasts with a hard-fork, where the node will stop processing blocks following the changed rules instead. 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.
The taxation of cryptocurrency splits varies substantially from state to state. A few examples include:. The ATO does not classify cryptocurrency splits as taxation events. 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. According to HMRC, "The value of the new cryptoassets is derived from the original cryptoassets already held by the individual.
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. As of September , it is believed that more than 2. However, there is a growing belief that this guidance may well be challenged in the courts.
According to the guidance published by IRS, provided the taxpayer is in possession of the keys, they are obliged to pay tax for the new cryptocurrency using the fair market value of the cryptocurrency as their income.
