What is a fork?

In the context of cryptocurrencies, a fork occurs when there is a change to the underlying rules or protocol of a cryptocurrency network. This can happen for a variety of reasons, such as to fix bugs, improve performance, or implement new features.

There are two main types of forks: hard forks and soft forks.

A hard fork occurs when the new rules being implemented are incompatible with the existing rules, resulting in the creation of a new blockchain that is separate from the original one. This means that the new blockchain and its associated cryptocurrency are distinct from the original one, and any transactions or balances on the original blockchain are not carried over to the new one. A hard fork often results in the creation of a new cryptocurrency.

A soft fork, on the other hand, occurs when the new rules being implemented are compatible with the existing rules, and the new blockchain is able to continue using the same network and cryptocurrency as the original one. This means that transactions and balances on the original blockchain are carried over to the new one, but nodes that have not upgraded to the new rules may not be able to validate new transactions.

Forks can be contentious, with different factions in the community having different opinions on the proposed changes. In some cases, forks can result in a split in the community, with different groups supporting different versions of the cryptocurrency.

In summary, a fork in the context of cryptocurrencies occurs when there is a change to the underlying rules or protocol of a cryptocurrency network, which can result in the creation of a new blockchain and cryptocurrency. Hard forks and soft forks are the two main types of forks, with hard forks resulting in a new, separate blockchain, and soft forks allowing for continued use of the same blockchain and cryptocurrency with updated rules.
