For broader coverage of this topic, see Fork (blockchain) and forks.

Bitcoin forks are defined variantly as changes in the protocol of the bitcoin network or as the situations that occur "when two or more blocks have the same block height". A fork influences the validity of the rules. Forks are typically conducted in order to add new features to a blockchain, to reverse the effects of hacking or catastrophic bugs. Forks require consensus to be resolved or else a permanent split emerges.

Forks of the client software

The following are forks of the software client for the bitcoin network:

All three software clients attempt to increase transaction capacity of the network. None achieved a majority of the hash power.

Intended hard forks splitting the cryptocurrency

Hard forks splitting bitcoin (aka "split coins") are created via changes of the blockchain rules and sharing a transaction history with bitcoin up to a certain time and date. The first hard fork splitting bitcoin happened on 1 August 2017, resulting in the creation of Bitcoin Cash. 

The following is a list of hard forks splitting bitcoin by date and/or block:
  • Bitcoin Cash: Forked at block 478558, 1 August 2017, for each bitcoin (BTC), an owner got 1 Bitcoin Cash (BCH)
  • Bitcoin Gold: Forked at block 491407, 24 October 2017, for each BTC, an owner got 1 Bitcoin Gold (BTG)
  • Bitcoin Diamond: Forked at Block 495866, 24 November 2017. Holders of BTC received 10 BCD/BTC.
  • Bitcoin Private: Forked at block 511346, 28 February 2018, for each Bitcoin (BTC) or ZClassic (ZCL), an owner got 1 Bitcoin Private (BTCP).
  • Bitcoin SV: Forked at block 556766, 15 November 2018, for each Bitcoin Cash (BCH), an owner got 1 Bitcoin SV (BSV).

Intended soft forks splitting from not-most-work block

  • The fork fixing the value overflow incident was controversial because it was announced after the exploit was mined.

Unintended hard forks

Two hard forks were created by "protocol change" definition:

  • March 2013 Chain Fork (migration from BerkeleyDB to LevelDB caused a chain split)
  • CVE-2018-17144 (Bitcoin 0.15 allowed double spending certain inputs in the same block. Not exploited)
