Revision as of 01:36, 19 November 2018
Bitcoin forks are defined variantly as changes in the protocol[1] of the bitcoin network or as the situations that occur "when two or more blocks have the same block height".[2] 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.[3]
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.[4]
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.[5][6] The following is a list of hard forks splitting bitcoin by date and/or block:
- Bitcoin Cash: Forked at block 478558,[7] 1 August 2017, for each bitcoin (BTC), an owner got 1 Bitcoin Cash (BCH)
- Bytether: Cross fork from Bitcoin to Ethereum blockchain at block 478558, 1 August 2017.[8] For each 1 BTC you get 1 BTH ERC-20 token.[9]
- Bitcoin Clashic: Forked at Block 478558, 1 August 2017.[10][11][12] For each 1 BTC you get 1 BCHC / BCL.
- Bitcoin Gold: Forked at block 491407,[13] 24 October 2017, for each BTC, an owner got 1 Bitcoin Gold (BTG)
- Bitcoin Diamond: Forked at Block 495866[14][15], 24 November 2017.[16][17][18][19] For each 1 BTC you get 10 BCD.
- UnitedBitcoin: Forked at Block 498777[20], 12 December 2017, For each 1 BTC you may get 1 UB if you take special actions to claim it.
- Super Bitcoin: Forked at Block 498888[21], 12 December 2017.[22] For each 1 BTC you get 1 SBTC.
- Bitcoin Private: Forked at block 511346,[23] 28 February 2018, for each Bitcoin (BTC) or ZClassic (ZCL), an owner got 1 Bitcoin Private (BTCP).
Note that there are numerous other split coins that might not be notable enough to appear in this list.
Intended soft forks splitting from not-most-work block
- The fork fixing the value overflow incident[24] 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)[25]
- CVE-2018-17144 (Bitcoin 0.15 allowed double spending certain inputs in the same block. Not exploited)[26]
Proposed (but canceled) forks
- SegWit2x: This was a planned fork which was later canceled before the split could take place.
