Bitcoin Codebase Forks
A historical archive of projects derived from Bitcoin's source code and technical lineage. These include alternative Bitcoin clients, independent-genesis blockchains, descendant codebases, and merged-mined networks that did not inherit Bitcoin's UTXO set.
Bitcoin Client / Protocol Forks
Alternative Bitcoin software implementations and scaling projects that changed or proposed changes to Bitcoin's rules without creating an independent UTXO snapshot at launch.
Bitcoin-Descended Codebases
Independent-genesis networks whose software descends from Bitcoin directly or through another Bitcoin-derived codebase.
Merged-Mined Bitcoin Codebase Forks
Independent-genesis projects that carry Bitcoin-derived code forward without copying the Bitcoin UTXO set, while bootstrapping security through merged mining.
