Defines the BIP 32 derivation path and extended-key version bytes (zpub/zprv) for HD wallets generating native SegWit P2WPKH addresses.
Bitcoin Cash forked from Bitcoin at block 478558, mined by ViaBTC around 12:37 UTC. The 8 MB, no-SegWit chain became the first protocol fork to leave a lasting separate network.
Defines Bech32, a checksummed base32 format, and the segwit address encoding (bc1.../tb1...) built on it for native v0-16 witness outputs.
Defines the BIP32 derivation path (purpose 49') and address scheme for P2WPKH-nested-in-P2SH accounts, so BIP141 segregated witness wallets sharing a seed fail visibly instead of missing UTXOs.
New SegWit v0 signature-hash algorithm: commits to the input's spent amount, fixes O(n^2) quadratic hashing, and changes OP_CODESEPARATOR/FindAndDelete handling.
Segregated Witness (SegWit) — Bitcoin's most significant protocol upgrade since creation. Separates signature from transaction data, fixing malleability, enabling Lightning, raising block capacity.
Cross-cutting reading of Bitcoin's 2015–2017 block-size war by phase, faction, and turning point: Bitcoin XT, BIP148 UASF, the New York Agreement, Bitcoin Cash, SegWit2x cancellation.
Belgian software engineer (sipa), Bitcoin Core committer since 2011. Author/co-author of BIP-32, BIP-141 (SegWit), BIP-340/341 (Schnorr/Taproot). Initiator of libsecp256k1; Blockstream co-founder.
Genealogy of every Bitcoin protocol fork that left a separate chain alive (Bitcoin Cash, SV, Gold) and the adjacent cryptocurrencies derived from Bitcoin (Namecoin, Litecoin, Dogecoin).
