Bitcoin Project ↔ Gavin Andresen, Chris Moore, Pieter Wuille, Jeff Garzik, Wladimir van der Laan, Nils Schneider

Bitcoin's migration from SourceForge SVN to GitHub, and the chronological record of developers who received commit access to the GitHub repository in 2011.

BIP 32 — Hierarchical Deterministic Wallets

Pieter Wuille

Introduced hierarchical deterministic (HD) wallets, allowing an entire tree of key pairs to be derived from a single master seed. This eliminated the need for frequent backups and enabled organized key management with parent-child key derivation.

BIP 141 — Segregated Witness (Consensus Layer)

Eric Lombrozo ↔ Johnson Lau, Pieter Wuille

Proposed Segregated Witness (SegWit), the most significant protocol upgrade since Bitcoin's creation. By separating signature data from transaction data, SegWit fixed transaction malleability, enabled the Lightning Network, increased effective block capacity, and introduced a new transaction format — all via a backward-compatible soft fork.

BIP 340 — Schnorr Signatures for secp256k1

Pieter Wuille ↔ Jonas Nick, Tim Ruffing

Introduced Schnorr digital signatures to Bitcoin, replacing ECDSA for Taproot transactions. Schnorr signatures are provably secure, non-malleable, and enable efficient multi-signature aggregation — making complex scripts indistinguishable from simple payments on-chain.

BIP 341 — Taproot: SegWit Version 1 Spending Rules

Pieter Wuille ↔ Jonas Nick, Anthony Towns

Introduced Taproot, the most significant Bitcoin protocol upgrade since SegWit. By combining Schnorr signatures (BIP 340) with Merkelized Abstract Syntax Trees (MAST), Taproot makes complex spending conditions as private and efficient as simple payments, while enabling more sophisticated smart contracts.
