Bitcoin BIPs Reference — Every Bitcoin Improvement Proposal Indexed

A complete, machine-readable index of every Bitcoin Improvement Proposal (BIP): number, title, layer, type and status, from the canonical bitcoin/bips repository. Free CSV/JSON + REST under CC BY 4.0.

Quick answer

A BIP (Bitcoin Improvement Proposal) is the design document used to propose changes to Bitcoin — the equivalent of an internet RFC or a Nostr NIP. This reference indexes 212 BIPs from the canonical bitcoin/bips repository with each one's title, layer (Consensus, Peer Services, API/RPC or Applications), type and status. Core ones to know: BIP-32 (HD wallets), BIP-39 (seed phrases), BIP-141 (SegWit), BIP-174 (PSBT), BIP-340/341/342 (Schnorr/Taproot), BIP-352 (Silent Payments).

The most queryable BIP index on the open web - free CSV/JSON + REST under CC BY 4.0, filterable by status, layer and type. The repo's status terms (Deployed, Draft, Complete, Closed) are preserved; always confirm against bitcoin/bips before building.
