What is BIP?
A Bitcoin Improvement Proposal: the numbered document format used to specify and discuss protocol and standards changes.
BIPs range from consensus changes to wallet conventions. BIP-39 defines seed phrases; BIP-32 defines HD wallets; BIP-341 defines Taproot.
A BIP number means a proposal exists and has been assigned an identifier. It does not mean the proposal is accepted, active or good.
