A new lineage/v0 op binds a node's keys in one inscription whose parent is the
node itself: its Taproot and SegWit addresses, its npub and its Ethereum
address. Every key signs the same statement the way its own wallets sign a
message: BIP-322 simple signatures for the Bitcoin addresses, a NIP-01 note
(kind 1, created_at 0) for the npub, EIP-191 for Ethereum. The reducer checks
every proof, binds a standing keyring's keys to its node, lets the newest
keyring replace the older, and retires keyrings at a graduation (the keys
change with the new root) and at a close.
Every account gets an Ethereum key at m/44'/60'/account'/0/0; an org's, at
account 0, is the key tree page's legal-control key and matches its published
vector. Keyring is the ninth verb; Inspect shows each node's keyring and the
statement its keys signed, and Reveal its Ethereum private key. The sample
publishes three keyrings, and lineage's retires when it graduates.
Tests pin BIP-322's published vectors and values cross-checked with
bip322-js, ethers and nostr-tools. The regtest rehearsal, rerun with five
keyrings, confirmed 89 transactions on Bitcoin Core; ord's 26 events fold to
the same trees and keyrings, every proof checked from ord's copy, and the
fixture is re-recorded.
