Add censorship-resistant NIP-05 verification using the Namecoin blockchain.
Users can set their nip05 field to a .bit domain (e.g. alice@example.bit)
or direct Namecoin name (d/example, id/alice) and Amethyst will resolve
the pubkey mapping via ElectrumX instead of HTTP.
Resolution uses the standard Electrum protocol (scripthash-based lookups):
- Build canonical name index script matching ElectrumX-NMC indexing
- Query blockchain.scripthash.get_history for the name's tx history
- Parse NAME_UPDATE script from the latest transaction output
- Extract Nostr pubkey from the name's JSON value
Supports both d/ (domain) and id/ (identity) Namecoin namespaces,
simple and extended NIP-05-like value formats with relay hints,
LRU caching with 1h TTL, and self-signed TLS certificates.
New files:
- quartz: ElectrumxClient, NamecoinNameResolver, NamecoinLookupCache
- amethyst: NamecoinNameService, Nip05NamecoinAdapter, NamecoinVerificationDisplay
- docs: namecoin-nip05-design.md
- tests: NamecoinNameResolverTest
Modified:
- Nip05Client: optional namecoinResolver routes .bit to blockchain
- AppModules: wire up resolver
See docs/namecoin-nip05-design.md for full architecture and protocol details.
