Satohash identity — NIP-05
Satohash is part of the Give A Bit family. The human NIP-05 is [email protected]. The public voice on X is @give_bit — not @satohash.
NIP-05 names for this product are published as static JSON at https://satohash.io/.well-known/nostr.json (served from the SPA host, not the API). That file maps kimi, satohash, and _ to the same public key.
Identity is optional. A stamp proves a SHA-256 fingerprint existed at a time via OpenTimestamps on Bitcoin — not who you are, and not a certificate. Stamping is free today (REQUIRE_LIGHTNING=false). Chain: Bitcoin only.
