Self‑Sovereign Identity and Blockchain
summary
Presents a Self‑Sovereign Identity design that anchors identity state to the Bitcoin mainnet by writing only salted hashes on‑chain so no personal data is stored in the ledger. Describes a beta marketplace where banks publish signed certificates, services verify them for a small Bitcoin payment, and users manage revocation and key rotation via a mobile app; it also discusses Bitcoin PoW finality times (10–30 minute confirmations, ~50–60 minutes for full finality), warns about smart‑contract loss risks, and argues private ledgers are effectively trusted databases.
