Jimi - What do you think of Spaces Protocol? https://spacesprotocol.org/

Summary: "Are we self-sovereign PKI yet?" by Buffrr (May 6, 2026) buffrr.dev https://buffrr.dev/blog/are-we-self-sovereign-pki-yet/ The article argues that while we have end-to-end encryption in messaging apps (Signal, iMessage, WhatsApp, etc.), it's undermined by a fundamental flaw: you can't reliably know you're using the right public key for someone. Safety numbers, contact verification, and similar features exist but are rarely used, making encryption "end-to-end conditional on the platform being honest." The Core Problem = Binding human-readable names/identities (email, usernames, keys) to public keys still relies on custodial intermediaries: Email: Providers can read, suspend, or hand over accounts; self-hosting is impractical due to spam filters. Usernames: Scattered across platforms with no easy cross-proof (Keybase tried but faded after acquisition). Traditional PKI (for domains): Certificate Authorities (CAs), DNS, and even DNSSEC are vulnerable to attacks like BGP hijacks. Workarounds like Certificate Transparency help detect issues but don't eliminate trust in operators. Every layer assumes trust in someone else (CAs, registrars, providers). The Ideal Solution = A self-sovereign system where a name like grace@key directly and verifiably resolves to a public key - no revocation, suspension, or central authority. Resolving the name is the verification; no manual fingerprint checks needed. Spaces Protocol is presented as a practical step toward that ideal: Names live in a binary Merkle trie, with the root hash committed to Bitcoin (as a tamper-resistant timestamp). Handles (e.g., grace@key) are issued under parent "spaces" (@key). Issuance is off-chain/batched for users; resolution uses Merkle proofs against the Bitcoin-committed root. Records (e.g., Age keys, Nostr pubkeys) are signed and distributed peer-to-peer via Certrelay. Trust anchor: A single 32-byte hash (one global "safety number"). Verified via a desktop tool (Veritas) that checks Bitcoin headers and protocol rules locally. Future: Zero-knowledge certificate (~250 KB succinct proof) for instant, no-sync verification. This creates a "CA without a private key" - trust is reshaped into auditable computation + Bitcoin's proof-of-work, not a compromisable signing key. Considerations & Trade-offs Key rotation/loss: Manageable for rotation; harder for total loss (social recovery ideas exist but imperfect). Issuance: Top-level spaces via burning auctions (slow, anti-squatting); handles via batches/faucet. Adoption: Hardest challenge - needs app integration. Limitations: Trusts Bitcoin's long-term security and software supply chain; doesn't solve the "social" side of identity (reputation, knowing it's the right person). Bottom line: Traditional PKI and identity systems remain custodial. Spaces offers a concrete, working shape for self-sovereign PKI using Bitcoin as a neutral anchor - a missing piece after decades of attempts. It's not fully adopted yet, but the architecture points in the right direction. #Bitcoin #SpacesProtocol #PKI #Cryptography

Are we self sovereign PKI yet? Signal is end to end encrypted in the sense that the keys are end to end. Whether you got the right keys is a different question, and almost nobody asks it. The missing piece, for a long time, has been a way to bind a human scale name to a key without trusting a server, a registrar, or a CA. The shape of that piece is now clear enough to point at.👇 https://buffrr.dev/blog/are-we-self-sovereign-pki-yet/ #Bitcoin #PKI #Cryptography
