Heti Összefoglaló¶
Ez a hét Ridestr decentralized ridesharing-gel, Pomade multisig recovery-val, és Damus negentropy-vel telt. plusz 5 év Nostr története visszatekintés.
🗞️ News¶
Ridestr: Decentralized Ridesharing on Nostr¶
Ridestr - P2P rideshare alkalmazás teljesen Nostr-on
Fizetés: Bitcoin + Cashu
Privacy: Progressive location disclosure, NIP-44 encryption
Event kinds: - 30173: Driver availability (geohash-encoded, ~5km precision) - 3173: Ride request with fare estimate - 3174-3175: Ride coordination - 30180/30181: Payment és settlement
Payment security: - HTLC escrow P2PK signatures - Cashu tokens locked payment hash-sel - Single-mint architecture (same mint required)
Location privacy: - Pickup details csak driver arrival után - Destination PIN verification után - NIP-44 encryption minden kommunikáció
Implementation: Kotlin Android, proof verification, NUT-07 state checks
Challenges: Real-time location, payment escrow, reputation systems
Pomade: Alpha Recovery System for Multisig¶
Pomade - Recovery-focused threshold signing service (hodlbod)
Base: FROSTR ecosystem + @frostr/bifrost library
Cryptography: FROST (Flexible Round-Optimized Schnorr Threshold)
Architecture: - Shamir Secret Sharing (2-of-3, 3-of-5, stb.) - Event kind: 28350 (NIP-44 encrypted payloads) - Signing: partial signature aggregation
Recovery methods: - Password-based: argon2id (signer pubkey as salt) - Email OTP
MITM protection: - Each signer generates own verification code - Client-provided prefix - Independent authentication each signer-rel
Spam prevention: Proof-of-work registration (20+ bits, NIP-13)
Trust model: - ⚠️ Colluding threshold signers can steal key - ⚠️ Email providers fully trusted (can intercept OTPs) - Users cannot independently recover full secret key
Recommendation: Migrate to self-custody after onboarding
