This week on Nostr Compass: Ridestr launches decentralized ridesharing with Cashu and NIP-44. Pomade enables multisig key recovery via email and OTP. Damus ships negentropy-based DM syncing. Desktop clients like Amethyst and NoteDeck evolve, while Formstr, Shopstr, Jumble, and nostr-tools push upgrades. We explore major new NIPs for community keys, encrypted file sync, and sequence-based event indexing — then reflect on five years of Nostr’s growth.
