Misconception About Peer-to-Peer Messaging
- Most popular messaging apps like Skype or WhatsApp are not truly peer-to-peer, they rely on central servers. - True peer-to-peer means direct device-to-device communication without any middleman or server in between.
Keet’s Identity and DHT Discovery
- Keet uses an identity system similar to a Bitcoin wallet with cryptographic keys for securing user identity. - It leverages a Distributed Hash Table (DHT) where devices discover and sync with each other directly, without central servers.
Local State Sync with Append-Only Logs
- Keet synchronizes local state between a user's devices by sharing cryptographic identity keys peer-to-peer. - Each device appends actions to a private, append-only log that only the user can access, preserving data privacy.
