p2panda-sync

Data- and transport-agnostic sync protocols

This crate provides a data- and transport-agnostic interface to implement custom sync protocols, compatible with p2panda-net or other peer-to-peer networking solutions.

In addition to the generic definition of the SyncProtocol trait, p2panda-sync includes optional implementations for efficient sync of append-only log-based data types. These optional implementations may be activated via feature flags. Finally, p2panda-sync provides helpers to encode wire messages in CBOR.

Features

• Transport- and data-type agnostic trait definitions compatible with p2panda-net
• Efficient and ready-to-use implementation for log-height based sync of p2panda core data-types
• Privacy-first design allowing implementations to reveal as little information as possible during handshake phase
• Generic design to re-use the same sync protocol for very different applications
