Beyond blockchain: PARSEC, bringing consensus to the next level with Rust
summary
PARSEC claims a mathematically proven, scalable alternative to blockchain (invented 2018) and is implemented in Rust for the SAFE Network; it uses gossip DAG events, observers and reduction to binary agreement, tolerates <1/3 Byzantine nodes, and targets n log n communication complexity. Membership changes and a concrete coin replace heavyweight DKGs. The code is open source (GPLv3 with linking exception / MIT interfaces), tests include fuzz/property testing that found two real bugs, and development is actively moving prototypes toward production.
