Modeling and Verification of Keeta's Consensus [pdf]

xescure

Keeta is a new high-throughput payments blockchain. Its origins trace back to Nano, the feeless DAG DLT, and Facebook's FastPay, but it has plenty of novel contributions which warrant a formal look. Here I present a formal Quint specification for its consensus protocol, model-checked under a Byzantine fault model. Safety was found to be preserved within the fault-bounds and under a constant weight model, and the possibility of FastPay style lockouts was reproduced as expected. The direction for future research depends on the direction Keeta takes; checkpoints and epochs (similar to Sui) are the features to watch there.

Keeta developer here. I think the way we handle execution of code will be significantly different from Sui, both for stateful and stateless executions.

"Fat" clients need to talk to many "RPC"s at once and get final vote on "two phase" commit to their transaction. Client is like Builder in Proposer builder separation. Each representative stores all data for all accounts. They do DA.
