COOL Is Optimal in Error-Free Asynchronous Byzantine Agreement
Jinyuan Chen
COOL (Chen'21) is an error-free, information-theoretically secure Byzantine agreement (BA) protocol proven to achieve BA consensus in the synchronous setting for an -bit mess…
Ocior: Ultra-Fast Asynchronous Leaderless Consensus with Two-Round Finality, Linear Overhead, and Adaptive Security
Jinyuan Chen
In this work, we propose Ocior, a practical asynchronous Byzantine fault-tolerant (BFT) consensus protocol that achieves the optimal performance in resilience, communication, compu…
OciorABA: Improved Error-Free Asynchronous Byzantine Agreement via Partial Vector Agreement
Jinyuan Chen
In this work, we propose an error-free, information-theoretically secure multi-valued asynchronous Byzantine agreement (ABA) protocol, called OciorABA. This protocol achieves ABA c…
OciorCOOL: Faster Byzantine Agreement and Reliable Broadcast
Jinyuan Chen
COOL (Chen'21) is an error-free and deterministic Byzantine agreement protocol that achieves consensus on an -bit message with a communication complexity of $O(\max\{n\ell, n…
