Multi-Round Visibility: A Post-Consensus Ordering Layer for DAG-Based BFT

Pengkun Ren, Dong Hai, Nasrin Sohrabi +1

Directed acyclic graph (DAG)-based Byzantine Fault-Tolerant (BFT) protocols achieve high throughput by decoupling dissemination from agreement and allowing many vertices to be comm…

Proof-Carrying Fair Ordering: Asymmetric Verification for BFT via Incremental Graphs

Pengkun Ren, Hai Dong, Nasrin Sohrabi +2

Byzantine Fault-Tolerant (BFT) consensus protocols ensure agreement on transaction ordering despite malicious actors, but unconstrained ordering power enables sophisticated value e…

Efficient and Secure Sleepy Model for BFT Consensus

Pengkun Ren, Hai Dong, Zahir Tari +1

Byzantine Fault Tolerant (BFT) consensus protocols for dynamically available systems face a critical challenge: balancing latency and security in fluctuating node participation. Ex…
