The Latency Price of Threshold Cryptosystem in Blockchains
Zhuolun Xiang, Sourav Das, Zekun Li +2
Threshold cryptography is essential for many blockchain protocols. For example, many protocols rely on threshold common coin to implement asynchronous consensus, leader elections,…
Raptr: Prefix Consensus for Robust High-Performance BFT
Andrei Tonkikh, Balaji Arun, Zhuolun Xiang +2
In this paper, we present Raptr--a Byzantine fault-tolerant state machine replication (BFT SMR) protocol that combines strong robustness with high throughput, while attaining near-…
Shoal++: High Throughput DAG BFT Can Be Fast!
Balaji Arun, Zekun Li, Florian Suri-Payer +2
Today's practical partially synchronous Byzantine Fault Tolerant (BFT) consensus protocols trade off low latency and high throughput. On the one end, traditional BFT protocols such…
Zaptos: Towards Optimal Blockchain Latency
Zhuolun Xiang, Zekun Li, Balaji Arun +2
End-to-end blockchain latency has become a critical topic of interest in both academia and industry. However, while modern blockchain systems process transactions through multiple…
