Sui Lutris: A Blockchain Combining Broadcast and Consensus
Sam Blackshear, Andrey Chursin, George Danezis +9
Sui Lutris is the first smart-contract platform to sustainably achieve sub-second finality. It achieves this significant decrease by employing consensusless agreement not only for…
Mysticeti: Reaching the Limits of Latency with Uncertified DAGs
Kushal Babel, Andrey Chursin, George Danezis +5
We introduce Mysticeti-C, the first DAG-based Byzantine consensus protocol to achieve the lower bounds of latency of 3 message rounds. Since Mysticeti-C is built over DAGs it also…
Cuttlefish: Expressive Fast Path Blockchains with FastUnlock
Lefteris Kokoris-Kogias, Alberto Sonnino, George Danezis
Cuttlefish addresses several limitations of existing consensus-less and consensus-minimized decentralized ledgers, including restricted programmability and the risk of deadlocked a…
HammerHead: Leader Reputation for Dynamic Scheduling
Giorgos Tsimos, Anastasios Kichidis, Alberto Sonnino +1
The need for high throughput and censorship resistance in blockchain technology has led to research on DAG-based consensus. The Sui blockchain protocol uses a variant of the Bullsh…
Securing Consensus from Long-Range Attacks through Collaboration
Junchao Chen, Suyash Gupta, Alberto Sonnino +2
Decentralized systems built around blockchain technology promise clients an immutable ledger. They add a transaction to the ledger after it undergoes consensus among the replicas t…
Performance of EdDSA and BLS Signatures in Committee-Based Consensus
Zhuolun Li, Alberto Sonnino, Philipp Jovanovic
We present the first performance comparison of EdDSA and BLS signatures in committee-based consensus protocols through large-scale geo-distributed benchmarks. Contrary to popular b…
