Walrus: An Efficient Decentralized Storage Network
George Danezis, Giacomo Giuliari, Eleftherios Kokoris Kogias +5
Decentralized storage faces a fundamental trade-off between replication overhead, recovery efficiency, and security guarantees. Current approaches either rely on full replication,…
Byzantine Consensus in the Random Asynchronous Model
George Danezis, Jovan Komatovic, Lefteris Kokoris-Kogias +2
We propose a novel relaxation of the classic asynchronous network model, called the random asynchronous model, which removes adversarial message scheduling while preserving unbound…
Obelia: Scaling DAG-Based Blockchains to Hundreds of Validators
George Danezis, Lefteris Kokoris-Kogias, Alberto Sonnino +1
Obelia improves upon structured DAG-based consensus protocols used in proof-of-stake systems, allowing them to effectively scale to accommodate hundreds of validators. Obelia imple…
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…
