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…
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…
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…
Efficient Multiparty Protocols Using Generalized Parseval's Identity and the Theta Algebra
Giorgio Sonnino, Alberto Sonnino
We propose a protocol able to show publicly addition and multiplication on secretly shared values. To this aim we developed a protocol based on the use of masks and on the FMPC (Fo…
Zef: Low-latency, Scalable, Private Payments
Mathieu Baudet, Alberto Sonnino, Mahimna Kelkar +1
We introduce Zef, the first Byzantine-Fault Tolerant (BFT) protocol to support payments in anonymous digital coins at arbitrary scale. Zef follows the communication and security mo…
