Bullshark: The Partially Synchronous Version
Alexander Spiegelman, Neil Giridharan, Alberto Sonnino +1
The purpose of this manuscript is to describe the deterministic partially synchronous version of Bullshark in a simple and clean way. This result is published in CCS 2022, however,…
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…
Low-latency, Scalable, DeFi with Zef
Mathieu Baudet, Alberto Sonnino, Michal Krol
Zef was recently proposed to extend the low-latency, Byzantine-Fault Tolerant (BFT) payment protocol FastPay with anonymous coins. This report explores further extensions of FastPa…
Bullshark: DAG BFT Protocols Made Practical
Alexander Spiegelman, Neil Giridharan, Alberto Sonnino +1
We present Bullshark, the first directed acyclic graph (DAG) based asynchronous Byzantine Atomic Broadcast protocol that is optimized for the common synchronous case. Like previous…
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…
