Colordag: An Incentive-Compatible Blockchain
Ittai Abraham, Danny Dolev, Ittay Eyal +1
We present Colordag, a blockchain protocol where following the prescribed strategy is, with high probability, a best response as long as all miners have less than 1/2 of the mining…
Fever: Optimal Responsive View Synchronisation
Andrew Lewis-Pye, Ittai Abraham
View synchronisation is an important component of many modern Byzantine Fault Tolerant State Machine Replication (SMR) systems in the partial synchrony model. Roughly, the efficien…
BeeGees: stayin' alive in chained BFT
Ittai Abraham, Natacha Crooks, Neil Giridharan +2
Modern chained Byzantine Fault Tolerant (BFT) systems leverage a combination of pipelining and leader rotation to obtain both efficiency and fairness. These protocols, however, req…
Good-case and Bad-case Latency of Unauthenticated Byzantine Broadcast: A Complete Categorization
Ittai Abraham, Ling Ren, Zhuolun Xiang
This paper studies the {\em good-case latency} of {\em unauthenticated} Byzantine fault-tolerant broadcast, which measures the time it takes for all non-faulty parties to commit gi…
Reaching Consensus for Asynchronous Distributed Key Generation
Ittai Abraham, Philipp Jovanovic, Mary Maller +3
We give a protocol for Asynchronous Distributed Key Generation (A-DKG) that is optimally resilient (can withstand faulty parties), has a constant expected number of…
Brief Note: Fast Authenticated Byzantine Consensus
Ittai Abraham, Kartik Nayak, Ling Ren +1
Byzantine fault-tolerant (BFT) state machine replication (SMR) has been studied for over 30 years. Recently it has received more attention due to its application in permissioned bl…
