Follow up work accepted to DISC: multi-valued asynchronous byzantine agreement with perfect security and optimal resilience given binary ABA in O(nL+n^2 log n)

In fact you can get the optimal 5f-1 (or more generally 3f+2p-1)

Decentralized thoughts on graded dispersal with perfect security and its applications With Gilad Asharov and Anirudh Chandramouli

Looking forward to speak at the Science and Engineering of Consensus workshop on Sunday in Berkeley. I'll talk about recent work with @kartik1507 and @nibeshrestha2 on our "Pipes" model for analysing blockchain protocols. One of the advantages of the model is that it actually allows to compare max throughput for different protocols...

Applications are invited for postdoc positions in my group @TelAvivUni. The selected candidates will confront challenging problems in graph algorithms (dynamic, distributed, geometric). A "remote" option may also be possible. Help me spread the word!
