In this series of posts, we explore what can be done in the Asynchronous model. This model seems challenging because the adversary can delay messages by any bounded time. By the end of this series, you will see that almost everything that can be done in synchrony can be obtained...| decentralizedthoughts.github.io
In this series of posts, we explore the marvelous world of consensus in the Asynchronous model. In this post, we start by simply defining the problem. Recall the FLP theorem: FLP theorem 1985: Any protocol where no two non-faulty parties decide different values in the asynchronous model that is resilient...| decentralizedthoughts.github.io
We extend the Gather protocol with two important properties: Binding and Verifiability. This post is based on and somewhat simplifies the information theoretic gather protocol in our recent ACS work with Gilad Asharov and Arpita Patra. Recall that we are in an asynchronous model, assuming $f<n/3$, with at most $f$...| decentralizedthoughts.github.io
