In this post, we will give a brief introduction to reliable broadcast and how we use it in Topos. The first thing to mention about reliable broadcast is that it can be implemented in the asynchronous model, meaning that the correctness of the algorithm is independent of any timing assumptions…

Cryptography is at the heart of any blockchain project. A good deal of their useful properties (immutability, security, public verifiability…) comes from cryptographic protocols, which themselves rely on common and well-studied mathematical problems. Among them, Toposware uses its very own digital signature scheme to verify the authenticity of certificates —…

We’re extremely excited to announce the release of a bunch of innovations we’ve been working on for the past two years!
