LibraChain

A library providing mechanized proofs of the LibraBFT consensus using the Coq theorem prover.

Architecture & Evolution

This library uses the SSreflect proof language and mathematical components libraries for Coq.

It is compatible with, inspired by, and extends, the ToyChain library by George Pirlea, Ilya Sergey et al.

This library is at an experimental stage and its contents may know significant evolutions in the future.
