[Hyperledger Project TSC] Research paper on BFT protocols for blockchain

Christian Cachin

As many of you are aware IBM's code contribution to Hyperledger at
contains an implementation of PBFT for consensus, which is part of
protocol "Sieve" that addresses non-determinism.

A technical paper describing the approach of "Sieve" and how to handle
non-deterministic transactions has just been made available at

For referencing it, please wait until this appears as a technical report on
arxiv.org -- we will inform the list again.
