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

Christian Cachin <cca@...>

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.
