About
BRB is a Byzantine Fault Tolerant (BFT) system for achieving network agreement over eventually consistent data-type algorithms such as CRDTs.
For an overview how BRB works, please see these slides. (pdf | odp).
This crate and its related crates (brb_*) implement a loosely-coupled Byzantine Fault Tolerant (BFT) system for achieving network agreement over eventually consistent data-type algorithms such as CRDTs.
BRB Crates
As of this writing, the crates are:
| crate | description |
|---|---|
| brb | this crate. provides BRB implementation and BRBDataType trait that brb_dt_* crates implement |
| brb_membership | BRB dynamic membership: support for peers joining and leaving a BRB group |
| brb_dt_at2 | An implementation of the AT2 algorithm in a BRB DataType wrapper |
| brb_dt_orswot | A BRB DataType wrapper for the Orswot CRDT algorithm in rust-crdt |
| brb_dt_tree | A BRB DataType wrapper for the Tree CRDT algorithm in crdt_tree |
| brb_node_qp2p | Interactive P2P node (CLI) for using BRB over Quic protocol via qp2p |
Each brb_dt_* crate provides a particular data-type with its own operations that are wrapped in such a way that it can be transferred via BRB. At present AT2 and CRDT data types are well suited for this. We intend to wrap many such data types, with each wrapper in its own crate.
Traits
