The Honey Badger of BFT Protocols

Project description

Most fault tolerant protocols (including RAFT, PBFT, Zyzzyva, Q/U) don’t guarantee good performance when there are Byzantine faults. Even the so-called “robust” BFT protocols (like UpRight, RBFT, Prime, Spinning, and Stellar) have various hard-coded timeout parameters, and can only guarantee performance when the network behaves approximately as expected - hence they are best suited to well-controlled settings like corporate data centers.

HoneyBadgerBFT is fault tolerance for the wild wild wide-area-network. HoneyBadger nodes can even stay hidden behind anonymizing relays like Tor, and the purely-asynchronous protocol will make progress at whatever rate the network supports.
