PrestigeBFT: Revolutionizing View Changes in BFT Consensus Algorithms with Reputation Mechanisms

Update Heads-up

A major update of the code will be posted in August, which incorporates a more efficient communication service between clients and servers and among servers.

Run PrestigeBFT

GoLang should have been properly installed with GOPATH and GOROOT. The GoLang version should be at least go1.17.6. In addition, three external packages were used (check out go.mod).

// threshold signatures
go get go.dedis.ch/kyber
// logging
go get github.com/sirupsen/logrus
// some math packages
go get gonum.org/v1/gonum/

At this stage, we would like to introduce the key parameters in PrestigeBFT.

-b int is the batch size
-mq int is the maximum size of message queues
-p int is the number of packing threads used in one consensus instance
-pt int is the number of computing threads used in view changes

-n int is the number of servers in total (system configuration)
-th int is the threshold value for threshold signatures (quorums)
-id int is this server's ID
-d int is the emulated network delay

-ns bool enables native storage for storing committed entries in plain text files
-r bool enables log responsiveness
-gc bool enables deleting cache entries that have been committed by consensus
-repu bool enables the reputation engine with computing hash computaional work

-s int inital server state: 0 : Leader; 1 : Nominee; 2 : Starlet; 3 : Worker
-rp bool prints real time log on the screen
perf enables peak prformance testing configuration, which disables rp and gc
