zebclock

Overview

The zebclock is a implement of vlc(verifiable logical clock) and the zebclock is one module of zeb network.

It use the zeb p2p relay as network module. And as a backend project node for supporting verifiable logical clock and causality ordering. This system is currently in poc stage.

Dependences

PostgreDB

The zebclock depends on postgre db for data persistence, so please install postgre and setup a pg instance.

Zeb p2p relayer

The zebclock play a role of inner logic and state layer in vlc overview. One zebclock process matches a zeb p2p node, and them use inner net socket for communication.

For now, zebclock and zeb use the same node identity for two processes. So first generate a key pair identity, then address it to node_id in config-template.yaml of zebclock.

Net messaging

The zebclock and zeb using protobuf proto3 as serialization compression algorithm and communication protocol. More messages body details, please see crates/protos for check it.
