consensus-rs

Implement multiple blockchain consensus, including raft, pbft, paxos, dpos, power

• pbft
• raft
• paxos
• dpos
• power

start example

# git submodule add --force https://github.com/laohanlinux/parity-common.git

# ./build.sh

RUN Docker

docker build -t tt .

Debugging a Stuck Process

When the consensus node appears stuck (e.g. no new blocks), use these steps to find where it is blocked.

1. Enable trace logging

RUST_LOG=consensus=trace ./target/debug/consensus -c examples/c1.toml 2>&1 | tee /tmp/c1.log

Trace logs show seal wait cycles, commit events, and Core message handling. The last log line before the hang indicates where execution stopped.

2. Dump thread stack traces

When the process is stuck, from another terminal:

# Send SIGUSR2 to print debug hints
kill -USR2 $(pgrep -f "consensus.*c1")

# macOS: sample the process for 1 second to get stack traces of all threads
sample $(pgrep -f "consensus.*c1") 1

# Linux: use gdb to get backtraces
# gdb -p $(pgrep -f "consensus.*c1") -ex 'thread apply all bt' -ex quit

The sample output (macOS) or gdb output (Linux) shows each thread's call stack, so you can see which code path is blocking.
