Prototype Implementation of a Practical Partially Synchronous DKG

This repository contains a prototype implementation of a practical distributed key generation system with two execution modes:

• async: asynchronous DKG
• psync: partially synchronous DKG

Credits

This code builds on components from the following repositories:

• VSS: https://github.com/sourav1547/e2e-vss
• ACS: https://github.com/akhilsb/acss-rs/tree/master/consensus/acs
• Partially synchronous consensus: https://github.com/asonnino/hotstuff

Run Locally

Requirements

The local runner expects:

• Rust and Cargo
• tmux
• lsof
• python3

Commands

Use the runner script at the repo root:

./run_dkg.sh 4 async

This starts a 4-node asynchronous DKG run locally.

./run_dkg.sh 4 psync

This starts a 4-node partially synchronous DKG run locally.

What the Script Does

run_dkg.sh:

• regenerates local node configs
• generates latency input from the files in config-files/
• starts one tmux session per node
• runs the cli binary for each node

Useful Notes

• Attach to node 0 with:

tmux attach -t cli_node0

• The default node count is 4 if omitted.
• The default latency profile is raw.
• Generated configs are written under tmpconfig/.
