Substrate with PBFT

This repo implement PBFT and Tendermint as alternatives to GRANDPA.

Usage

1. Setup Rust. Add nightly toolchain and wasm target.
2. Clone repos. (Under the same folder)

git clone https://github.com/fky2015/finality-tendermint.git
git clone https://github.com/fky2015/finality-pbft.git
git clone https://github.com/fky2015/substrate-with-pBFT-and-tendermint.git

NOTE: To build cargo b --bin node-template, you need finality-pbft & substrate-with-pBFT-and-tendermint. To build cargo b --bin node-tendermint, you need finality-tendermint & substrate-with-pBFT-and-tendermint.

Place them under the same directory.

3. Build.

cd substrate-with-pBFT-and-tendermint
# build PBFT node
cargo build -p node-template
# build Tendermint node
cargo build -p node-tendermint

4. Run node.

./target/debug/node-template --dev --tmp
# or
./target/debug/node-tendermint --dev --tmp

Test script

Test scripts are in the ./pbft-test-scripts/ and ./tendermint-test-scripts/. Run from project root dir such as bash ./pbft-test-scripts/single.sh.

Info

There is a substrate-contracts-node campatible version substrate-contracts-node-with-pBFT.

This is campatible to Substrate May 12th, 2022.

Contributions & Code of Conduct

Please follow the contributions guidelines as outlined in docs/CONTRIBUTING.adoc. In all communications and contributions, this project follows the Contributor Covenant Code of Conduct.

Security

License

• Substrate Primitives (sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0.
• Substrate Client (/client/* / sc-*) is licensed under GPL v3.0 with a classpath linking exception.

The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.

In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
