truechain-consensus-core

TrueChain Consensus Protocol

Building the source

Build

Step 1

Install Docker and HyperMake.

Make sure you have hmake in your $GOBIN path.

Building it all with hmake and docker

This project uses:

• HyperMake to interact with toolchain (containerized environment) and build cross-platform binaries.
• gvt to manage dependencies.

$ hmake --targets
$ hmake check
$ hmake build

The first time, it would download:

• TrueChain's docker image go-toolchain from https://hub.docker.com/r/truechain/go-toolchain/
• Dependencies as per src/vendor/manifest, which again, could be generated using gvt.

The binaries would be available in bin/'s platform-specific folders.

Step 2

git clone https://github.com/truechain/truechain-consensus-core.git
cd truechain-consensus-core
git checkout devel

OR

go get -u github.com/truechain/truechain-consensus-core

Step 3

Make sure you have $GOBIN in $PATH:

export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN

And before running, make sure you have the following taken care of, for orchestration:

1. TRUE_TUNABLES_CONF corresponds to /etc/truechain/tunables_bft.yaml, default's under project's config/ folder.

2. TRUE_GENERAL_CONF corresponds to /etc/truechain/logistics_bft.cfg, default's under this project's config/

3. TRUE_NETWORK_CONF corresponds to /etc/truechain/hosts, Default's under this project's config/ This file is populated with repetitive 5-6 lines containing loopback IP address 127.0.0.1.

4. TRUE_SIMULATION is as follows:

• if set to 0 (default) - should tell the project to pickup testbed configurations.
• if set to 1 - staging, meaning all CI/CD tests are run before draft run. (dummy functionality at the moment)
• if set to 1 - production. Will try to connect to boot nodes. (dummy functionality at the moment)

Run

Server:

./bin/{linux/darwin}/truechain-engine

Client:

$ ./bin/{linux/darwin}/pbft-client -h

Usage of pbft-client:
  -numquest int
    	number of requests (default 10)

Optional - To install:

./support/scripts/install.sh linux
# then from 1 shell, run
$ truechain-engine
# and a different shell, run
$ pbft-client -numquest 40

This triggers both server and client subroutines. Also displays progress of key signing, data exchange and ledger log.

CI

hmake build test check

TODO: add travis yaml

managing a missing dependency

In case you have a new dependency that's not listed in trueconsensus/vendor/manifest folder, just run this from trueconsensus/:

gvt fetch github.com/fatih/color

This would add a folder trueconsensus/vendor if not already present, and would also generate/append to trueconsensus/vendor/manifest.

Note that gvt fetch <package_name> updates the file src/vendor/manifest.

Building it all with a shell script

Additionally, you could choose to build without using containers. For a very basic sanity test, run the following:

./support/scripts/build.sh {linux/darwin}

Note: you could also use darwin as an argument to build.sh instead of linux to get an OSX binary. Support for more will be extended soon.

Deployment

To be added.

Benchmark

To be added.

Feedback

Feedback is greatly appreciated. We're a blend of py-go-c++ devs looking to merge ideas and we may err at times in the realm of language paradigms and correct design approach. We're hoping to find you (yes you!) and incentivize you for auditing our codebase, polish the erm out of it and teach us how to fish in this process. Feel free to open issues / contact us on our channels.

Contributing

We need contributions from you. You are welcome to create github issues and contribute to the codebase. We have a list of important tasks from Truechain Foundation. We welcome people who have related background to join our consensus design and implementation.

The maintainers actively manage the issues list, and try to highlight issues suitable for newcomers. The project follows the typical GitHub pull request model. See CONTRIBUTIONS.md for more details. Before starting any work, please either comment on an existing issue, or file a new one.
