Foundry Build Status chat License: GPL v3

CodeChain Foundry is a blockchain engine based on a composable module system called Mold. Users can write their own modules in addition to bringing in those written by others in order to construct an arbitrary blockchain application. The reason why we provide such a composable and user-configurable module system is because we want to make as much of the application configurable as possible and foster an ecosystem of reusable modules, while reusing the underlying consensus engine across all the different kinds of applications.

Upon execution of a transaction that is essentially a state transition, the coordinator will be told to execute the transaction from the underlying consensus engine. Then the coordinator literally coordinates multiple modules constituting an application by invoking services exported by the modules to the coordinator in an appropriate order passing appropriate arguments. Transactions will be delivered to the responsible modules, and those modules will handle the executions of the transactions, which might also involve communications with other modules.

Build

Download Foundry code

git clone git@github.com:CodeChain-io/foundry.git
cd foundry

Build in release mode

cargo build --release

This will produce an executable in the ./target/release directory.

Building From Source

Build Dependencies

Foundry requires Rust version 1.47.0 to build. Using rustup is recommended.

  • For Linux Systems:

    • Ubuntu

      gcc, g++ and make are required for installing packages.

      $ curl https://sh.rustup.rs -sSf | sh
  • For Mac Systems:

    • MacOS 10.13.2 (17C88) tested

      clang is required for installing packages.

      $ curl https://sh.rustup.rs -sSf | sh
  • For Windows Systems:

    • Currently not supported for Windows. If on a Windows system, please install WSL to continue as Ubuntu.

Please make sure that all of the binaries above are included in your PATH. These conditions must be fulfilled before building Foundry from source.

Download Foundry's source code and go into its directory.

git clone git@github.com:CodeChain-io/foundry.git
cd foundry

Build as Release Version

cargo build --release

This will produce an executable in the ./target/release directory.

Formatting

Make sure you run rustfmt before creating a PR to the repo. You need to install the nightly-2020-10-20 version of rustfmt.

rustup toolchain install nightly-2020-10-20
rustup component add rustfmt --toolchain nightly-2020-10-20

To run rustfmt,

cargo +nightly-2020-10-20 fmt

Linting

You should run clippy also. This is a lint tool for rust. It suggests more efficient/readable code. You can see the clippy document for more information. You need to install the stable version of clippy.

Install

rustup component add clippy

Run

cargo clippy --all --all-targets

Testing

Run cargo test --all for unit tests. See /integration-test/README.md for integration tests.
