1. Description

This repository contains the pre-alpha version prototype implementation of Crypto.com Chain. The current repository consists of the following Rust sub-crates:

• chain-abci: the Tendermint ABCI application that currently does the transaction validation etc.

• chain-core: the library that contains the main type definitions and any utility code (such as serialization), so that it can be used in chain-abci and other applications.

• dev-utils: currently a minimal development tool for generating genesis.json

• client-[common|index|core|rpc]: Client backend implementation for transaction creation and wallet management. Follow these links for more details:

  • client-common
  • client-core
  • client-rpc

5. Build

5.1. Build Prerequisites

Crypto.com chain requires the following to be installed before build.

• Homebrew
• Tendermint
• Rust and Cargo (cargo version: 1.36 onwards)
• cmake

  $ brew install cmake

• ZeroMQ

  $ brew install zmq

• pkg-config

  $ brew install pkg-config

After all dependencies are installed, add the following lines to ~/.cargo/config to enable generating instructions for Streaming SIMD Extensions 3 and Advanced Vector Extensions on build:

[build]
rustflags = ["-Ctarget-feature=+aes,+sse2,+sse4.1,+ssse3"]

(TODO: In the future, the build tooling may be migrated to Bazel / Nix etc. for reproducible builds.)

5.2. Build Instructions

$ git clone [email protected]:crypto-com/chain.git
$ cd chain

$ cargo build

The built executables will be put inside folder /target/debug/ by default.

6. Start a Local Full Node

Please follow the instruction to deploy a local full node.

7. Send Your First Transaction

Kindly refer to this instruction to perform transactions between addresses.

8. Testing

To run the test cases

$ cargo test

To measure code coverage by cargo-tarpaulin:

$ cargo tarpaulin

This only works on x86_64 processors running Linux. On different platforms, you will need to use Docker:

$ docker run --security-opt seccomp=unconfined -v "$PWD:/volume" xd009642/tarpaulin
