Description

Yeebranch is designed as layer 2 of YeeCo.

Layer	Name	Consensus	Transaction types
1	Yeeroot chain	POW for block generation CRFG for block finalization	Native coin tx Token tx Meta tx of branch chains
2	Yeebranch chain	Optional DPOS POA	Basic tx Smart contract tx

Install

Requirements

1. Rust

   curl https://sh.rustup.rs -sSf | sh

2. Openssl
3. Rust nightly

   rustup toolchain add nightly

4. rust nightly wasm

   rustup target add wasm32-unknown-unknown
   rustup target add wasm32-unknown-unknown --toolchain nightly

5. wasm-gc

   cargo install wasm-gc

6. Rust components: clippy rls docs src rustfmt

   rustup component list # list all the components installed
   rustup component add <name> # install component

Prepare yeeroot chain resources

Yeebranch runs a light node of yeeroot chain internally, so it needs the following resources of the yeeroot chain:

• Runtime WASM

  After you build yeeroot project, You will get the Runtime WASM on <yeeroot_project_base_dir>/runtime/wasm/target/wasm32-unknown-unknown/release/yee_runtime_wasm.compact.wasm

• Chain spec

  Run build-spec to export chain spec file:

  $ yee build-spec --dev > root_chain_sepc.json

Building

$ cd <project_base_dir>/runtime/wasm
$ sh build.sh
$ cd <project_base_dir>
$ WASM_CODE_PATH=<yeeroot_project_base_dir>/runtime/wasm/target/wasm32-unknown-unknown/release/yee_runtime_wasm.compact.wasm cargo build

Usage

Start

1. Deploy yeeroot chain sepc

   $ mkdir -p <yeebranch_run_base_path>/conf
   $ cp root_chain_sepc.json <yeebranch_run_base_path>/conf

   <yeebranch_run_base_path> is: ~/Library/Application\ Support/YeeBranch/ or the one you specify by ./yee-branch --base-path=<yeebranch_run_base_path>,

2. Start the node

   $ ./yee-branch --base-path=<yeebranch_run_base_path> --dev --alice
