Move Node

A new RML-based substrate and libra move engine.

Building

Install Rust:

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

Install required tools:

./scripts/init.sh

Developing environment: In linux and mac: ref
In Windows : ref

Build all native code:

cargo build

Run

You can start a development chain with:

cargo run -- --dev --other-execution=Native --syncing-execution=Native --block-construction-execution=Native --importing-execution=Native

Move

You can execute your move program like in the Libra chain. Basic function is transfer coin, high grade function is deploy custom program. Here is some demo how to do it.

We also provide a caster tool that makes it easy for users to call the move function.

Demo

Goto caster directory.

cd caster

sudo account:

Mint

cargo run -- tx -m mint -k 0x4db4ef1992889d4428e400be3428843db6e89bb2e8aaf4ce8efe00df64012544 -r 0x44416e28b8545d375a212c44d9719e5c21c4f44123be4993768c899bf3c02826 -v 10000 -s 0

A move script will be created after execution. use Substrate explorer to execute script.

At Chain State page, you can see the new account balance.

Transfer

cargo run -- tx -m transfer -k 0x4db4ef1992889d4428e400be3428843db6e89bb2e8aaf4ce8efe00df64012544 -r 0xb2c5ac79fdc6f4b8159a0500104ec59c99c5413a52423bfb2d23bc43290c6907 -v 100 -s 0

use Substrate explorer to execute script.

At Chain State page, you can see the new account balance.

Publish Custom Module

Write your move module.

module M {
	public max(a: u64, b: u64): u64 {
		if (copy(a) > copy(b)) {
			return copy(a);
		} else {
			return copy(b);
		}
		return 0;
	}

	public sum(a: u64, b: u64): u64 {
		let c: u64;
		c = copy(a) + copy(b);
		return copy(c);
	}
}

To build module

cargo run -- tx -k 0x4db4ef1992889d4428e400be3428843db6e89bb2e8aaf4ce8efe00df64012544 -m publish --compiled_file ./scripts/m.mvir -s 1

use Substrate explorer to execute script.

Call Custom Module

Write your move script to call module.

import 0x0.LibraAccount;
import 0x44416e28b8545d375a212c44d9719e5c21c4f44123be4993768c899bf3c02826.M;

main() {
	let a: u64;
	let b: u64;
	let amount: u64;
    let payee:address;

	a = 10;
	b = 2;
	amount = M.sum(copy(a), copy(b));
    payee = 0x1;

    LibraAccount.pay_from_sender(move(payee), move(amount));
    return;
}

cargo run -- tx -k 0x4db4ef1992889d4428e400be3428843db6e89bb2e8aaf4ce8efe00df64012544 -m publish --compiled_file ./scripts/s.mvir -s 2

use Substrate explorer to execute script.

Roadmap

• In August 2019, the Substrate-based Ethereum Bridge and move smart contract design were completed. Completed BOOL NETWORK architecture design.

• In September 2019, the Ethereum Bridge and Native Move Runtime were developed based on Substrate.

• In October 2019, implement WASM Move Runtime.

• In November 2019, implement a system like MakerDao based on the Move language.

• In December 2019, design and implement a decentralized trading engine based on Substrate, BOOL MAIN NETWORK will be online.
