跨链获取价格

使用cumulus进行跨链不同托盘测试

编译启动中继链

## 编译

git clone -b release-v0.9.9 https://github.com/paritytech/polkadot

cd polkadot

cargo build --release

##导出链配置文件

./target/release/polkadot build-spec --chain=rococo-local --disable-default-bootnode --raw > rococo-local.json

##运行两个节点

./target/release/polkadot --name alice --chain rococo-local --alice -d ./data/alice --ws-external --rpc-external --rpc-cors all  --node-key 0000000000000000000000000000000000000000000000000000000000000001

./target/release/polkadot --name bob --chain rococo-local --bob -d ./data/bob --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp

下载跨托盘测试代码

git clone https://github.com/aresprotocols/mars.git

git checkout bridge

编译

#编译

cd mars

cargo build 

#导出genesis state和wasm文件

./target/debug/polkadot-collator export-genesis-wasm > genesis-wasm

./target/debug/polkadot-collator export-genesis-state --parachain-id 2000 > genesis-state-2000

./target/debug/polkadot-collator export-genesis-state --parachain-id 2001 > genesis-state-2001
