这篇文档帮助开发人员了解如何加入PlasmaChain测试网进行部署。 如果你要找如何运行节点的信息，或者如何成为验证者，请查看验证者指南。

环境依赖

• 已安装Loom （查看 安装说明 ）

 curl https://raw.githubusercontent.com/loomnetwork/loom-sdk-documentation/master/scripts/get_loom.sh | sh

如何用Loom生成私钥并获得你的公共地址

$ ./loom genkey -k priv_key -a pub_key

结果

local address: 0x3B334bEd1e7d3e7d9214495120160D9236aCbC31
local address base64: OzNL7R59Pn2SFElRIBYNkjasvDE=

这将创建名为 priv_key 和 pub_key 的文件， priv_key 文件里包含你将用来把合同部署到DApp链的私钥。

# Deploy Truffle Example to a Testnet

1. Make sure you have node and yarn/npm installed

2. Obtain the testnet URL from PlasmaChain Testnets page

3. Get the source: bash git clone https://github.com/loomnetwork/truffle-dappchain-example cd truffle-dappchain-example # copy the private key generated earlier to the root directory of the example repo cp ../priv_key extdev_private_key

4. If you wish to deploy the example contracts to extdev-plasma-us1 skip this step. Otherwise, add the network you wish to deploy to in truffle-config.js.

5. Install node modules: bash yarn

6. Run deploy: bash yarn deploy:extdev
