原创 PlatON
隐私AI计算网络PlatON是面向未来的全球隐私计算网络，是全数字经济时代的公共基础设施。区块链生态的建设主要建立在智能合约之上，PlatON隐私计算基础设施，能够解决区块链生态发展的技术瓶颈，使链上匮乏的算力能够革命性的提升，使被传统互联网漠视的隐私保护能够得到有效的尊重，使不可信环境中的参与者能够可信的协同，真正成为数字经济的底层动能。
PlatON支持EVM和WASM两种智能合约,本教程主要介绍如何在PlatON私有链上部署solidity智能合约。
| 环境
系统：ubuntu18.04
搭建PlatON私有链，这里我们使用PlatON的单节点模式。
- 安装依赖
sudo apt update
sudo apt install -y golang-go git cmake llvm g++ libgmp-dev libssl-dev- 获取源码
git clone -b master https://github.com/PlatONnetwork/PlatON-Go.git --recursive- 编译
cd PlatON-Go
make all- 生成nodekey和blskey等相关文件
mkdir ./data && ./build/bin/platonkey genkeypair | tee >(grep "PrivateKey" | awk '{print $2}' > ./data/nodekey) >(grep "PublicKey" | awk '{print $3}' > ./data/nodeid) && ./build/bin/platonkey genblskeypair | tee >(grep "PrivateKey" | awk '{print $2}' > ./data/blskey) >(grep "PublicKey" | awk '{print $3}' > ./data/blspub)说明：
nodeid：节点公钥(ID）文件，保存节点的公钥，用于标识节点身份
nodekey：节点私钥文件，保存节点的私钥，不能公开并且需要做好备份。
blspub：节点BLS公钥文件，保存节点的BLS公钥，用于共识协议中快速验证签名。
blskey：节点BLS私钥文件，保存节点的BLS私钥，不能公开并且需要做好备份。- 创建keystore文件
./build/bin/platon --datadir ./data account new

}- 配置好创世文件后，就可以开始启动节点了
初始化创世区块
./build/bin/platon --datadir ./data init platon.json
后台启动节点
nohup ./build/bin/platon --identity "platon" --datadir ./data --port 6790 --rpcaddr 127.0.0.1 --rpcport 6789 --rpcapi "db,platon,net,web3,admin,personal" --rpc --nodiscover --nodekey ./data/nodekey --cbft.blskey ./data/blskey & > ./data/platon.log 2>&1 &私有链启动后就可以开始编辑合约了，这里使用alaya-truffle来编译，部署合约。
- 简单合约
pragma solidity ^0.5.17;
contract HelloWorld {
string name;
function setName(string memory _name) public returns(string memory){
name = _name;
return name;
}
function getName() public view returns(string memory){
return name;
}
}初始化工程：使用alaya-truffle初始化一个工程
mkdir HelloWorld && cd HelloWorld
alaya-truffle init在操作完成之后，就有如下项目结构：
contracts/: Solidity合约目录
migrations/: 部署脚本文件目录
test/: 测试脚本目录
truffle-config.js: alaya-truffle 配置文件将之前编写好的HelloWorld合约放至HelloWorld/contracts/目录下，并修改编译器版本
compilers: {
solc: {
version: "^0.5.17", // 此版本号与HelloWorld.sol中声明的版本号保持一致
}
}- 编译合约
alaya-truffle compile在操作完成之后，生成如下目录结构：
build/: Solidity合约编译后的目录
build/contracts/HelloWorld.json HelloWorld.sol对应的编译文件增加部署脚本文件并修改配置
cd migrations/ && touch initial_helloworld.js
添加以下内容到initial_helloworld.js
const helloWorld = artifacts.require("HelloWorld");
module.exports = function(deployer) {
deployer.deploy(helloWorld);
};
修改truffle-config.js中链的配置信息
networks: {
development: {
host: "127.0.0.1", // 区块链所在服务器主机
port: 6789 , // 链端口号
network_id: "*", // Any network (default: none)
from: "lat15cc8dhgzz9qsy9jyut5uqkjuvjt2r25qj0xx25 ", //部署合约账号的钱包地址
gas: 999999,
gasPrice: 50000000004,
},
}到此为止，就可以部署合约了，由于部署合约需要签名交易，所以需要先解锁钱包。
解锁钱包
alaya-truffle console
web3.platon.personal.unlockAccount('您的钱包地址','您的钱包密码',999999);- 部署合约
alaya-truffle migrate部署成功后，将看到类似如下信息：
initial_helloworld.js
