如何运行Near节点并加入验证人

创建钱包账户

访问官方钱包网站https://wallet.betanet.near.org/create/ 来创建账户。

选择用户名：

选择备份方式：

备份助记词：

验证助记词：

创建完成：

安装工具

near-shell

near-shell是一款js编写的方便与near链交互的工具。

保证node的版本在10以上，可以采用npm来安装:

npm install -g near-shell

详细可参考: https://github.com/near/near-shell

nearup

nearup是用来管理near节点的python编写的工具, https://github.com/near/nearup

安装如下:

sudo apt update
sudo apt install python3 git curl
curl --proto '=https' --tlsv1.2 -sSfL https://up.near.dev | python3

登录账户

创建工作目录

mkdir stakewars && cd stakewars

在工作目录下，执行:

near login

会显示如下url:

Please authorize NEAR Shell on at least one of your accounts.

If your browser doesn't automatically open, please visit this URL
https://wallet.betanet.near.org/login/?title=NEAR+Shell&public_key=ed25519%xxxxxxxxxm&success
_url=http%3A%2F%2F127.0.0.1%3A5000

浏览器打开这个连接，然后用钱包授权访问，

之后将钱包的ID填入终端：

img/login1.png

这个会在相应目录下生成身份文件:

ls ~/.near-credentials/betanet/hashquarkdemo.betanet.json
/home/ubuntu/.near-credentials/betanet/hashquarkdemo.betanet.json

创建验证者账户

在工作目录里，采用如下命令创建验证者账户:

near create_account stakingPool_ID --masterAccount=account_ID

在我们的例子里可以采用(初始50NEAR):

near create_account pool.hashquarkdemo.betanet --masterAccount=hashquarkdemo.betanet --initialBalance 50

->

Using options: {
  masterAccount: 'hashquarkdemo.betanet',
  initialBalance: '50000000000000000000000000',
  networkId: 'betanet',
  nodeUrl: 'https://rpc.betanet.near.org',
  contractName: undefined,
  walletUrl: 'https://wallet.betanet.near.org',
  helperUrl: 'https://helper.betanet.near.org',
  helperAccount: 'betanet',
  useLedgerKey: "44'/397'/0'/0'/1'",
  newLedgerKey: "44'/397'/0'/0'/1'",
  accountId: 'pool.hashquarkdemo.betanet'
}
near create_account is deprecated and will be removed in version 0.26.0. Please use near create-account.
Account pool.hashquarkdemo.betanet for network "betanet" was created

在 ~~/.near-credentials/betanet/~ 可以看到新创建的pool的权限文件:

部署合约

编译

在工作目录下，下载合约仓库

git clone https://github.com/near/initial-contracts && cd initial-contracts/staking-pool

配置rustup添加target

rustup +stable target add wasm32-unknown-unknown

编译合约

./build.sh

启动节点

采用nearup的方式启动节点，默认会采用docker的方式安装，这也是比较方便的方式:

nearup betanet

如果不用docker，那么可以手动编译:

# 安装
cd ~ && git clone -b beta https://github.com/nearprotocol/nearcore.git && cd nearcore
git branch
make release

source $HOME/.nearup/env


# 相应的启动方式
nearup betanet --nodocker --binary-path ~/nearcore/target/release

启动后输入上面创建的验证者账户: pool.hashquarkdemo.betanet

查看日志: docker logs --follow nearcore

查看公钥:

cat ~/.near/betanet/validator_key.json |grep "public_key"

部署合约

部署刚刚编译好的wasm合约：

near deploy --accountId=pool.hashquarkdemo.betanet --wasmFile=initial-contracts/staking-pool/res/staking_pool.wasm

初始化

设置stake pool的owner_id，和费率：

near call pool.hashquarkdemo.betanet new '{"owner_id": "hashquarkdemo.betanet", "stake_public_key": "{上面输出的公钥}", "reward_fee_fraction": {"numerator": 10, "denominator": 100}}' --account_id hashquarkdemo.betanet

锁定合约

锁定的目的是防止合约变得，保护抵押者资金安全：

near delete-key --accessKey {上面输出的公钥} --accountId pool.hashquarkdemo.betanet

可以在浏览器上看到一个锁定的交易，图片为红色的叉叉状。

抵押

整体流程是先存款，再抵押：

# 存入20Near
near call pool.hashquarkdemo.betanet deposit '{}' --accountId hashquarkdemo.betanet --amount 20


# 抵押20Near,注意这的单位，得转化乘上1e24
near call pool.hashquarkdemo.betanet stake '{"amount": "2000000000000000000000000"}' --accountId hashquarkdemo.betanet
