## Validator

- Create validator wallet(validator's identity)
```shell
opera account new
# Enter wallet password
```
- Fund wallet 200,000$VS +
- Create a new Validator key
```shell
opera validator new
# Enter validator key password
```
- Create validator
```shell
# attach opera console
opera attach

# initialize the SFC contract ABI variable
(https://github.com/VinuChain/VinuChain):
abi = JSON.parse
(https://pastebin.com/sbDq7T92)
abi = JSON.parse("[{\"anonym…able\",\"type\":\"function\"}]")

# initialize the SFC contract object itself
sfcc = web3.vc.contract(abi).at("0xfc00face00000000000000000000000000000000")

// Sanity check
sfcc.lastValidatorID() 
// if everything is all right, will return a non-zero value

# Get your validator id
sfcc.getValidatorID("VALIDATOR_WALLET_ADDRESS")

# Unlock validator wallet
personal.unlockAccount("VALIDATOR_WALLET_ADDRESS", "PASSWORD", 300)

```
- Register validator
```shell
# Register your validator
tx = sfcc.createValidator("0xYOUR_PUBKEY", {from:"0xYOUR_WALLET_ADDRESS", value:
web3.toWei("200000.0", "vc")}) // 200000.0 VC

# Check your registration transaction
vc.getTransactionReceipt(tx)

# Get your validator id
sfcc.getValidatorID("VALIDATOR_WALLET_ADDRESS")
```

- Run validator node

```shell
# stop the opera process
pkill opera
sudo killall opera

## <Create an empty file and paste validator node password into it.>

# mainnet
nohup ./opera 
--bootnodes enode://105ecea3fafaa01a329b9ce988d69ad7d9af233b04ad2c3b637b2f42862623c38f358bd7a7cfead5ae61991681965629abe2749131168bdd9ce573f8085380ab@node-0.vinuchain-rpc.com:3000
--validator.id ID 
--validator.pubkey VALIDATOR_PUBKEY 
--validator.password PATH_TO_PASSWORDFILE > validator.log &

# testnet
nohup ./opera 
--bootnodes enode://c7e3e7ab29d1ee7693a11d1a6d019db543f71c428b0f323f082e9d13d10cc2d6cc11cdb1dd27e21746afeb0c48435d0f55ad01c2b89162fdac0d0f7c2f4744d0@54.203.151.219:3000 
--validator.id ID 
--validator.pubkey VALIDATOR_PUBKEY 
--validator.password PATH_TO_PASSWORDFILE > validator.log &
```
## 更新 Validator 节点信息

- Host the config file somewhere publicly accessible
```json
{  
  "name": "VALIDATOR_NAME", /* Name of the validator */
  "logoUrl": "LOGO_URL", /* Validator logo (PNG|JPEG|SVG) - 100px x 100px is enough */
  "website": "WEBSITE_URL", /* Website icon on the right */
  "contact": "CONTACT_URL" /* Contact icon on the right */
}
```
- Open up a go-opera console session
```shell
opera attach
```
- Load the `stakerInfoContract` ABI and instantiate the contract
```js
abi = JSON.parse('[{"inputs":[{"internalType":"address","name":"_stakerContractAddress","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":false,"internalType":"uint256","name":"stakerID","type":"uint256"}],"name":"InfoUpdated","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"internalType":"address","name":"previousOwner","type":"address"},{"indexed":true,"internalType":"address","name":"newOwner","type":"address"}],"name":"OwnershipTransferred","type":"event"},{"constant":true,"inputs":[],"name":"isOwner","outputs":[{"internalType":"bool","name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"internalType":"address","name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"renounceOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"internalType":"uint256","name":"","type":"uint256"}],"name":"stakerInfos","outputs":[{"internalType":"string","name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"internalType":"address","name":"newOwner","type":"address"}],"name":"transferOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"internalType":"address","name":"_stakerContractAddress","type":"address"}],"name":"updateStakerContractAddress","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"internalType":"string","name":"_configUrl","type":"string"}],"name":"updateInfo","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"internalType":"uint256","name":"_stakerID","type":"uint256"}],"name":"getInfo","outputs":[{"internalType":"string","name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}]')

# mainnet
stakerInfoContract = web3.vc.contract(abi).at("0xb914a0b16111BaB228ae6214e6E1FD4a5EaE877C")
# testnet
stakerInfoContract = web3.vc.contract(abi).at("0x6b39bcd174DddF5A17d065822BDC43353eB6112A")
```
- Call the updateInfo function of the stakerInfoContract (make sure you have enough VC on your wallet to cover the transaction fee)
```js
# Unlock validator wallet
personal.unlockAccount("VALIDATOR_WALLET_ADDRESS", "PASSWORD", 300)
# 
stakerInfoContract.updateInfo("CONFIG_URL", 
{ from: "VALIDATOR_WALLET_ADDRESS" })
# Validate if you updated your info correctly
stakerInfoContract.getInfo(STAKER_ID)
```
