# Install Validator Node ## Validator Parameters * Minimum Staking Size: 
200,000 VC
* Maximum Validator Size: ``` 15x the self-stake amount ``` * Minimum Hardware Requirements: ``` m6i.large or better (2 vCPUs, 8GB RAM), 200GB SSD ``` * Unlock Period: ``` 3 days from when you undelegate (bonding time). ``` * Rewards: ``` Block rewards from self-stake + 15% of delegators' rewards. APY varies based on staked %. ``` ## Validators After installing a [Read-Only Node](/vinuchain/technical-docs/vinuchain-mainnet/read-only-node.md), you can upgrade to a VinuChain validator by registering your validator node on-chain. To do this, you need to have at least 200,000 VC to create a validator wallet. The wallet is the validator’s identity in the network which it uses to authenticate, sign messages, etc. A validator is a network participant responsible for confirming and validating transactions, producing new blocks, and securing the network's consensus protocol. Validators play a critical role in maintaining the integrity and security of the VinuChain blockchain. ***Validators receive block rewards for their contribution to the network.*** ***If you have not installed your*** [***Read-Only Node***](/vinuchain/technical-docs/vinuchain-mainnet/read-only-node.md) ***yet, please begin at the previous page!*** ## Create a validator wallet The node is now running and syncing the network in your current console, so you need to open up a new console window, connect via **SSH** to the server and enter the following commands to **create a validator wallet:** ``` # Create validator wallet (validator)$ ./opera account new ``` After entering the command, you will get prompted to enter a password for the account (= wallet) — use a strong one! You can e.g. use a password manager to generate a 20+ digit password to secure your wallet. It will look something like this:
NEVER share your private key or keystore with anyone! ### **Fund your validator wallet** The next step is to fund your validator wallet with enough VC to become a validator. That means you need to have at least **200,000 VC** in the wallet you just created (send a little more to cover transaction fees). After successfully sending the VC to your newly created Opera wallet, you can **register your validator via the SFC Smart Contract.** Make sure you wait for your node to be fully synced, otherwise your VC will not show up in your wallet! ## Create a new validator key We have to create validator private key to sign consensus messages with. It can be done only using **go-opera** ``` (validator)$ ./opera validator new ```
Follow the prompts and supply the password, the output is as follows: ``` Your new key was generated Public key: 0xPubkey Path of the secret key file: - You can share your public key with anyone. Others need it to validate messages from you. - You must NEVER share the secret key with anyone! The key controls access to your validator! - You must BACKUP your key file! Without the key, it's impossible to operate the validator! - You must REMEMBER your password! Without the password, it's impossible to decrypt the key! ``` ## Create your validator via the SFC You should wait for your node to sync to the latest block of the network before proceeding. ### Attach to Opera console To proceed, open up the console where you entered the commands to create the validator wallet previously and attach to the Opera node console: ``` # Attach to opera console (validator)$ ./opera attach ``` By doing so, you will get a JavaScript console where you can directly interact with the Opera node and e.g. send transactions (which you will do in a moment):

``` and **initialize the SFC contract object itself**: ``` sfcc = web3.vc.contract(abi).at("0xfc00face00000000000000000000000000000000") ``` After initializing both variables, you can now interact with the network’s SFC. ### Sanity check Enter the following command to check that everything works as expected: ``` // Sanity check sfcc.lastValidatorID() // if everything is all right, will return a non-zero value ``` If it looks like this, everything is OK (you should not get an error here):
### Get your validator ID Next, try to get your `ValidatorID` from the SFC using your previously generated validator wallet address: ``` # Get your validator id sfcc.getValidatorID("VALIDATOR_WALLET_ADDRESS") ``` * Use quotes for "VALIDATOR\_WALLET\_ADDRESS". This should return **0**, as you are not registered as a validator yet:
### Unlock validator wallet Next, unlock your validator wallet to be able to execute the registration transaction (make sure to use the password you set before). Note that, you can perform this step (unlockAccount + createValidator) in a separate machine (different from the machine you'll run your validator node), or it'd be even more secure if you use hardware wallet to do it. ``` # Unlock validator wallet personal.unlockAccount("VALIDATOR_WALLET_ADDRESS", "PASSWORD", 300) ``` * Use quotes for "VALIDATOR\_WALLET\_ADRESS" and "PASSWORD". This will return “**true**” if unlocking the wallet was successful:
### Register your validator Next, send the `createValidator` transaction to register your validator **(the value is the representation of the smallest VC unit, so it must be divided by 1e18.** Alternatively, you can use `web3.toWei("200000.0", "vc")).` ``` # Register your validator tx = sfcc.createValidator("0xYOUR_PUBKEY", {from:"0xYOUR_ADDRESS", value: web3.toWei("200000.0", "vc")}) // 200000.0 VC ``` * Use quotes for "0xYOUR\_PUBKEY" and "0xYOUR\_ADDRESS". * 0XYOUR\_ADDRESS refers to the wallet created on the validator. * `0xYOUR_PUBKEY` MUST be the **canonical 66-byte lachesis-base format** — paste the `Public key:` value from the `opera validator new` output verbatim. The string starts with `0xc004…` and is 134 characters long including the `0x` prefix. Do not strip the `0xc0` type-byte or hand-construct the value: the canonical format is `0xc0` (Secp256k1 type byte) + `0x04` (uncompressed-key marker) + 32-byte X coordinate + 32-byte Y coordinate. As of `v2.0.14-elemont` the SFC contract rejects any other shape with `"invalid pubkey length"` or `"invalid pubkey type"`. A validator admitted with a malformed pubkey before this enforcement landed cannot produce verifiable consensus events and any stake delegated to it earns zero rewards.
### Check your registration transaction Make sure to check your registration transaction (could take a few moments to be confirmed): ``` # Check your registration transaction vc.getTransactionReceipt(tx) ``` Look for the **status: “0x1”** at the bottom, which means the transaction was successful:
You can also copy the `transactionHash` and go the VinuChain [BlockScanner](https://vinuscan.com) and check your transaction there: > ] This would look something like the below:
### Check your validator ID Finally, execute the following command again to check your `validatorID`: ``` # Get your validator id sfcc.getValidatorID("VALIDATOR_WALLET_ADDRESS") ``` It should now return something other than “**0**”:
Congratulations, you are now a VinuChain validator! Close the Opera console window by typing “exit”. ## Run your VinuChain validator node ### Restart your node in validator mode Before you run off celebrating, you need to **restart your node in validator mode**! Make sure your node is already synced to the latest block in read mode, and it's synced in --syncmode full. * Stop the opera process (read mode): ``` pkill opera ``` or ``` (validator)$ sudo killall opera ``` * Create an **empty file** and paste **validator node password** into it. Then head back to the console window where you started your node with the following command: **Mainnet:** ``` nohup ./opera --bootnodes enode://0281626c7d7fc8696300688cbb19f3781aabd981d74cd16f3f5cd7885a32da4d1d9d64afbb2416b93654935a3088afbe1a4a05d823ff2146e5d1d0c2cbdeca46@188.165.195.122:3000 --validator.id ID --validator.pubkey VALIDATOR_PUBKEY --validator.password PATH_TO_PASSWORDFILE > validator.log & ``` **Testnet:** ``` nohup ./opera --bootnodes enode://e2a95c1b8d85b018b8e88133bec342801b42e19b59a52e030462d04a5549f02fc57215b4ca97771ec6b3a0d30a78603fdccd2b5091c44f6ac439d6c8be8bc539@44.239.129.39:3000 --validator.id ID --validator.pubkey VALIDATOR_PUBKEY --validator.password PATH_TO_PASSWORDFILE > validator.log & ``` * You must replace `ID` & `VALIDATOR_PUBKEY` & `PATH_TO_PASSWORDFILE` variables with your own values. ## Update validator info ### Name & Logo If you'd like to set up a Name and logo for your node, please go to [Update Validator Info](/vinuchain/technical-docs/nodes-and-validators/update-validator-info.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
