🕵️Become a validator

Intro

Creating a new validator helps the network to be more decentralized and resilient. On this page we will show you how to create a validator to prepare it for the staking process.

1. Prepare your keypair

Let's imagine that you have a pair of ed25519 keys that you will use to control your validator. To generate such a pair - use the tutorial here:

LogoDefault Ed25519 transactions | KLYNTAR Docs

Let's say a key pair looks like this:

const keypair = {

    pub:"3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R",

    prv:"MC4CAQAwBQYDK2VwBCIEIDteWfNev7NOlNmwP8Irwg5miWKoErYGV+UU5VrFgYev"

}

2. Create the transaction to call staking system smart contract

Use the Web1337 SDK to create a call to system smart contract

import Web1337 from 'web1337';


const web1337 = new Web1337({

    chainID:'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa',
    workflowVersion:0,
    nodeURL: 'http://localhost:7332' // set the URL to your own node

});


const keypair = {

    pub:"3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R",

    prv:"MC4CAQAwBQYDK2VwBCIEIDteWfNev7NOlNmwP8Irwg5miWKoErYGV+UU5VrFgYev"

};

const shardID = "shard_0";

const fee = 2;


let payload = {

    contractID:'system/staking',

    method:'createStakingPool',

    gasLimit:0,

    params:{
        
        percentage:30,
        
        poolURL:'http://localhost:7335', // set your own domain/ip
        
        wssPoolURL:'ws://localhost:9335' // set your own domain/ip

    },

    imports:[]

};

const nonce = await web1337.getAccount(shardID,keypair.pub).then(account=>account.nonce+1);

const txType = "WVM_CALL";

let tx = web1337.createEd25519Transaction(shardID,txType,keypair.pub,keypair.prv,nonce,fee,payload);

console.log(tx);

web1337.sendTransaction(tx).then(()=>{

     console.log('Sent status => ok')
     console.log(`TX ID is => `,web1337.blake3(tx.sig))

}).catch(err=>console.error('Error during pool creation: ',err))

Output example:

{
  v: 0,
  creator: '3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R',
  type: 'WVM_CALL',
  nonce: 1,
  fee: '2000000000000000000',
  payload: {
    contractID: 'system/staking',
    method: 'createStakingPool',
    gasLimit: 0,
    params: {
      percentage: 30,
      poolURL: 'http://localhost:7335',
      wssPoolURL: 'ws://localhost:9335'
    },
    imports: []
  },
  sigType: 'D',
  sig: 'T9uU7l58HEPgzcQMUObvZYxLKb28WRN2F21ec5Bt++wAJTZynUh1ofI0Pi98SMjLxOqQqmyLuFimJNaV7zCNDg=='
}


Sent status => ok
TX ID is =>  731c5f2ca6e1690b447da956c1a306692232e2101e8f89e8813be5bee3c5c37e

Check the transaction status

Go to explorer, choose the filter and paste the transaction ID to searchbar

Yes, as expected the pool creation process was successful

Please note that this transaction was in a block that was in epoch 89 (see the first part of the block identifier before the colon sign)

3. Wait untill the next epoches

So as soon as 3 epochs have passed, you can go and check whether your pool has appeared in the state

Great, as you can see the pool was indeed added to the state

At the moment this pool is empty - it has:

  1. No staked native coins(so see Default staking)

  2. Staking points called UNO(unobtanium)(so see Multichain multiasset staking)

Also, when creating a pool, the address of the pool owner is automatically added to the list of stakers, although the initial stake values ​​are zero

Now everything is ready to move on to the most interesting part - staking

4. How much do you need to launch a validator

Just visit the main page of explorer and check the section Network Parameters > Validator Stake Size

This amount of coins is required to make your validator eligible to be elected to a quorum and/or to generate blocks

Also, on the validator page you can see how many coins are already staked on it

As you can see here validator has 55 000 staked coins while required minimum is 50 000. So this validator is eligible to generate blocks and take part in approvement.

5. Start staking

Go to the next sections to learn more about staking and multistaking. How to do it via user interface or via SDK - details are in the next sections ☺️

Short FAQ

Does pool and validator are the same ?

Yes ✅

What is the minimum / maximum stake ?

There is no maximum stake, but there's a minumum. You can see this value on the main page of explorer in Network Parameters section

Is it possible to reduce the await time for creating a validator ?

Because of network architecture - no
