Want to take it to the next level in crypto?
What if you launched your own validator to actively participate in a blockchain like Ethereum or Solana?
Here's a simplified guide to understanding what it involves 👇
🧾 What is a validator?
A validator is a network node responsible for validating transactions and securing the blockchain.
Since Ethereum 2.0 and the transition to Proof of Stake (PoS), anyone can become a validator... provided they meet certain criteria.
🎯 Why become a validator?
✅ You actively participate in network security
✅ You can receive regular rewards
✅ You support a decentralized ecosystem
But this role also implies technical responsibilities and risks that must be understood.
🧱 Steps to becoming a validator
1. Have the necessary funds
For example, on Ethereum, you need to deposit 32 ETH into a staking contract to activate your validator.
📝 These funds are locked. You cannot use them freely while staking is active.
2. Prepare your infrastructure
You must run a computer (server) that will remain connected 24/7.
Two options:
A server at your home (PC with Linux or a powerful Raspberry Pi)
A VPS (cloud server) rented from a provider (e.g., DigitalOcean, AWS...)
You must install:
A consensus client (e.g. Lighthouse, Prysm...)
A execution client (e.g. Geth, Nethermind...)
These two software programs allow you to communicate with the blockchain and participate in validation.
3. Generate your validator keys
Using an official tool (like Ethereum Launchpad), you generate:
Your public key validator
A withdrawal key
A protection password
You also receive a deposit.json file to use to deposit the 32 ETH.
4. Deposit the 32 ETH
You sign the deposit transaction from your wallet (like Metamask or Ledger).
Once the deposit is confirmed, you will be placed in a queue before being activated.
5. Launch your node
You start your server, launch the clients, load your keys, and your node synchronizes with the blockchain.
As soon as it's ready, you start validating blocks and receiving rewards... as long as your server remains active.
⚠️ Risks to be aware of
❌ If your node is misconfigured or often offline, you may lose part of your ETH (slashing)
❌ Staking is irreversible in the short term (ETH locked)
❌ You must protect your private keys and secure your server
🧠 In summary
Becoming a validator is possible for any blockchain enthusiast.
But it requires technical skills, resources and a little discipline.
If you don't yet have the skills or funds, you can start with pool staking to get used to the concept.
But if you want to be 100% involved in the ecosystem, setting up your own validator is a real step towards decentralization.
