Polkadex Testnet: How to run a validator node
Start running your own validator node on the Polkadex Testnet!
As Polkadex approaches Mainnet launch, it becomes increasingly important to have a secure, distributed network validated by nodes around the world. While Mainnet is still a few weeks away, the Polkadex Testnet is now live. From today anybody can run a validator node and start securing the Polkadex Testnet. You can even claim Test Tokens to start staking as a validator. This is a huge step on the road towards the Polkadex Mainnet launch and one that many of the tech-savvy community members will be excited about. Read on for details about what being a Polkadex validator means and for a helpful guide on how you can start validating the Polkadex network now.
Who are validators?
In Proof of Stake (PoS) blockchains, validators are in charge of verifying transactions as they are broadcast to the network. They maintain system efficiency, participate in voting and form new blocks in the blockchain.
Validators run costly operations, ensure high communication responsiveness, and build a long-term reputation of reliability. In fact, they stake their PDEX as a show of good behaviour. If validators deviate from their protocol, their staked PDEX gets slashed. However, if they play by the rules, they get paid in PDEX. While any willing node can become a validator, only a limited number (expected to be hundreds in Polkadex’s case) is selected when the validator set is refreshed (a couple of times a day).
What about staking?
Polkadex will run on a nominated Proof of Stake (nPOS) consensus, which will allow anybody in the network — not just validators — to stake their PDEX and secure the network. Stakers will be able to ‘nominate’ validators.
Therefore, even if you are not a validator, you will still be able to stake and earn on your staked PDEX.
Who can be a validator?
Anybody! Polkadex is a decentralized public chain, which means anybody who chooses to can become a validator of the chain. However, running a validator node might require more advanced technical knowledge and hardware. In fact, hardware requirements will probably increase as Polkadex matures. Therefore, while validating is open to anyone, some community members may find it easier than others to do so.

Claim Test Tokens
In order to become a validator on the Polkadex Testnet, you will need some Test Tokens. The Polkadex team has designed a Twitter bot that will serve as a Test Token ‘faucet’ for this phase of the Testnet. To claim Test Tokens, copy and paste the text below into a tweet, paste your account/wallet address where it says [ACCOUNT], and post it. Soon after, you’ll receive Test Tokens to start playing around with.
👋 Hey @polkadex it's [ACCOUNT] here, please give me some #PolkadexTestTokens! 📲
Testnet means Testnet
As the name may suggest, the Testnet involves testing. In other words, the Testnet is not production-ready, and is still a work-in-progress simulation environment that is ‘meant to break.’ As such, the Polkadex team may shut down or wipe the chain without notice. A reset of the Testnet chain means that your Test Token balance will go back to zero and you will need to claim Test Tokens again by following the Twitter faucet bot instructions detailed above. However, you will also have to create a new account/wallet address, as the faucet bot is only set up to fund each address once.
