Trustlines validators ensure the security of the Trustlines Blockchain by validating transactions and adding blocks to the Trustlines Blockchain. They are anonymous. To gain a validator slot, validator candidates take part in the validator auction and stake ETH on Ethereum. Their ETH deposit can get slashed for equivocation. Validators earn TLC through transaction fees and block rewards. They can additionally take part in the green field governance experiment of the Trustlines Blockchain.
