How validators work on SparqNet
A validator is a community member who has set up a node and locked at least 200,000 $SPARQ through the addValidator transaction, using the validator's address as an argument. They create blocks, the "randomness" seed used to select the next block creator, and are responsible for gathering and signing data on bridging and on blocks. Our validators require a token lockup of only 200,000 $SPARQ tokens to run a validator for gateway network, and 1,000 $SPARQ to mint an NFT that holds the binary for the app-chain with $100 fee for hard forks.
