The Witnet protocol runs a single purpose blockchain with a token called WIT, which relies on a P2P network. The nodes on the network are called witnesses, and are incentivised by the WIT token to:
Retrieve, Attest and Deliver data from any open API
Mine a block to be added in the blockchain
Be a bridge-node and connect the Witnet protocol to other protocols, such as Ethereum
Witnet-Ethereum flow
Because the Witnet blockchain is free, open, and neutral, you can run your own node and mine blocks on the Witnet blockchain. Every node maintains the history of all the transactions on the blockchain.
