DApps need to provide blockchain data for end users, but developers don't want to deal with the hassle of running their own nodes to do this. Our protocol incentivizes a decentralized network of remote procedure call (RPC) nodes to relay data from any of our supported blockchains to the DApp users who need it. DApps send their RPC requests to our global network of nodes, which relay the requested blockchain data back to those DApps. For providing this service, our node runners earn $POKT rewards.
