In IBFT 2.0 Proof-of-Authority (PoA) networks such as Palm, validators are nodes that validate transactions and blocks. Validators take turns to create the next block. Before inserting the block onto the chain, a super-majority (greater than 66%) of validators must first sign the block.
Validators earn rewards for keeping the network honest. Validator nodes will initially be run by key stakeholders and technical partners.
