Proof-of-Work (PoW) is a consensus algorithm that uses specialized data servers (miners) to confirm transactions on a distributed and decentralized public ledger called “blockchain” and continually produces new confirmed transaction files or blocks to add to the chain. With PoW, miners compete against each other to verify transactions on the respective network for rewards.
Proof-of-Action (PoA) recognizes contribution and energy usage tied to a given blockchain, which generates a IZE reward for the successful confirmation on the supported blockchain.
