Proof of capacity

Proof of Capacity is a consensus mechanism utilized in blockchain networks. It involves participants demonstrating their commitment to the network's security and validation process by dedicating storage space on their devices. This storage space is pre-filled with data, which is used to generate proofs of their capacity to mine or validate blocks. Proof of Capacity aims to be energy-efficient while ensuring network security and decentralization by allowing participants with available storage resources to participate in the consensus process."
