Proof of Space Time (PoST) is a consensus mechanism that combines storage capacity and time as the basis for block validation in a blockchain network. PoST requires participants to allocate and prove the availability of a certain amount of storage space over a period of time. It offers an energy-efficient alternative to Proof of Work (PoW) and provides security based on participants' commitment of storage resources rather than computational power. PoST allows for the fair distribution of block rewards while still ensuring network security and consensus.
