PoH

WHAT IS POH OR PROOF OF HISTORY?

In blockchain, PoH (Proof of History) is a protocol that creates a cryptographic record of the time and sequence of events on a blockchain. It serves as the consensus mechanism in Solana, relying on a function called VDF to let all validators operate asynchronously.

Unlike PoS (Proof of Stake), PoH doesn’t define a system for selecting validators.
