Solana solves this problem by using an innovative technology called Proof of History, which allows these “timestamps” to be built into the blockchain itself. This is done through a verifiable delay function, a VDF.
26 sie 2024 · Proof of history allows the distributed system to agree on time without requiring communication and consensus beforehand. This is achieved by each validator on the network maintaining its own clock by encoding the passage of time in an SHA-256 sequential-hashing verifiable delay function (VDF).
Proof-of-History (PoH) is a scalability solution that allows compact blockchains with a verifiable history to be created and secured. It works by creating a timestamp for each block and then using a Verifiable Delay Function (VDF) to prove that the timestamp was generated in a certain amount of time.
