SOL - Solana

Proof of History (PoH)

  • incorporating time into the blockchain to reduce the load while processing blocks

  • Verifiable Delay Functions

    • need sequential computation to evaluate

    • events and transactions are hashed with the SHA256 hash function

    • takes the output of a transaction and uses it as input for the next hash

    • no parallel processing allowed, able to determine exact time required to complete the steps e.g. SHA256(”random string”) output: hash1 SHA256 (hash1) output: hash2 SHA256 (hash2) output: hash3

    • Advantages

      • having timestamp snapshot provides a clear verifiable sequence of transactions

      • speed up validation process by minimizing node communications on timestamp

  • also involve Proof of Stake (PoS) mechanism

    • only people who staked can be validator to vote on validity of PoH hash, bad actor will be penalized
