Proof of History (PoH) is a unique way to keep track of time and the order of events on a blockchain. Imagine a clock that continuously records timestamps in a way that’s impossible to tamper with. That’s essentially what PoH does. It creates a verifiable record of when transactions occur, making it much faster and easier for the network to agree on the order of events. This allows blockchains like Solana to process transactions incredibly quickly, as they don’t need to wait for confirmations from multiple parties to establish the correct order.
