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.
