WebbNote that while this sounds like probabilistic finality in proof of work, it is not. Once ⅔ of validators have voted on some PoH hash, that PoH hash is canonicalized, and cannot be rolled back. This is distinct from proof of work, in which there is no notion of canonicalization.

WebbCase 2: SUT with Probabilistic Finality and Known Topology. Systems using lottery-based consensus have probabilistic finality. In controlled performance testing, the topology will be known. This will likely be the case in most permissioned deployments. In this case, a transaction is confirmed only when multiple nodes reach the same state. Webb18 dec. 2024 · It can be used on its own because it provides probabilistic finality, or it can be coupled with a finality gadget like GRANDPA. BABE is a slot-based algorithm. It breaks time into epochs, with each epoch being broken into slots. In Polkadot, each slot is six seconds long, our target block time.

Webb30 nov. 2024 · Most blockchain systems offer probabilistic transaction finality — transactions are not immediately final but become so eventually after a certain number of additional blocks have been appended to the chain.
