WebJun 15, 2024 · Polkadot has a hybrid consensus protocol that splits the finality gadget (GRANDPA) from the block production mechanism (BABE). This is a way of achieving probabilistic finality (after a certain time the block will be finalized with a probability close to one) and provable, deterministic finality (implying a finalized block stays final forever.) WebAug 3, 2024 · This finality is an important requirement, as each chain must be certain that a transaction they have verified on the opposite chain will not be reverted.
