WebbFinality Proof of Stake blockchains can offer finality. After a small period of time, a block is declared final, which means that it can never be changed. All the transactions in that block and all previous transactions are permanent, immutable, and guaranteed forever. Proof of Work chains offer much weaker guarantees around finality.

While probabilistic finality is fine, waiting for a block to reach a certain depth in the longest chain is an inefficient mechanism, as it is designed to accommodate an anticipated worst-case where the network is under a certain level of network strain and attack. pastor cory bergman

"Webb11 dec. 2024 · Another powerful aspect is that it provides instant finality. In contrast to probabilistic finality observed in blockchains such as Ethereum, once a transaction is included in a block on a Cosmos chain and added to the chain, it is considered finalized and cannot be changed.

Webba complete probabilistic model of the Bitcoin Blockchain, setting the basis for follow-up AI applications on Bitcoin transactions. We ﬁrst formulate a set of conditional depen-dencies induced by the Bitcoin protocol at the block level and derive a corresponding fully observed graphical model of a Bitcoin block.

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.

Webb12 apr. 2024 · Finality is the condition that for a block to be considered a permanent part of the canonical chain it must have been voted for by at least 66% of the total staked ETH on the network. Researchers developed Casper specifically for Ethereum, and Ethereum is the first and only blockchain to have implemented it.

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.

WebbConversely, Nakamoto consensus protocols rely on probabilistic finality. In this case, the probability that a transaction won’t be reverted increases with time. The more blocks that are created on top of a block, thereby confirming it as correct, the more difficult and costlier it would be to revert a transaction in that block.
