WebFinality A transaction has "finality" in distributed networks when it's part of a block that can't change without a significant amount of ETH getting burned. On proof-of-stake Ethereum, this is managed using "checkpoint" blocks. The first block in each epoch is a checkpoint. Validators vote for pairs of checkpoints that it considers to be valid. WebSo, arguments for security in cryptocurrency consensus analyses often rely on the cost to maliciously control a key resource: hashpower for proof-of-work and staked tokens for proof-of-stake.
