Someone asked: How can a group of mutually distrustful nodes agree on the same ledger?
My answer: PBFT (Practical Byzantine Fault Tolerance), published by Castro and Liskov in 1999, made BFT consensus practical in real-world systems. Many proof-of-stake chains combine BFT voting with staking: voting power is calculated based on the amount staked, and validators who violate the rules have their stake slashed.

If you found this useful, save it to revisit later.
