How Does the ‘Supermajority’ Concept Work in PoS Finality?
In PoS, deterministic finality is achieved when a supermajority, typically two-thirds of the total staked value, votes to attest to a block. Once this threshold is reached, the block is finalized and cannot be reversed without slashing the stake of the two-thirds of validators who attested to it, making reversal economically prohibitive.
