One-block Irreversibility (OBI) is a proposed protocol change whereby a block will be considered irreversible as soon as a sufficiently large super majority of the currently scheduled block producers vote that the block in question should become the next valid block in the blockchain. The goal of this protocol change is to enable most Hive transactions to become irreversible within a few hundred milliseconds (before a second block has even been produced, hence the name “One-block Irreversibility”).
