@ -84,7 +84,7 @@ Blockchain consensus protocols like Bitcoin do not finalize/decide on one block
Traditional consensus protocol research has focused on producing protocols that are asynchronously safe (i.e.\ blocks won't be reverted due to arbitrary timing of future events) and live in asynchrony (or partial synchrony) (i.e.\ nodes eventually decide on new blocks). On the other hand, the Bitcoin blockchain is not safe in an asynchonous network but is safe and live (for unknown block-depth or ``confirmation count'') in a ``partially synchronous network.''
Traditional Byzantine fault tolerant consensus protocols have precisely stated Byzantine fault tolerance numbers (often can tolerate less than a third Byzantine faults, or up to $t$ faults when there are $3t + 1$ nodes)[CITE]. On the other hand, it is less clear exactly how many faults (measured as a proportion of hashrate) the Bitcoin blockchain protocol can tolerate.
