Avalanche protocol achieves transaction finality in approximately 2 seconds (or 300 milliseconds in practice on current networks), compared to 60 minutes for Bitcoin and 555 seconds for Ethereum, while tolerating Byzantine attackers controlling up to 60% of the network

“the bitcoin latency is one hour okay you have to wait for six confirmations for a pretty small attacker actually it turns out if the attacker is bigger you have to wait more than an hour for ethereum corresponding security it has more frequent blocks probably probability probabilities are on its side it's about 555 seconds that's math that was done by a phd student in in london um and uh there are other protocols that do sortition so you know a good protocol in the classical uh setting is algorand and it takes 50 seconds for this decision now avalanche takes it says two here uh we conservatively say two in the current network it's about 300 milliseconds”
