In roughly 2,005 days, Bitcoin will obtain the holy grail of the 4 nines—that’s, 99.99% uptime for its international blockchain community. Based on in-house calculations, we estimate Friday November 14, 2025 because the date when Bitcoin will attain the milestone, assuming nothing goes flawed within the meantime.
Bitcoin is estimated to have been useful for 99.985% of its existence so far. In actual fact, that quantity can be as excessive as 100% if we measured solely from 2013 onwards.
However Bitcoin has gone down twice. In 2010 a “value overflow incident” noticed two Bitcoin addresses erroneously granted 92.2 billion cash every. On this occasion, the blockchain was down for eight hours and twenty seven minutes earlier than a softfork (minor replace) successfully cancelled the bugged transactions.
In 2013, Bitcoin briefly went down after a block was rejected by sure miners working completely different variations of the Bitcoin shopper. This resulted in a brief chain cut up which was resolved after six hours and twenty minutes when miners reorganized themselves onto the identical shopper.
Bitcoin vs. the US greenback
Dan Held, director of enterprise improvement at crypto exchange Kraken, posted a video to the primary cryptocurrency subreddit which claimed Bitcoin already had maintained a better uptime than Amazon, Google and Fb.
Nevertheless, not everybody thinks evaluating Bitcoin’s uptime to the world’s largest tech firms is a stable metric. As one commenter on Held’s put up advised, maybe Bitcoin’s uptime must be in contrast with that of different currencies:
“Why compare a currency to tech companies? How much uptime did paying with usd have? 100%,” they claimed.
Though some dispute this—claiming the US greenback has certainly, had downtime. A Reddit put up in 2017 identified that hyperinflation and different financial insurance policies stopped the primary model of the greenback in its tracks. 4 years later, it returned because the greenback we all know at present. These 4 years put it at 98.36% uptime, arguably lower than Bitcoin. However by this level, the dialogue is simply too meta to actually make any sense.
