One of the most common criticisms leveled against Bitcoin is that it is slow, at least compared to newer imitations. But its level of decentralization means just 6 transaction confirmations provide complete protection against double spending.
So how many confirmations are required by the altcoins to provide the same amount of work to secure the network? And how long do those confirmations take? Luckily, developer Luke Childs made a thing, then Charlie Shrem kindly tweeted that thing.
