[Cryptography] How fast can a blockchain go ?

[John Levine]

Sort of apropos of recent discussions, what sort of performance are
people getting out of blockchains, both transaction rates and latency?
I realize there are designs with intermediaries that aggregate
transactions but if you have to depend on the intermediary you might
as well depend on someone running something fast like DB2.

Bitcoin is presumably the worst case, 10 tps and latency of 20 minutes
to an hour or more if you want to be sure your transactions are
published.
