That's Bitcoin. You can certainly wave your hands and imagine a
scheme where blocks are added faster if they are full of transactions or
something like that.
I see a fair amount of press for something called Zilliqa which
purports to create a high speed blockchain by sharding the chain
somehow. On the one hand, they've published a fair amount about it,
very little of which I have read. On the other hand, it's bristling
with snake oil red flags like an ICO where they say everyone has
gotten rich, and a warning banner across their web site saying to
beware of scams and imitations.
Anyone know them? I don't recognize any of the team on their web site
but they appear to be mostly in Singapore.

Considering that any program large enough to be interesting is large enough
to have bugs, I can hardly wait.
