Seems to me it wouldn’t be that hard to test out these fast-blockchain claims. Set up a few hundred public-cloud hosts around the world and send a few thousand TPS at them, see what happens. They’re all open-source AFAIK. But it would cost some real money.
For the record, I’ve been pointed at 3 blockchain implementations which claim high scalability: * Nano en.wikipedia.org/wiki/Nano_(… * Avalanche semanticscholar.org/paper/Sn… * Solana solana.com Note that all involve a cryptocurrency. I have not verified any of these claims.

That would prove that they can handle the scale, but not that they preserve their guarantees (provided they even know what they are). You’d have to run something like @aphyr’s jepsen.io at scale.
