@Peter R
can
you prove that no computer network in the world could be made to do 50,000 tx/s by next year?
Reversing the burden of proof won't get us ahead in a discussion.
If you do the math using ~224 bytes for a standard transaction, you end up with 6.7GB blocks for that rate if the 10-minute confirmation time is kept.
Let's set aside the matter of lack of demand for such rates for now, and the speculation that maybe enough network participants would accept decreasing the target time to 2.5 minutes or thereabouts so one wouldn't have to transfer the data in ginormous blocks.
None of the publicly released Bitcoin Cash clients are able to handle > 1GB in production as part of their current make-up. And you can bet there's some major engineering work to be done system-wide to handle high rates.
So what Craig must be talking about is a piece of the puzzle that has not been seen by the world.
Now, it's fine talking about it if it exists and is planned for rollout next year. But it's not a particularly helpful way to promote Bitcoin Cash at this time. It would be better if such claims were accompanied by plausible system designs, studies on prototypes, public demos of the tech etc.
Like others have said, if we can get from where Bitcoin is now to an organic volume of 500 tx/s next year that would already be a massive accomplishment and extremely good for Bitcoin Cash. If we can grow the network faster, even better.
Bear in mind that generating artificial traffic of 50000 tx /sec wouldn't be that hard. If someone wanted to do it just to prove a point, they could. It would be much harder and more costly to have proper infrastructure ready and deployed to handle that as a matter of course.
