> The verification problem is real. A 5-minute training run produces an objective val_bpb score that anyone can reproduce from the published source code. And this is actually valuable work, unlike most proof of work chain workloads.

Yes, thank you for the validation! That was the core of what sparked this for me -- my cartoon drawing of blockchain is that it's dependent on problems that are difficult to solve (improve this codebase), but easy to verify (loss went down).

Like you noted, this is also cool in that it's valuable work (unlike most of these workloads)

I appreciate the opportunities for optimization you've laid out (such as zkVM) but it feels like that would be optional compared to the basic thing here?

And yeah -- what one _does_ with the crypto-credits is pretty open-ended. Like you said, drawing on the swarm for training or inference or whatever you need -- it feels like the sort of thing that one could use as a GPU battery of sorts. Most of my personal GPU work goes in bursts -- but most of the time my GPU is sitting idle.

Most of the other GPU share-cropping sorts of ideas I've seen floating around lack the ability to independently prove that work was done. Having a global metric for a shared target like this seems to solve what has been lacking in a lot of other distributed systems I've seen.

Looking at the graph on the website, it looks like it's already got a bit of a scoreboard and independent verification / validation of results. Feels like it would be a relatively small jump to crowdsource this and put it into a formal blockchain.

But the next natural question is: Would we stand to gain anything by adding blockchain to this?
