That would defeat the purpose. The goal is to make scraping costly, not profitable.
But, in this world, the website owner would receive tokens that they can then use to do whatever they want, including paying for servers and bandwidth. This is the sense in which the cycles aren’t wasted: the website owner now has cash to spend.
Effectively, both scrapers and ordinary users would be paying for the privilege of getting website bytes.
This also solves the problem of having to wait for your phone to solve the challenge while you’re browsing: you can buy or mine some tokens ahead of time and pay them as soon as challenged. So can the scrapers, but because they’re accessing enormous numbers of pages it’s hopefully prohibitively expensive for them.
> This makes Anubis challenges use a memory-hard proof of work function (argon2id) instead of just a CPU hard one. It also means that the "hey Claude vibeslop me a CUDA Anubis solver" route is on its way to being fundamentally dead.
Nice.
Meanwhile BOINC is well-established as the platform for distributed computation. If you can figure out how to squeeze its work units into Wasm challenges, I'm sure a lot of researchers would thank you.
