#WebBotAuth
We also had @bobbiechen.com join us for part of community day from connecting on the skyline, and we learned a bit about webbotauth datatracker.ietf.org/wg/webbotaut...

Will Allen VP Product @cloudflare.social talked about:

- AI Crawl Control (and Pay-Per-Crawl)
- webbotauth at IETF (and a little on AIPREFs)
- x402 payment FDN with Coinbase

… and answered a LOT of questions about how Cloudflare is NOT gonna be the next gatekeeper 🙃

I finally had a chance to catch up on webbotauth 124
datatracker.ietf.org/doc/agenda-1...

A crazy, half-baked thought - how much of the publishing web could be distributed through Authenticated Transfer instead, and in doing so shift costs from the publisher to the consumer (readers and crawlers)?

Cloudflare does webbotauth too (it's driven by some of their devs, though I don't know if they'd support it with just the signature). Maybe the other CDNs will come up with different setups, to keep things interesting. Also, it's by no means a standard or stable yet.

Not all bots are evil. Some book flights, run SEO audits & help users quietly in the background. Web Bot Auth is the new standard that lets websites verify which AI agents are legit using cryptographic signatures.

Web Bot Auth (webbotauth)
https://datatracker.ietf.org/wg/webbotauth/about/

これについては初耳だったけど、preference signalなんかと比べてもいかにもまずそうだし、これに絞って別個に反対運動を展開するに値するのでは。というか下手したらWeb Environment Integrityの再来にならないかこれ

This feels like the webbotauth problem, except trying to use user auth as a signal. The accessing user is paying a cost (identifying their client and giving parties a veto) to solve a service auth problem (which, fairly, is hard).

Chairs have decided to revisit and publish requirements and use cases. A good decision!

WebBotAuth is a proposed standard for signing HTTP requests so the server knows who is requesting the data. All fine so far; it's what we use for ActivityPub for domain blocking, for example.

I'm in the #webbotauth meeting at #ietf124. #thanksihateit

There's Web Bot Auth datatracker.ietf.org/wg/webbotaut... which is meant to facilitate the latter, and Cloudflare also uses it for their "pay-per-crawl" setup (though I wish there were other companies implementing that too)
