Dergigi has set up an example prism. You can send sats to @ODELL and @Marty Bent via⚡firstname.lastname@example.org.
Then there's the transparency issue pointed out in the article and by @Buck on nostr:
I’d love to see something like this built in a trustless way such that you don’t have to trust that the prism will split the payment (which is how it’s done in podcasting 2.0 right now). I built a PoC of this for a hackathon a few years ago using HODL invoices and LSATs, in a project ironically called “Prism”... https://github.com/bucko13/prism#split-payments
was gonna say this just sounds like the concept in podcasting 2.0 which i think is very good but then i scrolled further down and saw them mention that specifically. I'd like to see it implemented in other ways
