Support this work
Every instrument, essay and formula here is free, with no ads and no tracking. If this one was worth something to you, a donation keeps it that way: the servers, the AI, and the time.
Paid on Stripe’s secure page: cards, Apple Pay, Google Pay. Nothing is stored here.
Thank you. It arrived, and it will go into the next instrument. Stripe has emailed you a receipt.
Where it goes
- The servers: the small one that answers Lanterna’s AI and makes these payment pages, the chat, the storage.
- The AI that builds Lanterna’s networks and writes its shaders, for visitors without a key of their own.
- GPU time for the research written up here, such as the Ledger study, run on rented graphics cards.
- Time, which is most of it.
How it works
The amount is chosen here; the payment happens on Stripe’s own page, by card, Apple Pay or Google Pay. No card number passes through this site, and nothing about you is kept here. Stripe emails a receipt. The monthly donation is three euros for twenty months, sixty in all, and then it stops by itself; the receipt has a link to stop it sooner.
