What is ANProto?

ANProto is the spiritual successor to secure-scuttlebot, but without all of the extra stuff that is difficult to maintain.
ANProto is an attempt to argue that ATProto is too involved in it's own networking infrastructure to be usefully decentralized.
ANProto operates under the working theory that Nostr will never reach anyone besides Bitcoiners.

Bring your own network!

ANProto works over any networking stack. Open the messages from your URL bar! Email them to your friends! Load them on a USB stick an slingshot them over a river! ANProto is non-networked, so you can send and retrieve the messages anyway you want. Try the fetch API or Websockets if you want a good place to start. But maybe dork out trying to send ANProto messages via Bluetooth, LoRa, or sync them via local wifi like you did with Scuttlebot!

the JavaScript library!

use Deno or your browser

import { an } from './an.js'

console.log(await an.gen())
