+# note⛏️
+**notemine** mines nostr notes, is written in rust, targets web and compiles to wasm. Variable difficulty and realtime hashrate. There's a [demo](https://sandwichfarm.github.io/notemine).
+
+If you're looking for a native miner that leverages hardware acceleration, check out [`notemine-hw`](https://github.com/plebemineira/notemine_hw)
+
+# bindings

+//You shouldn't need to pass id or sig, and created_at is optional.
