Nostr to self: #dvm in the nostr context stands for "Data Vending Machine", something like a micropayment coin-operated API that ingests micropayments and data as raw inputs and emits processed data as output. The relevant protocols are Lightning L402, PSBT (BIP 174), and NIP-90, though apparently it's so new (or controversial, I dunno) that it's not yet merged into https://github.com/nostr-protocol/nips (see pull req 495).

What #dvm (context: Bitcoin/Lightning/Nostr) isn't:

* Dalvik Virtual Machine (context: Android/not-Java)

* Doctor of Veterinary Medicine

* Dynamic Video Memory (context: GPU RAM)

* Dividend Valuation Model (context: finance)
