i didn't say HD key i said BIP-39 word-mnemonic-key
reminds me, i should actually revise my key miner to print out the 24 word BIP39 with the keys
i was gonna play games this evening but games bore me far more than writing code
Discussion
this all made me realise there isn't a deterministic encoding scheme
24 words from 2048 word dictionary is actually 264 bits which is a full key plus a byte of check
i'm going to draft a scheme based on the bip39, this is an easy implementation and try to get some traction on it
no cold backup for nostr keys is wrawwwngg
