hello #nostr, here goes another #bitcoin bounty. Whatever I think is best answer gets 20.000 sats zap directly today.
Let me know why this is a bad idea:
Let's say I want to create a digital recovery of my wallet, in case physical backup is lost, found or destroyed.
Here is a setup I came up with:
0. Create a single sig BIP39 Mnemonic (24 words) with a Passphrase (strong, +12 characters & mixed )
1. Write on paper. Separate into two parts (e.g. 11 / 13 words)
2. Encrypt each of the two parts with AES-256 encryption, using your Passphrase as key to decrypt (like Samurai wallet did)
*Method: Write from paper into an encryption tool separately each of the two and do it offline on a open source encryption app, then erase it completely afterwards before you go online with that device.
3. Store each of the encrypted parts separately in four or more different email clients /clouds /chats, but never leave the two of them on a single client. I thought of clients that use strong encryption as a 2nd layer of protection, like tutanota, protonmail,, element, session, signal ... why 4 or more? well if you are not trusting that any of these centralized company servers will live forever then you better diversify the risk of being locked out of your files forever. You could also store them locally, but that just defeats the purpose of them being globally accessible, not relying on a physical location or material that can be damaged/destroyed/found by unwanted.
Thanks to all for your time.
Its fun to fantasize. My authism runs strong these days lol so I wanted to get a good counterpoint to my assumption. This is a problem I thought about alot
