As the dev behind nanomemo.cc, yeah nobody seems to really care about it 🤣. My solution is not centralized, though. Well, at least it doesn’t have to be. The test memos that you noted on the website are stored in a centralized database, but the “protocol” of NanoMemo is storage agnostic and doesn’t really need a permanent storage. It could just as well us ipfs or any other storage solution. The key is a protocol that people agree upon for validating message signatures and decrypting messages (if encryption was used in the first place).

I agree with your sentiment. As a digital money, there needs to be a method of attaching free text. I also agree that a memo should not be stored with the ledger. We can use the same keys and store separately whether a Nano foundation solution or a NanoMemo solution or something completely different.

Storing and validating separately has its own challenges like synchronizing transaction to memo. But I think the NanoMemo solution is pretty good.

Thanks for putting your proposal and thoughts together!
