Okay thanks, and when you speak about "crypto based messaging" what does it means?
Various schemes to use the cryptography of blockchains to send messages in a decentralized and theoretically secure way. The classic version of this used by early darknets was Bitmessage. There's some more recent takes via Ethereum too
Ok thx
If you see something that says it uses blockchain to store your data, run away from it. Blockchain is used to make records permanent, not private. The only way to delete data from a blockchain is to erase the blockchain from existence, which cryptocurrency bros will never want to do (because that's where all their money is).
I miss the good old days when crypto meant cryptography and not cryptocurrency.
Absolutely false, you can store data encrypted on the blockchain, such that it can be read only by a recipient. In this way it functions no differently than sending an encrypted email. But Bitmessage isn't even a cryptocurrency, it just uses the ideas from them
Why would you want to store messages, even encrypted ones, on a publicly accessible distributed database with no delete function?
Bitmessage was created well before the concept of post quantum encryption was widely discussed, so it is not safe for that use case.
... because it's publicly accessible with no delete function
Correct, and that is bad. Very bad. The fact that in BitMessage, "every message gets sent to everyone" is something nobody wants or asked for.
Seems self-evident to me why the protocol has been languishing and mostly ignored for the past decade or so.
Thx
