I personally love the idea of using a blockchain to send anonymous, encrypted messages.
I tried out BitMessage I think it was, a while back; I think a stripped-down lightweight version of it would be very useful.
Maybe with a Web browser doing encryption, decryption in-browser (already Tutanota etc. do this). Not sure as to the the other pieces that would need to be deployed.
- wslh 11y agoBitMessage is not secure (query BitMessage security on Google) If you are interested, you can use OpenPGP with ECC ( and the JS implementation https://github.com/Jaxx-io/openpgpjs-secp256k1 https://github.com/Jaxx-io/openpgpjs-secp256k1 ) Take into account that you need to use different keys for signing and encryption and the BIP 44 can be useful for this purpose.
- CyberDildonics 11y agoI don't think BitMessage is a blockchain is it? It doesn't create or use a shared ledger or consensus for that ledger, it just sends all messages to everyone so that the sender and receiver are much more difficult to track down.
- NobleSir 11y agoUsing a blockchain for messaging means all your messages are stored until quantum encryption can come along to crack them open. Sure the usual distributed setup which blockchains like bitcoin have has advantages (namely in the hiding of metadata), but I'm not sure an actual blockchain is necessary or optimal for this.
