Show dev: A serverless messenger that operates without personal data
_Ran into an open-source project called PrivaMesh yesterday and decided to look under the hood since their architecture choice is wild. Basically, it is an iOS chat application that functions without a backend. No central infrastructure, no corporate servers, nothing. The onboarding flow requires absolutely no phone numbers, emails, or personal identifiers. There is no account registry database…
Yesterday, I discovered an open-source project named PrivaMesh and decided to examine its inner workings due to its unique architecture. PrivaMesh is an iOS chat application that operates without a backend, central infrastructure, or corporate servers. It does not require phone numbers, emails, or personal identifiers during onboarding, eliminating potential vulnerabilities for data leaks.
Instead of routing data through a standard server farm, the application leverages the Solana blockchain as a raw transport layer. Encrypted payloads are wrapped into transactions and sent to one-time destination addresses. The cryptography stack is robust, combining X3DH handshakes with Double Ratchet for rolling keys and implementing fixed-size padding to prevent timing analysis.
The social graph remains hidden as the app constantly rotates delivery points and adds decoy traffic to disrupt timing analysis. This open-source project represents a practical application of web3 state machines, deviating from the norm of token speculation. For those interested in decentralized networking, the project's repository is available for exploration.
