Basically, it is an iOS chat application that functions without a backend. No central infrastructure, no corporate servers, nothing.</p> <p>The onboarding flow requires absolutely no phone numbers, emails, or personal identifiers. There is no account registry database to hack, which completely eliminates the usual honeypots for data leaks.</p> <p>Instead of routing data through a standard server farm, this thing uses the Solana blockchain as a raw transport layer. Every encrypted payload is wrapped into a transaction and pushed directly to one-time destination addresses. The cryptography stack is actually solid: they combined X3DH handshakes with Double Ratchet for rolling keys and forced fixed-size padding so observers cannot guess the length of your text.</p> <p>The social graph stays fully hidden because the app constantly rotates delivery points and adds decoy traffic to mess with timing analysis. It is a pretty cool practical application of web3 state machines instead of the usual token speculation. Check the repo if you are into decentralized networking._</p> showdev web3 privacy
