Description
Solo dev. built in my spare time.Raven uses a combination of steganography and cryptography to create a metadata resistant messenger. It encrypts any piece of text on your device and stores the ciphertext on Solana. It works pairwise with keys, users decrypt locally on their device- no accounts. I do run the relayer and a retention sweeper (not claiming peer to peer). One more thing, every write is signed by the same pool wallet, so anyone can see volume/timing. Check the white paper below and there’s been no audit.Several variations include: public, private, and stealth (for fun, i’ve hidden a public raven in this post)White Paper: https://oara.ai/raven-whitepaperThe crypto and encoding core is open source.

Could you build this?
Partial Basic client-side Web Crypto and Solana RPC writes are simple to vibe-code, but secure steganography and true metadata-resistant messaging require rigorous cryptographic implementation.
What it would actually take: The system combines client-side public-key cryptography (e.g., X25519/Ed25519), a robust natural language or binary steganography encoder/decoder, and Solana memo/custom program transactions. The difficult aspect is creating steganographic encodings that are indistinguishable from normal human text and preventing side-channel metadata leaks. Requires domain knowledge in information hiding, cryptanalysis, and blockchain data modeling.
