I'm working on an open-source "decentralized" app that allows viewing and posting text messages.<p>Posts are stored in the blockchain and not censurable to some extent.
Fetching of the blockchain data is done through polling of public apis (blockfrost or koios).
Posting a message requires a Cardano transaction which implies fees but this would also prevent spam.<p>Private messages between users are encrypted with a public key generated from each user wallet signature.<p>The whole app is hosted on github pages and open source: <a href="https://github.com/alucao/decon">https://github.com/alucao/decon</a><p>Any feedback or thoughts are welcomed.
