fs-announce is simple protocol that enables private messages from NFT creator to owners. We believe that with this basic socialFi block we can build something truly useful. But you shall not be decieved by it's simplicity, as it can be used as Pateron&OnlyFans substitute even in it's current form.
We build it with the use of IPFS, Lit Protocol, Polygon and NFTport. Lit protocol gave us very convenient high level api for messages encryption. Those messages are then stored on IPFS, while their hash stored on-chain. We design this system in such a way that you only need to post hashes on Polygon even with NFTs from other chains, this means that there is very little complexity added with new chains, so system is pretty scalable.
