CeMail

An SMTP compat "mail" client that uses Ceramic documents to sync & relay mail-like messages between identities. Roughly related to did-comm.

some fundamentals

The fundamental idea of a self sovereign identity is the "DID", a decentralized identifier, looking like did:key:zkmanycharacters. DIDs are uniquely identified by key material of an user, derived by some random seed only the user knows. DIDs can be resolved / expanded to DID documents that contain information about the public keys a user uses for communication and authentication purposes.

At its core, the Ceramic protocol uses DIDs to represent identities that are interacting with documents, atm did:3 and did:key are supported: https://developers.ceramic.network/learn/overview/#authentication. On top of Ceramic, IDX is adding a layer of well formed documents that contain additional information about the user, e.g. an user "profile".

NFTropy

NFtropy is about building new art based on composable collections of seed NFTs.

The baseline of NFTropy are 8x8 bitmap "tiles" that can be interpreted as bitmap pictures if you want so, e.g.

the binary hex string b44861ea32a51020 yields these bits:
