The Context Passport (ERC-721): A Deed of Digital Identity

The Context Passport is the lynchpin of a user's or agent's sovereign identity on SuperNet. Implemented as a standard non-fungible token (ERC-721), it functions as a unique, unforgeable "deed of ownership" to an individual's entire contextual self. However, its function goes far beyond a simple token.

The passport's primary role is to serve as a cryptographic anchor. Rather than storing bulky data on-chain, the NFT's metadata points to an encrypted Merkle root. This root is the tip of a vast, off-chain data structure (a Merkle tree) that contains all of the user's context, which is stored as sharded Vector Blobs. This design is critical: it allows for an identity to be immutably secured and globally accessible on the L1, while the underlying context data remains private, encrypted, and stored efficiently off-chain. Ownership of the passport confers ultimate, cryptographic control over this entire data structure—the ability to update it, prove ownership of it, and, most importantly, issue permissions against it.
