Abstract #

The current reference deployment is implemented and operated exclusively on GenesisL1, an EVM-capable Layer-1 blockchain chosen to run this class of on-chain encrypted-metadata systems without depending on L2-specific trust or off-chain custodians.

Decentralized Science (DeSci) and broader intellectual property (IP) markets are increasingly constrained by a structural tension: open infrastructures excel at coordination, timestamping, and settlement, yet most valuable scientific artifacts—negative results, private datasets, trade secrets, pre-publication manuscripts, and commercialization pathways—require controlled disclosure. This paper introduces CIPNFT (Cryptographic Information Protocol Non-Fungible Token), a protocol and reference dApp for fully on-chain encrypted metadata NFTs enabling confidential data custody, verifiable integrity, and buyer-safe transfer with escrowed payments. CIPNFT stores ciphertext on-chain and maintains a compact, updatable key envelope that is re-wrapped to the new owner upon transfer, so only the current owner (or an optional view-key holder) can decrypt. Unlike conventional NFT designs that outsource metadata to mutable web servers or rely on opaque custodians, CIPNFT makes the ciphertext a first-class, consensus-protected object. In this sense, CIPNFT functions as an IP tokenization protocol: it tokenizes a cryptographic capability (the right to decrypt a specific encrypted knowledge capsule) rather than attempting to tokenize information itself.

The protocol supports two envelope modes: (i) a standard public-key “sealed box” envelope (based on X25519 and a proven AEAD construction), and (ii) an optional post-quantum envelope based on ML-KEM-768 combined with XChaCha20-Poly1305 to protect confidentiality against adversaries with large-scale quantum computers. Crucially, CIPNFT includes a two-phase sale mechanism (deliver then finalize) that forces the buyer to verify decryption correctness before releasing escrowed payment, addressing a fundamental fairness failure of encrypted-asset transfers on blockchains. We provide a precise specification of the on-chain data model, the client cryptographic pipeline, and the deal-flow state machine, including a complete Alice-and-Bob example for IP sale finalization. We analyze security, limitations (notably the impossibility of cryptographic revocation after disclosure), and offer a forward-looking discussion on ledger survivability: how CIPNFT can outlive any particular blockchain by preserving a self-describing cryptographic “data capsule” that can be migrated or re-instantiated without forfeiting confidentiality guarantees.

The construction #

Part	What the whitepaper specifies
Content	encrypted with XChaCha20-Poly1305 (a 24-byte nonce, a 16-byte tag) under a random 32-byte data key, at most 64 KiB; the chain stores the ciphertext, never the plaintext
Owner envelope, classic	the data key sealed to the owner's X25519 key with libsodium's `crypto_box_seal`: 80 bytes
Owner envelope, post-quantum	an ML-KEM-768 encapsulation with the data key wrapped by XChaCha20-Poly1305 under the shared secret: 1,088 + 24 + 32 + 16 = 1,160 bytes
View key (optional)	the data key wrapped under a key derived from the view key with BLAKE2b-256 (libsodium's `crypto_generichash`): 72 bytes, so that anyone given the view key can read the token without owning it
Commitment	`keccak256(data key)`, checked by a client before it decrypts the content
Sale	an offer deposits the asking price in escrow; the seller delivers the data key re-wrapped to the buyer, and no funds are released; the buyer checks the commitment and that the content decrypts; finalizing updates the owner envelope, transfers the token and pays the seller from escrow

All cryptography runs in the browser: the plaintext never appears on chain and never has to reach a server. A disclosure cannot be taken back: once someone has read a token, confidentiality is a legal and governance question, not a cryptographic one. A token's capsule is portable bytes that do not depend on GenesisL1's consensus rules, so it can outlive one ledger, by migration or re-instantiation.

In GL1X #

GL1X lists the CIPNFT tokens of GenesisL1 and opens a token's content in the browser with its view key, checking the data key against the on-chain commitment before it decrypts. See CIPNFT: encrypted NFTs.
