1. Abstract

NID is an on-chain protocol that converts human-created pixel matrices into deterministic, cryptographically referenceable identity objects. Each NID artifact is both a reproducible visual object and an information-bearing structure that can be integrated into identity and key-derivation workflows.

2. Motivation

Conventional NFT workflows are dominated by automated generation pipelines and external media links. NID focuses on deliberate human input and deterministic reconstruction from structured pixel data. The intent is to preserve authorship traceability and reduce low-effort, automated artifact flooding.

3. Protocol model

Stage	Input	Output
Grid definition	Fixed matrix size (8x8 to 128x128)	Bounded pixel-coordinate space
Serialization	Pixel positions and values	Deterministic byte or hex representation
Entropy measurement	Non-empty pixel distribution	Quantified information score
Fingerprinting	Serialized matrix data	Cryptographic hash identifier
Reconstruction	On-chain encoded matrix	Exact visual artifact recovery

4. Security positioning

NID artifacts are not private keys and are not a standalone wallet credential.
NID data can be combined with a passphrase and salt in a KDF workflow.
Recommended KDF examples include Argon2, HKDF, and PBKDF2.
Security outcomes depend on full pipeline design, not only on the visual artifact.

5. Difference from traditional NFT patterns

Primary object is deterministic matrix data, not only a referenced image URL.
Reproducibility is intrinsic to the encoded artifact representation.
Creation model emphasizes human intent and manual construction effort.
The artifact can be treated as an identity-linked entropy source in broader systems.

6. Use cases

Human-created digital identity artifacts.
Proof-of-intent creation pathways in anti-automation communities.
Additional entropy component in secure derivation pipelines.
On-chain visual identity state objects for protocol ecosystems.

7. Current implementation status

NID editor functions are active in the member area, including save and load workflows. Minting and full on-chain submission are planned for a later phase.
