# LPS-1: Deterministic Digital Provenance (xxxiii.io)

An open standard for proving the origin and integrity of digital content. Not DRM: it does not restrict access, it proves origin. Anyone may read, anyone may verify, no intermediary is required. Operated by UnyKorn LLC (Wyoming).

## What it does
SHA-256 canonical hashing at word, paragraph and chapter level. Four independent Merkle trees (manuscript, artifact, image, prompt) combined into a single edition root. That root is anchored to Polygon Mainnet (chain 137) with a block timestamp and cross-timestamped to Bitcoin via OpenTimestamps. Forward-only edition lifecycle. Non-upgradeable contracts.

## Live, checkable facts (read from the chain at the edge)
- LiteraryAnchor editions: 6; latest anchored 2026-02-17T11:21:17.000Z; work "The 2,500 Donkeys"
- PublishingKernelV2 editions: 3; canonical edition id 2
- AuthorIdentity: real name Kevan Burns; pseudonym Kidd James; 12 works registered
- Block 94119539; 11117341 blocks since genesis block 83002198
- Reference implementation tests: 58 passing (npx hardhat test, 2026-09-09); the project's own compliance document reports 293 across its full suite (self-reported, not re-run here).
- Security review: internal; no external audit as of 2026-09-09.

## Authorship
The DOI and ORCID carry the real name (Kevan Burns); the on-chain AuthorIdentity record and the published works carry the pseudonym (Kidd James). Same person; the contract states both.
