VSC Core

Verifiable Structural Compression

Store a full state once. Store only ordered, verifiable deltas after that. Reconstruct the latest state and verify it by root hash.

Proof Flow

WordPress-style folder: one base, two ordered deltas, one verified latest state.

Base snapshot 21A8390BFA3F · 1.58 MB

↓ Delta 1: database.sql 376 B stored

↓ Delta 2: vsc-demo-plugin.php 265 B stored

Latest verified state 954BEB0FF3AA · PASS

Visual Token Grammar

Each VSC token is represented as a human-readable SVG seal. The seal encodes token type, state relationship, and verification identity.

Verification

All cryptographic verification runs against SHA-256 root hashes stored in the token JSON. No external service required.

PASS Chain restore — latest state reconstructed from base + 2 deltas
PASS Chain verify — reconstructed root hash matches expected latest root hash
PASS verify-all — FAIL: 0 across all registered tokens
SHA-256 Latest state verified by root hash

Reproduce the Demo

From a clean clone of the repository:

npm install
npm run vsc -- demo:run

Or run individual steps:

npm run vsc -- demo        # create test fixture
npm run vsc -- backup test-wp   # base snapshot
npm run vsc -- delta <base> test-wp   # delta
npm run vsc -- chain <base> <d1> <d2>
npm run vsc -- restore <chain>
npm run vsc -- verify <chain> <restored-folder>
npm run vsc -- verify-all
