Interactive ZAP1 lifecycle event simulator.

What it does

Walk through all 9 ZAP1 event types in order:

  1. PROGRAM_ENTRY - wallet registration
  2. OWNERSHIP_ATTEST - operator attestation
  3. CONTRACT_ANCHOR - hosting contract committed by hash
  4. DEPLOYMENT - miner installed at facility
  5. HOSTING_PAYMENT - monthly hosting invoice paid
  6. SHIELD_RENEWAL - annual privacy shield renewed
  7. TRANSFER - ownership moved to new wallet
  8. EXIT - participant exit or hardware release
  9. MERKLE_ROOT - lifecycle tree root anchored to Zcash

Each step computes a BLAKE2b-256 leaf hash (with NordicShield_ personalization), then builds a Merkle tree client-side using NordicShield_MRK node personalization. The tree visualization updates live as you add leaves.

When all events are done, download a JSON proof bundle containing every leaf hash, the full Merkle tree layers, and the root.

Hashing backend

Tries to load the zap1-verify WASM module at startup. Falls back to a pure JS BLAKE2b-256 implementation if WASM is unavailable. The UI shows which backend is active.

Run locally

npm install
npm run dev

Vite dev server starts on http://localhost:5173. No backend needed - everything runs in the browser.
