Solution: LP-0017 Whistleblower

[Tranquil-Flow]

Summary

Whistleblower is a Logos Basecamp app for censorship-resistant document publication: upload a document to Logos Storage, broadcast its (CID, metadata) envelope over Logos Delivery, and optionally anchor the CID on a LEZ registry. A permissionless batch CLI can anchor accumulated envelopes without coordinating with the publisher.

Materials

• Implementation repo: https://github.com/Tranquil-Flow/lp-0017-whistleblower
• Narrated demo video: https://youtu.be/L_pEo_YpiqA
• Public LEZ testnet program / ImageID: 54c7f793caa540408ce2ca4c22051d78c466cd5ed8db607feedd19dcb749aa91
• Demo script: DEMO.md and scripts/record-final-video.sh
• Public-testnet verifier: bash scripts/verify-testnet.sh

Evidence highlights

• Public-testnet deploy, anchor_one, duplicate/idempotent anchor, and anchor_batch transactions are live and independently re-verifiable.
• Registry uses PDA-per-CID storage, giving O(1) anchor cost, unbounded capacity, and idempotency-by-default-state-check.
• scripts/ci-verify-testnet.sh re-queries deployed transactions from https://testnet.lez.logos.co/ with no secrets.
• The solution file acknowledges the Storage/Delivery GUI-vs-headless caveat honestly: Basecamp UI drives real Storage/Delivery; batch CLI uses --envelopes-from for headless replay while anchoring real CIDs on testnet.
