Witness

Witness is a GenLayer attestation protocol for source-backed claims, verification, challenge handling and reputation.

This repository is a public proof package: it includes the product UI, the deployed GenLayer Studionet contract source, deployment metadata, finalized smoke transactions, and test evidence. Local wallet secrets are not included.

Why Witness Exists

A GenLayer attestation court. Users submit public claims with primary evidence; the contract scores sources, verifies claims with validator-agreed web/LLM reasoning, then supports challenge windows, appeals, finalization, archival, reputation and audit logs.

The frontend keeps the original product experience, while the contract adds a reviewable on-chain lifecycle: source records, GenLayer reasoning, challenge and appeal paths, indexed reads, and an audit trail that can be inspected after deployment.

Architecture note:

Witness V2 (# v0.2.16), 38164 bytes, 15 write + 23 view. Objects: Attestation, Source, Context, Verification, Challenge, Appeal, Reputation + AuditEntry. Lifecycle SUBMITTED->VERIFYING->VERIFIED->CHALLENGE_WINDOW->APPEALED->FINALIZED->ARCHIVED. DynArray[str] stores + TreeMap status/attester/subject/attestation-source/context/verification/challenge/appeal/audit indexes + recent ids + clock. GenLayer nondet (web.render + exec_prompt inside eq_principle.prompt_comparative) for claim verification, challenge rulings and appeal rulings; strict JSON normalization, confidence/support/dispute bps, source credibility scoring, URL validation and prompt-injection guardrails. Backward-compatible attest/verify/get_attestation/get_attestation_count/confirmed_count keep the existing static app working.

Static frontend bundled for standalone Vercel deployment

Frontend

Witness ships as a standalone static app:

• wallet connection through the bundled browser client
• GenLayer reads through genlayer-js
• writes routed through the connected EVM wallet
• bundled shared/ client files keep the Vercel deployment self-contained
• deployed contract address pinned in app.js and deployment.json

Run Locally

From this repository folder:

python -m http.server 8080

Open:

http://localhost:8080/

Deploy

npx --yes vercel@latest --prod --yes

Repository Safety

This public repository intentionally excludes local secrets:

• no private keys
• no vault files
• no .env files
• no .vercel project state
• no local dashboard data

Public files include frontend code, contract source, deployment metadata, tests, and non-sensitive proof links.
