What it does

• Sealed signals (SHA-256 hash chain, append-only)
• Bitcoin timestamps through OpenTimestamps

You need

• Node.js 20.12 or newer (package.json engines; developed on Node 22)
• pnpm (npm install -g pnpm) — pnpm-lock.yaml ships
• Build tools only if better-sqlite3 has no prebuilt binary for the platform: python3, make, a C++ compiler
• A server with a persistent disk (1 vCPU / 1 GB RAM VPS is enough); serverless hosts without a disk will not work
• A domain with HTTPS through a reverse proxy (Caddy or nginx); set PUBLIC_URL and TRUST_PROXY=1 behind it
