Itys

Itys proof document receiving a cryptographic timestamp stamp
Private content becomes a durable, verifiable timestamp commitment

Private, verifiable proofs of existence.

Itys creates locally verifiable commitments for private content and agent worklogs, with optional Ethereum timestamps that never require uploading the original material. Its SvelteKit web app handles content proofs, while a Node.js CLI, HTTP API, and MCP server produce signed worklog checkpoints with selective disclosure. It proves integrity and existence—not truthfulness or completeness.
