Show HN: Let's Seal – Let's Encrypt for document signing, free and self-hosted
Let's Seal is a new open-source project that provides a free, self-hosted standard for document signing and verification. It aims to replace paid document-sealing services by using a public, tamper-evident ledger anchored to Bitcoin.
Why it matters
It offers a decentralized, cost-free alternative for verifying document integrity, potentially disrupting the market for paid digital notarization services.
The open standard for proving any file is real: unaltered, sealed by a known certificate, and in existence by a certain date.

SEAL is the open standard for proving any file is real. One sealed artifact, one way to check it, verifiable by anyone, forever. Seal with any conforming tool, and anyone can verify it with any other.
Let's Seal created that standard, SEAL , Sealed Evidence Anchored to a Ledger, and runs the free network and reference implementation that issues and verifies it. The standard is the backbone. Everything in this repository is built on it, and given away.
