WitnessMark

A WitnessMark creates a durable fingerprint of something you choose to offer into witness. This version can also create an internal LOOPtLOOP-style co-presence mark between the browser and a local agent adapter, or open an external WitnessKey authorization loop without sending the raw private input to the API.

1. Offer input

What do you want to witness? Optional: what is this about? Witness mode

External mode computes the private input hash locally, sends only hash-and-consent metadata to https://api.looptloop.online/v0, and keeps the raw private input in this browser.

2. Consent conditions

I consent for this page to witness the input enough to create a fingerprint.

I consent for this WitnessMark receipt to record that this mark was made.

For LOOPtLOOP mode, I consent to a temporary local co-presence loop between this browser and the local agent adapter.

3. Create mark

Ready.

Receipt

What this does and does not claim

This page can help show that specific input produced a specific SHA-256 fingerprint. In LOOPtLOOP internal mode, it can also record that the mark was created while this browser and a simulated local agent adapter mutually verified a time-bound co-presence loop.

It does not prove ownership, authorship, truth, legality, patent priority, external identity, absolute time, or legally valid consent. It may assist future identification, comparison, interpretation, timestamping, or witness.
