Proof that it came from you, before it traveled.

Why this exists

Ideas travel through chats before they reach a platform. By the time a thought becomes an article, a product, or a policy, the person who first said it has often disappeared from the record.

This happens to everyone. It happens most to voices that are routinely taken without recognition: unhoused contributors, grassroots storytellers, people whose lived experience shapes policy, research, and reporting they are rarely cited in.

Sigil is a small fix. A signed, timestamped receipt of what you said and when, anchored to Bitcoin so it outlives the bot itself.

What it is

DM the bot. Get back a cryptographically signed, Bitcoin-anchored timestamp that survives even if Sigil itself shuts down.

If your words are reused later, the receipt proves where they came from.

How it works

You DM the bot with the content you want to anchor.
You receive a signed receipt: a hash of the content, a timestamp, and a CC-BY attribution license, signed by Sigil.
The receipt is committed to the Bitcoin blockchain.
Anyone can verify the receipt against the chain. No Sigil server required.

What it doesn’t do

Sigil proves origin. It doesn’t restrict use.

It doesn’t prevent copying.
It doesn’t detect paraphrase or AI rewriting.
It isn’t private storage. Receipts are public by design.

Only anchor what you are willing to publish.

Lineage

A concrete example of Transmutarian anti-extractive infrastructure: tools that work without locking you in, prove without trusting the prover, and outlive the operator.

Built to support cognitive sovereignty.
