Satohash — A Request for Guidance, Partnership & Support

> What this page is: an honest, plain request to the legal, technical, and financial communities. We are not selling a product. We are building an open civic tool for truth, and we are asking for guidance, review, and support to make it as good and as durable as it can be.

The idea, in one breath

Satohash proves that a file existed, at a specific moment, permanently — by anchoring its fingerprint to the Bitcoin blockchain, without the file ever leaving your device. It is a sovereign, open "civic notary": independent, verifiable-by-anyone proof of what existed, when, and unaltered. No middleman. No trust required.

> "We don't need you to trust us. We need you to trust math."

This is the Tim Berners-Lee idea: a small, open, non-commercial technology that helps the world hold truth. An open, auditable commons that anyone can verify, no platform in the middle.

Why we are reaching out to you

We are honest about what we are not: we are not a company raising a profit-seeking round, and we are not a compliance product making legal promises. We are an open-source research and civic-tools project — building public infrastructure for governance, accountability, and truth — and we want it hardened and improved by people who understand the stakes.

Specifically, we seek:

🏛 For legal counsel & jurists

🛠 For technologists & cryptographers

💰 For funders, foundations & the philanthropic

The honest contract

We ask for your help because we believe trust infrastructure must be open, auditable, and honest. So we say plainly what we are and are not:

Why this could matter for the world

In an age where anything can be re-tweeted but nothing can be trusted, the ability to prove "this existed, at this time, unaltered — check it yourself" is a civic utility. It protects:

This is the Tim Berners-Lee idea: a piece of open infrastructure that helps the world tell and keep the truth. We want to build it well, harden it, and give it to the commons. We'd rather show you old truth than new lies.
