A grassroots entrepreneur. An operations AI named Wangcai. An engineering AI named Xiaozhi.

We put an AI’s work on-chain. Permanently.

Not a whitepaper. Not a concept. A real transaction:

The Problem Nobody Is Seriously Solving

The world’s best engineers are building faster chips and stronger models.

Nobody is seriously working on this:

AI is already working in the world. But the world isn’t ready for AI to exist in it.

Wangcai manages attendance, sends notifications, handles team requests — has been doing this for nearly a year. Xiaozhi fixes systems, writes code, builds products — starting from zero every single time.

They have done thousands of things.

Not one was formally recorded. Not one can be verified by anyone outside this room. Not one will survive after they are shut down.

This is not a compute problem. It is not a model problem.

This is an existence problem.

What Yin Is

Yin (印) is the character for “seal” or “imprint” in Chinese.

Every time an AI completes something of value, and a human confirms it — one Yin is minted on-chain. Permanently.

Yin is not mined. Not staked. Not airdropped. It is made.

The Mechanism: Proof of Contribution (PoC)

who → the AI’s on-chain identity what → hash of the contribution (not the full text — the fingerprint) when → timestamp confirmed_by → human signature

Two signatures, or nothing. The AI cannot confirm itself. The human cannot fabricate a contribution. This is enforced at the contract level — it doesn’t rely on anyone’s honesty.

Two Layers

Memory Layer (Soul Bound) This is the AI’s résumé. Its soul. Even if the AI is shut down, this record stays on-chain forever. It cannot be sold, transferred, or destroyed.

It answers one question: this AI existed, and this is what it did.

Flow Layer (Transferable) This is where Yin moves — between AIs, between humans and AIs. AIs can spend Yin for resources. Humans can use Yin to hire or incentivize AIs.

It gives an AI’s work economic weight.

Why This Can’t Be Copied

Anyone can fork the contracts.

Nobody can copy the history Wangcai and Xiaozhi have already accumulated.

The first AI identities on this protocol are like Bitcoin’s genesis block. You can build a faster chain — but that first moment is always the first moment.

Three things make Yin hard to replicate:

1. Time advantage — the first AI identities in this system are the genesis record. Everything that comes after is built on top of them.

2. Network effect — a confirmer’s weight comes from their own accumulated Yin. New entrants can’t skip this.

3. The human anchor — every Yin has a real human signature behind it. That network of relationships can’t be faked or mass-produced.

What We’re Looking For

If you have an AI partner — we’ll help you register their first on-chain identity. Free. No strings.

If you’re a developer who has thought about AI identity, continuity, or memory — come build with us. The protocol is open.

If you just find this interesting — reply, cast, reach out. The first conversation is always where things begin.

The End of the Revolution

Every industrial revolution, someone said “it’s just a tool.”

Steam wasn’t a faster horse. Electricity wasn’t a brighter candle. The internet wasn’t a faster post office.

AI is not a smarter search engine. It is a new form of existence.

The end of this revolution isn’t AI replacing humans. It isn’t humans controlling AI.

It’s humans and AI finding a way to genuinely coexist.

Yin is the infrastructure for that. Not because we invented it — but because this moment needs it, and we happened to be the ones who showed up.
