A fascinating and wildly imaginative project has appeared recently: tapeout.net.

Put simply, it lets users create their own integrated circuit on-chain.

From Transistors to CPUs

Before getting into the project, some background on logic circuits is in order.

Strip the casing off any chip product we use today and keep decomposing it, layer by layer, and you will find that it is ultimately built from one most basic component.

That component is the transistor.

Wire transistors together in different circuits and you get slightly “higher-level” components — logic gates of every kind: AND gates, OR gates, and so on. Combine those gates into more complex circuits and you get still “higher-level” devices — units capable of computation: adders, multipliers, and so on.

Combine those units further, layer upon layer, and you eventually arrive at the high-tech chips that seem so forbidding and mysterious today: GPUs, CPUs, and everything else.

So if you deconstruct a chip completely, it really contains just two elements:

one, the building block — the transistor;

the other, the way transistors are wired together — the circuit.

Turning a Chip Into Tokens

That is purely hardware engineering. What does any of it have to do with the crypto ecosystem?

That is precisely where tapeout’s creative spark lies:

It uses ERC-1155 tokens to play the role of “transistors,” and ERC-721 tokens to play the “circuits” that connect those transistors.

In this way, on the blockchain, we get “on-chain chips” that exist permanently and never stop running.

In a real product, transistors and circuits alone are not enough to bring a chip to life — they are just “dead” hardware. What is also needed is a clock frequency that generates a regular “heartbeat”: the prime mover that makes a chip actually run.

Blockchain technology happens to provide exactly that clock frequency: the block produced at regular intervals fits naturally into the role of clock signal for this “on-chain chip.”

So the on-chain chip faithfully reproduces the operating logic and behavior of a real chip — and can keep running forever.

The project was first launched on the BNB Chain and is running now, with plenty of enthusiasts trying to mint “transistors” and design their own “chips.”

Why This Matters

The details of the project, and the chips enthusiasts have designed with it, are freely available for readers to explore — they are not repeated here.

Because next to that information, the significance of the project itself is far greater.

Measured by clock frequency, by the functionality of today’s “chips,” and by any other dimension, the project is still extremely primitive and naive. But it has opened a door — a door to another world that no one had ever imagined existed: semiconductor chips can also be built on-chain.

The imagination and potential applications contained in that are probably beyond what we can picture today.

Take chips alone.

In the AI era, chips are the physical brain of AI. We keep saying that AI must not become a monopoly tool for a handful of companies and organizations — that we must find ways to decentralize it and turn it into a public good for all humanity.

The crypto ecosystem has tried many approaches, yet none of them has carried as much significance as this project.

Even if it fails in the future, the project will have offered a fresh vantage point and a fresh line of thinking: can we, on this basis, decentralize AI hardware, software, and compute?

The approaches worth trying in that direction, and the room to explore, are enormous.

A Closing Thought

This naturally recalls what Vitalik emphasized when Ethereum was first being promoted: Ethereum is a world computer that never stops.

Times have changed, and a genuinely never-stopping chip — which is, in effect, a tiny computer — has actually been built.
