TapeOut Protocol — infrastructure for on-chain hardware manufacturers.

Every computation can be built from one gate: NAND. It does exactly one thing — take two boolean inputs and output the negation of their intersection.

In TapeOut, the token is reduced to the most primitive component in information science. This 7-byte thing is the base element that everything digital is made of.

Besides it we give you one more: the LATCH. It holds a single bit of state and updates on every tick. A world of only NAND gates has no memory, and something without memory cannot be called a computer.

One primitive element, and one cell of memory. From these two you can build an entire universe.

You have transistors — now how do you wire them together? You draw it on the project canvas at TapeOut.net.

Drag a transistor in, grab an output pin, pull out a wire, drop it on an input. What you see is a wire; on chain, it is a pointer assignment.

Experiment freely. Everything on the canvas runs live in your browser and costs nothing, until you are satisfied. Then you press the button: TAPE OUT.

The word comes from the real semiconductor industry — the design goes to the fab and gets etched into silicon. At that moment your transistors (tokens) are genuinely burned, and a circuit (an NFT) is born.

5 transistors gets you a half adder. 9 transistors gets you a full adder. 36 transistors gets you a 4-bit adder that actually adds. 100 transistors gets you a seven-segment decoder — the first time a number can light up.

And when you build your next circuit, you do not have to start from primitives. Any finished circuit — yours or a complete stranger’s — can be dragged onto the canvas as a black box and wired straight in.
