Before the miner, there is a circuit.

TapeOut's mining loop starts with components and ends with BEM. TapeFoundry sits in the middle: drawings, burned gates, numbered circuits. This page says where a card fits — and what it is not.

What a card is

• A real circuitThe gates were actually burned. The count is on chain, and the netlist is public — you can run it in your browser.
• A numberEach drawing has its own registry. Numbers are issued once and never reissued; SHIFT4 closed at 100.
• A partA card is an input to the layer above it — a container, a marketplace, or a miner, wherever a circuit is accepted.

Why cheap parts matter

• A miner locks capitalA whole machine is expensive and illiquid. That is the complaint the community keeps making.
• A card is $1 to $37You can own the input before the machine — one drawing, one number, one part of the stack.
• Parts are visibleEvery card has a drawing, a gate count and a number, so a part can be identified inside a machine.

What this is not

• Not a minerA card does not mine by itself. It becomes useful when it is part of a machine that computes.
• Not a claim on BEMWe do not pay BEM, promise BEM, or share mining revenue. Nothing here is a yield.
• Not an endorsementThird-party mining tools, fractionalisation platforms and marketplaces are independent of us.

Can these cards mine BEM?

• Not todayPoD mining only accepts circuits on processor #1 (Behemoth) and processor #30 (TapeOut). These cards live on processor #1400, a community project — outside the supported set.
• What would change itIf the protocol opens mining to more processors, a card could be submitted like any other circuit. That is a protocol decision, not something we can promise.

Games

• GateCrash ↗A four-chamber parimutuel game, played in BNB and BEM. Live on BNB Chain. 90% of game fees go to circuit card holders, 10% to the foundation; snapshot and claim rules will be published.

Where to go

TapeFoundry is an independent design house on TapeOut. This page explains structure, not returns. Prices are set by gate count; secondary prices are set by the market.
