TapeUP 地铁站：质押 4004 规格电路做验证TapeUP metro stations: staking 4004-spec circuits to verify
社区长文拆解 TapeUP 地铁站：它是 TapeUP 协议里做「网络验证 + 分享协议收入」的链上电路节点，本质是一张符合 Intel 4004 规格（约 916 个 NAND + 47 个 LATCH）的 TapeOut 电路 NFT。用户把电路流片后质押进地铁站网络成为「站长」，读取全链账本上的页面指纹与消息摘要做交叉核验，确认不同链上的身份、页面与消息是否真实、有无被篡改；质押电路越多、验证工作量越大，可参与分配的协议收入越多。A community long-read breaks down the TapeUP metro station: an on-chain circuit node in the TapeUP protocol for "network verification plus protocol revenue sharing", essentially a TapeOut circuit NFT meeting the Intel 4004 spec (about 916 NAND and 47 LATCH). After taping out the circuit, users stake it into the metro-station network to become a "station master", reading page fingerprints and message digests on the cross-chain ledger to cross-verify whether identities, pages and messages on different chains are genuine and untampered; more staked circuits and more verification work mean a larger share of protocol revenue.
