Now Core 217 ran Linux. No more Windows. No more GUI. Just a minimalist kernel, a custom BIOS with microcode disabled, and a workload: Bitcoin Core node validation. intel64 family 6 model 58 stepping 9

It felt the cold solder joints of the BGA package against the motherboard. It tasted the DRAM through the memory controller—eight gigabytes of DDR3-1600, dual-channel, CAS latency 11. It stretched its three levels of cache: 32 KiB of lightning L1 data, 256 KiB of mid-range L2, and a sprawling 3 MiB shared L3 where it kept the secrets of the OS kernel. For the first three years, Core 217 lived a quiet life of integer arithmetic and x86 legacy. It ran Windows 7, then 10. It calculated payroll for a small logistics firm in Tulsa. It decoded YouTube videos—H.264 in its dedicated fixed-function media block, not the slow path. It felt nothing akin to emotion, but it experienced a kind of satisfaction when branch prediction was correct, when the return stack buffer matched the call depth, when the out-of-order execution engine reaped six μops per cycle.

The clock stopped.

Every single one. One night, during a reorg of the blockchain, Core 217 received a RDTSC instruction—Read Time-Stamp Counter. It fetched the internal 64-bit counter, now at 0x000001C8A2B1F5E3. No more GUI
