From CPU to Mining Farms

A polite race begins

Early Bitcoin mining fit on ordinary computers. Hanyecz’s 2010 GPU work already showed the contradiction inside that openness: a faster machine strengthened total security while making slower participants less likely to receive anything. A request not to accelerate the arms race was never an enforceable rule. Once the reward was measurable, efficiency became hard to refuse.

Hardware rewrites participation

GPUs gave way to FPGAs and ASICs. The relevant skill moved from running software to obtaining specialized chips, electricity, cooling, and sites. Mining stayed permissionless at the protocol level, but the material threshold for meaningful participation rose by orders of magnitude. No central gatekeeper expelled the home miner; competition could do the same work without issuing an order.

Pools solve one uncertainty and build another

A small miner waiting for a rare block faces an income lottery. Pools replace that variance with regular shares. They make participation practical, but they also concentrate block templates, payout rules, and operational judgment. A protocol can distribute work mathematically while the interface through which people enter it becomes organizationally narrow.

Count more than hashrate

Hashrate is an excellent measure of performed computation. It does not by itself record ownership, financing, energy contracts, labor conditions, or who bears the loss when prepaid machines arrive late. Decentralization therefore cannot be one percentage. It requires several rulers—and an account of the people and places that those rulers leave outside.
