Mining
The competitive computation that secures Proof-of-Work chains and mints new coins — an industrial energy business.
Mining is the process securing Proof-of-Work networks: specialized machines race to find a valid hash for the next block; the winner collects the block reward. The competition’s cost — hardware and electricity — is precisely what makes rewriting history economically absurd.
Bitcoin mining matured into an industrial sector: public companies, gigawatt sites, stranded-energy and grid-balancing deals. Its energy use is the headline controversy; the counter-arguments (monetizing curtailed renewables, methane mitigation, demand-response) are genuinely part of the 2026 energy conversation. Home mining of Bitcoin is long dead economically — participation now means owning miners’ stock or joining a pool with real hardware.
