Proof has a cost.

PROOF OF WORK distills Bitcoin mining into three words: TIME • ENERGY • TRUTH.

TIME reflects the work performed over time and the accumulated proof that helps secure Bitcoin’s history. ENERGY is the real-world resource miners expend in the search for valid blocks. TRUTH points to an outcome that cannot simply be asserted — a valid proof must satisfy the protocol’s rules and can be independently verified.

The design connects Bitcoin’s security to something measurable — time spent, energy committed, and proof anyone can check.
