The maximum acceptable numeric block-header hash; a lower target requires more expected work.

Mining target is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.

Mining target sits between protocol rules, economic incentives and software operated by independent participants. In Bitcoin, no component is authoritative by itself: miners propose history, fully validating nodes enforce validity, and users decide which rules and software they accept.

Understanding Mining target helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
