BTC: Blocks by Mining Label

Bitcoin Blocks by Mining Label: daily data through 7 Nov 2026.

Canonical block counts split by their accepted mining-label category.

Why use it. Compare the distribution of observed block production across named and unidentified categories. How to read it. For a proved empty sealed interval, the absolute total can be zero without inventing a contributing label. The chart, the series API and the CSV/JSON exports select the 12 largest named labels by block count in the selected range and group the remaining named labels as Other labelled pools, with the same exact values. Unknown and Ambiguous stay separate. The paged raw-history download keeps every contributing label. The pinned label list is applied retrospectively. Tags can be spoofed, and different labels can belong to the same operator. Read label coverage alongside these observations. Read actual source coverage and clocks. Open periods remain partial; MTP closure and six later canonical blocks govern finality. The calculation describes unsmoothed observations; chart smoothing is a separate transform.

Calculation. Count each block once in its accepted named, Unknown or Ambiguous category; the complete component sum equals all observed blocks. Match literal UTF-8 coinbase-tag bytes with ASCII-only case folding, together with the exact canonical address of coinbase output 0. One candidate gives a named label, none gives Unknown and conflicting candidates give Ambiguous. Assign complete canonical blocks to UTC hours or days using their header timestamps, retaining timestamp regressions. Use locally validated canonical coinbase facts and the pinned MIT-licensed mining-pool definitions; credits and the dataset revision remain in method details.
