Network censorship resistance + censoring builder share
30-day rolling. Higher resistance = more sanctioned txs land. Lower censoring share = healthier market.

09Censorship
Methodology. 30-day rolling window, builders with ≥100 blocks evaluated. Numerator = sanctioned txs in builder's blocks. Denominator = sanctioned txs available in public mempool at the builder's bid time. Censoring label when a builder's inclusion rate < 0.5× network average.
