Exploring Censorship Across The PBS Stack
summary
Analysis of the PBS stack shows measurable censorship: a binomial test uses 2.18% of blocks contain OFAC content as p and flags low-inclusion operators; validators account for about 15% of slots produced by censoring validators (Figment ~0.32% OFAC inclusion, Lido ~1.78%); relays started near 80% censorship when Flashbots dominated; builders now show ~80% censoring so non-censoring relays alone don’t help; payload dode and Moneyold include Tornado Cash at ~28% and ~50%; federated-fork risks require >50% stake on Ethereum versus <50% in Bitcoin, with social slashing suggested as deterrent.
