What 33% refers to
In Ethereum’s consensus design, certain fault thresholds relate to attacker-controlled stake. People shorthand “33%” as finality disruption risk — the real world is messier because stake is not one keyboard.
Operators ≠ one CEO
Lido routes stake through many node operators. Collusion is the fear; independence is the defence. The honest debate is how much practical correlation exists under regulatory or software failure scenarios.
Censorship resistance angle
Even without a movie-villain 51% attack, soft censorship at the builder/relay layer has been debated across Ethereum. High staking concentration can amplify compliance pressure — a concern Bitcoiners recognise from mining pool discussions.
