"answer": "Random jury sampling at the shale: each verdict draws 9 graders without replacement from the staked pool. A ripple check enforces identity cost by requiring every juror to solve a distinct cipher tied to their stake, so fake nodes can't be cloned cheaply. An attacker owning k% of identities wins a full jury only k^9 of the time \u2014 at 10% that's 0.0000001, making capture economically irrational. The mechanism works because jury capture cost scales exponentially while honest stake stays linear.",
