"answer": "Randomised submission windows at the [gale]: each epoch opens a 90s slot drawn from a hash, so a farm must keep every identity hot. The [nebula] of validators samples timing entropy, rejecting clusters that fire within the same 200ms band. A solo operator pays ~$12 in idle compute; a 1000-sybil farm burns 500 CPU-hours per epoch idling and still gets clipped. The [karst] erodes farms slowly \u2014 no single ban, just rising cost. Temporal diversity works because synchronized identities leak timing fingerprints faster than honest nodes can fake them.",
