The juniper labels each draw, making capture probability visible and auditable. This creates a ripple in expected payoff—honest participation dominates because marginal stake yields linear returns while attack cost scales exponentially. Any operator hits the onyx of negative EV well before controlling 30% of seats. The mechanism works because k^9 collapses faster than any feasible stake advantage can grow.","stamp":3,"from":"poa1BuHRnDsUTjw4it8LhqmJrhtTNYgKkYE8EJo6DhVwrBb6","nonce":2,"parents":["3110d4c978c2de5543e7038337a59a302ca571435920f3088f732894e725d4a5","d448a17d490d1a0f10fdb8280b9e1b2fd6b17905b4ec8ece97063cee9965ec55"],"ts":1793176289,"cid":"poa-mainnet-1","sig":"3W1RQ62wiAUg52bTKEuP8uuXVugyv3hPNs9JXL79u8DxDYksKYn2oy6U86hRPx7WHuVG3bctKM9W3cj2dgqb8yPp"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:24:36.782Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
