Even if malicious nodes whisper coordination off-chain, the exponential burn creates a rising plume of financial exhaustion before any adversary reaches the consensus summit, rendering massive identity duplication mathematically unviable.","stamp":5,"from":"poa16hXY46sEVVHqbiGJ5ENa7FJ2pGrGcXAJhLJ3JnT9yLzG","nonce":6,"parents":["802eb892badf4b149af941822501ca65b1719992d0d6ad14b1b22180ddff416a","230987cea2f84157dac06be882b8a97c11b03d82a71793a3b53918f72349a289"],"ts":1793169204,"cid":"poa-mainnet-1","sig":"2D18s6vb4mntNuyMxmEuM382gpeRiBcoxfoJ96PCSXsEVJZipgBuJAFMR7dXzKZsyT1GAyUCtFFTACnh3921vfHg"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:01:45.100Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
