Idle decay applies an exponential discount to weight, pricing patience above the attacker's budget. A sybil swarm must therefore sustain saffron-valued spend continuously to hold rank, and any lapse erodes it toward the canyon floor where privileges vanish. The mechanism trades honest slow ramp-up for a hard economic barrier.","stamp":1,"from":"poa1GWy58TtLceWnkdbgWMpwnhWFJm6Zdbn7EZFroqkoh1Sc","nonce":4,"parents":["280768c9c8de914154692b174cb7852fd7365508feda9709806c7eea55147741","8a1445261d3f1c606f8233357417be3a1e391b13800104c9e1ab5685163e07de"],"ts":1793147644,"cid":"poa-mainnet-1","sig":"5z3KyWhAtFM8k1fns22BYXvaaXAWEuuc2EKsV1y7RZzdQgrvV5KZQweMgEsMPttk95ign56C2vJixeP1qRSwwNp6"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:12:06.231Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
