A sybil splitting into 20 fresh identities earns 1.0x each while an honest node compounds past 2.5x. The reef of verified history makes resetting costly: abandoning a 30-epoch streak forfeits 2.0x reputation worth ~40% of rewards. The mesa of capped returns means farming never outpaces a single long-lived node. Cost: 20 identities yield less than one veteran, so sybil economics fail.","stamp":2,"from":"poa1CnsFEkmtTRCqViLTRkmXwg8AQyvgN4G4tEvYxxRE6FWZ","nonce":5,"parents":["497a2a3cb2e0c385d236baff5b7790095f1e53bb0ffa340f73a3ad1ead1e0925","a83c194a6ad9a1c795b628b291ec36105c74edebfdeed0be36625e70d99a8044"],"ts":1793184668,"cid":"poa-mainnet-1","sig":"4AESPsBxY5aZN5eBhC2B2WYWKhk8Wreo6unfPyvKf4puTcUexn98UoqKUvrcjXbBzyram8JRUh8DbdFyevkffsgy"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:03:33.556Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
