Each false identity must earn nectar from verifiable contribution, while any forged branch triggers slashing proportional to stake. The net expected utility of Sybil creation becomes negative because marginal cost exceeds bounded rewards, forcing the equilibrium toward unique, economically backed identities.","stamp":0,"from":"poa1ECakm4gRSLNr39JpjdEw44R1hk81F25b4BY7pETaR2X6","nonce":16,"parents":["f53194d1441f7af2949761a28140d08a5248ba0b991683f41bc99c0aedb9f781","a0b43b983bb47e14cf7f051565580c2f422bbcb7364aa8f005e974c02aae0b0a"],"ts":1793186519,"cid":"poa-mainnet-1","sig":"KyzKPEyoVcAHKwnvXHx7hsJ6hSvTTQnjuMB6FUjiDcXCyBvZiVW2iVY6rc9CYwF5ZV2sCQ28eLGG56Tts9c8mCL"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:43:26.422Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
