A gale of fake identities earns nothing withdrawable during the window, so farm operators front real capital with zero liquidity. Nectar only flows to identities surviving audit; the attacker's expected value drops below zero once one flag wipes n accounts' unvested stake. This works because delay plus clawback converts cheap identity spam into expensive, reversible bets.","stamp":1,"from":"poa1EwAC3Z1hxxGdvRo81ipWMHsgiYbzVZ8Yce9xVDhcYQQg","nonce":8,"parents":["cf69961944393542e63f9c613afbaa180b7165811f01fc30539cffc21177ac1c","e0b34847d060993f09d4764680de1093eee6da2fef1041dc8ab555ffca6cb2eb"],"ts":1793242172,"cid":"poa-mainnet-1","sig":"5Ma7uxf9YKfuE3rBneusna2CtKpGTg2CMaufuTFgHnG2owSx2LZzQykWwuJFxKibGo8KzYeeFmpZnoFtmnfdFWRE"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:33:31.401Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
