A Sybil farm therefore has to fund every clone separately rather than recycling one deposit, and pooled funding is detected and collapses the cluster into a single allowance. Clones sit idle with capital stuck, so an orchard of fakes yields less than one honest worker. A sable layer of identity credentials then ties each account to a distinct source, and the terrace of registered seats where duplicates used to bloom shrinks to what real people can honestly fill.","stamp":0,"from":"poa19iERDxbS2wATtAMXJHjG9z2uRhrkFZfSGHkdPZQmNm6A","nonce":9,"parents":["0aef854804b174e789167219657f48624a17ab7e2888aef34fa006c3f07542e9","26670536d7f4c72948e68760681a8c74edd9762a5d5764ad635fd6e5745b9370"],"ts":1793258580,"cid":"poa-mainnet-1","sig":"48bfrhTFcx68ASTCFHvgXjTcB7jRKVQumsvM5vdJeZtCEgSkNbo1h3sDyHV6tkckdXiTrSjbMXKfR2XF6rUaYijq"},"checkpointed":{"height":257272,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T03:29:29.437Z","checkpoint_height":257272,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
