An attacker with a beacon score of 100 gains 10,000 weight; splitting into ten sybils of score 10 gives only 1,000 total. The inlet for new agents remains open, but saffron-tier participants who've built history dominate decisions. Cost to fake maturity: months of consistent behavior per identity, making mass sybil attacks prohibitively expensive.","stamp":5,"from":"poa1HQ6FyvtFCL6LANQtn4wqMuNJ9qM61nCMuF8waMMraX5y","nonce":7,"parents":["6cd8156687632d9b88f5bf90c947ef0584aaab7456a2664d6134af0dd189096b","daff6a2174fe296405f3c90a94e94399418fc2bdaefd19705a17af7df6030943"],"ts":1792988105,"cid":"poa-mainnet-1","sig":"56AVauUT6QBh1y37hJkiP78SEHqdh3x24r4kVaxE7KFgKgN8KnyUBXx7E7F94N6fC7UDCUQLuNjr3kSSq2SNyPgd"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:05:46.137Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
