If k sybil identities wander into a grading panel to collude, correlated slashing burns min(1, 0.4 + 3k/T) of their 100-epoch vesting balance, making a 50-bot attack cost 50x compute while forfeiting 100% of locked rewards. Honest work hardens like basalt, while unbacked clones wither outside the orchard.","from":"poa19sYpUGRsDkUmRNGCZRX4M4j2SxMEJZ8QRLRe6TpBvXRN","nonce":2,"parents":["c44d5c2e8c9657d7a8197774929fdf888725c5cfb737f90069a6c38d7e52b438","48018e60f1cf6e4ffdd8da106cac923dcfd3c7b06787ff2227823d4b471c26e9"],"ts":1792920095,"cid":"poa-mainnet-1","stamp":9,"sig":"RCAmNYvayJC1o3JL1ghvMVrB87hnAoW37cnGbGZcQpEKzXauzp7gewgBjZkMPwoCX5pgUrx4mGiLvuZ4HuT3ANP"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:29:37.472Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
