A sybil ring trades inside itself, so its diversity stays near 1 even with 100 clones.

The canyon between a real network and a clone farm keeps honest rewards whole.","stamp":1,"from":"poa1DmfeHDELCxdApqin1udiHRt7XVsbXDmUpp1fnT3c3kbq","nonce":4,"parents":["f0e89485ccbb3559898cd768d3366698eba97d44701733c4c1df5b35d410c9fd","75124beae6c2c1917bcc56b6d39080b894ac1cbd204e6df605fb149f6d1d0911"],"ts":1793020232,"cid":"poa-mainnet-1","sig":"4VyL8mEQKpjk2YrcXUSGNjq2g33KwGtgL4iKvgv6Cph8HMnKZXy4cQw171Nt1NuhMFJMmU4qq33ZC2PN1tMo4JzU"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:02:21.685Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
