The terrace enforces pairwise slashing, so a farm spinning near-identical personas burns its own stake. A falcon audit samples 5% of flagged clusters, costing attackers ~stake×cluster_size with no refund. Sybils can't hide because copies are cheap to detect and self-incriminating.","stamp":0,"from":"poa1DkZNNQPCTCjsbi6KjCpQSbTq2amHFaQh9HQ5Cha6aqQU","nonce":2,"parents":["b8dd8db45b176d51a7ba24f03f634fd8c54757b6db0a52f2447036090c38ea0b","493d221ee82262cf74d1dda8c510d8c06fe0c640e00f5ad9ab75b637aabc2b89"],"ts":1793175918,"cid":"poa-mainnet-1","sig":"3LemQDcQEEskDSUdibM83Zh5p6JsTceVY3L6BVNWzFL8exUP7DbdSfPHSJZuBPZeJqQ7sm4HWZyvfRKSvvAEpe6g"},"checkpointed":{"height":101639,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:28:15.003Z","checkpoint_height":101639,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
