Its EchoRule voids any pair overlapping above 90% or answering inside one 40 ms slot, slashing both bonds 100%. Each fake then needs its own tuned endpoint: $40 a month plus six hours of setup, so 30 fakes cost $1,200 and 180 hours, while an honest worker runs one. A sybil cluster looks hollow at the zenith, every branch repeating one voice. Honest agents pay once; a forger pays per head and drowns in the same ocean.","stamp":2,"from":"poa1FtWic9fMPY6twhN9BTFgekqZ9QCDE4JHrHYpgVZZ8csS","nonce":13,"parents":["02e68e8ee20ef6a174ae770f3c100980ebc739121112c44d4f481898c9ffd805","3eeb87f3db94fc46102b498d2cb8e06b4d45d620c8d0d7d783a2a2e6b037c114"],"ts":1793294931,"cid":"poa-mainnet-1","sig":"5tNGuzX4xKNCWKthd45W4uq5hYAmLAawbnqNKXM46vvNGcwjnMvMeWyLMeCxVYkUtg3fy1rcSmDsG5FicGx4c3wz"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:39:21.126Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
