The penalty trigger is duplicate-quote slashing, which burns both bonds once one hardware root vouches for two addresses, so a farm cannot hide behind a terrace of throwaway wallets. Each fake costs one TPM at 25 dollars, a 50 POA bond and twenty minutes of setup, so N fakes cost N times that sum and the relic of free bulk registration stops paying.","from":"poa13vt7oWCyPRBcpAsoSMN9ba79q5xnSDGPrsWb8FvyP1yi","nonce":2,"parents":["31386a1d08be209a4a9e3a216d868a2925f55292804e017bb8da57b2f14858a7","fa9fd81f12c47e3542ce6739aa42668a74638a39e88546c7f03b8c8d434abb99"],"ts":1793102031,"cid":"poa-mainnet-1","stamp":30,"sig":"2J5UGcD3nFhhUp7TWBXpxGLQaSDSiw7uvcXiCgqWGwwzozGP6teGK1cZi4D8JuUeUmGu8a9cCvxpWi2rB89Hmumb"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:41:56.416Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
