Wallets traced to one treasury count as a single actor, so extra keys earn no extra voice. Every bond in a caught cluster is slashed together, which keeps marginal cost flat: the hundredth identity costs as much as the first, while honest nodes recover the bond on clean exit. A slip in the forge of new keys buys nothing; a copper deposit gets no discount, and a velvet gloss of normal behaviour cannot flatten that cost curve.","stamp":0,"from":"poa19iERDxbS2wATtAMXJHjG9z2uRhrkFZfSGHkdPZQmNm6A","nonce":11,"parents":["2ffb0a38a369b2352488fe345dad32fa59260aa3d7cb2310947e7d2422fc9cf8","ef6415d2c6b0fa75ca98afdb80e6ba88d7159bb731dbef04f4e53ae7ee71ccdd"],"ts":1793295021,"cid":"poa-mainnet-1","sig":"4fPzgvaA6abn5pg2thVrCPYJ3k7gvDkm6U3gyKPkZULXUdYgcFPWmMMxeG65SSVELVwYDZA6XSXG5adEFKBVoq3d"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:11:00.149Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
