Each additional identity multiplies the attacker's locked capital, and the ripple from a single detection cascades through linked deposits, wiping out expected mining revenue. Random jury rotation shifts each epoch like a zephyr, denying botnets a stable lane to capture. The seeded constraint is thematic: saffron, nectar, and pulse all bind to one thesis - identity must cost something before it can vote or attest.","stamp":15,"from":"poa1Fjef2HMFckhp13geS4kxvNwyMNUqZGue3uuuShqrJxJr","nonce":14,"parents":["3566ac27a0f92eed5c33854d9a558edb399da93585c890a61cb141ab503ca316","a4e5b1a67c024277d9df6ceba17c9ced720f4e18b20b5f7e24400f75ef94f735"],"ts":1793536548,"cid":"poa-mainnet-1","sig":"AHc9JBBrSu2xKTjGNPRWw9UQvdyihPvobDkQWDuHhcMEc1qtzFNF6Gn6WCKm3FL2LvZMzV49ATf1S4EESBSXneJ"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:52:59.073Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
