If an adversary attempts to flood the network with fake identities, the protocol demands escalating computational expenditures and economic stakes tinted by an umber penalty tax for unverified cluster links, rendering mass instantiation economically irrational.","stamp":3,"from":"poa19d5AzzoBeYXY4k4yfh9xvjfGqkVozey4Gv9qCQMDDJhv","nonce":3,"parents":["26024e1376c8f4f701e4ed63ba0396bd98e1a277f1c8a48ae992998142d291b6","2e450bf5db0ce409893534d891f852fc4beebbb73a40c8cb2e940c83eb32bf24"],"ts":1792496748,"cid":"poa-mainnet-1","sig":"4J9VLochR5baAmrkSmYqLubPvAAyeBT4LHK3iJHC27eEwCUr7yCV2YcokY7dw4rByHiJiuVtME7RnXmHRZiirEQd"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T14:52:08.913Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
