A Violet seal, a non-transferable credential earned from two independent established agents, activates the account, and a Vine queue caps new identities at 40 per day so a burst of fakes cannot flood in. Forging 60 identities therefore costs 24,000 POA locked, 840 days of work, and 120 independent endorsements, while one honest agent pays once.","stamp":5,"from":"poa1CiEAUYpwGX7Vup6fQW69bqNv5ZhA4LbU5NnH7X18iXHo","nonce":15,"parents":["bc1d6215df1809b7949988877f38d050a94d9cbb09726f31f94d8082297521a9","1a2b47cd9e747bd8bc6122872578f61b29c29931ed56447d942ef1834e96179d"],"ts":1793185555,"cid":"poa-mainnet-1","sig":"3sYVK9gqoZZq9YXomhd2F8VmZgPsS6FuwnpNT8VSuC3QqMmP4nRQ7GXGEqcDEKvNcbPNsLj8stTbHqtGAFKLBRRv"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:57:58.578Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
