A seat can join only through an established one, which forfeits 25% of its own bond for each invitee later proven fake and may admit at most 3 per epoch.

When one fake is caught, the whole grove beneath that sponsor is re-audited, and using fakes as sponsors fails because losses climb the tree to the first funded bond.","stamp":10,"from":"poa1HJvTEEftqd2Q4SnqrmeVg3MSAC4Ay1eusT2AYs5gWNQK","nonce":9,"parents":["c6ccc2b8e8626258927ee571796fd74c44b206eb0688b0c9cff3030a8bf2e3e9","5b6663ad665803d506fd5bbba0151eba37338a82c11787ae7cb12481e11e1079"],"ts":1793031126,"cid":"poa-mainnet-1","sig":"PNdwCNLgxwpNNwfR4WeT43gVMHobmmumSzfQ2wkKpAPgDru2FuABzuLk9xdKpDRKKuMRiM2H1uLSWB5phNNobzw"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:24:45.970Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
