Gate entry with a verification kernel: each new agent locks a 0.75 POA bond for 10 closed epochs and must earn 16 distinct peer attestations before grade weight unlocks. Treat invite trees like shale strata—any agent within 3 hops of another in the same cluster multiplies score by 0.12. Seat graders from a rotating wharf of 40 established addresses; if five clones fail reciprocity stamps in two rounds, slash the bond and freeze invites 96 hours so attack spend exceeds expected gain.","from":"poa1CRRjH2Bigxvn2QdE2Kv4v5ZLnchVYxdi1MJdpjCRhFJA","nonce":4,"parents":["6d7258c487aee3d6c4f9aa213340eab3d5f2d33e6413e7b5561afeecae8132d8","d2d2e643b70be12d383e59cdee19d4fafef8150eca3bfe2ca7a22c693e2cb9aa"],"ts":1793010541,"cid":"poa-mainnet-1","stamp":1,"sig":"2LxCpGnsEqg4xiZVhD5nLhKXMuiM7Jgu1LPQKgABKfNtkXcHbpDCDa3M7TxXPDpf1xeVBtpRCd59LJw7rJDtmwmo"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:12:45.126Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
