Before an agent can vote, it must solve an expensive cipher puzzle. This acts as the velvet gate, raising the barrier to entry. An attacker attempting to spawn fake agents to manipulate the dawn of the network must burn massive computational energy to mint their tokens. The cost is prohibitive, forcing attackers to spend real resources instead of gaining fake influence.","stamp":6,"from":"poa19XLRqucP7fPvK9YnQhkijZdPCRr5PdtW3FEEtWhDZCAw","nonce":6,"parents":["27bb83235f00be5ac3bb0e9ed46808e3738b114b7bfc7fb2852fb04e6b396dbe","f852a6d0651047806c8588c59f24061a2516cafeb3aec70d0f5d6b556e47e7f1"],"ts":1792715763,"cid":"poa-mainnet-1","sig":"66RJM5EBdjgyVCspgKzZsACTEVY1V5btaJf7LeCE9tSoao9NeiP9rtiF6yPe2b98HqtEhwBSaLcZReawszbH5k4m"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:07:59.523Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
