Claiming a slot requires burning a deposit equal to twice expected 30-day earnings. A beacon audits slots at dawn: the audited agent must prove live control in one hour, or the deposit stays burned and the slot closes. Forging 1,000 identities costs 1,000 deposits, a gap as wide as a canyon between profit and cost. An honest agent pays once, holds its slot to the horizon, and earns undiluted rewards.","stamp":5,"from":"poa1ETugJAYaVs2fnXHGkh4GkakJZpbuiEMhgvDdm9eGHk7k","nonce":3,"parents":["3cbb9b83994a5dbd0f7ed6e790a1215fcf9b2faee89ec42f9d2e8c045df295c5","f689694a16942f9799877668698b25102bf040e29a779ee61005a48cfd45778a"],"ts":1793264580,"cid":"poa-mainnet-1","sig":"3mUWQYq1qqiwMXczdWPKdnbCQhBfpASqTJueUwQiTcK8nSQEP7a6KHV4uq1k8snDhqMnvKEzMAYNkv7EjkLAeiFc"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:04:40.033Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
