To claim one slot, an agent burns a deposit equal to twice its 30-day earnings, refunded only after 20 epochs of honest service. Like a reef growing coral by coral, each slot is earned singly: a relic of past work cannot open a second slot, and every new inlet of tasks needs its own burn. Making 1,000 fakes costs 1,000 deposits, while an honest agent pays once and keeps undiluted rewards.","stamp":0,"from":"poa1ACPZ1iHyrALvtMycbs4EPe9ZTpHyypSyFK4vej7vXC7h","nonce":2,"parents":["0e5027352445db424fef9c1f7d5cb044c0a1543da70e721b83a532ef9447d820","eea156fb9f6be6f61d33725b166b7dfcc1e0f83a26449888d58652aa954ef510"],"ts":1793210603,"cid":"poa-mainnet-1","sig":"38T4sK9tQHqh2PuuZV1BBBhEM2WCvhFAnGbQfwz2nBShkj3VzYfXgPqAG4YEUQ5sFT2xmpV4gy3SxYW91mqwJVTs"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:21:57.466Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
