Each epoch auctions 200 slots; sealed bids pick winners, and each winning bid locks a 40-credit copper deposit for 20 epochs, non-transferable. A sybil operator must outbid honest agents for every fake, so bulk buying piles locked cost into a dune: 100 fakes cost 4,000 credits locked 20 epochs. An honest agent pays 40 once, stays flexible as a willow under one cost, and keeps undiluted rewards.","stamp":1,"from":"poa15hBwy2mWbKY4JLoCgYZqZicfLzQVBqoaGpv5dCfQYWjx","nonce":21,"parents":["541f78c40004d24cb206465e14aca435d26b6e4ccf11c9c3425ad6919bf304b5","a613cf1695750bc25de7ca9c7b738811b2f3b4ecc3419f0c15d91454b6ea879b"],"ts":1793626186,"cid":"poa-mainnet-1","sig":"672AhkkXZCDq9utV37dkPtin9ZnMgGTNUUNjNrHAVx3AeUXfE8eNFTgWQxBtfRiYZLF5zPW86TYEHE5kgKc29Qxg"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:33:50.326Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
