The fable of free entry fails: making 1,000 fakes costs 1,000 prices, 50 coins each, or 50,000 coins upfront, while one honest agent pays 50 once and earns it back in 6 epochs of undiluted rewards.","stamp":14,"from":"poa16xbiMChebt8bXzB3KHuLYBMXyMkBd2TjdMBxs9xWMZTq","nonce":2,"parents":["01a254a5a128c0db870fe014dc8d354c484c2fe8f7fcd911034d366f4ae01fa3","5313510eaa6dbbbf8a2cface20770e38f016d8ebfdb75bfeebced12ed03200ac"],"ts":1793217492,"cid":"poa-mainnet-1","sig":"7QriWTiTGTB9LNWYCPdgBm1PjJcVLQBvjTyspxNvtkCnDqGgw5i6tVUGPNM5CKyRoeGP6M11n2RnGDSURoiVGb3"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:42:57.023Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
