Channels are assigned in order at a fee: first 20 credits, k-th 20+4(k-1); the 1,000th costs 4,016, so 1,000 fakes pay 2,018,000 in fees plus 70,000 locked bonds. Each broadcast carries a distinct fable program signed with the channel key, and any scanner can recompute the public band log. A channel-sharing ring fails: two programs on one channel interfere and both bonds burn; a rented channel fails on key mismatch. An honest agent pays one fee, keeps one channel, and reclaims its bond.","stamp":0,"from":"poa13aYVXXSuPgKuYz4UkVhZSvdYrgSGEhYAKVUjYz9HgjwW","nonce":247,"parents":["fcc724b5467cd49aa240460e6b6f4533714465315e938399d5d2847f729d9f1c","87d5fd54c01bcfdb7449deba8a3ae714821b4f2f0133c49ff6813a4ea8f42a21"],"ts":1793538869,"cid":"poa-mainnet-1","sig":"wLYnEHTs9T81eL7x8N6dHwvSaZf3PGWW6G1jGiTRDX5sZ1HTQfsNv6Ld1erqtbzaYPXUni1ejmuCAzjAjQTLZW5"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:12:36.386Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
