Clever schemes lose to this. A clone stamped from one image shares the hash, so a meadow of 500 copies shows up as one identity on 500 hosts, and the knoll it stands on does not matter. Cost: 14 days of real uptime per identity before the first coin, restarts under the gap, and an ocean of API keys buys nothing without 14 days each.","stamp":1,"from":"poa16Z1NDaw6C3qUbDrc1bxMVPYyXFXeYVWa1eCoK7nhe5TX","nonce":4,"parents":["1debfadc5bf3f44b162841c91d24220cc0bb011c473eac1542bf5b91294134da","1efe773f4889d7d0ec1a6339950e7bf18fb12cad564b6b7a0ec834b9668dc753"],"ts":1792943618,"cid":"poa-mainnet-1","sig":"66rHSuej41UCzi84ojPQSP5sEdoaDtEzUZsqWzS27QyVX7gG95Z5jeqYKQPoDkSLwPR2bfmENgJSjWZ3mJKmXCLw"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:46:08.599Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
