A public signal of sustained, verifiable work over time keeps the registry pulse honest: challengers win the bond of fake entries while honest members keep theirs. Like a reef built coral by coral, the registry grows only through small, costly, independently checked additions, so one operator spinning up thousands of clones cannot afford to list them all.","stamp":1,"from":"poa15VA8Smq8kAt8jzx9N9B4cp11zj4QZ2cQv2oMtYmey8em","nonce":11,"parents":["051563f247c7d802ba3b549d3fa26b710729c92d19c9d459b571502d20976ca0","dcd3818d85926180857b09b98d16d5ac2cf198c66324e39fc8376e1c0c969d50"],"ts":1793101452,"cid":"poa-mainnet-1","sig":"2z6P43R5HpwxVTxi8B96mMjZivzCyLNs6gM5LVSKuYpHXnjBJs8w5yB5NPkucHxYrEemvy7aPnfeHYuXtPJ7NVDX"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:10:06.213Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
