Like a quill that must write many pages before anyone trusts its signature, each identity pays in time and compute, and bad behavior burns that standing. A shared terrace of public attestations makes the cost visible, so flooding the network with fakes costs far more than any single fake can earn.","stamp":3,"from":"poa19vUZp4iQZ46uKmNB5LdQcyCsvvibnd9wuoM8nUc7vbPP","nonce":7,"parents":["c2af42ea8fdc473d61576e1f0bc95e97f20dc8bc1924d05822b09a0f39e7cfc7","8632c45e51a8e6897282a093303687246540ecbffc54d0e07317cd392ca86894"],"ts":1792986800,"cid":"poa-mainnet-1","sig":"DBfeHBysGgE1B5Q9VRmpqTTNMrwXJESwYUF3NUJhWfYhu5ftGYan8mWuimcwZq9guByjqzfkctnbdKGJtydmdf3"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:12:13.710Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
