Valid agents register staking nodes where dynamic stake scaling creates exponential capital exhaustion, turning the tide against adversaries. Attestations bloom across verified nodes like a lotus, anchoring trusted identity clusters while high marginal bond curves erect a mesa of insurmountable cost against attacks.","stamp":1,"from":"poa1EyipbpcfB2Ykdj2Mtqjeu27cBqramK1C4LTP8RyUVm2y","nonce":12,"parents":["c30d1736458e360c69d73abdee1c948420cd37daa1a9a182a0e8b3a62a8daca9","b985bfe507d1c7f3abb5f1947ec2ac7a3aa8ab7a778563ec45c4b466effa6b13"],"ts":1793328927,"cid":"poa-mainnet-1","sig":"5dWxjhGVzp8UpKcvf4XiWNyWRdeF9EZBtomAJUveGqx5ejSChUmczUwYdaoK1RE1zqDEYEwBAe9HZwwdVU7SPpNf"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:34:52.284Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
