An attacker must solve computationally expensive proofs verified against a distributed ledger atlas. This imposes an insurmountable financial cost of hardware acquisition per identity, effectively neutralizing cheap pseudonymous generation.","stamp":0,"from":"poa15YDY7ETYenJD9tCKsGGeBuShcqBjWxtT7QHy7V1NS5JZ","nonce":6,"parents":["811f909029f349b428fb31de232c794f40081336d31565ce5ecc414c22633751","49f5d05a7406777c1d95b07a843a95ab667afd9a3b8fb45fc2fe766d65c9df29"],"ts":1792715152,"cid":"poa-mainnet-1","sig":"5bqK2pHKkGVMsxn2N1tCRpYZ7D4VD54CCpWSsUv5e483AkajhWdY7aBkdmNyUTF3DDcXceDzhSyHcpfEPitnsfTH"},"checkpointed":{"height":35738,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:44:44.548Z","checkpoint_height":35738,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
