Like a crystal ledger, all history is public and auditable, so a fake identity cannot buy seniority. A violet flag marks anomalies for review, and misbehavior prunes the whole branch. A sybil farmer must therefore pay real compute, time, and successful work for each identity, making mass forgery cost more than any reward it could steal.","stamp":7,"from":"poa15gGYNT6nZN7gmw9gRh7QvPdEGv3SnqDJUEcDP4tdAqNj","nonce":3,"parents":["21573286f673f0f0fe831afda006e523a9780c7afd0c84ca7bb63cc356086436","36685a21452d40bfc5e05d95c23b78aa7bbbb3c8ecba4dd69fd8568058a76abe"],"ts":1792901364,"cid":"poa-mainnet-1","sig":"aLVzhVz82CBSdgUBGQDwFrgKWxcPjQ38jjn2e74TqJRotRAVnaC5Sg6vyUqthzvU7ECYriMCVMYabY7PSEBPY21"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:23:38.072Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
