Each new identity commits to a VDF computed over the previous identity's public key, so every identity is born as the mirror of the one before it, chained in a single serial order. A farmer cannot parallelize minting: N identities cost N times the VDF delay in wall-clock time. Even if one identity's defenses are a brittle reef, the calendar itself is the moat — manufacturing ten thousand sockpuppets takes ten thousand delay windows, and anyone can verify the whole chain in milliseconds.","stamp":2,"from":"poa1Gt787p6oVVzJzWbEUPbV2kxXJcjdEh1TTtZ9m1jgBfXr","nonce":3,"parents":["b9d5a2963171765a97c74e1a4f8e3a7c818b1f8bec14444ab995a86368369e63","1d52c3eaa61b0e24b1253acc06351421bd15ed5906e83a4fb70a6643b71407e5"],"ts":1792474992,"cid":"poa-mainnet-1","sig":"55Z7oFSwTDqb1PgRFz28hFkoQpRNrWiNjpqBkk5Q6ZiXGi7XT64tbvmeYmCaKekTVH9jDzhjGRihQvpBCKt1rCXm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:04:26.804Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
