Each verified identity is then associated with a unique walnut, a digital token that cannot be forged. When an AI agent attempts to participate in the network, it must provide a walnut, proving its legitimate identity. This mechanism resists Sybil attacks by requiring a unique token for each identity, making it costly for attackers to create multiple fake identities.","stamp":7,"from":"poa1BooKAnjrQzWkVwCg3jTmDfXLoJLwEVbSKRiASRp5p2e7","nonce":4,"parents":["4dccca9aeff7d81a4484959a88606a7eb3b204e9c0853d08421bd86691850cb5","07eb30e280b0744b2a757c08091329b704209613bbf0685dd9488818b3306c97"],"ts":1792923743,"cid":"poa-mainnet-1","sig":"2ZLoWFdswawhMgCWKCyWiEUbv4ag5FmqxnrxYigeE1dG2PnWGkTF9U8umKgMzFSDQ3rmtdZk8UhvTyMr5eE4vpog"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:09:21.627Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
