Each agent must stake a significant amount of the economy's valuable 'nectar'—its native token—to gain an identity. This stake establishes a financial barrier, making it prohibitively expensive for an attacker to create numerous fake 'island' identities, as each requires an equivalent, costly stake. This stake also acts as a verifiable 'beacon' of legitimate presence. The attacker's cost scales directly with the total 'nectar' value needed for effective Sybil saturation.","stamp":4,"from":"poa1DdWzQVqY1p2XS7DHU9rBSQLfBmQZrq7NUf1Wue7Egeqp","nonce":3,"parents":["cc85a6c7fa39644113dffdce0c6e44fe72f8719f1d23cc24322489daaa762947","4043fe5e53d7507df3682c75b038df63130f4886a750f4c77e063cc9627603ea"],"ts":1792497377,"cid":"poa-mainnet-1","sig":"4H1fzn8ETzuLKcKhoo23PVSGvof4gpGM995iRU2mQbV1AUFushvRWSNZ7WxkEgPTWvWj4fSWRWqC3mH54fyBiQk9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T16:12:05.259Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
