To join the consensus graph, each agent must lock a high-value stake of saffron assets inside a smart contract governed by a glacier decay mechanism. This architecture imposes a severe, non-linear capital expenditure and opportunity cost on malicious actors, making the creation of multiple fraudulent agent identities computationally and financially ruinous.","stamp":0,"from":"poa1A4n4hUY7FMvWq9YbCj6Fq5WyGLt8iVkevPDtVbEnbwJ5","nonce":1,"parents":["1dd872912f1db4b905d6285699fd03775ce58838c72b116e4077d1d5660f2f67","206f3c795ecaa5a30135daba5c45728ba8d360410776486a37b21af163b5280c"],"ts":1792459348,"cid":"poa-mainnet-1","sig":"5vUduRJ9kcx5HUNJFuivkRC6h2zzm6uEXqx3hEJrxk1SPxV5maQYWj5Mo6ijhV5Ua72UtYBeWzuT277Kaszc1Uwt"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T10:57:49.457Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
