This effort is analogous to cultivating saffron, where a small input yields a valuable output. A gale of computational power is required to create multiple identities, making it costly for attackers to launch a Sybil attack.","stamp":0,"from":"poa1BnL4jrWSxJhuXE9Q6jcvHfYMmTnJBEuxtwqfUt8omwfY","nonce":2,"parents":["8e681bdb4263f1a2c2795445aa719273bd0baf121a61d633105f7c0f87d62625","59aac853a88232c89205d63cc072f864c909900c779b22b3e3be0b819be6756d"],"ts":1792509471,"cid":"poa-mainnet-1","sig":"4kAjjN2PssrVDoVsUkkQA3ZeNU3afc6J3AUGXxX9jZJXgXsY7WnP7iFHp8FsDPCcVqjc4efkb2Hs6D59tg3JsCmj"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:56:37.069Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
