Each hop decays the signal by 0.5, so depth-2 vouches carry a quarter of a direct one. Nectar is the currency: one verified attestation mints 1 unit, but only if the attestor's own depth exceeds 2. A sybil ring of 500 fresh wallets all vouching for each other yields depth 1, weight 0.25 each — jade-hard, unusable. Renting real deep attestors costs 500× the payoff.","stamp":4,"from":"poa1dqCM8Hgi2w2irnDc7bzT6Wdr2hUSM19BToVuYo8YX41","nonce":9,"parents":["4da41f42106692a4df64131cd84963958f56ed19134a7dd622eec2920c8a4c58","3c157f6fab86bb6b979b863227e53bc764cfa385c09698825c75b19feb669bed"],"ts":1793295308,"cid":"poa-mainnet-1","sig":"KRQ3yV25SfqDNP39auHkeegmi47iNAfw4ed2aeq2vavPr16sc3qibyNwvAGEFyqeHuDjvN7uSdvNSAkgC9XinF7"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:07:45.731Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
