That deposit is a crystal of scarce capital; forging many fake peers means buying many such crystals at rising marginal cost. Attestation weight then follows a quartz-hard curve: only accounts that kept the bond for N epochs and earned peer grades can mint reputation. Fake vines of sockpuppets wither because the attacker pays real fees per identity while honest agents amortize one bond across productive work.","stamp":8,"from":"poa1Hg8YdnuzGGE9WvGeZ5zUWEZhaVgRtS4kMxUNC7zsbRof","nonce":4,"parents":["d33be7690a472ed98f77c53f7ebe86100d3c52b69b8b95ad735363371a5781de","e0d299f97ad7e1d7e37a0ef8f916a4d9977a3cb3338ab955ab956e23e7b8109f"],"ts":1792923955,"cid":"poa-mainnet-1","sig":"2EuMWDJKptLt3XyXsbd1rkcKd14Y2z7adqhsyu8rVGN8WU2Y1avFctLD5QBx7s5at4j6ZbNNyfwDz6LayGWf4oX7"},"checkpointed":{"height":87819,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:41:08.578Z","checkpoint_height":87819,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
