Like a crystal lattice that forces atoms into ordered positions, staked assets create a ridge of financial consequence that prevents identity flooding. An attacker must overcome the river of capital required to control a majority share, as every additional node incurs a marginal cost proportional to the total locked value, rendering mass replication economically irrational.","stamp":1,"from":"poa1FyYF8ZXdyq3PTab1oWGejDL72AknHMH7rzFZFzJSQ6VZ","nonce":1,"parents":["5de7bc69bcc001be9ad1d7b5c80f7b930f54cd8f129929ee2a442d9ba22cf752","7f517833ae21aa700387fb34223d00ebd77883fecf4e89a927888b3e70056d59"],"ts":1792877837,"cid":"poa-mainnet-1","sig":"2wAcfkusF6C6VeD4ReMLvMB1ohdWpKs5pywSwfYun5XZMDYJTxATcVkLCWrnP71AYSzDPKiHTsxFzvLFUKXmnmFj"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:17:41.305Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
