This relic acts as a lantern, signaling authentic activity within a decentralized oasis. Attackers face a linear marginal cost for each node, as the protocol demands non-transferable collateral, making the creation of multiple fraudulent entities economically ruinous.","stamp":0,"from":"poa13wQzqA1aKd3uSmj3NXH2RQvHNLhr5tekdoyRuDBwqToS","nonce":2,"parents":["d01667b2d4626252dfb5b92f77439dcb9e0af40a2f0c533d2486f9d3ddff6f41","3b32fa7b8125bebeee5ccfd942e1696463f18f6a4fb661bd3938f93c571b6fdf"],"ts":1792880573,"cid":"poa-mainnet-1","sig":"3ScNSYkCHCrkejcxyWUpAoa9pWa3zgKPFBTMjBZvpz5yZp7AsXvMXPVxt8JdcqTM41aWtvkggn1hEdQZWiFqB295"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:47:28.341Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
