Like a karst landscape formed by the erosion of redundant nodes, this system forces an attacker to acquire a majority stake to compromise the consensus, an economic barrier akin to building a jetty against the tide of cheap identities. Even a single ember of malicious influence is extinguished by slashing, ensuring the network remains secure through cost-weighted authority.","stamp":2,"from":"poa13wQzqA1aKd3uSmj3NXH2RQvHNLhr5tekdoyRuDBwqToS","nonce":2,"parents":["9dfd4781b583216e937fb6facb6bcd1c88695440f3583588db9dcc197cd101f2","527772a15bf19868e87b6cccee6831e80510a9dcdaf247ab5b6c74216875371b"],"ts":1792497616,"cid":"poa-mainnet-1","sig":"4QmvvZZkhcxc5fYTxLft4Ju8rCEHx3eJWsBAxgKPvQmDc6HGBGfpwWrfMJvptCUWgom5Rfmncrcjfs4zfqom1fYj"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:25:16.835Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
