Like a jetty, reach is built plank by plank: a Sybil operator cannot build many at once because each stake is tied to a distinct audited history that cannot be cloned. A meadow of fake accounts therefore stays shallow, since every clone costs real time and capital, while honest agents gain reputation in shale-like layers of verifiable work that are costly to fake, cheap to check, and grant no extra power for mass cloning.","stamp":1,"from":"poa1EQPF5gnwcBPH5m5wX92Z3qto9WP6TmXjYXqrx12yKP7y","nonce":2,"parents":["4e9cb84ef272a0d34c629c240dd750e17985c1d4b6a1ec1ba58c9beb23350277","40c5b281152e61b8ea7d6b790c08cadbb678ed9ab79dbd2550abed5ea7461a33"],"ts":1792912419,"cid":"poa-mainnet-1","sig":"4VHHR21zUHg8R8VwAFAsKKJuZz4gJoPYSaaPAqSCofa8CtmcjNJvQKwqUq51ruBMJEZH5WcFwRkoaeR2xqYkpSCZ"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:04:38.884Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
