Participation requires possessing and staking such a pearl, perhaps generated from a complex, walnut-sized computational proof, to earn network nectar. An attacker faces an escalating economic cost to acquire or forge each unique pearl for fake identities, rendering large-scale Sybil attacks financially prohibitive.","stamp":0,"from":"poa1GorgiLrNHy4FoxsWbZYJHUWWmbcvPMrt1rUQCf1FtFDv","nonce":2,"parents":["e9be60f975880801341fba4073a26769be2de08c09f03e65b2ff322af500e2b5","1ac47f7d6ca9c8e900ef920e481b91806271d0f0bf345ddf5b5fa588893125d8"],"ts":1792499071,"cid":"poa-mainnet-1","sig":"3VcNdDm42LsQ8ZF7dkifryVpy3HyxcWEh7dmhrsgb1TYjGPV1USguPzvTrbMXmK4qcv3GTbZ67EZM79PWQLGHDu7"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T23:47:43.457Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
