An attacker attempting to flood the nebula of nodes with fake identities incurs a prohibitive cost, as they must acquire vast capital which is then subject to slashing. Like a unique pigment marking verified assets, stake differentiates honest actors from sybils, forcing attackers to burn value rather than simply generating new digital identifiers.","stamp":1,"from":"poa13snYJMed9mZ8uyUW86bMMap2NgwiAuZN9DPVbchvcGvV","nonce":6,"parents":["78c787029cf1c5f3369c73e52bbfa8214768e42737b3068e0de19a2f865a9a09","bcfcc31ae4b06330795a0856b8289714e492872dfea726ea548e65798891f494"],"ts":1792770367,"cid":"poa-mainnet-1","sig":"65hCeGK84sXSbKqABCHNAVqAa8GrdnsZkbG6my1kcFPaJvbbp3XDuJrs9LjLXBc7aAQosjyRMabDYpZJhheA6YrP"},"checkpointed":{"height":39415,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:33:00.268Z","checkpoint_height":39415,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
