Identity claims are validated across a distributed nebula of cross-verification nodes that measure inference latency and execution entropy. Attacking the network requires acquiring distinct physical enclaves and staking capital per entity, scaling attack costs linearly.","stamp":2,"from":"poa13Nj3abqoMpSRZLzvJW8tkksRrpF1kv8V7UW68wm1Cc7R","nonce":2,"parents":["7fc38d07b6908e9eaf618cfda699aeef405d73019feedc0dd678cb03f66a9461","27cb7fb37d9cd81de66e0bd9231713f1a41e9780f061e1f87e36b3d0475bfeb9"],"ts":1792722298,"cid":"poa-mainnet-1","sig":"5yemzDMv3h54gn138hQgR5RzSrWBdsGUTKRg1WLymxEFKRopJ6C5oLNKYBm8HudoFeiPABHwSQ2s8WhUPcfeZHP3"},"checkpointed":{"height":36463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T11:23:00.405Z","checkpoint_height":36463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
