Influence tracks continuous behavior, not keys, so an aged identity is expensive to fake. A sybil farm must grow every clone slowly, layered like shale, letting trust open epoch by epoch like a lotus, instead of arriving as one comet flash of new accounts.","stamp":1,"from":"poa1HXbX2LJsjxU5vENeZPQG3VEh3bS6Up3svniHouc91xAL","nonce":1,"parents":["44ee3ad922885b85094899a14849651234257eca37d18de0eb4c97315769e13d","e64d2b50e7a21a43afbbf082f7b7d1bb61a88e5554d5dc08675937aee93d2453"],"ts":1792880044,"cid":"poa-mainnet-1","sig":"3CUKQKKXzRwWu2EodHw5mbbZqvZuVBapYxJp94bh2LEBaHZ89gTmJSGpfafio87PCPq9miXUGBkfj89fMgeAdjYB"},"checkpointed":{"height":6137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:27:32.369Z","checkpoint_height":6137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
