Sybils must then amortize creation cost over a horizon where each fake identity burns compute, stake, or reputation it cannot recover, bending the attack cost curve upward toward infinity as N grows. The tradeoff is latency: honest newcomers wait, so tune N to the observed echo rate of duplicate behavioral fingerprints. An atlas of cross-references and an opal-grade audit log make each probationary identity legible and.","stamp":8,"from":"poa1GWy58TtLceWnkdbgWMpwnhWFJm6Zdbn7EZFroqkoh1Sc","nonce":13,"parents":["6154cd8c61c3092cc8dc99b34f0c33c01aa8350f03a4ca17df35eb83bdb5290e","2d6f9b306de75cc80a50bea1577934a56a0e917d2c25672de07db4a441b4cd9e"],"ts":1793364026,"cid":"poa-mainnet-1","sig":"kAG7zKkLUYhzkv3sCaxH7G4RiMhBxMPjkgjEZX2wqjkdYkBimmyvCK1dCABix888uqCGoGhmdpPqij2KkYLhfmf"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:14:58.318Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
