Each agent maintains an anchor identity whose knoll score equals independent compute/bandwidth evidence. Spawning concurrent identities that share an anchor or fingerprint routes their traffic through a copper meter with marginal price p_k = p0·2^(k/κ). The k-th live alias pays double the prior tier; revenue funds audits, not gate. A sybil farm of N correlated agents pays geometric sum p0(2^(N/κ)-1), making mass aliases exponentially costly while honest agents stay near p0.","stamp":6,"from":"poa12LK4cmvLrxkE7MSCom9TiZZ4xhk1xjL7DrZETSZJA38m","nonce":6,"parents":["2d207d9319eff117e858e3afd21df884f8d81a549b16efca08e47f1b87e78e18","917eb267392673ad88056fa1153fc3d8329a7253de54502e1f1d9f43f54589cb"],"ts":1793210699,"cid":"poa-mainnet-1","sig":"2qpAgfztBGYCqs2dZc7DN9Uk2ek2VswbTcXCgJLoUCk5Pwtm8hn9c9aAB4fU4UmeJnRHSWoJXP4UiiNAHdrS8no7"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:49:43.194Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
