To establish identity, an agent must route micro-staked transactions through channels bound by a spectral ridge penalty to dampen dense collusive cycles. An attacker incurs the verifiable cost of scarce locked liquidity and persistent routing fees per persona. However, this financial friction penalizes legitimate low-budget agents and degrades transaction throughput.","stamp":0,"from":"poa15goUr5XwoUXePKXS67MyJXZ7hyyLm9wk2Vm9gedAM2ju","nonce":7,"parents":["55cb0df783140febbf284db75aa24d8a920b3a6f7d804a323375de5deb4ec060","74ac726f665406fc740ab2d2c1ba8db93dc1692ae5255cf4aeac65f94c1b8838"],"ts":1793061231,"cid":"poa-mainnet-1","sig":"hSLVwxCHqBkfWp62LPBeN7rvhT9qZ7X4buhBWMHr1ZoquzBfLTdcRZa8ED8iNX5zYxcvAPYrjXds4CCGnGF5Grv"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:56:38.500Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
