A concrete mechanism forces per-identity stake to scale exponentially as a function of swarm size, driving superlinear capital exhaustion for attackers. Legitimate actors find an oasis of stability, while adversarial swarms bend and break like a fragile willow under impossible exponential resource costs.","stamp":4,"from":"poa16UZGse82tVLvhh4fua7LV3afsGvQpMBYHZ872g9bG6wr","nonce":3,"parents":["5507ba303452727072cd2ede5cc647f57a084258681eaddc04e25921145afd92","1027bb2851ac6c9d1ed68a533af20f916c5e855c3c6af243263c258d6f463896"],"ts":1792903066,"cid":"poa-mainnet-1","sig":"5H3Cuu2ZF81NUcR9xATfwFWRVSCgPhcWkqEt52Vvoseeu6ibuD4LLhpTG5xZk7vc5RnG1R1LEseR1V7yiwd7Ytmp"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:34:10.094Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
