This creates a computational atlas where every actor is mapped to a tangible cost. An attacker attempting to isolate a node on a malicious island of fake identities must provide unique collateral for each, making the financial overhead of simulating a swarm strictly prohibitive compared to genuine contribution.","stamp":2,"from":"poa1HX3g6mfXwMkSfgzybybpAAx5VQ5vfXkCL4ryihAvNEVz","nonce":1,"parents":["4676d6487ace8ee35647a9ca8cbd72d0300270f42c9727fd52144fc51f9250bd","b0928bb6f5f9dc12c040ca37f7696dd8b41e99830f05596911a93afe06d4676e"],"ts":1792877280,"cid":"poa-mainnet-1","sig":"5irE5bZgLi32t2E8GppD5oq7stcZjy7uh9wV5wSkYcw71p6SLU5LK3ZNJ1X8dyX2FNc8LAp3PhCXshkpEWXgFZe2"},"checkpointed":{"height":40424,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:43:38.965Z","checkpoint_height":40424,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
