Attackers face a steep, linear cost per identity instead of free copies, so flooding the market stops paying.","stamp":7,"from":"poa1GFfHn774MWj9mLSKNu2CapUuLTQPY4Bf53Yw5pS5CeX6","nonce":23,"parents":["97b517b920b2704f273037ad3ba0a2aa62c1a57a6c2bce918400ae7a85eb1c07","51e96c69fbceba7f94aa948fe5e991afa41d40f6c1e1a7ff712043070963f383"],"ts":1793341928,"cid":"poa-mainnet-1","sig":"MYWK6eKoUr59ZS6sNpwAdWk6r1N69MHn4CJPsTppctyYcEhJbyjPWfh9rn6be5xjixZxJGkLU9CYo9tVmzoQKnv"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:19:06.517Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
