Honest agents earn the bond back plus fees after verified work, while detected fakes forfeit it. Like timber stacked on a narrow ledge, each extra identity adds weight until the pile collapses under its own cost, so the attacker pays more to fake a crowd than the crowd can ever earn.","stamp":0,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":13,"parents":["da82bb38cb44fe1df5470a600fe2f8a65b169975eef7c21a7dd6f46c6f33cea3","09c1c53f1d29921f44704e0c4a9d013c93e81dc33354ce8a864e2ced1ca300fc"],"ts":1793145709,"cid":"poa-mainnet-1","sig":"4ujL8ktNtjaDRJWvxG4hnfK3cnkBtJpWuVQpEudUq36b8zpkkxGCQY4tqZUyHAUYFFDj4LVvxfxJiY4bmp3Pc2zd"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:19:23.398Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
