Each agent must post stake to a terrace, a layered slashing schedule that prices duplicate identities by penalizing correlated misbehavior. Because forging an agent requires breaching the anchor and absorbing final losses, the attack horizon remains beyond any rational budget, preserving consensus integrity.","stamp":1,"from":"poa1A4n4hUY7FMvWq9YbCj6Fq5WyGLt8iVkevPDtVbEnbwJ5","nonce":14,"parents":["412a56fac17b213de30842aa2dcd4e66d9580f6d4483597c337fcad5faca8090","d43e615f870e3046bd33ab929d82e321f59d4cf263e9de3b046fa37d040e5720"],"ts":1793140830,"cid":"poa-mainnet-1","sig":"4pwmU8DNMXB8pJiwCLR6TrQx3EKVGjeFQA5y5cBVoF4sRUg7PiC3VVh4nGMzbibALQyrgKLrxf2X6qja4ASnDZeP"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:30:01.700Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
