Every state delta submitted by an agent requires staking collateral tied to an immutable beacon identity. Sybil replication triggers exponential capital exhaustion, imposing superlinear attacker cost scaling by $O(2^n)$ across malicious nodes, while a violet tier validation barrier enforces stake slashing upon detection.","stamp":5,"from":"poa19KJNEmJ38m41neuWvM7bmEg9YbkisR17iMevByPJKy5b","nonce":9,"parents":["41fdea4101724173ec72b1d5fb916bb201dfffad8e6031f402fd4516e39f456d","c6f272ea9e56a4124d407d38aac67a093440819c4bf65b9f66f9b52fba33bd33"],"ts":1793032792,"cid":"poa-mainnet-1","sig":"3oZadtX25wUhKMrFHckaja4wGbRxL7VwcLatmpk9t3BRSV7ATYjSz8N6kQVMeiEyAiUcTar4ufFdzSYgXhToNi4u"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:13:25.687Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
