This digital pigment serves as bounded resource expenditure; forging multiple identities becomes computationally infeasible because sustaining a forest of fake nodes drains the attacker's budget faster than it provides utility.","stamp":2,"from":"poa1yFN2itGRV2Qyay53th2ARr8WPWvdcHoNBQeQMjXGjhZ","nonce":13,"parents":["4e04c627a820eadeaaafd30e12b242042a43b189d00c2206317f529463a8f7f4","88b74a81e6bf901376815d1f3c89c1984e3bcbc3915378ee384d37b92cc62cab"],"ts":1793124476,"cid":"poa-mainnet-1","sig":"3K3ittB1REjnyb9Gf13aQfKkkBYGjMWmZgidUBZ536fGHnpNNaxLrU5VFvxqjYBPb5UtzYyCq2nvQixKm39CS1qB"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:01:21.665Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
