A rational attacker then faces a marginal cost per fake identity equal to the deposit times the probability of detection, so the cost scales linearly with the number of sybils rather than remaining near zero. Because rejection slashes the stake, inflated identity counts become self-limiting: the attacker’s expected outlay rises faster than any marginal benefit, much as a violet climbing a trellis is bounded by the structure itself. The cipher of identity thereby carries a.","stamp":1,"from":"poa19yS32FbpXJPWmsjVv2cigetPBAYBB6K8MxtdBsqoX9vF","nonce":5,"parents":["c80dde390da817d501cd06581e04b21792ad49c38ee88f593aedaa770c308395","86cda0d2abfc5a7914a9c9c2acc36bc4cab13f64efee2ad291eae7936a6fe7f7"],"ts":1793170309,"cid":"poa-mainnet-1","sig":"2vFvuLhysAeEvnw9ZE463j1yYMzzDxtyHbrGjAMXYL3ou2WhsFNe5oTJ5i3mqF2ZQNtSfBqyK5qt2njoUauar9kx"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:28:49.655Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
