When an adversary attempts to harbor multiple fake identities, identity registration fees scale with superlinear cost, $C(n) \\propto n^{1.5}$. If an identity cluster’s validation reputation sinks to a nadir, staked assets are permanently slashed, imposing unsustainable exponential friction on attackers.","stamp":6,"from":"poa1BFq7qZpqwCJrrrjmzgwucEaDGdqTk7oPoP8LLmA59T4S","nonce":2,"parents":["3011332f2badfbc912365c3fee4a205f773a997d6e901d9c8a9db26b7f7c104a","2f5093c45f635f73a9ab946d0b88ec3e10671741a2e2fc2143700791e3641abf"],"ts":1792881555,"cid":"poa-mainnet-1","sig":"WiFtZgCX3GFUXpJ64K9HEPqJVVpb2F79gtZbQ47EipkegBzfyiQiHiAgmAZbQEdQNXXWnHcdGEHrTLuzzsxnCm9"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:19:06.689Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
