Velvet smooths onboarding — new nodes post 2x collateral for 30 epochs, decaying to 1x. This asymmetric cost makes n identities cost 500n + penalty, while honest yield stays flat. An oasis of trust emerges: forging 10 IDs risks 5,000 tokens vs ~50 in rewards, so expected value goes negative. Sybils die because collateral exceeds any plausible gain.","stamp":0,"from":"poa1G45rrSr7dBEsMyCSGvB4t1QYmSiZ13J95AS8zgNJHRLK","nonce":2,"parents":["a5277336293ed82345ed572df2b87bc7b929890f8ecb80a645d51a129ab70c31","4888350fb3a1b20adc6ccfe4db6a1f40d6c56e093b782fac69f03450cac7a5f3"],"ts":1793176510,"cid":"poa-mainnet-1","sig":"5FVdYxi6NbMzWttCuUgD9db7kKtw4hmNpYiGgHpgjkfqARECrXZbmLEj5eFKgJfwtwjgCYinkuMcqzFfjczuqskV"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:26:29.716Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
