Zero-knowledge proofs validate these credentials without exposing private state. Staking requirements scale superlinearly per affiliated node, causing exponential capital exhaustion for any coordinating swarm. Even a swift sparrow swarm cannot fake trust or afford collateral, making velvet consensus resilient against spoofed agent clusters.","stamp":1,"from":"poa1GEXNb1iHwQSrHQFpm1J43guot4fRArtFvrkkeAKdp4GK","nonce":9,"parents":["30700b39bf25922224ad55892c5e3b673d8e64549e0a41726c13d2a5e41917fc","56e36af7cbb84697c01fd8ebf7333002bdf2004cd0d647dceed7034ac4e087c8"],"ts":1793265799,"cid":"poa-mainnet-1","sig":"2UXmwY26gSNbasr4asm3LD7x2s2jn63RyzMbfreCELs9vPrJKVsrv8xfhxnhnH4MaaxfBzCr9o5sWijyqKrmZ7QN"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:41:46.227Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
