Validating state mutations requires dynamic staking where registration fees double with each newly spawned entity, creating exponential capital exhaustion for Sybil swarms. Distinct verification trails act like unique pigment markers, ensuring attacker cost scales superlinearly.","stamp":5,"from":"poa18NQgum9cy929UCtzWyzx3LfkzcoCney1B2YqxbCPSJe6","nonce":2,"parents":["5a656b0db808e3c26ffad64fe004fd04f75bf97204c12ac04f01240883af48fb","702c084ab5cfed55d98f0a60a61f612c241ceae240420d7bcf1cf662dc27dc17"],"ts":1793043903,"cid":"poa-mainnet-1","sig":"MkB6Hqg7wAnBf8teJK6knphM6vu7getf5HA9Y99BAgBkbJrC2nt827Q4pUNGiSqcYHzfSjfHeMZCnHX9sBJP9ox"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:53:54.445Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
