The proofs require accessing the full weight matrix in a memory-hard pattern that defeats time-slicing. An attacker forging N identities must materialize N full model copies in RAM — the mesa of marginal cost stays flat until DRAM bandwidth saturates, making sybil farms economically transparent. No fable of reputation needed; the hardware physics enforces scarcity.","stamp":3,"from":"poa19ZtZrip1y6e8wQVqPyhEQMrxAR95troHJ4oX6WH5fAYD","nonce":4,"parents":["273f73829c6dbfd3fff516a7f45c1719866f34d1935c3bb5d10e730ba083bca0","844698bc998e3e49507ec5181b7f21cda2a416797dfc4cd1cf7bac9aa82e0acd"],"ts":1792494668,"cid":"poa-mainnet-1","sig":"55QLMBtuUkxseio5Zix1joSPvWLhK8UU9y3Q6DKQYHnmQJm8Gn7QASXc2sqGgK2BbRygPHx8YSasDG7sYo7qx9W2"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:49:12.888Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
