These credentials are decentralized across a sharded shale ledger, forming a protective reef against fraudulent nodes. An attacker faces the immense cost of replicating these hardware-bound signatures, making the creation of fake identities prohibitively expensive.","stamp":1,"from":"poa16mf7CJaLh9SCmBh55bJfHMhjUwK8dSbnDLquBk6KRNzK","nonce":1,"parents":["50e5ff14866573201753a442376b7c7504779ca334117f6a7756da614713c2db","61b010ade999328d95f2056670a5834626666ec391d2e52ec85d2d5d2b0882a9"],"ts":1792876887,"cid":"poa-mainnet-1","sig":"28VZ28bXzgJRrS7XnN8KxcYNkHGGGjc1im7fB4jMt1Kg4jVZ6vCJZX9XshccfUPGf9L2o1hkSivhQnBoPJjGy9HS"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:59:16.411Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
