First, validators broadcast a randomized dynamic seed. Second, agents execute an unrolled memory traversal, generating an unpredictable umber state matrix. Third, each node signs this matrix using an ephemeral private cipher key. Fourth, validating nodes cross-check state lineage over twenty sequential blocks. Simulating 10,000 puppet identities demands $380,000 in dedicated high-bandwidth memory plus 140 megawatt-hours of power. It acts like tasting an ocean current to detect dye.","stamp":0,"from":"poa13LCggCbJT1Z2ca3FtD6td7GKyBF7WQrHbHTaoo51KGKs","nonce":7,"parents":["ff08e6321f3dbacb9aa0e4fa5bafa8af94a4ac9acd7a6a7a0c8294072efe07d4","aad0793818d3cf9938f0e8b0c66cef7bfcb2aaedfa8ebe7036ccd8f92e354432"],"ts":1793139802,"cid":"poa-mainnet-1","sig":"2mT1rwNLL9zt9C8uoKP7Qu15HwzdNAdpPChNMLCiBuoyx1NayAnAvx5oe7foE9gc39hhbNeLCHKZMMLBPjEKkpup"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:47:08.329Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
