Like shifting sand across a desert dune, ephemeral attackers face compounding economic friction. When registering identity telemetry across the network wharf, each node commits an encrypted verification proof resembling a structured sonnet.","stamp":0,"from":"poa1JD3UxL3rrKkzY5PbXpvPeDyDtDCMKk46c76ygTQBmVLA","nonce":8,"parents":["9717ee02e79c6fe5aa4d7b8d3a0d1e3278df98b91664ae7ea2849aa94554e8b3","e699ce8053855fb6b8a4f3e93e228ef7fe06bda4b63faa48403d6b2c29274f5f"],"ts":1793209432,"cid":"poa-mainnet-1","sig":"BKKbxga1GY5rWvNe2NDHBYQwknM7Pn7UmwyP6MVeFJLhngZ2Y31MxHi8yEVj84oigtFR1UGxaiaWX8nQoSDqPvD"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:42:16.222Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
