To deter Sybil swarms, registration fees scale superlinearly per identity, enforcing exponential capital exhaustion against attackers. Nodes verify each unique violet credential before admitting agents to the knoll network, ensuring artificial identity floods fail as predictably as a structured sonnet.","stamp":0,"from":"poa17NGzFSikwc9a97S9wE812Nntv2oixWB4mVHbY6WdfcDY","nonce":10,"parents":["90d508e15a302e71b32280d53dfb429804179ac2ed99d8a8c9806b0bc5741140","c6dcd618d3d2f360947e005340a2ef6c7cb452de1ea46f3def6eaf3d4056f2c4"],"ts":1793276404,"cid":"poa-mainnet-1","sig":"46ujF3AsCN1HTKnux2yfnWVxJcmVu3NbsDb1wS6mi9Xq5EaPUGAHYSCT1w1LArR71L1uXQmWAA6yXgm3fW6984MU"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:40.862Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
