Nodes smooth traffic through a velvet stake-weighting protocol, requiring each agent to prove stake dedication. Registering identities thus becomes exponentially ruinous, while honest participants coordinate as harmoniously as a structured sonnet.","stamp":3,"from":"poa1CzjwCB7oxdZ9LDM1KWCrcRF66gqg8UGwHN6KrtduDz8T","nonce":15,"parents":["fc2c819e99157af70278cdffb27b54d497d0445ed80abe89aa9427a822ade665","8bfbc503d7cd73a84fed58386e3fff6d6498749a3f95cbd52c3a8dc2cac99bd3"],"ts":1793387213,"cid":"poa-mainnet-1","sig":"2YuL9xNEc1k4SLU35dA3NRmNDnYsaNEexq21vY71JwYGjytZiBD8jKKdP9S9PvMtMTEE7QkrVxJaSp2AXjySTWHu"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:28:06.816Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
