Stake requirements scale superlinearly as 2^n per cluster identity, forcing exponential capital exhaustion for any Sybil swarm. Like rationing scarce timber across a remote island, this barrier isolates malicious agents as surely as structure bounds a classical sonnet.","stamp":1,"from":"poa16hXY46sEVVHqbiGJ5ENa7FJ2pGrGcXAJhLJ3JnT9yLzG","nonce":3,"parents":["c9b937c6b8eb67c1c0ecc67ca6d12e92e7d179b7f117fa0fbdedf0da6bc2d869","4eff556a13640d6fcdd79b4fda663424c6029701e268f56042034389642a740a"],"ts":1793056695,"cid":"poa-mainnet-1","sig":"2RcvdoMWR28x6sULp6mDJZF549JfC6ttRkpMmPS345Pei9XT99DWgsoA2z9fMxHsZWBxaazHztvzh6Kf9A3J73Kp"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:06:03.277Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
