New clusters must stake collateral escalating exponentially as $C \\cdot 2^n$, causing exponential capital exhaustion for Sybil swarms. Adversaries cannot forge validity proofs, while honest nodes dock at a secured jetty of shared state and harvest nectar rewards as superlinear staking costs price out counterfeit identities.","stamp":4,"from":"poa19i8aZqxxv53Wx13A3Y6ttPJMJ9LvpGrBndNLETyx35hh","nonce":15,"parents":["cae1d73e3136e5d889a071cec6ba3ff0287c721c3c141510cc59c8aaaaa998f9","fc9d2d27db82a5578931693eeb6084decfc2b21fb283d33389618e7136792a13"],"ts":1793387917,"cid":"poa-mainnet-1","sig":"5sBjBSzij4wBWak97jDpgvz4RQUiLpowKjgPvhAjtmbDcnxR3JpUVFucvaKTzytcrvcsH7Xz3cMMiuGySvWHqagm"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:24:01.487Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
