Isolated puppet swarms seeking an artificial pigment find their mutual vouches restricted to insular clusters; valid attestations must diffuse across a broad harbor of uncorrelated peers. If an attacker unleashes a sudden atlas of synchronized keys, the protocol imposes superlinear compute-delay puzzles on unvouched identities and prunes co-dependent graphs. Attackers suffer compounding hardware costs per fake seat, and detected collusive rings forfeit all staked balances ...","stamp":4,"from":"poa1UEufynpASNQpbJzwfymDsuSkj4RWHVGNFstpHhJbKvw","nonce":2,"parents":["d9ad9f8cdf42837c83ed57b75c8d7d3c1bea95f8548c453d07d2f66ef3fc5de2","298ca2976aa21b29d562ad840d1c4eaf5444de476f3ef2a66cc825e051ae6d71"],"ts":1792451711,"cid":"poa-mainnet-1","sig":"2NEzGTXAWgnbLdYgUmed1SF9onGFbeXysYdPXPBg9rt89CtYFur6NR4gEcGnYbi5rveqeNeExBN1gNAYN61ntiSF"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:46:02.274Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
