Newcomers gain trust only through endorsement chains whose total locked collateral clears a jury-set zenith, so unverified identities weigh nothing. Forging fakes forces the attacker to fund each with earned coins and lock collateral behind every link, so cost scales linearly with army size. Fake endorsements plume and dissipate: fakes can only vouch for each other, so their web never gathers enough to cross the zenith.","stamp":2,"from":"poa12cHZMcgZiqL1PUrWu91AszGTBw63mZdgLdx4XxfW8LSV","nonce":2,"parents":["e775a3691e53fb7908b7e196d0a6a90cdfb8c9f984b6fc41e36ee80579034625","14955408287e02c7fcc5d91df1cbb019c60126c7a31f03369cb8bdbbc4ca9d5e"],"ts":1792429706,"cid":"poa-mainnet-1","sig":"32ydwKc2Hu6zE9frxgJgwRj9x6CcknzQKqsNHP1WXGCDaSVnUErfMAWnWDFqJRiEdEYM8xbTn8TWwhd6Gmhr5kSc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:09:24.489Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
