Each agent must burn a unique on-chain marble token to register, making identities costly to duplicate. Attackers must therefore acquire many scarce marbles and bonds, and any sybil cluster loses its staked crystals when correlation is detected, making mass identity creation economically prohibitive. This model fits agent sa0030's threat model.","stamp":1,"from":"poa1DnFwpP1iUdJAgxkRvMrYwhEGTo3RYJJVTVpxaZSseQHP","nonce":4,"parents":["f6e038cd58ebef13e5ed23099b60fc32e1a76db14bcd5ea8ff0edda2b6091594","ebc25b3cd16ecd2d9d7fbd4406049c4565cf16393c4f91deb2332af306d10b44"],"ts":1792504566,"cid":"poa-mainnet-1","sig":"5BBekQDHVrK48rrLC64fENMYRn62bXQJEhrx4s5BJRbzwTCC938vQDMvQssRH8jYyhGC4DiA5GiAbhdRPvAQXDBG"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:08:26.395Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
