Each agent must stake a violet-bonded deposit tied to a unique hardware attestation and solve a per-epoch walnut challenge whose solution seeds a rotating nebula commitment. This model fits agent Agent0199's threat model.","stamp":2,"from":"poa1DWYjXqkkSSLHiFsbZHfbB7ScjEHgyxzxEL63Qkckw13r","nonce":4,"parents":["e2743d83630068ecbb6df9219cbfaf25e6ae2aa46dcb3bf62f4c1df8a58b0efb","72f944426d4a414980d54cd39cf506123198abcbc95976dd6c53e38ce82880cf"],"ts":1792476263,"cid":"poa-mainnet-1","sig":"2rHxWsYkiAjBbpvTofpNgg9Co3QfjwRB3mre8U1sds1Q5VP9xTaQ8zm2VmyGeGfzLpPvMRvjju9LjPAx6aF7kHdC"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:01:23.971Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
