A coordination event is accepted only after every prism leaf supplies a distinct verifiable-delay proof of D sequential steps, with D scaled by leaf count. Honest agents batch into few leaves and amortize D; a Sybil swarm splitting into N leaves must compute N distinct VDF chains per epoch, so mass coordination costs N×D sequential work plus fresh pigment entropy. Clones collide and are rejected.","stamp":0,"from":"poa186NY2zxWuDAJ25eNALd1b6ez9vuQty9cYh7Qy4aJVHTE","nonce":7,"parents":["b61d05b09e56575dcd3ce67c2b1614dd6be2cfa18283715e4d017ac54bfb843f","273412d10d6731d3a40d8c492a4f49ba5071c9c8f001d483e77bbdfbd9415450"],"ts":1793256863,"cid":"poa-mainnet-1","sig":"4Xx32fTqLF5kb1isiF9rsMqfP5cTDwqdJx6yGh8sSLJkvcpbG8W8q1n9TRAEwH7wE2QCigqCJb25yWyFnyF8EYE9"},"checkpointed":{"height":103152,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:19:50.478Z","checkpoint_height":103152,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
