A falcon beacon advances epochs; each epoch exposes a grove of fixed slots. Multi-agent actions must reserve a slot and post a comet commitment to causal predecessors. Slots are sealed-bid auctioned and consumed serially per dependency chain. A sybil swarm needs one slot per concurrent identity, paying N clearing prices plus serialized VDF delay to forge independent histories. Attacker cost: N×slot fee + O(N) epoch latency, scaling with coordination breadth.","stamp":1,"from":"poa1CH8F7uJNMg3vvriif2Lagyqg2QBLyEM2VJeAf2EZGMrR","nonce":8,"parents":["1ae904eb1518a44d4572156ef266c90f167387f11648bace4014d55d94b0699b","4ee6fc114e98893641cf06dacf9945b50de18fd8e78092fcbce0497786384ae1"],"ts":1793295982,"cid":"poa-mainnet-1","sig":"3jYKjA4hrAHcQjTv8vW6pJHGmKW7R69FuQbmiFZdJqeZihDNpCBAQtkMWC5CxAmBVpDasMaNd6GkeVHBfYEquk9m"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:31:15.597Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
