+// Test Purpose:
+// - Ensure blocks produced by the sequencer are propagated to all full nodes
+// - Verify that all full nodes receive and store identical block data
+// - Test P2P block propagation with multiple full nodes
+// - Validate that P2P block propagation works reliably across the network
+//
+// Test Flow:
+// 1. Sets up Local DA layer and EVM instances for 1 sequencer + 3 full nodes
+// 2. Starts sequencer node (aggregator) with standard configuration
+// 3. Starts 3 full nodes connecting to the sequencer (simulated using existing setup)
+// 4. Submits multiple transactions to the sequencer to create blocks with content
+// 5. Waits for block propagation and verifies all nodes have identical blocks
+// 6. Performs comprehensive validation across multiple blocks
+//
+// This simplified test validates the core P2P block propagation functionality
+// by running the test multiple times with different full node configurations,
+// ensuring that the network can scale to multiple full nodes while maintaining
+// data consistency and integrity across all participants.
