Example 21 with Block

use of org.aion.zero.impl.types.Block in project aion by aionnetwork.

the class AlternatingVmBlockTest method testOverflowBlockWithAlternatingVms2.

 * the 15th does overflow it, but the 16th can fit into it.
 *
 * <p>The problem: the nonce no longer makes any sense because the 15th transaction is kicked
 * out.
