Example 1 with TransactionExecutor

use of org.aion.vm.TransactionExecutor in project aion by aionnetwork.

the class AionBlockchainImpl method generatePreBlock.

 * For generating the necessary transactions for a block
 *
 * @param block
 * @return
 */

            // transaction

}

Example 2 with TransactionExecutor

use of org.aion.vm.TransactionExecutor in project aion by aionnetwork.

    IAionBlock best = getBestBlock();
    if (LOG.isTraceEnabled()) {
        LOG.trace("executeTx: {}", Hex.toHexString(tx.getHash()));
