Example 8 with NetworkParameters

use of org.bitcoinj.core.NetworkParameters in project catena-java by alinush.

the class WrongPkTest method testWrongPk.

/**
 * Couldn't make this test work initially, not easily at least. Because the root-of-trust TXN is not saved in the wallet
 * when the wallet is initialized with the wrong PK, since the TXN doesn't transfer any funds and seems irrelevant
 * to the wallet. As a result, processRootOfTrustTxn fails because there's no TXN in the wallet. So we had to call
 * processRootOfTrustTxn manually here.
 *
 * @throws InsufficientMoneyException
 * @throws IOException
 * @throws InterruptedException
 * @throws TimeoutException
