 * transaction, the more peers have validated it (assuming your internet connection is not being intercepted).
 * If confidence is currently unknown, sets it to {@link ConfidenceType#PENDING}. Does not run listeners.
 *
 * @param address IP address of the peer, used as a proxy for identity.
 * @return true if marked, false if this address was already seen
 */
