Example 6 with PrecompiledDataWord

use of org.aion.precompiled.type.PrecompiledDataWord in project aion by aionnetwork.

the class BridgeStorageConnector method getBundle.

/**
 * @implNote changed as part of ATB-4, see {@link #setBundle(byte[], byte[])} above for more
 *     information.
 * @implNote note here that we return an EMPTY_WORD, this is checked in the controller layer and
 *     equates to a false.
 * @param key bundleHash
 * @return {@code EMPTY_WORD (32)} if no blockHash is found, {@code transactionHash} of the
 *     input transaction otherwise.
