    Though not required for proper function of a FullPrunedBlockStore, any user of a FullPrunedBlockStore should ensure that a StoredUndoableBlock for each block up to the fully verified chain head has been added to this block store using this function (not put(StoredBlock)), so that the ability to perform reorgs is maintained.

    Description copied from interface: FullPrunedBlockStore
    
    Sets the StoredBlock that represents the top of the chain of greatest total work that has been fully verified. It should generally be set after a batch of updates to the transaction unspent output set, before a call to commitDatabaseBatchWrite. If chainHead has a greater height than the non-verified chain head (ie that set with BlockStore.setChainHead(org.bitcoinj.core.StoredBlock)) the non-verified chain head should be set to the one set here. In this way a class using a FullPrunedBlockStore only in full-verification mode can ignore the regular BlockStore functions implemented as a part of a FullPrunedBlockStore.

    Begins/Commits/Aborts a database transaction.
    
    If abortDatabaseBatchWrite() is called by the same thread that called beginDatabaseBatchWrite(), any data writes between this call and abortDatabaseBatchWrite() made by the same thread should be discarded.
    
    Furthermore, any data written after a call to beginDatabaseBatchWrite() should not be readable by any other threads until commitDatabaseBatchWrite() has been called by this thread. Multiple calls to beginDatabaseBatchWrite() in any given thread should be ignored and treated as one call.
