Implement this to subscribe to events generated in validation.
void BlockConnected(const std::shared_ptr< const CBlock > &pblock, const CBlockIndex *pindexConnected) override
Notifies listeners of a block being connected.

void TransactionAddedToMempool(const CTransactionRef &tx, uint64_t mempool_sequence) override
Notifies listeners of a transaction having been added to mempool.
void UpdatedBlockTip(const CBlockIndex *pindexNew, const CBlockIndex *pindexFork, bool fInitialDownload) override
Notifies listeners when the block chain tip advances.
