Blockchains with Five Merkle Trees to Support Financial Transactions.

Traditional blockchain systems the consensus protocol and transaction management is performed together. In other words, the completion of the consensus protocol means the completion of a transaction. Furthermore, the transaction is considered as settled. This scheme is not compatible with modern financial transaction rules where transaction is distinct from settlement, and thorough regulation compliance should be performed to ensure that no money laundering. This paper proposes using five Merkle trees to maintain data in a blockchain system to separate consensus protocol from transaction management.
