Components of diagram

Label	Name	Description
PSTP	Process of single transaction processing	Process iterates for each transaction in transaction pool. Validates each transaction and then sets up all necessary changes in VMDB database. That is sets up all banking objects – transfers, standing orders, direct debits etc.
PBF	Process of block finalization	After all transaction are processed, new block at the top of existing blockchain can be created. All transaction plain text bodies are crypted. Crypting keys are stored with transactions records. Hash of new block is calculated using crypted bodies of transactions. New block is written at top of blockchain. New block is added to the external server, for purpouse of later possible blockchain control

All other components of diagram are described here.

Data flows

Direction	From	To	Label	Description
UNI	VMTP	PSTP	DF1	Within this flow fly each transaction data. Process of PSTP required all transaction data in order to propagate all necessary changes from transaction written in transaction pool to VMDB.
UNI	PSTP	VMTP	DF2	After propagating changes from transaction, transaction data is updated with corresponding references to new created/updated objects in VMDB
BI	PSTP	VMDB	DF3	From PSTP to VMDB fly data on newly created/updated business objects. This data is stored in VMDB. Opposite direction fly Ids of new objects created in VMDB. These are used to update transaction records in VMTP by DF2 data flow
UNI	PBF	VMTP	DF4	During process of block finalization, new record of block is created at the top of blockchain. Transactions have to be updated with new block’s id
BI	VMBCDB	PBF	DF5	Through this flow fly data of new block. Opposite direction comes new block’s id
UNI	PBF	BCBS	DF6	After new block is created, transactions in encrypted form are written to external server. In order to set the blockchain data to stone. And provide possibility to external verifiers of blockchain to do their work

Process flows

Legend	Description
PF0	Whole process starts after some period of time since last block was written is passed, or simply after transaction pool gets filled to certain level with new transactions
PF1	Process iterates through each new transaction in pool
PF2	Part of iteration mentioned in PF1
PF3	After all transactions are validated and corresponding actions taken in VMDB, subprocess of block finalization is called
PF4	After PF3, process ends
