c) executing transactions incoming from SEPA
d) quequing all transactions which cannot be sent to SEPA beacuse of limited availibility of BoL services
e) tracing transaction status (according to statuses specific to SEPA), holding account history for each account
f) holding account balances
g) exposing RPC API to the exchange providing all needed functionality for transaction scanner and transaction executor (wallet/node equivalent)
h) serving undefined reporting services determined by bank law indirectly or by interfacing other services
i) executing end-of-day actions needed to update bank total balances and do all actions required by SEPA etc.
There should be separate CBS -plugin for each fiat currency and separate instance of CBS for each fiat currency. The CBS should consist of modules responsible for e.g. managing user accounts, communication with CBS-plugin, communication with Bank, queuing transactions. It should be possible to turn off some modules.
Each CBS-plugin will have separate configuration in the Exchange that defines available functionality in CBS(e.g. opening account).
