Corda is a Distributed Ledger Technology to be used by businesses, such as financial institutions, to keep a shared ledger of transactions and thus removing the need for the involved parties to constantly check that each of their books are in line after interacting with each other. Corda is designed to removes the need for all parties on the Corda network to know about each and every transaction, as only those involved are interested in them. Here is an example that shows how Coda works:
When a business or financial institution, a bank for this example, transfers money from a client’s account to the receiver’s account in another bank both must check that what was sent was valid, that the funds from the client have been sent and finally that they were received correctly. Ensuring that the funds have decreased in one account and increased in the other requires multiple checks from both sides of the transaction as they need to be 100% sure that money hasn’t magically disappeared or created out of thin air. Furthermore, a number of these checks are done manually, requiring even more time and effort to ensure consistency.
