Financial theorists continue to argue whether Blockchain is a disruptive technology in the Financial Services space, it has quietly gone mainstream with a wide variety of industries including the financial services industry. There are organizations and consortiums focused on developing blockchain solutions and the solutions have astounding ramifications for the industry.

So what is Blockchain? Blockchain is a process of creating a chain of blocks containing transactions that are encrypted, thereby creating a ledger of transactions. A block once created and added to the existing blocks is permanent and cannot be changed. Entities which create a block are called nodes. Once a block is created by a node, then it is shared/available for use by other nodes. Each node adheres to the standard for storage of transaction data and can have full copy of the data. This is referred to as “Distributed Ledger”.

There are standards and rules defining how nodes can exchange Blockchain information and mathematical rules for all nodes to agree regarding the integrity of data. This is done to ensure that all transactions are validated and all valid transactions are added only once. Cryptography is implemented through a combination of public and private keys. Nodes validate the transactions to avoid double accounting. Also, there is a provision to add dynamic programmable outcomes based on an event. For e.g. trigger payment upon reaching the interest payment date for a bond.

Access to the Blockchain network to perform the role of the node can be classified as either permissioned or permission-less. Permissioned Blockchain refers to scenario where only certain parties are allowed access to the Blockchain network. Permission-less Blockchain refers the contrary wherein there is no restriction on who can perform the role of the node i.e., to validate the transactions and adding the instructions to ledger.
