Blockchain

Bitcoin is a remarkable cryptographic achievement, and the ability to create something
that is not duplicable in the digital world has enormous value. Eric Schmidt, CEO of Google,

What is Blockchain?

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system.

A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT).

All the transactions and data are attached to the block after the process of maximum trust verification. There is a consensus of all the ledger participants on what is to be recorded in the block.

With the smart contracts, the businesses can pre-set conditions on the blockchain. The automatic transactions are triggered only when the conditions are met.

The transactions stored in the blocks are contained in millions of computers participating in the chain. Hence it is decentralized. There is no possibility that the data if lost cannot be recovered.

The blockchain technology allows for verification without having to be dependent on third-parties.

It uses protected cryptography to secure the data ledgers. Also, the current ledger is dependent on its adjacent completed block to complete the cryptography process.

The data structure in a blockchain is append-only. So, the data cannot be altered or deleted.

The transactions that take place are transparent. The individuals who are provided authority can view the transaction.

The ledger is distributed across every single node in the blockchain who are the participants. So, it is distributed.

Since various consensus protocols are needed to validate the entry, it removes the risk of duplicate entry or fraud.

Blockchain in Banking sector

Bank services such as deposits and loans may see an increase in their reliability as distributed ledgers and smart contracts available with blockchain technologies are used. In addition, the same technologies can be applied to foreign exchange businesses. International remittances and issuances of letters of credit and management in trade can proceed at lower cost and higher speeds. For example, Ripple coin (XRP) effects within blockchain technology are considered to be substantial. Ripple is a real-time gross settlement system as well as a currency exchange and remittance network created by Ripple Labs, a US-based technology company.
