What is blockchain technology and how does it work?

working of blockchain technology

Blockchain is a digital ledger where data about transactions between two parties. It ensures data cannot be altered or deleted. And transactions are recorded and stored in chronological order using cryptographic techniques.

Banks are already experimenting with blockchain technology to lower costs for conducting transactions. Other use cases are to provide new services to consumers and verify the identity of companies. What are companies in other industries doing with blockchain? Let’s find out.

Core characteristics of Blockchain Technology

core characteristics of blockchain

A blockchain is a constantly growing collection of records known as blocks that are linked and guarded using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. 

This technology is highly secure by design, and they are an example of a distributed computing system with high Byzantine fault tolerance.

Following are the 4 properties of Blockchain.

1. Distributed

Distributed Ledger Technology (DLT) is a combination of technologies that allows multiple parties to record and update information on a shared digital ledger. 

It uses cryptography to enable each party to access the data only they are authorized to see and ensure everyone has access to an up-to-date version of the ledger. No centralized version exists, and no user controls it directly.

2. Open source

Blockchain is an open-source technology. Anyone can take the existing technology, modify it and create their own “fork.” However, it is worth noting that no one can claim ownership or authorship of the original software. 

This means that any modification made to blockchain technology risks being rejected by the global community.

3. Consensus mechanism

The consensus mechanism is a critical component of Blockchain. It is the process by which the node verifies and accepts the transactions in the Blockchain.

The nodes do not communicate directly with each other. Instead, they share a common reference point, i.e., a consensus mechanism.

4. Decentralization & transparency

There is no centralized database storing all the data; instead, it’s spread across a network of many different computers. Decisions about changes to the data are also made by consensus of the network participants. It ultimately ensures retaining transparency.

Blockchain Use Cases in Banking & Finance 

use cases of blockchain in finance

A growing number of financial institutions are experimenting with blockchain-based products using cryptocurrencies to handle transactions. 

1. International Payments

Banks use blockchain technology to create a permanent, public, transparent ledger for recording the movement of funds on a per-transaction basis. Using this public ledger, a financial institution can avoid the need for a customer to provide proof of their identity every time they make a transaction.

2. Capital Markets

The issuer creates a smart contract on a blockchain that defines the new security conditions to be issued and traded. The smart contract is then linked to new digital security, for example, a token that can be listed and sold on the new blockchain platform.

The platform then manages the security lifecycle from beginning to end, from subscription to trade maturity, by providing marketing, distribution, settlement, and custody services.

3. Trade Finance

Traditional trade finance processes take up to 45 days, and cross-border transactions can stretch to 60 days. This inhibits the business process and may result in missed business opportunities for both importers and exporters.

This technology can drastically increase the speed of trade finance processes by offering a real-time settlement.

4. Money Laundering Protection

A new way to stop money laundering and ensure that the people, banks, and companies providing services to you are who they say they are using smart contracts. It enables businesses to harness the power of blockchain technology to identify the ultimate beneficial owner(s) of a bank account – providing unprecedented transparency, traceability, and security.

5. Peer-to-Peer Transactions

Peer-to-peer transactions (p2p) are transactions made directly between two parties, peers, without an intermediary. All this info is stored in a decentralized blockchain, which is not controlled by one central power or authority helps to make the transaction process hassle-free.

Blockchain Applications in Business
