Bitcoin transactions were the first transactions recorded using blockchain technology. As a result of the efficiency and security of the Bitcoin blockchain, blockchain technology is now being applied far beyond crypto exchanges.

Take a closer look at what is new in blockchain innovation and what leading UK blockchain companies are doing in 2022.

What is blockchain technology and how does it work?

Blockchain technology is a digital ledger that validates and records transactions securely without requiring a central authority or intermediary. Tether, Bitcoin, Ethereum and other cryptocurrencies are built on this technology.

An online file containing a group of transactions is known as a ‘block’. In a chronological and linear ‘chain’ of records, blocks are linked together. Three main pieces of information are contained in each block: the details of the transactions themselves, a unique ‘hash code’ that identifies the block, and the previous block’s hash code.

It is impossible to remove or modify a block once it has been added to the chain. Changing the block will result in a new hash code being generated, and this new hash will conflict with the one in the following block. It explains how blockchain technology protects digital assets and ensures they cannot be stolen.

The UK’s high-growth ecosystem is rapidly adopting blockchain technologies despite scalability issues (blockchain systems require a lot of computational power), lack of regulation, and environmental concerns.

UK startups making it in blockchain.

In the UK, there are some 250+ high-growth companies that are developing blockchain-driven software and blockchain services. This sector is relatively new as most startups are still in the seed stages of their development.

While blockchain technology can be used for a wide range of applications, most blockchain-based tech companies focus on the business and professional services sector. In the UK, blockchain technology is being used to disrupt traditional business processes, particularly in banking and financial services, including fintech companies and challenger banks.

According to Beauhurst’s research, a number of innovative businesses have made the UK’s top blockchain companies list for 2022.
