Top 19 Blockchain Companies in the UK

| Lucy Wilson

Blockchain is a digital ledger which enables transactions to be validated and recorded securely, without the need for a central authority or intermediary. Blockchain technology was first created to record the transactions of cryptocurrency Bitcoin. Such is the efficiency and security of the Bitcoin blockchain, however, that blockchain is now being applied far beyond crypto trading. We’ll take a closer look at the UK’s innovation landscape and the high-growth blockchain startups that look poised to grow this year. But first, what exactly is blockchain? 

What is blockchain and how does it work?

A ‘block’ is an online file which contains a group of transactions. Blocks are strung together in a chronological and linear ‘chain’ of records. Each block contains three main pieces of information: data about the transactions themselves, a unique ‘hash code’ which is used to identify the block, and the hash code of the previous block in the chain. Once a block has been added to the chain, it is immutable, meaning it cannot be removed or modified in any way. Any attempt to change the block will lead to a new hash code being created, and this new hash will conflict with the hash in the following block. This explains how blockchain technology works to ensure data is held securely and cannot be tampered with.

Despite scalability issues (blockchain systems require massive amounts of computing power), alongside concerns over its lack of regulation and environmental costs, blockchain adoption is increasing rapidly across the high-growth ecosystem

The UK’s blockchain business landscape

The UK is currently home to 221 private companies that are developing blockchain-driven software and blockchain services. The vast majority (67%) of these companies are currently in the seed stage of growth—a reflection of how new the sector is. 

Whilst blockchain has a broad range of use cases, 41% of blockchain-based tech companies are operating in the Business and Professional Services industry, primarily in banking and financial services, but also security services, analytics, payment processing, insurance and law. In comparison, 2% operate in the Supply Chain sector, 2% in Leisure and Entertainment, and just 1% in Retail and 1% in Industrials. This illustrates the growing use of blockchain technology by UK startups to disrupt traditional business processes

We explain blockchain’s distributed ledger technology (DLT) in greater detail for you here, alongside how the Bitcoin blockchain works, and which industries blockchain looks set to disrupt in the future. 

Meanwhile, here’s a rundown of the most exciting blockchain companies to watch in 2021…
