Recent headlines haven’t painted blockchain in the best light. It is often bundled in with cryptocurrency, as evidenced by last year’s crypto failures including Terra Luna’s collapse, followed by Three Arrows Capital and Celsius, plus FTX’s implosion amid allegations of large-scale fraud involving client funds.

This caused net trust in the cryptocurrency space across 17 major markets to decline by 30% on average, according to figures from Morning Consult. The blockchain, however, is the technology on which cryptocurrency runs and isn’t inherently the root cause behind the above scandals and failures.

A decentralised, distributed ledger tracks, stores and verifies transactions across multiple nodes (or computers). They are recorded in such a way that the registered transaction cannot be altered retroactively. That’s a significant difference between a traditional database where information is held centrally. The blockchain also makes it impossible for any single person or entity to control all the nodes.

As a relatively new technology – it was only invented in 2008 – its use cases have ebbed and flowed. The banking and finance sectors have explored using blockchain technology to pivot traditional pillar banks into the fintech and neo-banking space, but it has many use cases beyond finance.

Many big and household-name companies, including Google, Amazon, PayPal and Facebook, have looked at ways to adopt blockchain technology.

Proponents say it has applications that span across health, education, and government functions, where elements such as health and medical records or citizen data also need to be kept secure. Other uses include logistics, advertising, retail, NFTs, and music rights and royalties.

The snowballing value of blockchain technology has been predicted by Gartner to reach $176bn in revenue by 2025 and $3.1tn by 2030. When it comes to jobs, the blockchain market is expected to have 40 million jobs worldwide by 2030, and it is a field where high salaries are common. For example, blockchain engineers in London earn an average salary of £98,107.
