Blockchain is perhaps best-known as the technology underpinning cryptocurrencies like Bitcoin.
But Blockchain – which can be summarised as a digital ‘ledger’ or collection of transactions that are duplicated and distributed across a network of computer systems, making them difficult or even impossible to hack or alter – is being used in a variety of ways.
They include ways to make companies more efficient, such as by automating complex worker payment systems; making supply chain lines from fashion to food more transparent and traceable; and even ensuring the safety of pharmaceuticals sold to customers.
These uses are not all being trialed by startups or small, niche companies. Many large businesses are investigating the potential of blockchain or making it a major product offering; in fact, a recent survey by Blockdata found that 81 of the biggest 100 listed companies are using Blockchain technology in some form. Other public companies are also heavily invested in cryptocurrencies like Bitcoin, which are built on the Blockchain.
Here are 10 of the world’s biggest listed firms, across different fields, that are pioneering Blockchain use, and what they are achieving with it.
