Blockchain: Decentralised technology for secure transactions

The blockchain is a decentralised, digital database that records transactions securely and transparently. It works by linking blocks of data that are stored in a network of computers, making manipulation virtually impossible. The technology is primarily used in the financial sector for cryptocurrencies such as Bitcoin, but is also used in other areas such as supply chain management, healthcare and digital contracts. Thanks to its security and transparency, blockchain has the potential to revolutionise many industries.
