Technology is never a sector to shy away from hype, and in the last few months one area has received more than its fair share: blockchain.
Blockchains store data across numerous 'blocks' rather than on one central server, with new information only being entered into the 'chain' once a cryptographic key has been solved by a computer. For this reason blockchain is also known as distributed ledger technology (DLT). Information on the blockchain cannot be erased, meaning it offers a definitive record of digital events.
A growing number of startups around the world are exploring how to harness the power of blockchain technology for a plethora of different purposes.
