Anyone can access the ledger and view any transaction and, as the transactions are verified and replicated in multiple locations, the network is very resilient. The blockchain provides accountability but is also decentralised – which is why it can be used on a potentially massive digital scale, going way beyond digital currency.

While blockchain technology still has some work to do to convince stakeholders of its credentials, particularly around security, its distributed nature and transparent ledger offer benefits that could be used in a range of applications.

Banks, regulators and corporations around the world are now looking seriously at its potential. Nasdaq is already using it; IBM is testing it for the “Internet of things”; other companies are looking at how it might help keep passwords and secure documents safe from hackers; others are saying
