This report suggests that blockchain technologies and their underlying concepts have the potential to deliver sustainable infrastructure by unlocking opportunity along the infrastructure value chain. Instead, these functions are accomplished by decentralising the network in which data is stored and by providing a validation mechanism through which all participants in the network have an immutable single “source of truth”. The so-called “smart contracts” which are enabled by blockchain technology allow for the automated execution of a transaction when one or more preconditions are met, thus providing a potential for significant efficiency gains.
