Blockchain and other distributed ledger technologies (DLTs), through recent development, have not only enabled simple transactions, but also complex computation on a network where parties are geographically distant or have no particular trust in each other to interact and exchange value and information on a fully distributed basis with fewer to non-existent central intermediaries. There are obvious advantages associated with blockchain in areas such as decentralization, disintermediation, replication, timestamping, immutability, digital signatures, automation and smart contracts, transparency and censorship resistance, especially in relation with the financial sector. However, there are also noticeable challenges, for instances, scalability and performance, energy consumption, security and privacy. Many popular applications are cloud related. These advances are now not just limited to the financial sector, but also new internet applications can harness these building blocks to empower users to take control of their online footprint, such as in healthcare, social media and other digital services.
