摘要
Blockchain and other distributed ledger technologies(DLTs)have demonstrated features such as decentralisation,replication,transparency,timestamping,immutability,digital signatures,automation and smart contracts.Through recent development,these technologies 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.Many popular applications are cloud related.Besides the widely used applications in financial sector,there are recent advances in internet applications that can harness these featured building blocks to empower users to take control of their online footprint,such as in healthcare,social media and other digital services.
