Distributed Ledger Technology: beyond block chain (PDF) (Report). UK Government, Office for Science.
A distributed ledger is a consensus of replicated, shared, and synchronized digital data
geographically spread across multiple sites, countries, and/or institutions. Users of Distributed
Ledger Technology (DLT) significantly benefit from the efficiencies and economics by creating a
more robust environment for real-time and secure data sharing. Contrary to common belief, the
Bitcoin blockchain is not the only distributed ledger, in fact, many other users of Distributed
Ledger Technology use different methodologies to achieve the same consensus (e.g. Ripple,
MultiChain, HyperLedger Project).
