Distributed Ledger Technology Systems by Michel Roux is a comprehensive reference on distributed ledger technology (DLT). This book attempts to provide a comprehensive and in-depth look at the concepts, applications, and impacts of this technology. A distributed ledger, or DLT, is a technology system that stores and manages information across a distributed network of computers and servers. This technology is particularly well-known for blockchain, which is a type of DLT. Using cryptographic algorithms and rules agreed upon by the network, DLT allows transactions to be recorded and verified without the need for trusted intermediaries.
