A defining feature of the prevalent digital currency systems is the large set of full records each system maintains of the system's transactions, often referred to as the blockchain. While the design of these systems typically makes these records broadly accessible, the records are largely anonymous, providing only basic details about each transaction and its counterparties. These limitations have been important for making digital currency systems widely scrutinizable and transparent while also attractive to users who wish to preserve their privacy.
