S. 4109 would require the Office of Science and Technology Policy (OSTP), in consultation with other federal and nonfederal entities, to develop a strategy for research and development on distributed ledger technology, which enables the use of shared data structures that are synchronized in multiple places. The bill would direct OSTP to submit the plan to the Congress and the President within one year of enactment. Based on the cost of similar activities, CBO estimates that implementing S. 4109 would cost $1 million over the 2023-2027 period. Such spending would be subject to the availability of appropriated funds.
