Abstract
A technical solution for providing data associated with a predetermined, finite lifetime for access via a distributed ledger is provided. A member computing entity receives a submission provided by a supplying member computing entity associated with a supplying member of a distributed ledger; generates a token and attributing the token to a member account corresponding to the supplying member; attributes a value to the token; and makes the submitted instance of data available for access via the distributed ledger. The submission comprises a submitted instance of data. The submitted instance of data (a) is configured to be provided to a consuming member computing entity via the distributed ledger and (b) is associated with a predetermined lifetime. The value of the token changes with time based on (a) a remaining lifetime of the submitted instance of data, (b) a depreciation policy/protocol corresponding to the distributed ledger, or (c) both.
