Abstract
An example operation may include one or more of generating an initial seed and allocating one or more authorized bits of the initial seed to a plurality of blocks in a distributed ledger, storing the initial seed and an identification of which authorized bits of the initial seed are allocated to each block of the distributed ledger, receiving a final seed value that is partially generated by each of a plurality of nodes configured to access the distributed ledger based on authorized bits of respective blocks updated by each respective node, and generating a random sequence value based on the final seed value and storing the random sequence value in a block of the distributed ledger.
