U.S. Patent 10795644 was awarded on October 06, 2020 and is entitled “Decentralized random number generator.” The first named inventor is Xiaohu Chen of Mountain View, CA. The abstract contains an overview of the patent disclosure:

The current disclosure is directed towards efficiently generating random sequences on a large-scale peer-to-peer network. In one example, the disclosure provides for selecting a first node based on a block generation order, where the first node is selected to generate a current block, adding a first signature share of the first node to the current block, adding at least a second signature share from a previously selected node to the current block, generating a random sequence based on the first signature share and the second signature share, adding the random sequence to the current block, and publishing the current block to a blockchain maintained by a node pool. In this way, a random sequence may be generated on-chain, with linear messaging complexity, without relying on a single trusted party/apparatus, which may thereby decrease a probability of any single party controlling the random sequence produced.
