Decentralized Random Number Generator

A method of generating a random sequence in a node pool, the method comprising:

• selecting a first node of the node pool based on a block generation order;
• receiving a plurality of signature shares at the first node;
• responsive to the plurality of signature shares exceeding a threshold number of signature shares:
• determining a threshold signature;
• generating a random sequence based on the threshold signature;
• and
• broadcasting a block to the node pool, wherein the block comprises:
• the plurality of signature shares;
• the threshold signature;
• and
• the random sequence.

A node within a node pool comprising:

• a network interface;
• a memory;
• and
• a processor communicatively coupled to the network interface and the memory, the processor configured to:
• receive a plurality of signature shares from the node pool via the network interface;
• responsive to the plurality of signature shares exceeding a threshold number of signature shares:
• determine a threshold signature;
• generate a random sequence based on the threshold signature;
• and
• broadcast a block to the node pool via the network interface, wherein the block comprises:
• the plurality of signature shares;
• the threshold signature;
• and
• the random sequence.
