Event-driven blockchain workflow processing

A non-transitory computer-readable storage medium storing one or more instructions executable by a computer system to perform processing comprising:

• receiving, at a workflow processing node in a blockchain network from a client, a request to execute a workflow program, wherein the workflow program is stored in a blockchain maintained by the blockchain network;
• identifying, by the workflow processing node, an operation associated with the workflow program;
• assigning, by the workflow processing node, the identified operation to a subset of a plurality of nodes in the blockchain network, wherein each node in the subset of nodes is configured to execute the operation separately from the other nodes in the subset of nodes;
• identifying, by the workflow processing node, processing results for the executed operation associated with nodes in the subset of nodes, each processing result associated with a particular node in the subset of nodes and representing a result of the executed operation produced by the particular node;
• and
• determining, by the workflow processing node, a consensus result for the operation based on the identified processing results associated with a number of nodes greater than or equal to a consensus threshold matching the consensus result.

A system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform processing comprising:
• receiving, at a workflow processing node in a blockchain network from a client, a request to execute a workflow program, wherein the workflow program is stored in a blockchain maintained by the blockchain network;
• identifying, by the workflow processing node, an operation associated with the workflow program;
• assigning, by the workflow processing node, the identified operation to a subset of a plurality of nodes in the blockchain network, wherein each node in the subset of nodes is configured to execute the operation separately from the other nodes in the subset of nodes;
• identifying, by the workflow processing node, processing results for the executed operation associated with nodes in the subset of nodes, each processing result associated with a particular node in the subset of nodes and representing a result of the executed operation produced by the particular node;
• and
• determining, by the workflow processing node, a consensus result for the operation based on the identified processing results associated with a number of nodes greater than or equal to a consensus threshold matching the consensus result.
