Blockchain-based consensus process

A computer-implemented 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 one or more operations comprising:
• providing a plurality of process smart contracts, wherein each of the plurality of process smart contracts is configured to execute on a first blockchain, each process smart contract includes programming codes for implementing a process that includes two or more steps, at least one of the steps involves determining whether a consensus is reached regarding whether to approve or reject an item, and at least one of the steps involves performing an action based on the determination of whether a consensus is reached;
• providing a plurality of consensus smart contracts, wherein each of the plurality of process smart contracts is configured to execute on a second blockchain, each consensus smart contract includes programming codes for implementing a process for determining consensus among a plurality of consensus nodes according to one or more consensus rules, each consensus smart contract includes a public key, wherein a private key of the consensus smart contract corresponding to the public key is stored in a key management system associated with the second blockchain;
• and
• for each process smart contract, calling one or more consensus smart contracts, wherein each consensus smart contract is configured to determine whether a consensus is reached among a plurality of consensus nodes, wherein a same consensus smart contract is called by multiple process smart contracts,
• wherein the consensus smart contract uses the private key of the consensus smart contract to digitally sign a message requesting a vote on whether to approve or reject an item, and sends the message that is digitally signed to the plurality of consensus nodes,
• wherein the public key of the consensus smart contract enables the consensus nodes to validate the message sent from the consensus smart contract, and
• performing an action based on a result of the determination of whether a consensus is reached.

• wherein the consensus smart contract uses the private key of the consensus smart contract to digitally sign a message requesting a vote on whether to approve or reject an item, and sends the message that is digitally signed to the plurality of consensus nodes,
• wherein the public key of the consensus smart contract enables the consensus nodes to validate the message sent from the consensus smart contract, and
• performing an action based on a result of the determination of whether a consensus is reached.
