Creating blocks in instance blockchain base on a promised block in a generic blockchain

A system, comprising:

• a memory;
• a processor communicatively coupled to the memory, wherein the processor is configured to perform:
• storing, in a blockchain system, at least one generic finite blockchain comprising representative blocks, each corresponding to a step in a multi-step process;
• dynamically generating at least one finite blockchain instance based on said at least one generic finite blockchain;
• operating the system in a first mode wherein a first block is created in the finite blockchain instance based on change evidence data pertaining to at least one step in said multi-step process;
• wherein the change evidence data comprises information indicating that the step has completed;
• and recording the change evidence data in the first block;
• and
• operating the system in a second mode comprising identifying a promised block in the at least one generic finite blockchain, wherein the promised block corresponds to a successive step in the multi-step process that is dependent on a prior step in said process corresponding to a preceding block in the at least one generic finite blockchain;
• and creating a block in the at least one finite blockchain instance corresponding to the promised block based on a likelihood that the prior step will complete.10. The system of claim 9, further comprising associating each of the first and second bloc chain instances to a corresponding generic finite blockchain.

A non-transitory computer program product comprising a computer-readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform:

• storing, in a blockchain system, at least one generic finite blockchain comprising representative blocks, each corresponding to a step in a multi-step process;
• dynamically generating at least one finite blockchain instance based on said at least one generic finite blockchain;
• operating the system in a first mode wherein a first block is created in the finite blockchain instance based on change evidence data pertaining to at least one step in said multi-step process;
• wherein the change evidence data comprises information indicating that the step has completed;
• and recording the change evidence data in the first block;
• and
• operating the system in a second mode comprising identifying a promised block in the at least one generic finite blockchain, wherein the promised block corresponds to a successive step in the multi-step process that is dependent on a prior step in said process corresponding to a preceding block in the at least one generic finite blockchain;
• and creating a block in the at least one finite blockchain instance corresponding to the promised block based on a likelihood that the prior step will complete.
