Linked blockchain structures for accelerated multi-chain verification

A method comprising:

• storing, in memory, blocks of an enterprise delivery blockchain, wherein a block of the enterprise delivery blockchain includes an acceptance report indicating adherence to a contractual agreement, including operability of a product in a service provided by a service provider;
• accessing, with a processor, the block in the enterprise delivery blockchain;
• retrieving, with the processor, the acceptance report from the block in the enterprise delivery blockchain;
• determining an identifier, identified in the block in the enterprise delivery blockchain, to a block in an acceptance blockchain;
• accessing the block in the acceptance blockchain via the determined identifier;
• retrieving, from the block in the acceptance blockchain, contextual information of the acceptance report, wherein retrieving the contextual information comprises retrieving information indicative of how many times a product acceptance criterion within the acceptance report has been evaluated to be of sufficient quality to be accepted;
• outputting the acceptance report and contextual information of the acceptance report to a client of the service provider;
• receiving, from the client, feedback related to whether the acceptance report provides sufficient information for the client to determine whether the product adheres to the contractual agreement;
• and
• adding the feedback to the contextual information.

A computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to:

• access a block of blocks in an enterprise delivery blockchain stored in memory, wherein the block of the enterprise delivery blockchain includes an acceptance report indicating adherence to a contractual agreement, including operability of a product in a service provided by a service provider;
• retrieve the acceptance report from the block in the enterprise delivery blockchain;
• determine an identifier, identified in the block in the enterprise delivery blockchain, to a block in an acceptance blockchain;
• access the block in the acceptance blockchain via the determined identifier;
• retrieve, from the block in the acceptance blockchain, contextual information of the acceptance report, wherein retrieving the contextual information comprises information indicative of one or more product acceptance criteria, information indicative of how many times the product acceptance criteria has been used, and information indicative of how many times a product acceptance criterion within the acceptance report has been evaluated to be of sufficient quality to be accepted;
• output the acceptance report and contextual information of the acceptance report to a client of the service provider;
• receive, from the client, feedback related to the quality of the acceptance report, wherein the quality of the acceptance report relates to whether acceptance report provides sufficient information for the client to determine whether the product adheres to the contractual agreement;
• and
• add the feedback to the contextual information.
