System and method for a blockchain based automated certifiable workflow process

A system implementing a blockchain network for distributing at least maintenance information related to an aircraft service, the system comprises:

• a plurality of trusted agents executing permissions to participate in the blockchain network to interconnect amongst each other to perform a series of actions at least comprising:
• accessing, reading and writing transactions associated with the blockchain network;
• and
• a multi-layer workflow architecture for the blockchain network comprising:
• a first layer for creating permissions for the blockchain network, a second layer for orchestrating the workflow of the blockchain network, and a third layer for interfacing with the blockchain network and a distributed ledger,
• wherein the first layer further comprises:
• an activity interpreter engine using a set of machine interpretable activity bytecodes to provide functions in the blockchain network to input data for a current activity related to the aircraft service and to identify a particular trusted agent for the current activity, and an activity verifier engine using another set of machine interpretable activity bytecodes to identify the trust agent with permissions to approve a particular activity, determine a validation mechanism, and validate the inputted data,
• wherein the second layer further comprises:
• an activity orchestrator with machine readable inter-task functions to schedule the current activity from a plurality activities in the blockchain network,
• wherein the third layer further comprises:
• a plurality of adapters to read data from a distributed ledger of the blockchain network associated with each trusted agent and to interface with at least the activity interpreter and verifier engines.

A method for administering aircraft maintenance and verification, usable by a plurality of different entities each having different roles and each employing at least one computing device capable of networked communication, comprising:

• configuring a blockchain network for permissioned use by the plurality of different entities via networked communication;
• storing, in the blockchain network, at least one deployable workflow as a data structure specifying aircraft maintenance and verification-related activities and associated validation rules to be performed by at least selected ones of the plurality of different entities;
• deploying a distributed rule processing engine across the plurality of different entities and hosted at least in part by the at least one computing device of each of the plurality of different entities;
• hosting the distributed rule processing engine on the at least one computing device at each of the plurality of different entities implementing a workflow processing engine having:
• accessing, by an activity interpreter processing engine, the blockchain network on behalf of a hosting entity to retrieve the at least one deployable workflow, to select and perform at least one activity designated for the hosting entity and to cause a transaction record to be written to the blockchain corresponding to the performed activity;
• and
• accessing, by an activity verifier processing engine, the blockchain network on behalf of a validation compliance entity to retrieve at least one validation rule, to select and perform at least one validation rule and to cause a transaction record to be written to the blockchain corresponding to the results of performance of the at least one validation rule.
