Abstract: Systems and methods for intelligent and adaptive testing of a blockchain application to identify compliant code modifications. The method includes the steps of recording requests to and response from a baseline blockchain application receiving the requests from a plurality of application users. The same responses are input into a shadow blockchain application that includes a number of switch selectable new code segments. The switch selectable new code is enabled and disabled according to a pattern. The responses from the baseline application are compared against the response from the shadow blockchain application from when error vectors are generated. These error vectors are used to train a learning machine to determine which new code segments result in response errors or aberrations.

Abstract: Systems and methods for efficiently serving blockchain requests using an optimized cache are disclosed herein. An example method normalizing a request for blockchain data into a key, the request including a hash of a canonical head block of the blockchain data, searching a distributed key value store using the key, the distributed key value store comprising key value pairs, each of the key value pairs being associated with responsive blockchain data, determining when one of the key value pairs match the key, placing a pending job space for a job in the distributed key value store when one of the key value pairs is not found, and storing a new key value pair in the distributed key value store when a response for the request is obtained, the response being new responsive blockchain data.

Abstract: Embodiments of the invention build models to predict the likelihood of entities that operate in a given identifier space also operating in a disjoined identifier space based on a source panel of entities that operate in one or both of the identifier spaces. In operation, a model building engine builds a model based on features associated with the source panel and features associated with standard populations in the given identifier space. The model is used to determine whether the target entity is more similar to those entities in the source panel that operate only in the given identifier space or those entities in the source panel that operate in both identifier spaces.
