Short answer, no.

Blockchain is not a specific technology, its a group of strategies and distributed consensus algorithms that chain and validate information together through (usually) encryption. There is no pattern to it, in the same way that there are no patterns to "integrations" when used as a generic concept.

That is not to say that you cannot interact with some API that a specific blockchain service or network provides. That will certainly involve manual routines in the same way most Genio extensions do. But "how" cannot be answered until a specific API is known.
