This five-day course provides a highly practical advanced blockchain training on Hyperledger Fabric. Every student gets experience in developing blockchain applications on Fabric. By the end of the course, the participant will design an application and learn how to integrate it with external file storages. 

Course taught by an a Blockchain expert.
