Description 

Today, most users adopt Blockchain in order to collaborate with each other, however, it is difficult to manage a large blockchain network because of multiple organizations and nodes. 

Hyperledger Cello is aiming to resolve the following challenges, 1) Facilitate creation of blockchain network, can help user without blockchain background to setup their network nodes quickly. 2) Cross organization communication, can connect blockchain networks among multiple organizations. This project targets to design and implement a practical operational system equipping with decentralized functionalities to solve above challenges, based on Hyperledger Cello code base.
