implementation of a smart contract on permissioned Blockchain for business

What is it about?

In this paper is proposed a solution for implementation of a smart contract, based on permissioned Blockchain Hyperledger Fabric. The implementation allows fast and secure migration of smart contracts between independent channels. Each channel has own business logic and it is invisible for participants in other channels. Experiments are made and test results are given.

Why is it important?

Permissioned Blockchains were introduced to solve the privacy and confidentiality problems in public Blockchain networks. The Blockchain business solution is implemented by providing a connection between its individual organizations, for storage and exchange of information, as well as for its processing. The data are visible only between the organizations that have access rights, for which channels of communication have been established between them. To maintain the correctness of the data during recording and storage, peers are configured within the organization to maintain the operability of the network.
