Accelerate your Development using Azure Blockchain Workbench

Azure Blockchain Workbench is free, easy to use tool to create decentralized blockchain applications. It is a set of Azure service, which helps you deploy the blockchain applications. It enables you to share the business processes and related data with other organizations. The business logic is unique for each type of business; this logic is the base of creating smart contracts.

A blockchain is a decentralized public digital ledger. It records transactions in blocks across multiple computers making alteration of all subsequent blocks impossible. The appending method and the latest displayed on top make the record access easy.

Developing Blockchain programs are simpler as the data, neither replaced nor overwritten. The copies and versions with details are stored as proof of action by each involved party. It reduces the communication overdose. The best use of blockchain technology is in the supply chain, cryptocurrencies, smart contracts, financial services and gaming.
