Blockchain Frameworks to Build App

The blockchain is a proven technology that can be used anywhere. Interest in blockchain-based apps is increasing in all spheres. No matter the sphere you’re building software for — finance, commerce, healthcare, government, agriculture — you need to learn how to work with blockchains quickly and easily. For that, you have to choose a blockchain framework that meets your needs and fits your projects.

Below, you can find an examination of the six most useful blockchain frameworks and a comparison of their characteristics.


Exonum is a blockchain framework developed for enterprise projects and launched in 2017 by the Bitfury Group. The Exonum source code is absolutely open, as are all application programming interfaces (APIs). Exonum provides access not only to the whole codebase but to client software for blockchain management. It was built with the help of Rust, one of the safest and fastest programming languages. Rust is currently faster than Java, C, C++, and even Go.

As a developer, you can use Exonum to build solutions for FinTech, GovTech, LegalTech, and many other fields. The main characteristics of this framework are the following:

  • Exonum is an independent system, as it doesn’t require mining and doesn’t depend on any cryptocurrency.
  • Exonum blockchains work very fast, processing about 5,000 transactions a second.
  • Exonum has a Light Client that can check the availability and correctness of user data as well as the anchorage status of that data.
  • Exonum relies on services that work similarly to smart contracts but are more flexible and adaptable.

Companies that use Exonum-based apps for their financial systems also get another benefit: Exonum avoids the possibility of double-entry bookkeeping and all sorts of document forgery.
