When IBM joined the Hyperledger movement as a founding corporate member in 2016, it was already working on a blockchain framework that was integrated into the Hyperledger project and became the Fabric module. Original motivations for this initiative came from two observations made by the IBM team:
- Bitcoin and Ethereum are barely scalable due to several drawbacks (an energy-consuming consensus protocol, a growing permissionless network, and an increasing database size).

Since IBM spearheads most developments of Hyperledger Fabric by having contributed much of the code, it was expected that their solution called IBM Blockchain unveiled in March 2017 would make use of this specific module. This cloud-based solution enables developers to build robust and effective networks with improved security features...
