IBM's Blockchain Platform is the company's BaaS solution that it delivers through the IBM Cloud. It simplifies the process of deploying a blockchain-enabled application. IBM's platform has a number of unique features. These include, a pluggable architecture that allows developers to use software modules and a new consensus algorithm, that IBM developed, and is tailored to specific use cases. It also enables cryptographic identity management and smart contracts that can be written in popular programming languages, such as Java, and then executed in containers.
IBM is also involved with the Linux Foundation’s open-source Hyperledger Project, which was created to help developers easily build secure distributed ledgers that can be used to exchange almost anything of value.
