Blockchain as a service
Blockchain-as-a-Service allows businesses to use cloud-based solutions to build, host and use their own blockchain apps, smart contracts and functions on the blockchain infrastructure developed by a vendor. Just like the growing trend of using Software-as-a-service where access to the software is provided on a subscription basis, BaaS provides a business with access to a blockchain network of its desired configuration without the business having to develop their own Blockchain and build in-house expertise on the subject.
Many major cloud services providers now provide Blockchain-as-a-Service, including IBM, SalesForce, Microsoft, Amazon, Alibaba, Oracle and Baidu to name a few. Blockchain-only focused companies offering Blockchain-as-a-Service include Bloq, Factom, Kaleido, and Dragonchain
