As a new technology stack

blockchain applications are infiltrating into different financial scenarios

by exerting disruptive effects. At the same time

they are facing various challenges

from technical limitations

security and extensibility requirements

to policy restrictions. Rational thinking is essential

which involves understanding the essence of blockchain technologies

knowing how to apply technology to the appropriate scenario

recognizing major safety and scalability bottlenecks andbeing prepared for different levels of risks that may arise and solving the technological challengesand assisting to build the regulatory legal system. In launching a project of financial blockchain as a service platform

a three-step systematic solution is proposed. Firstly

usingthe model-driven architecture in system modeling and software architecture design

different perspectives of technologies and business processesare separated. Secondly

an open and win-win ecology is constructedby building an one-stop BaaS Platform system. Thirdly

multi-chain technologies are appliedto meet the different business requirements. This projectsuccessfully verifies the feasibility and reliability of cross-organization blockchain alliance in a real-world scenario of technology finance. Looking into the future

blockchain technologies can achieve more practical applications in more areas

for example

in financial sectors

digital assets

supply chains

shared economy and so on.
