How does ChainGPT work?

Could you elaborate on the workings of ChainGPT? I'm particularly interested in understanding how it leverages blockchain technology and how the GPT component integrates into the overall framework. Specifically, how does ChainGPT ensure secure and transparent transactions while maintaining the flexibility and intelligence of a generative pre-trained transformer? What are the key mechanisms and processes that drive its functionality? And how does it ensure scalability and efficiency as the network grows? Understanding the nuts and bolts of its operation would help me evaluate its potential applications and use cases.
