Chapter 4. Planning Your BTA
After reading Chapters 1 through 3, you are now prepared to start building your own blockchain tethered AI system (BTA). This chapter helps you get the scope for setting up your Oracle Cloud instance and running your model (Chapter 5), instantiating your blockchain (Chapter 6), running your BTA (Chapter 7), and testing the completed BTA (Chapter 8).
The BTA is built by interweaving the MLOps process with blockchain in such a way that the MLOps system requires blockchain to function, which results in the AI being tethered. To do this, the BTA integrates blockchain with MLOps so that a model must be approved in order to proceed through the cycle of training, testing, review, and launch. Once a model is approved, it advances to the next step of the cycle. If it is declined, the model goes back to the previous steps for modifications and another round of approvals. All of the steps are recorded in the blockchain audit trail.
To plan for a system like this, you need to consider the architecture of the BTA, the characteristics of the model you are trying to tether, how accounts and users are created and how permissions are assigned, and the specifics of how and why to record certain points on blockchain.
BTA Architecture
The BTA has three major layers in its architecture: the BTA web application, a blockchain network, and the buckets.
Alongside the BTA, you will use a Jupyter Notebook, which is a Python development environment that helps you to build and ...
