Introduction

In the realm of blockchain development, managing historic data is crucial for maintaining the integrity and accuracy of a system. The RegistrationChain type, a fundamental component of the rbac-registration crate, requires a robust mechanism to store and handle historic data. In this article, we will delve into the process of updating the RegistrationChain to accommodate historic data for x509_certs, c509_certs, simple_keys, and role_data.

Understanding the Problem

The existing implementation of RegistrationChain relies on tuples to store data, which can lead to inefficiencies and difficulties in managing historic data. The current structure of RegistrationChainInner uses a HashMap to store x509_certs, c509_certs, simple_keys, and role_data fields. However, this approach has limitations, particularly when it comes to handling historic data.

Refactoring the `RegistrationChain`

To address the limitations of the existing implementation, we will introduce a new structure, PointedData<T>, which will replace the tuples used to store data. The PointedData<T> structure consists of two fields: point and data.

struct PointedData<T> {
  point: PointTxnIdx,
  data: T,
}

The PointedData<T> structure allows us to decouple the data from its corresponding point, enabling us to store and manage historic data more efficiently.

Updating the `RegistrationChainInner`

The existing RegistrationChainInner type will be refactored to use a HashMap<usize, Vec<PointTxnIdx<T>>> instead of a HashMap of tuples. This change will enable us to store multiple points for each data type, facilitating the management of historic data.

struct RegistrationChainInner {
  x509_certs: HashMap<usize, Vec<PointTxnIdx>>,
  c509_certs: HashMap<usize, Vec<PointTxnIdx>>,
  simple_keys: HashMap<usize, Vec<PointTxnIdx>>,
  role_data: HashMap<usize, Vec<PointTxnIdx>>,
}

Benefits of the Refactored `RegistrationChain`

The updated RegistrationChain offers several benefits, including:

Improved data management: The PointedData<T> structure enables us to decouple data from its corresponding point, making it easier to manage and store historic data.
Efficient storage: The use of a HashMap<usize, Vec<PointTxnIdx<T>>> allows us to store multiple points for each data type, reducing storage requirements and improving data retrieval efficiency.
Enhanced scalability: The refactored RegistrationChain is more scalable, as it can handle a larger volume of data and points without compromising performance.

Implementation Details

To implement the refactored RegistrationChain, we will follow these steps:

Create a new PointedData<T> structure: Define the PointedData<T> structure with the point and data fields.
Refactor the RegistrationChainInner type: Update the RegistrationChainInner type to use a HashMap<usize, Vec<PointTxnIdx<T>>> instead of a HashMap of tuples.
Update the RegistrationChain type: Modify the RegistrationChain type to use the refactored RegistrationChainInner type.
Implement data management logic: Develop logic to manage and store historic data using the PointedData<T> structure and the refactored RegistrationChainInner type.

Conclusion

In conclusion, updating the RegistrationChain to store historic data for x509_certs, c509_certs, simple_keys, and role_data requires a comprehensive approach. By introducing a new PointedData<T> structure and refactoring the RegistrationChainInner type, we can improve data management, efficient storage, and scalability. The implementation details outlined in this article provide a clear roadmap for updating the RegistrationChain and managing historic data effectively.
