Problem Description

Describe the problem you are trying to solve here.

I need a solana program modified. The current code allows for registering a node and updating its status, but it is designed to work with a single account for each invocation of the process_instruction function. This means that each invocation of the Register instruction will only register a single node in a specific account. -- It needs to allow for multiple nodes to be registered

Need a small UI to display the list of registered nodes and various status data.

Acceptance Criteria

Be specific about what you want in the solution here.

Update solana code to enable multiple nodes are be registered and updating at the metadata.

Small React UI to read this solana program and display the current state for each registered node.
