Solana Node Management and Task Dispatch Program

This project provides a Solana program and client application to manage nodes and dispatch tasks across nodes, built using Solana's Rust SDK. The program defines four main instructions:

1. RegisterNode: Registers a new node with a specified ID.
2. RemoveNode: Removes a node based on its ID.
3. DispatchTask: Dispatches a task to a node, specifying a unique task ID.
4. ReturnAnswer: Returns a response or answer from a node for a given task.

The project also includes a TypeScript client for interacting with the Solana program, making it easy to manage nodes and execute tasks directly from a client environment.

Prerequisites

• Node.js and npm: Required to run the TypeScript client.
• Rust and Cargo: Required to build and deploy the Solana program.

Note: For easy testing and deployment, you can use the Solana Playground, an in-browser development environment for Solana, eliminating the need for a full local Solana setup.

Quick Start Guide

Setting Up Solana Playground

Solana Playground provides a quick, convenient way to develop on Solana without a local setup.

1. Open Solana Playground.
2. In the bottom left corner, create or connect a wallet, which will be used for deploying and testing the program.
3. Copy or write the Rust code for your program in the Playground.
4. Use the Build button to compile the program.
5. Use the Deploy button to deploy the program to the Playground network, which assigns a PROGRAM_ID.
6. Copy the PROGRAM_ID, as you’ll need it in the client code to interact with the program.

Available Instructions

The client provides interactions for all four instructions in the Solana program:

RegisterNode: Registers a node by providing its ID. RemoveNode: Removes a node by ID. DispatchTask: Sends a task to a specified node. ReturnAnswer: Retrieves a response from a node for a dispatched task. These instructions are serialized and sent as transactions to the program, with nodeId and taskId as parameters.
