Proof of Work (PoW) System Overview

Overview

This document provides a high-level overview of a blockchain network utilizing the Proof of Work (PoW) consensus mechanism. The following sections detail the main components of the system, their roles, and interactions.

System Overview

The blockchain network described herein involves multiple interacting components that ensure secure and reliable transaction processing and block validation through PoW.

Components

Clients

• Description: Users or external systems that initiate transactions within the blockchain network.
• Interactions:
  • Submit new transactions to various nodes in the network.

Nodes (A, B, C, D)

• Description: These are the active entities within the blockchain that receive, validate, and propagate transactions and blocks.
• Interactions:
  • Validate and broadcast transactions to ensure network consensus.
  • Propose and validate new blocks to be added to the blockchain.

Miner Node

• Description: A specialized node responsible for the computational work needed to confirm blocks (Proof of Work).
• Interactions:
  • Conducts the Proof of Work for new blocks.
  • Validates and adds confirmed blocks to the blockchain.

Validated Block

• Description: A representation of successfully validated blocks through PoW.
• Interactions:
  • Added to the blockchain and propagated across all nodes.

Shared Database

• Description: A metaphorical representation of the blockchain itself, which is a distributed ledger shared across all nodes.
• Interactions:
  • Receives updates when new blocks are validated and ensures all nodes have the latest and consistent version of the blockchain.

Diagram

The system interactions are depicted in the diagram included at the beginning of this document. This diagram provides a visual representation of how each component interacts within the network.

Transactions

• Broadcast Transaction: Ensures all nodes in the network have the same data by propagating transactions across the network.
• Update All Nodes: After a new block is successfully added, the blockchain updates all nodes to reflect the new state, ensuring consistency and reliability.
