What is a P2P system and its architecture

1. Introduction

P2P architecture stands for Peer-to-Peer, which is a decentralized system where all devices share resources equally. This contrasts with client-server models where there is a central server. P2P systems are simpler and offer more equal interactions between devices.

2. Block Chain Layered Architecture

Traditional Internet Architecture versus Blockchain Network Architecture

  • Data Layer: Responsible for storing and managing data.
  • Network Layer: Handles the communication and connection between nodes.
  • Consensus Layer: Ensures all nodes agree on the state of the network.
  • Incentive Layer: Provides motivation for participants to contribute.
  • Contract Layer: Manages smart contracts that self-execute based on predefined parameters.
  • Application Layer: Where users interact with the blockchain.

    3. P2P Protocols and Communication

    Background: P2P protocols are essential for efficient communication and data security between nodes. They are widely utilized in file sharing, real-time communications, and streaming services.

    4. P2P in Practice: Case of Skype

    Skype is a prime example of a successful P2P application where indexes are distributed among super nodes. The decentralized nature of P2P systems ensures robustness and scalability.

    5. Dragonfly in Distribution Systems

    Dragonfly, an open-source tool by Alibaba, supports P2P distribution and integrates with the company's file systems. It enhances distribution systems' efficiency and reliability.

    6. P2P in Financial Sector: ITBT4.0

    ITBT4.0 is an online platform providing users with investment and funding opportunities. P2P lending platforms have evolved from offline to online models, showcasing the versatility and growth in the financial sector.

    7. KKP2P System Architecture

    The KKP2P system architecture comprises four main modules in the cloud. These modules manage routing information, online device communication, and provide a cohesive structure for P2P interactions.

    Overall, P2P systems offer a decentralized, collaborative approach to resource sharing and communication. With the growth of blockchain technology and the adoption of P2P protocols, the future holds promising developments in various sectors.
