The Role Of P2P In Blockchains

In the early stages of Bitcoin, Satoshi Nakamoto defined it as a “Peer-to-Peer Electronic Cash System.” Bitcoin was created as a digital form of money. It can be transferred from one user to another through a P2P network, which manages a distributed ledger called the blockchain. So, there are no banks processing or recording transactions in the Bitcoin network. Instead, the blockchain acts as a digital ledger that publicly records all activity. Peer-to-peer architecture can be developed and used in many different ways, and it is at the core of the blockchains that make cryptocurrencies possible. By distributing transaction ledgers across large networks of nodes, P2P architecture offers security, decentralization, and censorship resistance. In addition to their usefulness in blockchain technology, P2P systems can also serve other distributed computing applications, ranging from file-sharing networks to energy trading platforms.

The Evolution of Peer-to-Peer Technology — P2Plus (点对点技术的演进 — BitCherry P2Plus)

Bitcherry Technology Implementation — P2Plus Network Protocol

Network protocols are the foundation of network programs, andpeer-to-peer networks are also the foundation of the blockchain. Thus, BitCherry that security and communication speed of the network protocol to directly affect the safety and performance of the blockchain. From a technical perspective, the network is divided into 7 layers, also called the OSI seven-layer network model.

P2P protocols of current public chains are operating above the transport layer TCP host IPv4 / IPv6 WAN, BitCherry P2Plus work more underlying IP network layer and the data link layer (which can work simultaneously in Host and router), so P2Plus can easily penetrate any network, firewall, and network fence, greatly improving the accessibility of data transmission.

P2Plus Network Protocol Security

Different from the traditional P2P network protocol, in order to ensure the privacy of the network transmission and to prevent the gateway nodes from doing evil, the P2Plus network protocol implements point-to-point encryption. To put it simply, Bitcoin and Ethereum are transmitted in plain text during the network transmission process, and other network nodes passing through can be parsed.

the P2Plus network protocol uses a point-to-point private key encryption technology. The transmission content is encrypted and only the receiving node can decrypt it, ensuring the confidentiality of transmission content and node privacy. The public-private key mechanism can be used not only to encrypt the communication process but also to authorize access through signatures.

Because the underlying link layer and IP layer are transparent to the upper TCP application layer, a large number of traditional application layer services can be seamlessly migrated to the P2Plus network, thereby automatically implementing decentralized, point-to-point encrypted mail, chat, WEB service.
