What is P2P (Peer-to-Peer) Network?

At the center of decentralization lies Peer to Peer (P2P) networks, a protocol that allows us to interact directly with the other user(not through the centralized servers or intermediary). As a decentralized approach, P2P networks allow for sharing data, resources, transactions more efficiently and resiliently, making P2P networks a key technology for file sharing, communication, and the blockchain systems (such as cryptocurrencies). This chapter will deep dive into how P2P networks work, what impact it has brought to DApps, and the related challenges in current decentralized applications.

P2P (Peer-to-Peer) Network: Decentralizing Data Sharing and Transactions

One foundational technology in the world of decentralization is Peer to Peer (P2P) networks, where users share data and resources directly among themselves, without the aid of intermediaries. A P2P network consists of a group of individual participants (or nodes) that serve as both server and client, fostering the effortless transfer of files, services or even the conducting of transactions across the network. In part, this decentralized model is more agile, more scalable, it is more secured than a traditional centralized system. Many applications use P2P networks from file sharing and communications to blockchain based systems such as cryptocurrencies.

How P2P Networks Work

A P2P network is a network where each participant is directly connected to other participants, and consequently, there is no central server to mediate between its peers. Communication between nodes in the network and the exchange of data is directly performed and the workload is distributed among all participants. Using this model helps you share files or resources without a single point of failure. In terms of blockchain, the P2P ecosystem guarantees every node preserves a copy of the distributed ledger while authenticating and certifying the transactions amongst themselves. For instance, Bitcoin runs on a P2P network meaning that people can send and receive digital money among themselves, without intermediaries such as banks.

P2P Networks Pros and Cons

P2P networks have a lot to offer — they are decentralized, meaning they don't require a central authority, and so are very resilient to failures and censorship. P2P networks can grow efficiently because they scale well because new nodes adds resources to and increase the strength of the network. However, in many cases P2P networks are also more secure because data is spread across many nodes, decreasing data breach or single point of attack risk. P2P networks allow for faster, more clear cut transactions without the middle man when it comes to blockchain applications.

However, managing the data consistency and communication of nodes in the P2P network is an issue. If the network increases in its size, synchronization among nodes can get harder and so can the network performance. Also P2P networks may be more susceptible to the attack of malicious agents unless nodes are secured properly. Decentralized systems provide resilience; however, because the coordination of this resilience is happening over a large amount of participants, coordination itself gets complicated with decentralization.

Conclusion

P2P (Peer-to-Peer) network offers a powerful and decentralized way to share data, services and transactions. With the sharing of responsibilities among all participants, P2P networks foster more resilient, more scalable and more secure systems than the typical centralised model. They provide a great deal of decentralization and security benefits, however, these increase in difficulty to the point of managing coordination and performance as the network grows. With its development, blockchain and DAPPs will also continue to develop, P2P networks are indispensable along the digital highway, allowing peer to peer transactions and decentralized communication.
