A decentralized data sharing among users is other characteristic with the usage of peer-to peer or P2P, communication systems are free from centralized servers. However, current protocols of the P2P system present problems such as data ownership, access control, and privacy. To address this problem this article delineates a solution based on a blockchain approach toward rectifying these drawbacks through an encrypted P2P communication architecture. Smart contracts and decentralized ledger system also make sure safe data transfer and that the system is protected against alterations. The given system synthesis is suitable for application such as secure messaging and data sharing with the possibility of the design of scalable and robust system implementations. As for the research questions of this study, this research presents an effective P2P communication framework based on blockchain in order to achieve a more secure and private communication and trust in decentralized networks. By adopting the blockchain properties of Cryptographic Hashing and an immutable ledger, the systems record all data exchange transactions and makes them auditable. In addition, contracts managed by smart technologies within the blockchain enable trustless transactions between the users without the involvement of middlemen while honoring certain conditions.
