What is Decentralized File Sharing?

Our world is increasingly moving towards decentralization, with traditional structures giving way to distributed and decentralized systems. One area that has long been moving towards this decentralization is file sharing, and numerous decentralized systems have emerged in this field. In this article, we intend to examine what decentralized file sharing is, how it works, and what its advantages and disadvantages are.

Today, many internet users rely on services like Google Drive, Dropbox, and OneDrive. However, these services have their drawbacks as they rely on central servers and are controlled by specific organizations. This raises concerns among users about their privacy and data security, and the cost of using these systems is relatively high. Therefore, decentralized file sharing systems have emerged as a solution to these problems, providing alternatives to traditional systems.

Decentralized file sharing involves sharing files across a distributed network rather than storing them on a central server. In these systems, data is stored in a network of interconnected nodes, utilizing peer-to-peer (P2P) technology. Each node or network user contributes their storage space and bandwidth to the network. In this way, there is no longer a need for central servers, and files are distributed among the network nodes. This type of sharing is considered more secure and stable compared to traditional file-sharing systems because files are distributed across the network. BitTorrent and InterPlanetary File System (IPFS) are two well-known protocols for decentralized file sharing, recognized among users of digital currencies.

Structure of Decentralized File Sharing Systems

Decentralized file-sharing systems operate based on peer-to-peer (P2P) networks, where users connect directly to each other. In addition to P2P networks, these systems also rely on blockchain and encryption technologies. Blockchain, by providing transparency and tamper-proof records, ensures the security of transactions and file transfers, thereby increasing user trust in decentralized file-sharing systems.

How Decentralized File Sharing Works

As previously mentioned, the foundation of decentralized file-sharing systems is a peer-to-peer network with a distributed structure that does not depend on a central server. Below, we explain the various functions of these systems and how each works.

Discovery of Peers in the Network

To enable users in a decentralized network to find each other, decentralized protocols and Distributed Hash Tables (DHT) are used. These two technologies, through different methods, enable communication and monitoring of peer activities. Distributed Hash Tables, as decentralized systems, are responsible for storing and retrieving key-value pairs distributed across the network. In contrast, decentralized protocols facilitate peer-to-peer interaction without the need for a central entity by establishing specific rules. In decentralized file-sharing systems, smart contracts can enhance efficiency by automating system operations based on predefined rules. Additionally, some decentralized systems utilize servers from well-known protocols such as Bit Torrent and IPFS.

Distribution of Files

In decentralized file-sharing systems, files are divided into smaller parts that are shared among network members. This method prevents files from being stored in a single location and makes access to them easier for network members.

Interaction of Network Members

Network members request shared files from each other and share these files directly. In this model, each network member acts as an independent client and server, thereby eliminating the need for central servers.

Blockchain Technology and Smart Contracts

Blockchain, with its high transparency and security features, transfers these qualities to decentralized file-sharing systems. The use of blockchain technology and encryption in these systems increases the security of shared files and protects users’ privacy.

Benefits of Decentralized File Sharing

In decentralized file-sharing systems, there is no risk of a single point of failure, making these systems more reliable and robust compared to traditional methods. Even if multiple nodes in the network are lost, the system continues to function.

Additionally, decentralized file sharing offers high levels of privacy and security. Only authorized individuals can access and decrypt the files, reducing the risk of unauthorized access and data breaches. As the number of network members increases, the network’s scalability also improves, allowing the system to handle larger volumes of data. These systems often use incentive mechanisms like tokens to encourage users to join the network.

Encryption technology also protects the confidentiality and integrity of shared data. If the system employs end-to-end encryption (E2E), users’ trust in the system increases since only authorized individuals have access to the content. Together, these technologies create a secure and decentralized system that facilitates easy file sharing in a distributed manner.

Challenges of Decentralized File Sharing

Although decentralized file-sharing systems offer numerous advantages, they also come with challenges. As the network grows and expands, scalability issues may arise, requiring better technology and more powerful bandwidth over time. Additionally, due to the lack of a central authority and controller, the system may face difficulties in synchronizing files. If different versions of files are not compatible, it can lead to conflicts in data structure.

Moreover, decentralized file-sharing systems typically have more complex user interfaces compared to traditional systems, making them somewhat difficult for individuals unfamiliar with blockchain technology and peer-to-peer networks. Another issue is the potential for security vulnerabilities. As the network grows, security measures need to become stronger and more effective. Furthermore, given the legal status of cryptocurrencies, the absence of formal regulations for decentralized systems can negatively impact their long-term acceptance and stability.

Future Outlook for Decentralized File Sharing Systems

In the future, decentralized file sharing systems are expected to create comprehensive, secure, and innovative environments for users. With the more prominent role of blockchain technology and distributed ledgers, the security and transparency of transactions will increase. It is likely that direct file transfers between network members will become possible, reducing network latency. As encryption techniques advance, privacy concerns will diminish, giving users greater control over their data. Additionally, new features and services like tokenization will incentivize users and create more harmony within the ecosystem


Unlike traditional systems that rely on centralized servers, files in decentralized file sharing systems are stored in a distributed manner. Utilizing encryption technologies and blockchain, these systems offer higher security and privacy. This article has discussed decentralized file sharing systems and how they function.
