Summary

Unlike traditional centralized storage servers operated by a single entity or organization, decentralized storage systems store data files on geographically distributed nodes connected through a peer-to-peer (C2C) network.

Using blockchain to maintain a decentralized storage network ensures that data files are protected from errors, counterparty risks, and single points of failure, helping to improve storage security.

Introduction

In 2006, British mathematician Clive Humby coined the phrase “data is the oil of the new era.” In an age where our personal data and online experiences are deeply intertwined, this statement is more relevant than ever.

Today, private data, which is an integral part of our digital identity, is often stored in a centralized manner. Although centralized storage solutions are more accessible, users do not have full control over the data they want to share and how they want to share it, and may be more vulnerable to risks such as data loss, privacy breaches, and cyber attacks.

However, the advent of Web3 has changed the way we interact online, and blockchain technology has played a major role in this transformation.

Apps powered by blockchain can run independently without the involvement of a trusted third party, creating a decentralized Internet where users have more control over their data and online experience. In addition, with the advent of decentralized storage, users can access and store their data in a distributed manner instead of using a single centralized server.

Centralized storage vs decentralized storage

Centralized Storage

For many years, centralized data storage has been the only available storage solution, which involves keeping data on one or a group of servers, usually located in one place and managed by a single vendor.

In this way, data is easy to access and manage. For example, cloud storage is usually a centralized solution that stores data on servers maintained by a single organization (such as Amazon, Google, or Dropbox, etc.).

To ensure the security of centralized data storage, 128-bit SSL technology is usually used to encrypt data when it is transmitted from your computer to the centralized storage server. After the data is transmitted to the centralized storage server, 256-bit encryption can also be used to encrypt it.

Decentralized Storage

However, centralized data storage also has limitations. For one thing, no matter how stringent the security measures are, the encryption keys are held by the storage platform, which raises potential concerns about accessibility, transparency, and control. In addition, because all data is stored in one place, hackers can easily attack single points of failure in an attempt to steal large amounts of data.

Decentralized systems, on the other hand, store data on a geographically dispersed network of computers rather than in a single location. This allows large amounts of data to be stored without relying on a central server or provider, thus avoiding potential censorship and privacy issues.

How does decentralized storage work?

Decentralized storage involves storing data on multiple computers or nodes connected to a C2C network such as BitTorrent or the InterPlanetary File System (IPFS) protocol.

Data uploaded to a decentralized storage system is split into small pieces and then sent to multiple nodes on the corresponding network for storage. If you need to retrieve your data file, the network will piece together the shard components from the various nodes storing the file and then reassemble it for you to download.

In addition, nodes in the decentralized storage system cannot view or change files because the cryptographic hashing mechanism automatically encrypts all data stored on the network. Users must use their personal private keys to access their data and prevent unauthorized entities from retrieving relevant data information.

Advantages of decentralized storage over centralized storage

Decentralized data storage can alleviate some of the problems faced by traditional centralized storage servers. Compared with centralized storage networks, decentralized storage networks have several advantages as follows:

Higher data security and privacy

For traditional centralized storage networks, since all data is stored in one place, it is more vulnerable to network attacks. In contrast, for decentralized storage systems, since data is stored in multiple nodes rather than a single server, it is more secure.

This makes it more difficult for hackers to break into the decentralized storage network and steal information. In addition, users do not need to submit personal information to store data in a decentralized system, so they can enjoy the additional protection of anonymity.

No single point of failure

Although centralized data storage networks are easier to access and manage, they are also more prone to transmission errors, which may lead to data loss. Decentralized storage networks are composed of multiple connected nodes, with higher redundancy and fault tolerance, so even if a node fails, users can still access data through other nodes on the network.

Faster data download speed

If the traffic exceeds the network processing capacity, centralized storage may encounter bottlenecks. Decentralized storage relies on blockchain technology to distribute the storage nodes of data files around the world, thus potentially reducing bandwidth usage.

Lower costs

Since decentralized storage systems have many nodes hosting data, they have larger storage space than centralized storage systems. As a result, decentralized storage platforms are often cheaper, especially for small users who cannot benefit from economies of scale.

Higher data integrity

Data integrity refers to the ability of data to maintain the same quality throughout its lifecycle. Maintaining data integrity is challenging for centralized storage systems because once a server fails or a web page is migrated to another address, the stored data will become unavailable. In contrast, decentralized storage allows users to access data indefinitely and maintains data integrity through hashing.

What are the limitations of decentralized storage?

Although decentralized data storage has advantages over centralized systems, it also has some limitations that may conflict with the above advantages. For example, since decentralized storage systems rely on a network of nodes to store and retrieve data, access speeds may be slower than centralized storage systems.

From the perspective of data ownership, although decentralized storage systems may be more secure than centralized storage systems, they are also unable to avoid security risks and other risks, such as malicious nodes that may undermine the security of data stored on the network. In addition, decentralized storage systems rely on network infrastructure to operate properly. Therefore, if the network is interrupted, the availability of data stored on the network may be affected.

At the same time, decentralized storage currently lacks standardization. Different protocols may use different encryption methods and authentication mechanisms, making it difficult to ensure interoperability. In addition, the risks associated with the encryption process and key management in decentralized storage systems remain to be addressed.

Conclusion

Although decentralized storage is still an emerging technology and has yet to be widely adopted, it is expected to drive the development of the Web3 revolution. As users seek a more economical, efficient and secure data storage mechanism, the popularity of decentralized platforms such as BitTorrent may be faster than expected.

In addition, the prevalence of data breaches, rising storage costs, and censorship in the traditional data storage field may cause more users to turn to decentralized storage products. However, while decentralized storage may help solve some of the problems of centralized storage, it still has certain limitations. At present, centralized storage is still an attractive solution for many users, and even if decentralized storage becomes more popular, centralized storage will still occupy a considerable market share.
