What Is Decentralized Storage?
Decentralized storage is a system that utilizes decentralized networks to store and retrieve data.
It emerged in the early 2010s with projects like IPFS, Storj, and Siacoin.
The core concept is to leverage the benefits of decentralized networks to enhance privacy, security, censorship resistance, cost-effectiveness, and availability of file storage systems.
Decentralized storage should not be confused with traditional cloud storage, where files are stored remotely on servers controlled by a single service provider.
Advantages of Decentralized Storage
In cloud storage, data is centralized, meaning it relies on a single point of failure.
Downtime or security breaches can reduce the availability or loss of stored data.
Additionally, cloud storage is managed by a private entity, giving them control over access and the ability to censor data.
In contrast, decentralized storage systems divide user files into encrypted fragments and distribute them among multiple participants in a geographically and organizationally distributed network, often based on blockchain technology.
This approach offers several advantages:
- Increased security and privacy: By distributing encrypted fragments across multiple nodes, even if some nodes are compromised, the files can still be retrieved from the remaining nodes. This redundancy enhances security and privacy.
- Enhanced censorship resistance: Decentralized storage networks are not controlled by a single entity, making it difficult for any individual or group to censor or control the stored data.
- Improved uptime: Data can be retrieved from multiple network nodes, most of which are online at any given moment. This distributed nature of decentralized storage systems leads to improved availability and uptime.
Decentralized storage represents a promising alternative to centralized cloud storage, offering increased security, privacy, and resilience by leveraging the power of decentralized networks.
