Comparison and Analysis of Decentralized Storage Platforms

Overview of Existing Solutions

Arweave

Arweave is a decentralized platform focused on permanent data storage. It employs a unique "Blockweave" structure that achieves high redundancy by distributing data copies across the network, allowing for indefinite data retention. Users pay storage fees using AR tokens. Arweave is particularly suitable for data that needs to be preserved long-term, such as archives, academic records, and more. However, it lacks file version control features.

BitTorrent

BitTorrent is known for its peer-to-peer ( P2P ) file sharing protocol, efficiently distributing large amounts of data over the internet. It has strong scalability and is widely adopted, making it particularly suitable for sharing popular files. However, BitTorrent lacks integrated blockchain technology and file version control features, which limits its practicality in some application scenarios. BitTorrent has also launched the BitTorrent File System ( BTFS ), aimed at providing storage services for decentralized applications.

Datum

Datum is an open-source decentralized data sharing protocol, primarily aimed at the scientific and academic fields. It supports secure versioned data storage and enables efficient sharing of large datasets through a P2P network. Datum emphasizes data privacy and user control, attracting communities that require data sovereignty. The platform is supported by developers and researchers dedicated to data sharing transparency.

Filecoin

Filecoin is a blockchain-based decentralized storage network that transforms cloud storage into an algorithmic market. It is built on top of IPFS, allowing users to rent out idle storage space and choose providers based on factors like price and redundancy. The blockchain foundation of Filecoin ensures transaction transparency and strong encryption, but does not support file version control. It is one of the most scalable solutions in the decentralized storage space, with an ecosystem that is continuously evolving.

Hypercore Protocol

The Hypercore protocol aims to achieve fast, scalable, and secure real-time data sharing. It is built on an additional log similar to a lightweight blockchain, supporting high redundancy and scalability, making it suitable for applications such as collaborative environments and real-time data streams. Hypercore's support for file version control enhances its practicality, especially in collaborative projects.

IPFS

InterPlanetary File System ( IPFS ) is a decentralized P2P file sharing network that uses a content-addressing scheme. This makes IPFS especially suitable for decentralized web hosting, distributed data sharing, and content distribution. IPFS supports file version control and has a large and active user community. Several decentralized storage solutions use IPFS as the underlying technology.

MaidSafe

MaidSafe operates on the Secure Access For Everyone (SAFE) network, which is a decentralized file system that prioritizes user privacy and data sovereignty. It supports file version control, ensuring data integrity and accessibility. MaidSafe uses Safecoin as its native cryptocurrency to facilitate secure transactions within the network. It is especially favored by users who value privacy and security, though its scalability is average.

Sia

Sia is a decentralized cloud storage platform based on blockchain that splits, encrypts, and distributes files across the network, providing high redundancy and security. Users can rent out unused storage space, forming a decentralized market. Sia uses strong encryption technology, has moderate scalability, and is a secure alternative to traditional cloud services. Transactions within the network use Siacoin tokens.

Storj

Storj is another decentralized cloud storage platform that utilizes blockchain technology, providing secure and cost-effective data storage. It encrypts and splits data into small pieces, distributing them across a global network. Storj supports file version control, is highly scalable, user-friendly, and suitable for web hosting, data archiving, and content distribution. Storj uses the STORJ token to incentivize storage providers and facilitate transactions.

Swarm

Swarm is a component of the Ethereum Web3 stack, providing distributed storage and content distribution services. It is integrated with the Ethereum network, utilizing smart contracts to enhance data management and distribution. Swarm uses BZZ tokens to support operations and incentivize participants. Although scalability is generally limited, Swarm plays an important role as a decentralized infrastructure in the Ethereum ecosystem.
