Decentralized storage projects use blockchain to offer secure, censorship-resistant, and cost-effective data storage. Some focus on distributed file storage, like Filecoin, rewarding users for sharing excess storage space. Others, such as Arweave, provide permanent data storage, ensuring long-term accessibility. Redundancy, encryption, and scalability define their reliability. Here, we break down top decentralized storage projects with deep reviews, expert analyses, and insights into their impact on data security and accessibility.
