Traditional storage solutions rely on expensive data redundancy, leading to high costs. Next-generation storage networks change this situation through mathematical sharding technology. The core idea is simple: break files into mathematical fragments, so even if some nodes go offline, the entire network maintains strong fault tolerance. As a result, storage costs are driven down to very low levels. From a technical perspective, this is a redefinition of resource allocation efficiency. From an economic perspective, it means that the availability and price competitiveness of Web3 infrastructure will see significant improvements. Such innovations are rewriting the cost equation of distributed storage.
