Sia
Sia is a decentralized cloud storage platform that leverages blockchain technology to create a peer-to-peer network for renting and providing storage space. It enables users to store data securely and redundantly across a global network of hosts, with encryption and smart contracts ensuring privacy and reliability. The platform uses its native cryptocurrency, Siacoin, to facilitate payments and incentivize participation in the network.
Developers should learn Sia when building applications that require secure, cost-effective, and decentralized storage solutions, such as for backup systems, content distribution, or data-intensive projects where traditional cloud storage may be too expensive or centralized. It is particularly useful in scenarios where data privacy, censorship resistance, and redundancy are critical, as it distributes data across multiple independent hosts globally.
