Siacoin (SC) is the native token of the Sia network, a decentralized storage platform facilitating global disk storage contributions to create a secure and private alternative to centralized cloud storage. Users can rent storage from hosts using Siacoin, with transactions managed by smart storage contracts on the Sia blockchain. These contracts ensure that hosts are paid only after securely storing a client's file for a specified duration, incentivizing reliable storage. The concept for Sia and Siacoin was conceived by David Vorick and Luke Champine, founders of Skynet Labs, at an MIT hackathon in 2013. Skynet Labs, formerly Nebulous, continues to evolve the platform, aiming to build a decentralized internet through its application hosting and storage.
