Sia aims to offer a decentralized cloud storage infrastructure. Sia connects users who need file storage to a distributed global network of hosts, willing to offer under-utilized hard-drive capacity.
The Sia blockchain allows this marketplace to run without intermediaries. Sia secures the storage transactions with a set of smart contracts, creating a (supposedly) more reliable and affordable offering when compared to traditional cloud providers.
The Sia network runs on a Proof-of-Work (PoW) consensus algorithm.
The SC token is used to pay for storage services offered on the platform.
