Siacoin SC
Storage payments and contracts.
Siacoin is the native coin of Sia, a network where storage providers and customers form blockchain-based storage agreements.
What is Siacoin?
Sia connects customers who need storage with independent hosts. File contracts lock Siacoin payments and host collateral, and storage proofs help determine the final payout. Siacoin is separate from Siafunds, another network asset.
Storage availability depends on contract terms, host performance, and the software or service used. Holding SC does not itself store or back up files, and hosts can lose collateral.

Sia’s mainnet launched in 2015. Its protocol and software have since changed, including the v2 upgrade, so older storage instructions may no longer apply.
