Best Sia (SC) Miners — Blake2B-Sia ASICs
Sia (SC) is the proof-of-work currency that secures the Sia decentralized storage network — a Filecoin alternative that’s been operating since 2015. Mining uses Blake2B-Sia, a custom variant of the Blake2B hash function. The network is small but stable, with predictable economics.
What Sia does differently
Sia rents distributed storage from hosts who stake SC as collateral. Mining isn’t directly tied to storage capacity — it’s the standard PoW mechanism that secures the chain. But mining SC connects you to a network with a real underlying utility (cloud storage), which is a structural argument for long-term stability.
Why mine Sia
Lower-variance returns than newer speculative chains like Aleo. Smaller absolute revenue ceiling, but predictable. Good complement in a multi-coin mining portfolio for someone who wants exposure beyond Bitcoin without taking moonshot risk. See How to Choose Your First Miner for guidance on when alt-algo diversification makes sense.
Hardware in our catalog
Goldshell SC5 Pro (11 TH/s Blake2B-Sia, 600 W) — current-generation Goldshell unit. Best dollar-per-hash in the SC category.
The older Goldshell SC Lite (4 TH/s, lower power) remains available in some markets but the SC5 Pro’s efficiency advantage makes it the better choice for any new deployment.
