SCC Mining
How traditional SiaClassic mining works
SiaClassic (SCC) is a 2018-era fork of Sia. It uses Blake2B (the original Sia hash), not the later Blake2B-Sia firmware used by current Siacoin ASICs. This page lists Obelisk SC1 variants, Innosilicon S11, StrongU STU-U2, and Antminer A3 under Blake2B / SiaClassic.
The SCC network hashrate is effectively idle and the coin price is not a functioning market. This page documents the algorithm and the remaining ASIC catalog. It is not a recommendation to buy SC1/A3 hardware for profit.
SiaClassic mining pools
Expect empty or historical pool listings. Verify a pool is actually finding SCC blocks before you waste power:
- MiningPoolStats: Search SiaClassic; many indexes have dropped the coin.
SiaClassic mining algorithm
Blake2B here is the original Sia PoW. Current Goldshell SC / iBeLink BM-S machines are sold for Blake2B-Sia (Siacoin). Do not assume an SC5 Pro will hash SCC without firmware that explicitly names SiaClassic/Blake2B.
The ASICs on this page are the old Obelisk/Innosilicon/Bitmain A3 generation. Several are dual-algorithm (for example Obelisk SC1 Dual lists Blake2B and Blake2B-Sia). Read the model page.

How to set up a SiaClassic mining rig
-
1. Confirm the network is alive
Check a block explorer and pool indexes for recent SCC blocks. If nothing is landing, mining is an electricity sink.
-
2. Use Blake2B-capable firmware
SC1 / A3 / S11 generation, or a dual-algo unit in Blake2B mode. Siacoin-only firmware is the wrong target.
-
3. Wallet
You need an SCC address, not an SC (Siacoin) address. If you cannot find a maintained SCC wallet, do not start.
-
4. Pool or solo
If no pool is finding blocks, solo against a node is the only option—and still useless without a live chain.
-
5. Measure once
If shares never confirm, stop. Do not leave 1 kW+ Blake2B hardware hashing a dead fork unattended.
Frequently asked questions
No. SCC is a fork. Different chain, different (older) Blake2B mining stack, different wallets.
Only if firmware and the pool both speak SiaClassic Blake2B. Those units are sold for Siacoin Blake2B-Sia. Default answer is no.
So the Blake2B ASIC catalog and the Siacoin catalog stay distinct. Hardware pages still need a coin article to link to.
No. Power cost dominates a network with ~zero hashrate and no meaningful price.
