Does it mine XBT? BLAKE2b miner compatibility list
XBT is mined with BLAKE2b. In practice that means the same ASICs built for Siacoin (BLAKE2b-Sia) mine it on stock firmware, pointed at an XBT pool or your own DATUM Gateway. Bitcoin's SHA-256 machines can't, and most Kadena (Blake2s) machines can't either. Here's what we know, model by model.
How to read this
- Confirmed: sold or listed for XBT by vendors and confirmed by pools or miners.
- Should work: a Sia/BLAKE2b machine. Same algorithm, stock firmware. Check your firmware's algorithm setting.
- Reported: community reports, no confirmed hashrate posted yet. Don't buy on this alone.
- No / Unlikely: doesn't work, or no evidence it can.
| Model | Hash rate | XBT? | Notes | |
|---|---|---|---|---|
| iBeLink BM-S3+ | 25 TH | Confirmed | Most efficient BLAKE2b miner (about 0.14 J/GH). | Shop ↗ |
| iBeLink BM-S3 | 19 TH | Confirmed | Shop ↗ | |
| Goldshell SC5 Pro | 11 TH | Confirmed | Shop ↗ | |
| Goldshell SC Lite | 4.4 TH | Confirmed | Home-friendly at about 950 W. | Shop ↗ |
| Goldshell SC Box | 0.9 TH | Confirmed | Quiet, 200 W. | Shop ↗ |
| Goldshell HS5 | 2.7 TH (SC mode) | Confirmed | Set the algorithm to SC / BLAKE2b. | Shop ↗ |
| Goldshell SC5 Pro II | 14 TH | Should work | Sia miner, stock firmware. | Shop ↗ |
| Goldshell SC6 SE | 17 TH | Should work | Sia miner, stock firmware. | |
| Goldshell SC Box II | 1.9 TH | Should work | Sia miner, stock firmware. | |
| Goldshell HS-Box, HS-Box II, HS3, HS6, HS Lite | varies | Should work | Handshake/Sia dual machines. Use SC / BLAKE2b mode. | |
| iBeLink BM-S1 Max | 12 TH | Should work | Sia miner. | |
| Innosilicon S11 SiaMaster | 4.3 TH | Should work | Older Sia miner, about 0.32 J/GH. | |
| ePIC SC200 | 2.2 TH | Should work | Older Sia miner, about 0.59 J/GH. | |
| Obelisk SC1 | 0.55 TH | Should work | Old and inefficient (about 0.9 J/GH). | |
| Bitmain Antminer A3 | 0.8 TH | Should work | Runs on stock firmware, but at 1.56 J/GH it usually loses money. | |
| Goldshell KD5 Pro (580-chip version) | varies | Reported | One X account that trades miners says it switches to "blake2b (SC)" from a dropdown after the latest official firmware. Others dispute that source. Nobody has posted XBT hash rate from one yet. Treat as unverified. | |
| Goldshell KD5 | varies | Reported | One community test says it runs BLAKE2b. Unconfirmed. | |
| Goldshell KD5 Pro (9590-chip version) | No | Same label, different chips. Reported not to support BLAKE2b. | ||
| Goldshell KD Box Pro | No | 0 H/s on BLAKE2b in one community test (firmware 2.2.4). | ||
| Other Kadena miners: KD6, KD7, KD Max, KD Lite, KD Box, KD Box II, Bitmain KA3, iBeLink BM-K3 | Unlikely | Built for Blake2s, a different algorithm. No evidence any can mine BLAKE2b. | ||
| Any SHA-256 miner (Antminer S19, S21 and others) | No | Wrong algorithm. XBT has used BLAKE2b since block 961,640. |

The Kadena question
Kadena miners use Blake2s, a different hash from XBT's BLAKE2b. The chips are hardwired, so a firmware update can't change the algorithm unless the silicon already supports both. One X account that trades miners claims that Goldshell's KD5 Pro with the 580 chip shows a "blake2b (SC)" option after updating to the latest official firmware, while the KD5 Pro with the 9590 chip doesn't. Nobody has explained how to tell them apart before buying. That source has been disputed by other XBT users. Until someone independent posts real XBT hash rate from one, treat it as unverified, and be wary of anyone selling Kadena boxes as XBT miners.
Before you buy
- Run the numbers. Profit depends on price, difficulty and your power cost. Compare every miner at live difficulty.
- Ask the seller for a screenshot of the miner's dashboard hashing BLAKE2b, with a pool, before you pay for anything in the Reported or Unlikely rows.
- Point it at your own DATUM Gateway if you can. Knots 29.4.3's release notes say pool hashing without your own gateway may never get paid. Details
- New rewards are locked about 180 days from block 979,919. Plan cash flow around that.
