Blake2B-Sia Mining: ASIC Miners for SiaCoin and Bitcoin Blake2B

Introduction

The Blake2B-Sia algorithm has been making a major comeback in the ASIC mining world lately. Because it powers both SiaCoin (SC) and Bitcoin Blake2B (BTCB2), the mining landscape around these machines is highly dynamic—things can flip fast the moment network conditions, coin prices, or difficulty levels change.

When profitability surged in late 2026, some of these rigs were pulling in serious revenue, briefly hitting or even crossing the $200-a-day mark. However, these conditions have already started to change, highlighting an important characteristic of this market: unusually high mining returns can disappear quickly as more hash rate enters the network or coin prices move.

For that reason, the following machines should be viewed primarily as Blake2B-Sia ASIC hardware options, while profitability and return on investment should always be recalculated using current market data and electricity costs.

Final Note

Blake2B-Sia mining demonstrates how quickly ASIC mining economics can change. A sudden increase in the value or demand surrounding the coins supported by an algorithm can temporarily transform older or previously less attractive hardware into profitable machines.

However, miners should not assume that the recent profitability spike will continue. SiaCoin and Bitcoin Blake2B mining returns depend on coin prices, network difficulty, total network hashrate, pool fees, and electricity costs. Anyone considering one of these ASICs should therefore calculate profitability using live data immediately before purchasing or deploying the machine.
