The Antminer S9 is a Bitcoin mining machine, specifically designed for the SHA-256 algorithm. Ethereum, however, utilizes the Ethash algorithm.

Algorithm Incompatibility
Due to this fundamental difference in algorithms, an Antminer S9 cannot directly mine Ethereum. The hardware is optimized for SHA-256 computations, not Ethash. Attempting to do so would be highly inefficient and unprofitable.
Alternative Uses for Mining Rigs
Although an S9 can’t mine Ethereum, there are alternatives. One could explore mining other cryptocurrencies that utilize the SHA-256 algorithm or consider repurposing the hardware for other computational tasks.
Heat Generation and DIY Projects
The S9 generates significant heat, leading to projects like the DIY Bitcoin Space Heater using heat block kits. These kits repurpose the heat output for practical applications, even if the original mining purpose is no longer viable for certain cryptocurrencies.

The Shift to Proof-of-Stake (PoS)
Furthermore, it’s important to note that Ethereum transitioned from a Proof-of-Work (PoW) consensus mechanism, which relies on mining, to a Proof-of-Stake (PoS) system. This transition, often referred to as “The Merge,” has rendered traditional Ethereum mining obsolete. Even if the S9 could mine Ethash, it would no longer be applicable.
Ethereum Classic (ETC)
While the main Ethereum chain has moved to PoS, Ethereum Classic (ETC) remains a PoW blockchain. However, even for ETC, the Antminer S9 would still be unsuitable due to its SHA-256 algorithm. Mining ETC requires hardware designed for the Ethash algorithm, such as GPUs or specialized Ethash ASICs.
Investment in ETC Ecosystem
Mining pools and other entities continue to invest in the Ethereum Classic ecosystem, recognizing its continued relevance as a PoW chain. However, this investment is directed towards supporting infrastructure and development, not towards attempting to use SHA-256 miners on Ethash.
Final Verdict
To reiterate, the Antminer S9 is designed for SHA-256 mining and is not compatible with Ethereum or Ethereum Classic. The move to PoS for Ethereum further solidifies the obsolescence of mining hardware for the main Ethereum chain. Consider alternative cryptocurrencies compatible with SHA-256 or repurposing the hardware for other computational tasks or heat generation.
