The rise of cryptocurrencies has given birth to a rapidly evolving mining industry, transforming from hobbyist experiments into a multi-billion-dollar global business. Behind every mined Bitcoin or Ethereum block lies powerful hardware designed to solve complex algorithms and secure decentralized networks. As the market matures, so too do the technologies and companies driving this digital gold rush.
According to Frost & Sullivan, global blockchain hardware revenue surged from just 70 million RMB in 2012 to 19.3 billion RMB by 2017 — a compound annual growth rate exceeding 200%. This explosive growth has been fueled by continuous advancements in mining technology, shifting from CPU-based systems to more efficient FPGA, GPU, and now dominant ASIC machines. Alongside these developments, new models like CDN and IPFS mining have emerged, redefining what it means to "mine" in the digital age.
The Dominant Force: ASIC Miners
ASIC (Application-Specific Integrated Circuit) miners are purpose-built machines designed for one task: executing a specific cryptographic algorithm with maximum efficiency. Unlike general-purpose GPUs, ASICs offer significantly higher hash rates while consuming less power per unit of work — making them the go-to choice for serious miners.
Today, over 90% of the ASIC mining market is controlled by three major players: Bitmain, Canaan Creative, and Ebang Communications. Among them, Bitmain leads with a dominant market share, reporting $2.5 billion in revenue in 2017 alone. Canaan and Ebang followed with $190 million and $144 million respectively.
These companies have set the standard for performance, reliability, and scalability in large-scale mining operations. Their flagship models continue to push the boundaries of energy efficiency and computational power.

Emerging Competitors in the ASIC Space
While the "Big Three" dominate headlines, several other manufacturers are carving out competitive niches through innovation and specialization.
Bitmicro (Shenzhen Bitmicro Electronics)
Founded in 2016, Bitmicro focuses on developing custom chips for blockchain and AI applications. Its founder, Yang Zuoxing, previously contributed to the design of Bitmain’s S7, S9, and L3 mining chips — bringing deep technical expertise to his own venture.
The company's flagship product line, "Shenma" (God Horse) miners, emphasizes energy efficiency. The Shenma M10, released in September 2018, uses a 16nm chip and offers two modes:
- Normal mode: 33.6 TH/s at 64.2 W/T
- Low-power mode: 26.7 TH/s at 59.6 W/T
This balance of performance and efficiency makes it competitive against similar-generation hardware.
Innosilicon (CoreOn)
Headquartered in Suzhou Industrial Park and Wuhan East Lake High-Tech Zone, Innosilicon was among the first to produce 28nm mining chips. Known for high-hash-rate devices, their T2 Turbo dual-rig miner can reach up to 48 TH/s, making it a favorite during peak demand periods.
Beyond Bitcoin mining, Innosilicon offers specialized hardware for various altcoins:
- A10: For Ethereum (ETH)
- S11: For Siacoin (SC)
- D11: For Decred (DCR)
- A9: For Zcash (ZEC)
Their diversified portfolio allows miners to adapt quickly to changing market conditions and coin profitability.
Bitfly (Higgs Supercube Group)
Established in 2017 and based in Shenzhen, Bitfly develops miners under the "Leopard" series. The Leopard A1, co-produced with Bitfury, delivers an impressive 49 TH/s hash rate for Bitcoin mining. They also offer the Leopard E3 for Ethereum, showcasing their expansion into multi-chain support.
Baikal
Founded in 2008, Baikal entered the crypto space in 2016 with its first miner, the Baikal Mini X11. What sets Baikal apart is its support for dual-algorithm mining, enabling users to mine multiple privacy-focused coins such as Monero (XMR), Electroneum (ETN), Bytecoin (BCN), and others simultaneously.
This flexibility appeals to small-scale miners looking to diversify earnings without investing in multiple dedicated rigs.
The Rise of Alternative Mining Models
While ASICs dominate proof-of-work (PoW) networks like Bitcoin, new paradigms are emerging that leverage underutilized resources — such as bandwidth and storage — to participate in decentralized ecosystems.
CDN-Based Mining
CDN stands for Content Delivery Network, a system that distributes content across geographically dispersed servers to improve loading speeds. In CDN mining, users contribute their idle CPU, bandwidth, and storage to accelerate web content delivery in exchange for tokens.
Key advantages:
- Low entry barrier
- Minimal maintenance
- Uses existing consumer hardware
Notable projects include:
- ThunderChain Token (LinkToken)
- BlockCDN
- TrafficCoin
- Baidu’s Baidu Coin
These platforms turn everyday internet usage into passive income opportunities — though returns remain modest compared to traditional mining.
IPFS and Decentralized Storage Mining
IPFS (InterPlanetary File System) aims to replace HTTP with a peer-to-peer hypermedia protocol that enables permanent, distributed file storage. Miners contribute hard drive space to store data across the network and earn Filecoin (FIL) as rewards.
Unlike ASIC mining, which requires expensive specialized hardware, IPFS mining relies on high-capacity storage drives and stable internet connections. However, it's important to note:
As of now, IPFS mainnet launched in late 2020 — meaning pre-launch "IPFS miners" sold before that date could not actually mine FIL. Many early devices were repurposed for other storage-based coins like Sia (SC), Storj, or Burst — often yielding low returns.
Current IPFS hardware providers include Maya Nodes, Mammoth Storage, Interstellar Nodes, and Interstellar Bit — though quality varies widely among smaller vendors.

Industry Outlook: Challenges and Evolution
Market Downturn and Consolidation
After the 2017–2018 bull run, the mining industry faced a significant correction. Demand for mining hardware dropped as coin prices fell and network difficulty rose. TSMC, Bitmain’s primary chip supplier, reported declining expectations due to “continued weakness in the cryptocurrency mining market.”
Regulatory tightening in key markets like China and the U.S. added further pressure. As profitability margins shrink, only well-capitalized players with access to cheap electricity and cutting-edge chips can survive.
The Race for Efficiency: 7nm and Beyond
Since mining profitability hinges on hash rate per watt, chip efficiency is paramount. The industry has moved from 28nm to 16nm processes — and now into 7nm territory.
- Canaan Creative integrated 7nm chips into its A9 series.
- Bitmain unveiled its own 7nm chip in late 2018.
Smaller process nodes mean more transistors per area, leading to faster computations and lower energy consumption — critical advantages in an increasingly competitive landscape.
Strategic Shift: From Mining to AI
With over 80% of Bitcoin’s total supply already mined (17.3 million out of 21 million), long-term sustainability is a growing concern for mining hardware firms. Recognizing this, top manufacturers are pivoting toward artificial intelligence and edge computing:
- Canaan Creative: Began mass-producing AI edge computing chips in Q4 2018.
