Crypto Mining and Blockchain Networks: Powering the Future of AI
The convergence of crypto mining and artificial intelligence (AI) has emerged as a key area of innovation, blending two fields once seen as distinct. This intersection holds significant potential for reshaping AI development by addressing its growing demand for computational power and energy resources.
U.S. technology companies are increasingly pursuing energy assets held by Bitcoin miners as they scramble to secure a dwindling supply of electricity for their rapidly expanding AI and cloud computing data centers. These data centers are driving the fastest growth in U.S. power demand since the early 2000s, outpacing grid expansions and leaving tech giants like Amazon and Microsoft to compete for vast amounts of electricity.
As cryptocurrency miners look to redirect their surplus capacity toward AI, both sectors stand to benefit from this collaboration, with decentralized technologies offering new solutions to the financial, computational, and sustainability challenges facing AI. Analysts expect 20% of bitcoin miner power capacity to pivot to AI by the end of 2027.
The High Costs of AI Development
AI’s rapid advancements are driven by its reliance on vast amounts of computational power and energy, particularly for training complex models. These demands have led to the rise of massive data centers, which consume enormous amounts of electricity.
Building AI data center infrastructure can cost over $10 million per megawatt, whereas Bitcoin mining sites typically cost between $300,000 and $500,000 per megawatt, according to H.C. Wainwright’s Colonnese. Colin Harper, head of content and research at Bitcoin mining services firm Luxor Technologies, notes, “The market usually responds favorably to AI-related projects, but these builds are highly capital-intensive and require careful execution.”
Traditionally, the infrastructure to support AI has been dominated by a few Big Tech companies, resulting in centralized control and skyrocketing costs. For instance, OpenAI is projected to lose $5 billion this year alone due to the capital-intensive nature of AI development, while Meta has warned that expenses in AI research and development will continue to rise significantly.
As AI research and development accelerate, these costs continue to grow, prompting the search for innovative solutions to alleviate the financial burden.
Blockchain and Decentralized Computing Networks
Blockchain technology, known for its decentralized nature, has emerged as a potential solution to AI’s computational and cost challenges. Startups like Gensyn, Io.net, and Aethir are pioneering decentralized GPU marketplaces, where unused computing power can be rented out to AI developers. In 2023, Gensyn raised a $43 million Series A led by Andreessen Horowitz’s crypto-focused fund, while Io.net secured $30 million in March 2023 through a Series A led by Hack VC. Aethir has raised over $32 million and claims an annual recurring revenue of around $36 million.
Investors like Jake Brukhman, CEO and Founder at CoinFund, a crypto-native investment firm, suggest that the answer to soaring computing costs lies in a rental marketplace where individuals can auction off access to their unused local computing power. This approach enables users to train models and run queries in the cloud. In these blockchain networks, tokens are provided in exchange for GPU resources. This approach promises several benefits, including reduced costs, democratized access to AI resources, and enhanced data integrity through decentralized networks.
However, this innovative model is not without its critics. Some investors express skepticism about the effectiveness of decentralized solutions compared to centralized cloud providers. They argue that the performance and scalability of these decentralized networks may not match the capabilities of traditional data centers. Despite these concerns, the potential for blockchain to revolutionize AI development remains compelling, as it offers a path to reduce dependency on Big Tech and lower barriers to entry for smaller players in the AI field.
Bitcoin Mining: Energy Demands and Environmental Impact
Bitcoin has historically consumed a significant portion of the total energy used for crypto mining. Despite the technological advances in mining hardware, the environmental impact of Bitcoin mining remains a pressing issue. The extensive energy demands, waste generation, and water usage linked to crypto mining have raised significant environmental concerns. Bitcoin mining alone results in over 77 kilotons of electronic waste each year, as outdated hardware is discarded.
As of September 2024, the Cambridge Bitcoin Electricity Consumption Index suggests that Bitcoin alone uses around 150 Terawatt-hours (TWh) annually, representing about 0.6% of the world’s total electricity consumption. This figure surpasses the electricity usage of countries like Pakistan and Ukraine. Also, Bitcoin mining operates on more than 17 gigawatts of power demand. According to Digiconomist, Bitcoin mining is responsible for around 80 megatonnes of annual carbon emissions as of 2024.
On the other hand, Ethereum has a significantly smaller energy footprint, estimated at 0.01 TWh annually. Ethereum’s transition to proof-of-stake (PoS) in 2022 reduced its total power demand by at least 99.85%, and more cryptocurrencies are expected to follow suit, decreasing the overall energy footprint of the industry. Despite this, Bitcoin’s continued use of PoW and its major share of the sector’s energy consumption keep Bitcoin miners central in discussions about energy use in AI development. Balancing innovation with sustainability remains crucial.
The Bitcoin-AI Energy Exchange
While blockchain networks offer decentralized computing power, crypto mining introduces a complementary solution by addressing the energy demands of AI. Bitcoin mining, historically criticized for its high energy consumption, is now being repurposed to support AI operations. Miners, especially those in regions with abundant and affordable energy, such as Texas and North Dakota, are exploring partnerships with AI companies to supply surplus energy to data centers. For instance, Cloud computing provider CoreWeave recently signed a $3.5 billion deal with Core Scientific to use its data centers for AI computing hardware.
In an email to Unlock Blockchain, Olivier Ohnheiser, CEO of Green Data City, shared insights on this trend. Green Data City, which has secured the first license for sustainable crypto mining operations in Oman, is tendering and allocating 50 to 100 MW of extra capacity. The company is already considering redirecting surplus energy, as well as some of its mining capacity, to AI data centers. “As we move forward, some of the mining operations may become outdated while AI power requirements will rise significantly,” Olivier explained. This strategic move would allow Green Data City to diversify its portfolio while taking advantage of the rising demand for AI. “Higher profitability and diversification are key drivers, as demand from mining companies exceeds our capacity,” he added.
The symbiotic relationship between bitcoin miners and AI companies is mutually beneficial. Bitcoin miners can generate additional revenue by selling excess energy, while AI companies gain access to reliable and competitively priced energy sources. Statistics indicate that major Bitcoin miners could supply a significant portion of AI companies’ electrical energy needs. For example, 14 publicly listed U.S. Bitcoin mining companies currently control approximately 5 gigawatts of energy, and they could potentially provide around 3.6 gigawatts to high-performance computing (HPC) data centers, as per a JPMorgan report.
Research from Morgan Stanley shows that repurposing crypto mining facilities for AI and cloud computing could make them up to five times more valuable. Furthermore, buying or leasing space at a miner with at least 100 MW of capacity can cut the launch time for a data center by about 3.5 years, saving technology companies billions in operational costs. Building new data centers can take three to five years, with a waiting period of up to six years for power grid connections. This timeline underscores the immediate opportunity for Bitcoin miners to bridge the energy gap for AI.
This mutually beneficial dynamic is further emphasized by companies like Green Data City, which are strategically positioning themselves to capitalize on both sectors. Olivier told Unlock that their long-term vision involves balancing AI, crypto mining, and storage applications to create a sustainable computing hub. He highlights Oman’s unique advantages, including competitive energy prices, political stability, and direct connectivity to Indian Ocean internet cables, which make the country an attractive destination for AI investors. “This direct connectivity of deep ocean cables is a strategic advantage for AI companies in the region, in addition to the improved sustainability brought by the cooler temperatures and the Sea-water A/C (SWAC) benefits” Olivier explained.
Future Implications and Challenges
The future of AI development could be significantly influenced by decentralized approaches, though challenges like infrastructure upgrades, financial risks, and regulatory controls must be addressed. Environmental concerns are significant, with the IMF proposing higher electricity taxes due to the high carbon emissions from cryptocurrency mining and AI data centers. These sectors account for 2% of global electricity consumption and about 1% of global CO2 emissions. By 2027, these sectors are projected to use 3.5% of global electricity, with crypto mining potentially generating 0.7% of global CO2 emissions.
To mitigate these impacts, the IMF proposed a tax of $0.047 per kilowatt-hour for cryptocurrency miners, potentially rising to $0.089 with broader health impacts included, representing an 85% increase in electricity costs. For AI data centers, a tax of $0.032 per kilowatt-hour, or $0.052 with air pollution costs, is proposed. These taxes could generate $5.2 billion annually from crypto mining and up to $18 billion from AI data centers, potentially reducing annual carbon emissions by 100 million tons.
Despite these challenges, the potential for success in this space is substantial. A study by VanEck suggests that Bitcoin miners could achieve additional annual revenues of up to $14 billion by 2027 by expanding into the AI and high-performance computing sectors. This prospect highlights the importance of careful planning and effective risk management in leveraging the opportunities at the intersection of crypto and AI.
