A patient with spinal cord injury completed a Bitcoin transaction on a computer using a chip implanted in the brain, using only thought, and the entire process took less than 3 seconds—this sounds like a scene from a sci-fi movie, but it may soon become a reality.
Neuralink, the brain-machine interface company founded by Tesla's Elon Musk, recently announced that they will begin 'mass production' of brain-machine interface devices in 2026. Currently, 7 subjects have undergone Neuralink's implantation surgery.
These subjects use the device for about 50 hours a week, peaking over 100 hours. Neuralink plans to implant in the speech cortex in the fourth quarter of 2025 to directly decode silent 'intent speech'.
01 Technological Leap
Elon Musk recently announced that his brain-computer interface company, Neuralink, will begin large-scale production of its devices in 2026. This declaration marks a critical turning point as brain-computer interface technology moves from the lab to the market.
Since completing the world's first human brain-computer interface implant trial at the end of 2023, Neuralink has implanted its 'mind-reading' chip into seven participants. These include four spinal cord injury patients and three ALS patients.
Current results show that participants can control computer cursors, draw, play games, and even operate robotic arms using only brain signals. These advancements are not only medical breakthroughs but also lay the foundation for deep integration between brain-computer interfaces and the digital world.
02 Development Blueprint
Neuralink has outlined a clear technical roadmap for the coming years, planning to gradually enhance the capabilities and complexity of its devices.
Q4 2025: Plan to implant in the speech cortex, aiming to directly decode silent 'intended speech'.
2026: The number of electrodes in implanted chips will increase to 3,000, and the first participant in the 'blind sight' project will join, helping the blind regain vision. Neuralink will begin large-scale production of brain-computer interface devices.
2027: The number of electrodes will further increase to 10,000, enabling multi-device implants, such as simultaneous implants in motor, speech, and visual cortices.
2028: The number of electrodes will exceed 25,000, enabling access to deeper brain regions for treating mental disorders, neuropathic pain, and beginning exploration of deep integration with AI.
Neuralink's ultimate goal is to build a 'full-brain interface,' enabling seamless interaction between the biological brain and external machines through high-bandwidth connections. Musk himself has stated that this technology is key to ensuring humanity's future in the age of artificial intelligence.
03 Market Potential
With the rapid development of brain-computer interface technology, its market size is experiencing explosive growth. 2025 is considered the 'year zero' for the brain-computer interface industry.
Data shows that the global brain-computer interface market has grown from $1.2 billion in 2019 to $1.98 billion in 2023, with an expected value of $2.48 billion in 2024.
More importantly, according to forecasts by the Prospect Industry Research Institute, the global brain-computer interface market will grow at a compound annual growth rate of 25.22% from 2025 to 2029, reaching $7.63 billion by 2029.
In the healthcare sector, the potential market size for brain-computer interfaces is astonishing. According to McKinsey's estimates, the global potential market for serious medical applications of brain-computer interfaces ranges from $15 billion to $85 billion, while the potential market for consumer healthcare applications ranges from $25 billion to $60 billion.
04 Interaction Revolution
When the brain can directly interact with the digital world, the way we hold and use cryptocurrencies will undergo a fundamental transformation. Imagine verifying transactions with thoughts, turning thoughts directly into private keys, or using brainwave patterns for identity verification.
Currently, cryptocurrency transactions still rely on traditional input devices—keyboards, mice, or touchscreens. This process is not only inefficient but also vulnerable to hacking. Brain-computer interfaces could completely transform this, enabling truly seamless transaction experiences.
For brain-computer interface users, they can control computers using brain signals to perform daily tasks such as typing, drawing, and web browsing. This means they might also use their thoughts to transfer and trade cryptocurrencies.
An anonymous neuroscientist warned: 'Although Neuralink's technological progress is impressive, our understanding of how the brain works—especially regarding higher-level cognitive functions—is still insufficient.'
05 Security Risks
As brain-computer interface technology advances, personal privacy protection has become a critical issue. Given the high sensitivity of EEG data, any leakage could lead to serious consequences.
If people's thoughts could be directly converted into digital signals, how can we ensure these signals are not misused? This involves not only technical safeguards but also legal frameworks and the protection of personal rights.
Research from Nanjing University of Information Science and Technology indicates that big data can analyze privacy information with greater precision, not only pushing information, videos, and products to users almost perfectly through electronic devices, but also potentially interfering with people's behavior via brain-computer interfaces.
For cryptocurrency users, this privacy risk is particularly severe. Brainwave patterns may become a new form of identity identifier, and if these data are stolen, users' entire digital assets would be at risk.
06 Philosophical Challenges
Brain-computer interface technology brings not only technical innovation but also a series of philosophical questions. Could this technology affect individual identity?
When a person's thoughts can be enhanced or even altered through technology, does that mean the individual's identity has changed?
In the cryptocurrency world, decentralization and personal sovereignty are core values. The introduction of brain-computer interfaces may redefine the boundaries and autonomy of 'individuals' in the digital world.
Research from the Department of Philosophy at Peking University points out that brain-computer interface technology raises ethical issues including security and effectiveness, personal identity and authenticity, brain privacy protection, decision-making autonomy, and responsibility attribution—issues that become especially complex in the context of cryptocurrencies.
The National Science and Technology Ministry's 'Ethical Guidelines for Brain-Computer Interface Research' states that research involving intervention in human thought, mental processes, and neural activities should be strictly controlled.
07 Integration Prospects
Despite numerous challenges, the integration of brain-computer interfaces and cryptocurrencies holds tremendous potential. Both technologies represent challenges to traditional centralized systems and a pursuit of individual empowerment.
Since 2025, China has also made frequent breakthroughs in brain-computer interface technology and clinical trials. According to a report by CCTV News in June, the Chinese Academy of Sciences' Center for Excellence in Brain Science and Intelligent Technology successfully conducted China's first prospective clinical trial using invasive brain-computer interfaces.
In July 2025, the MIIT and six other departments jointly released the 'Opinions on Promoting Innovation and Development of the Brain-Computer Interface Industry,' proposing that breakthroughs in key brain-computer interface technologies will be achieved by 2027.
Globally, the United States has established absolute leadership with 5–10 companies such as Neuralink and Synchron. Governments, research institutions, and enterprises in the EU, Japan, South Korea, Australia, and other countries have also accelerated their investments in brain-computer interface technology.
Alex, a spinal cord injury patient, has already been able to use his thoughts to operate CAD software and design parts. His future plans are even more remarkable: connecting to Tesla's humanoid robot Optimus' robotic hand for more complex operations.
Perhaps in the near future, robots controlled by brain-computer interfaces will work in Bitcoin mining farms, while their owners manage these assets simply by thought. When brainwaves become the new private key and thoughts turn into new transaction commands, the boundary between humans and the digital world will vanish completely.#马斯克概念 #BTC #加密市场观察
