While Blockchain technology has been around since 2008, many, including myself until recently, viewed it merely as a trendy name without much understanding of its implications. However, the reality is that Blockchain is increasingly woven into the fabric of our daily lives, potentially having a greater immediate impact than Artificial Intelligence. This lack of awareness may stem from its discreet operation, quietly working to secure our data amid growing concerns about data protection, particularly with regulations like GDPR coming into play. Now may be the perfect time to take a closer look at this remarkable technology.
Blockchain works by allowing data to be documented and maintained in a transparent, public ledger. Each unit of information, known as a “block,” is cryptographically linked to others, ensuring the system is resistant to tampering. The only way for a hacker to breach the system would be to simultaneously attack every computer or storage device within the Blockchain that holds identical information—an incredibly difficult feat, especially with potentially hundreds or thousands of connected machines. For a visual summary, here is a brief five-minute video on Blockchain:

Currently, Blockchain is utilized in numerous fields, particularly in financial services, where it facilitates near-instant asset transfers and enhances data security. Many people may not realize that without Blockchain technology, the well-known cryptocurrency Bitcoin would not exist; it serves as the foundation for Bitcoin and other digital currencies, similar to how the Internet underpins email. Beyond financial applications, Blockchain offers a myriad of possibilities for secure data storage and sharing.
For instance, the United Nations is leveraging Ethereum’s extensive Blockchain to ensure that aid funds directly reach those in need, a project that is expected to improve the lives of over half a million individuals. One of the most appealing aspects of Blockchain is its potential to eliminate government corruption. The technology is also making strides in the food industry by tracing contamination in the supply chain from farm to table. Additionally, the diamond industry utilizes Blockchain to verify ownership and authenticity, while the fishing industry employs it to confirm when and where fish were caught. The applications for Blockchain are vast, extending to public services, law enforcement, security, agriculture, education, insurance, immigration, real estate, governmental agreements, and even transportation, particularly in the realm of autonomous vehicles.
For example, Toyota plans to use Blockchain to gather driving data to support the development of self-driving cars. This technology enables the aggregation of billions of driving miles contributed by vehicle owners, fleet managers, and manufacturers, significantly accelerating the development of autonomous driving technology and delivering benefits to consumers more swiftly. Drivers will retain full control over their data, potentially leading to lower insurance premiums. By storing sensor data in a Blockchain, drivers can choose whether to share detailed insights about their driving habits with their insurers.
Toyota’s approach to Blockchain exemplifies just one of many paths this technology could take beyond finance and cryptocurrency. With its security features, speed, and autonomy, Blockchain has the potential to transform virtually every aspect of life we can imagine. Its simplicity, combined with its incredible capabilities, often makes it hard to grasp its full potential.
It’s also important to consider the significant role Blockchain could play in Bitcoin itself. Many believe that cryptocurrencies will become essential in managing the myriad microtransactions involved in daily travel, such as for road tolls, self-parking, Wi-Fi access, roadside communications, navigation data, V2I charges, telemetry, and more. This includes payments for fuel, electric vehicle charging, service needs, and other drive-thru services. Furthermore, there will likely be new MaaS (Mobility as a Service) transactions for public transport such as bus and train fares, scooter rentals, and bicycle hires, along with countless other emerging services requiring microtransactions.

Blockchain is undeniably a current event, not a mere speculation about the future. While the technology will continue to evolve, the news will likely focus on the exciting new applications that will emerge.
Although it’s not a competition, I find Blockchain to be a far more engaging technology, with a higher level of trust compared to the uncertain future of Artificial Intelligence.
