Wireless networks are a prominent technology that is nearly universally utilized. The benefits of easy installation, flexibility, increased extensibility, and wireless communication has made the technology an everyday part of life. From information to computing management, it is employed in different environments, including hospitals, universities, and airports. Even handheld gadgets like smartphones employ wireless connections to provide users with easy access to the internet. 

However, with rapidly expanding telecommunications infrastructures, existing wireless networks have become more complex and ubiquitous. The emerging 6G network, particularly, is facing new security threats and challenges with the current wireless technology. Even trust-related issues in network design are posing challenges in moving forward with 6G. One technology, however, promises to solve all the existing challenges.

Blockchain is the solution that aims to fix the challenges associated with wireless communication. It is the new paradigm in the making that can power networks of networks. 

Rising Challenges in Building the Sixth-Generation Network

The global rollout of 5G technology has been a success. However, the deployment of a 6G network is fraught with problems. Scalability is a major roadblock for its implementation since network customization at peak traffic is both expensive and technologically demanding. The second issue is a lack of low-latency connectivity for real-time communication.

Similarly, 6G cannot be easily integrated with industry applications since the technology lacks a coordinated integration system. Even the absence of increased out due to technical complexities is a concern for 6G. Data confidentiality is another drawback, as there are no standard validation and entry restriction measures in place to prevent unauthorized alterations. Even low-power encryption algorithms used in IoT devices are vulnerable and can leak data if compromised.

Additionally, a sophisticated 6G network would include a large number of interconnected devices, raising the possibility of a Distributed Denial of Service (DDoS) attack. Beyond that, it is necessary to evaluate, identify, and report on network system participants’ activity; however, screening a huge number of them and establishing a uniform device security would be challenging.

Tackling the Challenges with Blockchain Solutions

The difficulties with the 6G implementation appear to be overwhelming. However, blockchain’s features like decentralization, transparency, anonymity, immutability, traceability, and resilience promises to solve most of them. It can ensure the integrity of remote data and reduce computing power, ensuring smooth working of servers and consumer devices. It can improve the data security and prevent tampering with lease records.

Furthermore, blockchain can establish trust between data transferring channels when high-volume data is processed on consumer devices. It can also secure institution level confidence when exchanging energy or resources via smart devices or energy trading exchanges. Additionally, the technology can aid in the elimination of intermediaries, removing additional cost. Moreover, it can enable wide network connectivity and reduce scalability constraints.

Blockchain can also improve wireless communication by enhancing security and anonymity. While its adoption in IoT is still awaiting, research is being carried out to implement blockchain solutions. In fact, a few startups like TokLok are contributing to the 6G revolution. TokLok is a blockchain-based messaging app that provides a secure wireless communication service. It offers encrypted messaging service with the guarantee of anonymity. The platform is powered by the platform’s cryptocurrency $TOL, which also acts as the app’s core element.

The Sky is the Limit for Blockchain Applications

Technologies are evolving at a rapid speed. Wireless communication is also expanding into new generations, the most recent of which is 6G. While there is still time for this technology to materialize, infrastructural development is currently underway. The debate has begun on how to successfully deploy this technology, as there are several roadblocks in the way.

As a remedy to the roadblocks, blockchain technology is being advocated. Its integration in 6G would promote transparency and information exchange, supporting a variety of industries. The technology is capable of bringing 6G to market in a few years. With efforts like TokLok laying the groundwork, the path to 6G appears to be close at hand. 

However, extensive research and testing are being conducted to effectively implement the most anticipated technology to reality. It’s a matter of time and technical efficiency, and the world may soon see the next generation internet.
