5G and Blockchain Technology: A Game-Changing Duo?

The cellphone industry is buzzing over the last few years over the subject matter on 5G wave. Deemed to be the ‘next big thing’ from the world of cellphones. The US is already planning in rolling out the next 5G networks from all the four major carriers of the country. The fifth-generation network promises for a booming speed, along with reduced latency, such as quicker time to respond as well as higher capacity i.e. a maximum number of devices can be handled. This comes with the added bonus of enhancement in security. Merge 5G with blockchain technology and you get a game-changing duo that could change the entire future of telecommunications and technology.

The dawn of innovation in augmented realities, artificial intelligence and blockchain have become a glimmering catch with the promising scope of innovation. The rise of blockchain technology from a niche community to mainstream is growing all thanks to the popularity of cryptocurrencies.

If you thought that the 4G revolution was great, imagine what would be 5G. The 5G network can transmit data over 10gb per second while compared to 4G’s data capacity over 100MB per second. Greater interconnection, lower latency, and faster internet, this is what 5G promises.

Experts say that that it can handle up to a download over 33 HD movies over less than half a second. Consequently, data-centric apps and downloads would be enhanced in a futuristic sense.

5G, IoT, and Blockchain: Is The Future Near?

The manifold combo of 5G, IoT and blockchain will birth out the rise of smart cities, driverless vehicles and smart homes. Perhaps the future is automation through IoT networks of smart devices containing sensors communicating over 5G.

IoT and 5G collectively have good potential but that may only be accomplished by utilizing blockchain technology. While 5G provides connectivity refuge for IoT apparatus and trades, blockchain manages security and guarantees the security of consumer and trade information. And this trinity would be quite powerful as every part strengthens another.

This whole thing could unlock another concept called the Internet of Skills (IoS). That would make it possible for the specialists to conduct their work remotely through VR headsets. For example, a dentist would even be able to perform his work remotely.

Can Someone Finally Solve Data Security?

5G, in fact, enhances blockchain technology by increasing node participation and decentralization all allowing shorter block times while driving on-chain scalability. The decentralized nature of blockchain means it is resistant to most of the safety problems. Its high-tech encryption provides increased security against hacking compared to the classic client-server system.

Decentralized blockchains offer benefits over the current client-server model used in IoT. The decentralized architecture means that identity could be protected and guaranteed.

Currently, IoT devices identify themselves via cloud servers, with their identification data being held in these databases. As such, the data could be compromised, stolen or imitated, while presenting major security threats to any application that runs on top of such network. By using a decentralized blockchain, you protect these identities through the use of asymmetric cryptography and secure hashing algorithms.

Devices would be registered according to their own corresponding blockchain addresses, guaranteeing their identity. This blockchain layer could provide a level of security and frictionless identification unmatched by the existing centralized infrastructure.

Moreover, blockchain smart contracts often depend on oracles. These oracles relay external data to the contract. While this information can only be transmitted with internet access for applications such as supply chains, 5G can facilitate these oracles in remote areas where otherwise would not be possible.


Although the union of 5G and IoT already promises to become a blissful one, there are still valid concerns particularly in the subjects of its privacy and security. The bottlenecks in security and capacity in IoT is what makes the technology from reaching its fullest potential.

Malicious devices could create chaos among the whole network due to interconnectivity. While the integration using blockchain might actually lead to slower processing of information and transactions.

That is an expected challenge of infusing 5G and IoT using blockchain. Maybe, the rate of 5G or even a superior mobile technology will balance this up slower processing.

Finishing Thoughts

To sum up, 5G, IoT and blockchain all impact one another to flourish in this world. There are still challenges on 5G and IoT today, therefore we have to expect that engineers and programmers finds a way to fix around the expected blockchain scalability problems so that the three technologies can attain their unified possible.
