Importance of Blockchain in Cyber Security

April 19, 2022

As we are advancing towards a more digitized future, the chances of being sabotaged by technological backdrops are somewhat high. In this Crypto Genius, Blockchain, a decentralized network system, offers us various fields, which we did not even know of. The Crypto market and the NFTs, both incorporated under the Defi ecosystems, are the biggest examples of such matters. We only acknowledge the fact that how much we are gaining from this decentralized exchange system. However, other things are also improving under the supervision of this network system, and Cybersecurity is one of those.

IoT Security

The Internet of Things and its application for the development of technologies is always on the rise, and under such scenarios, the malicious attacks are increasing as well. It has always been an issue when it is about securing the data completely, and many networks, even after trying, failed miserably. Blockchain here comes with its unique systematics where the connection is only established on a device-to-device basis. The intermediates are always avoided, and each peer-to-peer connection is maintained by a single node. The information is always conserved by the network system, and anonymity is always maintained. IoT systems using the Blockchain for security concerns have improved a lot, and that is why this idea is being considered by many other IoT departments.

Integration in Downloads 

During many software updates, it has been identified on many occasions that many malicious updates enter the device and infect it. Whether it is used for data theft or if it causes the system to shut down completely, these occurrences quite often make the productivity flow come to a halt. In such cases, Blockchain can prevent attacks by detecting malicious software. The hashes are recorded in the blockchain system, and these are used to identify the differences. If the new software identity matches the data conserved in the hashes, it means the contents are harmless.

Reducing DDoS Attacks 

During the Bitcoin Era, DDoS attacks have gained a lot of traction, and we all are well associated with them. These cyber-attacks aim to flood the connection system with internet traffic to disrupt the services. With the frequent DDoS attacks, the network gets slow and faulty, resulting in a lack of data production and circulation. Blockchain here can be a big help with their encryption feature. The data, which circulates under a blockchain network, is encrypted, and any perpetrator trying to read or utilize the information for their gain always fails. In addition, the data present and created in a blockchain network are immutable.


It involves ensuring that only those who are willing and permitted have exposure to the necessary information. When passing across insecure channels, blockchain data is fully encrypted, ensuring that it is not available by unauthorized people. Safety features like accessibility restrictions must be applied immediately at the software interface to avoid intrusions from inside the system. By employing public-key encryption to verify participants and encrypting their interaction, Blockchain could enable extensive safety measures. Nevertheless, storing duplicates of private credentials in additional locations puts them in danger of being stolen. To avoid it, key administration processes like IETF or RFC should be established, as well as encryption algorithms focused on numerical multiplication issues.


Cyber attacks intended to disrupt the provision of technical support have increased in consecutive years, with DDoS threats becoming the most frequent. DDoS assaults against blockchain-based systems, on the other hand, are expensive since the perpetrator tries to overwhelm the system with a large number of little operations. Because blockchain technologies had little one source of breakdown, IP-based DDoS assaults are less likely to affect routine operations. Information is accessible at all periods via multiple nodes, allowing entire copies of the ledger to be accessed at all times. Platforms and systems are more resilient because of the integration of several nodes and distributed operation.

No Single Point Failures

As the whole system is decentralized, an individual node breakdown does not affect the whole system. Because many versions of ledgers are maintained, the network is not affected even under DDoS threats. Private Blockchains do not have such benefits.

Data Transfer

Verification is maintained throughout information exchanges via Blockchains Public Key Architecture. Throughout a transaction, smart agreements assist with the automated implementation of deals between two participants.

Most Blockchains utilities are indeed central to the digital business platforms, but they can help in many situations where Cybersecurity is constantly challenged and affected.
