In Columns, Technology

The world is progressing and unfolding at a very fast pace, many technical inventions are taking place which has changed lives in drastic manners. Manual, repetitive and unvarying works have been replaced by machines which are indeed saving a lot of time from our busy days. Technology is capable of pushing, polishing and smartening our lives. With the new technology, there are also additions in the perils taking place. People are using illegal means to temper our valuable data. Many big organizations are facing tremendous loss due to these malpractices. Cyber attacks are taking place leading to disruption of data, breakdown of software and hardware and unauthorized access to our data. Cyber attack also leads to leakage of online data which helps the criminal to perform the fraudulent activities. Therefore there is a big demand to stop or have a regular check on these activities in the most reliable way possible.


A blockchain is an open, disseminated ledger that can record transactions between two parties efficiently, provably and permanently. A blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. This technology helps maintain security concerns and has fully taken attacks opposition to the next level.

DDoS Attack

We must have heard of DDoS attacks referring to distributed denial of service. These attacks are very destructive in nature. In this, the hackers use many algorithms to send the request and increase the traffic on the site till the point it is not able to receive further requests and the site crashes. The DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. The incoming traffic originates from different sources so that it makes it challenging for the management to stop the request by simply blocking the IP address of a single person. There are various types of DDoS attacks like the traffic attack, bandwidth attack, and the application attack.

Blockchain And DDoS Attack

The best help that blockchain technology provides in dealing with the DDoS attack is that it decentralizes the entire process, it distributes the contents to a large number of nodes thus making it impossible for the hacker to hack the data. Another benefit is that blockchain stores data on ledgers using encrypted blocks It removes the third party from making any alterations in the database thus making it more secure. Blockchain also includes private keys which allow the user to communicate with each other, it is stored on the system. Thus blockchain is a boon in controlling the devastating DDoS attacks.
