Blockchain technology will change the rules of the cybersecurity game

Cybersecurity experts believe that blockchain, the core technology behind Bitcoin, will become a powerful weapon to combat cyber attacks.

Blockchain technology features

Blockchain is a database responsible for recording and storing all Bitcoin transaction information. The difference between it and a regular database is that blockchain does not exist in a centralized form, but is updated and maintained by a user network. This can be understood as a multi-user shared, updated and maintained document or spreadsheet similar to Baidu Netdisk. Blockchain also follows a similar processing idea.

One of the key features of blockchain technology is the use of a distributed database. In a distributed database, there is no centralized control mechanism for network resources. Unlike traditional client/server networks that centralize all data in one location, blockchain is a large peer-to-peer (P2P) network in which each participant needs to update a document or ledger.

As shared information, data is constantly updated between multiple computers on the Internet. The reason why it is favored by cybersecurity experts is that there is no centralized network such as a server. Blockchain technology eliminates a single storage location that may lead to data leakage.

Satoshi Nakamoto, the creator of Bitcoin, realized that in order for Bitcoin to be truly used as a currency, the same person must not be allowed to spend the same Bitcoin twice. To achieve this goal, Bitcoin also requires a distribution system without a third party (such as a bank), thus establishing an unconventional payment system.

Advantages of blockchain

Blockchain technology makes it possible to digitize transactions, compiling and registering them in batches in the form of "blocks". These transactions need to be verified and added to the public ledger at the previous end of the blockchain, allowing each user to verify that each transaction has been completed at a specific time.

Blockchain technology can improve the way data is shared on a global scale. Due to its ideal transparency and public accessibility, blockchain can be used to implement data polling, which is of great significance for activities such as elections where fairness is highly valued. In addition, file storage can also benefit from this decentralized network publishing, ensuring that data is protected from hacker attacks. The sale of intellectual property and creative works can also be carried out more efficiently because the risk of copying is eliminated.

Eliminate the possibility of thinking it’s wrong

The most core advantage of blockchain is that it theoretically possesses a common premise emphasized by all new technologies: minimizing or even completely eliminating the possibility of human error.

Human factors are already the weakest link in all security systems, and the rapidly developing information security industry does have reason to widely adopt blockchain technology. Vance Brown, CEO of the National Cybersecurity Center in Colorado Springs, USA, said that blockchain technology will be able to effectively increase the difficulty and implementation cost of cyber attacks.

In the near future, blockchain technology will rapidly change the way data is managed, helping organizations better protect identity information, businesses and governments to more effectively defend their high-value data, and cybersecurity professionals to use blockchain as a powerful tool to defend against cyber espionage threats.

With its outstanding performance in the Bitcoin field, the resilience of blockchain technology has been strongly confirmed. This stability and scalability advantage is bound to shine in the future network security field.
