Blockchain vs Traditional Database – LCX

Everyone in the world has been introduced to the term “blockchain” in one way or another. This technology has revolutionized the digital world. We are all aware of its importance in the financial sector, but this technology opens new perspectives in almost all fields. Companies or even individuals wish to have more transparency in their activities, and Blockchain provides a well-secured and safe system.

Blockchain is considered a database, and although it is similar to traditional databases in some ways, the two are fundamentally different.


Several decentralized nodes constitute blockchain databases. Each node helps with administration because each of them has access to upload new data to the database and check for the latest updates on Blockchain. A majority of nodes must achieve consensus before the addition to the Blockchain can be made. This consensus technique controls the security of the network and does not let it be vulnerable to malicious activities such as hacking.

Traditional database

Client-server network architecture is used in traditional databases. A user (called a client) can modify the data stored on a central server. The database is controlled by a certain authority, which verifies a client’s credentials before granting access. Since this authority is in charge of database administration, data can be compromised if the security of the authority is removed or compromised.

Difference Between Blockchain and Traditional Database

The blockchain does not have a centralized control system. It allows multiple parties to share data without the need for a central system or administrator. As a result, the data is kept secure. The administrator has authority over it from a central location. Any change in the data can cause the information to change everywhere. Anyone with access to the centralized database can corrupt or destroy the data. This has led to cases of piracy and counterfeiting.
Blockchain technology faces scalability issues due to its reliance on all decentralized nodes. Because permissions are centralized and the power to modify data is in the hands of a few, traditional databases can handle huge volumes of transactions per second. The client-server design reduces reliance on nodes, which are replaced by isolated server centers.
Blockchain has the potential to enhance data transparency and trust, which results in increased creativity, productivity and quality. Traditional databases fail to provide the level of transparency offered by BlockchainBlockchain.
Cryptography is needed to hide information on Blockchain. There is no confidentiality of information. Everyone in the system is aware of this. With regard to traditional databases, the information is only accessible to members.
As Blockchain is a distributed public ledger, it cannot be personalized by an individual’s choice. A traditional database offers many customization choices. Permissions, privileges, and configuration requirements can all be optimized because traditional databases are centrally managed. Developers can update the frontend and add plugins to the database to make it customer-centric.
The user can bring more data in the form of additional blocks into the Blockchain. Old data will not be destroyed; it will remain in the system and will be publicly available. The client performs four roles in a typical database: create, read, update, and delete. These are the four steps of the CRUD process.
Current information and information that was previously available coexist. It generates a database with its history. This property of Blockchain makes it convenient for tracing records and determining the validity of a product. The information contained in a centralized or traditional database is up to date at all times.

Use Blockchain to:

  • Real-time data exchange
  • Financial transfer
  • Identification and authentication of records
  • dApps (decentralized applications)

Use the traditional database to:

  • Relational data
  • Confidential files
  • Conventional storage systems
  • Data that would be frequently modified


Choosing your next data storage technique is not difficult. While databases are faster and more accurate, Blockchain offers innovation, verification and automation. Due to its verification approach, Blockchain has a performance constraint. This obviously indicates that Blockchain should be avoided if execution speed is critical. When a critical business process needs to be supported or scaled concurrently, traditional databases are an excellent solution. When it comes to Blockchain, the process of reading and writing is also not straightforward, which makes the database more attractive for general-purpose applications. Finally, if you want trust, transparency and verification, Blockchain is the way to go. In contrast, traditional databases are suitable for high-performance services or applications.
