Blockchain vs DataBase: The Secure One
There is no surprise that all of us, one way or another, are drawn to blockchain technology, however, when it comes to the relationship between blockchain and database, we all are not sure how they both integrate. And, to ease up that confusion, we have explored that relationship with the comparison of blockchain and database.
For a new user, both technologies might look the same. However, that’s not accurate even though many people think blockchain is just another database. Data storage preferences databases and blockchains are architecturally different and have various sets of assets, vulnerabilities, and challenges.
The database system is designed as per client-server architecture and can run in short and large-scale requirements. In database storage, the client operates as a receiver, and servers the store data site– used as a Central Processing Unit. Firewalls and anti-malware tools supervise every kind of data and data exchange among customers and servers.
On the other hand, blockchain storage is in absolute opposition to the client-server network architecture of centralized databases. It is decentralized storage running on a peer-to-peer system of dispersed ledgers. Data is collected in the public or individual blockchain in a previous block that is secured by a cryptographic hash.
To understand the security as well as other aspects of these two technologies, let's explore how blockchain is different from databases, and the comparison of blockchains versus traditional databases will help you to determine how different they are and which one is secure and best for you.
2. What is Blockchain?
Blockchain is a distributed ledger technology that facilitates a faction of companions to operate together to form a centralised and decentralized network. The companions can interact and share information or data with the aid of the consensus algorithm. Besides, there is no requirement for a centralized authority, which executes the entire system reliably and securely compared to other systems.
3. What is Database?
Contrary to blockchains, the database is a centralized ledger that is managed by an executive. Databases also present different features, combining the strength to read and write. Just the people with peculiar access can do Write and Read operations.
Databases also manifest the knowledge to store many examples of the same data stored along with their records. This is prepared with the guidance of a trusted, centralized professional who maintains the server. Centralization serves many advantages to the database. For instance, it is simple to maintain databases as the data is centralized.

4. Blockchain vs Database: Which one is the secure option?
4.1 Authority and Control
Decentralization draws in a set of implementation transitions to the modern methods and processes practised by the various industries. It allows networks to operate autonomously and eliminates any necessity for centralized control.
But the database function is totally working on the centralized features. No traditional database is supported by decentralization. If you are particularly searching for a decentralized database, then blockchain is the one for you.
Architecturally, both blockchain data structure and database are varied. Let's explore the discrepancy between the blockchain database and the traditional database structure.
A database works on client/server architecture. It is a profoundly thriving architecture that can run in both small and large-scale settings. In this case, the customer is the receiver, whereas the servers work as a centralized processing unit. The interaction between customer and servers are managed through a secure connection.
On the other hand, Blockchain practices a shared ledger network architecture. It is an enabled network where every companion can join with another utilising secure cryptographic protocols. As there is no centralized link, nodes can collectively take a role in the consensus algorithm for backup and recovery subsystems.
4.3 Immutability and Data Handling
When it is about data structure, storage and approach, both blockchain and database work adversely. In a traditional database, data can be saved and retrieved with ease. To assure the proper operation of the app, CRUD is used at the initial level.
CRUD basically means Create, Read, Update, and Delete. This also suggests that you can retrieve data, erase it and replace it with different values if required.
Blockchain works otherwise when it is about data storage. Blockchain encourages immutability, which indicates that data once is recorded cannot be deleted or returned. Immutability indicates that no data tampering is plausible within the system.
The centralized database doesn't present immutability and therefore are more inclined to be handled by a manager or third-party hacks. That means, blockchain only recommends two operations, Read and Write Operations.
4.4 Speed and Performance
The speed of performance is also a crucial phase that we require to associate both blockchain and database. Databases are identified for more agile execution time and can also manage several data at any time.
Blockchain is kind of slow when connected to databases. But, it can as blockchain is a comparatively latest technology and still requires a lot of time to develop and level to the measures of well-aged technologies like databases.
When a purchase is sent out in the blockchain, it makes all the information that a traditional database does. Although, it is slower as it has more operations, such as:
- Signature Verification: Blockchain actions, when taken out, are cryptographically approved utilising cryptographic algorithms.
- Redundancy: Blockchain is a whole system where every node performs a significant role. To guarantee that every node can strive, each transaction data requires to be collected and tested by each node.
- Consensus Mechanisms: As blockchain is decentralized, it depends profoundly on a consensus mechanism to verify transactions onto the blockchain.
Another essential feature that blockchain gives is that using the best tool, anyone can review the data once inscribed into the free blockchain. Transparency guarantees that the people can trust the system.
As we all know that databases are centralized, it doesn’t hold any kind of transparency. Users can't check the data if they need to. Although, an executive can make a collection of data public, but yet, the data confirmation can't be performed by an individual.
Blockchain’s sincerity is what made it happen because of the immutability it has to give. Data, once collected cannot be altered or modified in any way, which means that the data sincerity is sustained at any value.
5. Blockchain vs Database: Best Use Examples of These Technologies!
So far we have covered some essential differences between blockchain and databases, it is time for us to learn about the best use examples for both of them.
5.1 Databases Use Cases
The best use problem for databases is business solutions or systems. The purpose after it is how the database works and yields balance to the entire network.
Databases are unquestionably user-friendly and are now held by a well-known database management system for developers and managers. Even websites with numerous users depend on databases to help with content. Forbes, for instance, utilises a database in association with high-end operations.
5.2 Blockchain Use Cases
Blockchain’s design is totally different. It is a peer-to-peer system that places two essential things on its users, such as transparency and security. The shared ledger is what makes it different. It can transform how an application works and improve every particular feature of it.
Any system that needs peculiar verification can use blockchain. For instance, B2B Business-to-Business businesses can profit immensely.
Now as we have discussed the data storage techniques, the decision of choosing your next data storage technology is not a difficult one. In this post, we have gone through the important variation between them, and both traditional databases and blockchain are best.
The database is best when we talk about its use, speed, and efficiency. On the other hand, blockchain is best when it is about modification, verification, and automation.
It might look unusual that databases will always provide the model of robustness that the remarkably co-ordinate blockchain does, and it's sceptical that blockchain will ever provide the standard performance of databases. Thus, select as per your necessity, understand their benefits and drawbacks then pick one.
