The ability to quickly adapt to new technical trends and the urge to execute amazing, out-of-the-box solutions can be stressful for enterprises. Will this, however, shield such enterprises from competitors? Of course, the answer is no!


Firms are discouraged from implementing new technology due to a lack of knowledge, organisational structure, and concern about how it will affect their bottom line. One such conundrum is deciding whether to adopt new blockchain technology or remain with traditional database management methods.


So, in this essay on blockchain vs. database, we’ll go through both technologies, explain how they might be used, and discuss some of their potential applications.


What Exactly Is Blockchain?


Using blockchain, a Distributed Ledger Technology, a group of users can work together to create a consistent decentralised network (DLT). These users can communicate with one another using the consensus technique to exchange information or data. The blockchain lacks a central controlling body to safeguard the network’s integrity.


Blockchain is not just a random piece of technology; it is the next stage of the technological revolution, which is discovering new applications every day. Due to its numerous noteworthy properties, Blockchain is one of the developing technologies that is making inroads into a range of businesses. It is also one of the most promising technologies with the ability to change the planet.


What Is A Traditional Database?


Because the typical database is a centralised ledger administered by an administrator, some of these special features, as well as standard read and write features, are disabled. In a normal database, parties having the requisite access can read and write.

A traditional database can be changed, administered, and governed by a DB Admin, who has complete control over the database. Among other things, the database administrator can reduce the size of the database to more manageable levels and optimise database performance. Administrators frequently utilise optimization techniques to improve speed because a large database might become slow.


The Difference Between Blockchains and Databases


Now that we’ve defined and explored what a blockchain and a database are, let’s look at how they differ. The primary differences between the two technologies are described below.


  • Command

The most crucial distinction between a blockchain and a database is this. Traditional databases cannot be downloaded since they are physically centralised on a single server.The designated authority retains control of the database and checks the client’s identifying documents before granting access to it.As a result, the database is operated and managed by one person or a small number of people.


In contrast, the blockchain is designed to run with input from every network user. To put it another way, peers within the system can communicate with one another without the necessity for a central administrator’s approval or oversight.


Before any data can be added to a block, the majority of the nodes must agree. This agreement ensures the network’s security and makes it difficult to mess with.


  • Construction

Another major contrast in the blockchain vs. database argument is the architecture used by each. A typical database, for example, has a client/server architecture that has proven to be suitable for both small and large-scale businesses.


The server acts as a producer in this paradigm, while the clients operate as users or consumers. Clients can thus request and receive services from a server, which acts as a centralised processing unit.


technology, on the other hand, employs a distributed ledger technology architecture. As a result, it operates as a peer-to-peer network, with one peer interacting with another via secure cryptographic protocols.


Each peer has a copy of the original chain and serves as a server (also known as a node) for the network, verifying the transaction block. Each node can perform either one or both mining tasks.


  • Permissions

Permissions are driven by databases. The database administrator can specify which “users” are allowed to communicate with the database. Clients seeking to access the database must fit the administrator’s ideal user profile.As a result, a database is designed to limit the number of users who can access it by requiring certain criteria before a user can access or add data to the database.Blockchain can simply be referred to as a permissionless network because there are no constraints specifying who the ideal user is.


Everyone has access to the blockchain and can read the data at any time. Despite the fact that there are numerous types of blockchain, each one has its own set of rules that regulate who can read and update information.


In general, network users have instant access to the blockchain whenever they require it.


  •  By Design, Append-only

Databases are designed to allow for data addition, alteration, and deletion. However, this is not the case with Blockchain. After data has been added, edited, or withdrawn from the chain, it cannot be modified.


Because the information is added to the whole chain in this manner, there is a historical record of everything that has been saved on the data. In other words, a single operation is performed on a blockchain, and anything entered into it becomes immutable and accessible to all.


  • Safety

A significant disadvantage of databases is that the data stored in them is not secure. Unless the entire setup is standardised and adequately managed, hackers may exploit a single vulnerability in the structure, obtaining unauthorised access to crucial information and damaging the enterprise’s operations.


When comparing blockchain versus databases, the former wins since it is far more secure. A blockchain works without a central server by providing each node with a copy of the chain to use as a reference for validating blocks. When there is consistency from a node, the technology will notice the irregularity and promptly correct any wrong information.


Consider this example to demonstrate how blockchain outperforms databases in terms of security. If a peer on the network decides to go rogue and begins manipulating data on the network, the network will readjust itself depending on the copy of the chain with every other node.


A rogue peer requires at least 51% of the nodes to interfere with the network, which is nearly impossible given the large amount of computational power required.


  • Tolerance for Mistakes

Another notable difference between the two technologies is their failure tolerance. If a database administrator is not present, operations can soon get disrupted. Similar to when a server breaks, business operations may come to a halt.


Blockchain is a remarkably fault-tolerant technology since its uptime is dependent on thousands of nodes throughout the world rather than a limited number of servers. Even if a few hundred nodes are shut off, the network will continue to function normally.


 Although blockchain might be considered a form of database because it can store data, comparing it to a traditional database would be inaccurate. The distinctions between a blockchain and a database are obvious, and these distinctions allow them to be used for a variety of purposes.


In practice, it is not so much which technology wins the Blockchain vs. Database debate as it is how useful it is to your goals. Every organisation must know what it wants before deciding between a blockchain and a traditional database.


A blockchain development company can assist you in determining your company’s requirements. As a result, investing in a solid blockchain development business is a critical decision.
