When you are interested in getting to know more about Blockchain, then you will find this technology often compared to a Database. Reasons for interest may vary from just curious to have an interest in getting the experience of digital transactions quickly, cheaply and practically. What is clear, Blockchain and Database are often linked, even though they have subtle differences.

Especially for beginners in the digital business field, do not yet be immediately confused to understand what Blockchain is. Because in this article, we will help you understand the relationship and differences between Blockchain and Database. With this explanation also, it is hoped that a comprehensive understanding and application of Blockchain will emerge.

What is Blockchain?

The best definition for Blockchain is a distributed ledger technology. Satoshi Nakamoto was the first person or group or institution to introduce it to the public marked by the appearance of Bitcoin in 2009. As Bitcoin became a digital currency, Blockchain began attracting the virtual public’s attention to large corporate classes.

In fact, since its inception, Bitcoin has become the most popular in cryptocurrency competition. With blockchain technology, this currency makes all digital transactions possible without bank intermediaries, making it easier and safer. This is due to the use of distributed ledgers that allow the recording of operations to be accessed by anyone, aka decentralized, as well as creating a secure network, difficult to hack and integrated into nature.

How Blockchain Works

Blockchain supports the smooth and transparent operation of digital transactions by adhering to three working principles, namely decentralization, transparency and settling. For example, in a digital deal, sending information from one partner to another through bitcoin future The purchase must be validated using a consensus algorithm.

Blockchain, in this case, is tasked to record all transactions that have been validated in a block, and then integrated into a chain of embedded blocks. Blockchain only records valid transaction results; aliases cannot be changed. The principles of transparency and decentralization allow blockchain to be accessed, tracked and verified by anyone.

After getting an understanding of the blockchain, let’s go find out about the database. That way, we can immediately compare the two and see the difference between the two.

If the blockchain is anyone who can access decentralized alias, then Database is the opposite. It is a giant, centralized ledger and can only be accessed and run by specialized administrators. The database also displays several unique features so that we, as consumers, easily understand the reading or writing of the data.

But of course, not everyone can read and write databases carelessly, because they need to get permission from the administrator first. Databases held by a centralized authority usually store many copies of data for server management security. Data copy is essential because the data stored is vulnerable to damage. Another risk from the database is that data is susceptible to modification if the administrator is weak in terms of security.

Compare blockchain and database

To more clearly compare blockchain and database, let’s see how it works. Databases rely on data structures to store information. The stored data can be queried using a select query language called Structured Query Language (SQL). Databases have long relied on several modern companies to support millions of essential records.

The database also has a long history, starting with the file hierarchy system. But this system has a severe limitation because there is system improvement to the relational model. This model allows the owner to work with different databases simultaneously. Several database management systems are also implemented so that their use is always active.

There are various types of blockchain. One that is often equated with databases is a private blockchain. This is a kind of blockchain that is used by certain groups. This means that even though it is decentralized, it can only be accessed by certain people. Both are similar but remain different. Database and Private Blockchain are equally limited in terms of access. Participation in it is only possible if it has been through administrator permission. But the two are clearly different from the following criteria.
