Difference between conventional database and Blockchain?

Introduction: Blockchains are popular because of the underlying technology that provides a highly accurate, immutable and transparent database. Blockchains are a dissected and decentralised system that is influenced by their numerous actors.For further details, check

“So what is the fundamental difference between a conventional database and blockchain?” is a very common question that arises in the mind of people looking out for an upgrade to store data.

To answer this question, we need to look at the key points listed below.

  • Centralization is the most common factor of difference between blockchains and traditional databases. In blockchains, participants of the system receive a safe and secured copy of all records. Hence, viewers can look into the proof of data.
  • Blockchains work like magic when there is any form of inconsistency. Blockchains have the capability to identify and correct information that is unreliable. This is because each actor maintaining a copy of the track records.
  • Unlike conventional databases, blockchains have the innate capability to correct themselves with a well designed coded trade language. This correction is achieved mostly through consensus, as a result, participants happen to trust blockchains more than traditional databases.
  • To understand the point mentioned above it is crucial to decipher how traditional databases work. When businesses work with each other, they almost never share an identical database. The database of the business is usually maintained by a DBA

( Database Administrator). The DBA is usually hired by just one company, so the company that employs the DBA has a higher success rate, with other investors having the least stake in the success of the business. The other stakeholders of the business would never know if any changes have been made in the database. On a more negative note, if any competitor is willing to buy off the DBA, they could nefariously make changes to the database.

  • Unlike the Traditional Database, when blockchains are put to use there are very few chances of failure, mostly because it ensures if any participant makes a change in the database, everyone gets a notification of it. And make corrections in accordance.
  • Due to blockchain’s transparent nature, the smaller stakeholders of a business can trust this kind of system more, as it is fair and unbiased.
  • Traditional databases are known to keep data up-to-date at a particular point in time. On the other hand, Blockchain keeps the information of all time periods stored, which is again difficult to tamper with.
  • Despite the fact that traditional databases have stood the test of time, they are still very outdated, obsolete and slow in relation to certain functionalities. On the contrary, blockchains have presented themselves as one of the best modes of making transactions. However, they also become slow as well, especially when used to store data, it becomes difficult for them to process large amounts of data at once.
  • Another important factor that makes traditional databases less reliable is their centralised system of storage. Once lost, it is difficult to find it back again, blockchains on the other hand tactfully employs the concept of decentralised data storing. It does so, by giving a copy of the old and new records to its users.
  • The basic method by which blockchains store data is by creating blocks. Each block is then liked with cryptography. Square, a block is embodied with a cryptographic hash from the block before, transactional data, and a timestamp. Even the modification of data is restricted by the very design of the system, allowing decentralised control and therefore restricting any form of modification to information by third parties.
  • Conventional databases on the rear end work as a collection of gigantic data and are usually managed by an administrator (DBA), unlike blockchains where all users act as an administrator. The database in traditional methods is put to use through client-server networks, whereas blockchains can be managed online.


However tricky, blockchains present themselves as the future storage spaces for data. Their fair, transparent, immutable and accurate nature draws them a safe passage for completely replacing traditional databases.

We hope this article has thrown light on your perception of blockchains and traditional databases, and how they are different from each other.
