Compare Blockchain and Relational Database

I, Arslan Mirbzergi, in this article, I’m going to familiarize you with the difference between Blockchain and Relational database. Since the term “Blockchain” is not clearly meaningful, you can describe almost any IT project using Blockchain. Blockchain, which uses the digital currency Bitcoin, is designed for use by Non-trusting groups and does not require central management. If you need a way to transfer peer-to-peer that can’t be shut down by one or more governments, this type of design may be suitable. But it is less logical and convenient for a database that supports critical business processes.

Since the requirements for a database that supports Bitcoin’s performance are likely to differ greatly from those of a database that supports a common trading trend. A solution that is suitable for Bitcoin may not be the best choice for other things. So the question is, in what areas is the use of Bitcoin-like blockchain clearly better than using a Relational database?


Is reducing intermediaries important for Blockchain?

The purpose of Disintermediation or demediation for third parties may be a good target for Cryptocurrency. Especially if you are concerned about preventing government agencies from interfering. Of course, it’s not necessarily a good target for Enterprise software. The potential cost of Saving in using Blockchain comes from the fact that a running Blockchain program doesn’t require much support because you can rely on other organizations instead of other internal managers to keep the distributed database active.
But if you’re building a Blockchain-based app yourself, you’ll probably need to provide support and maintenance as well. Research shows that the cost of supporting and maintaining the software is at least as much as the cost of producing it. This shows why software vendors charge too much to support and maintain the product. As a rule, you should keep in mind that if you have written an app that uses Blockchain, you will pay at least as much as you spent during the life cycle of the app during its development.
According to this view, the costs of using internal database managers are not so bad. Removing the intermediary that uses Blockchain may result in significant cost savings in the long run. Of course, this does not mean that there will always be significant benefits from the elimination of the interface.

Performance penalty

While other features, such as the ability to take Double-spending and the ability to withstand malware, are more important than Performance for Cryptocurrency, very high Performance is often the target of databases that support important and vital business processes. Unfortunately, features that use Bitcoin-like blockchain also significantly lower Performance. Especially, while the writing speed in a Relational database (RDBMS) is too high, writing in Bitcoin’s blockchain is considered hard to write in order to prevent Sybil attacks, and as a result, it is relatively slow. Blockchain requires the use of a lot of resources that you have to pay for.
Bitcoin miner, people who write updates about Bitcoin’s blockchain. These people currently receive more than $7,000 (on Bitcoin) for each update. Without this motivation, almost surely no updates would have been made. Performance penalty is also intended for other intermediary approaches, none of which are as burdensting and costly as the approach pursued by Bitcoin. But they all include some kind of performance penalty.


Important: If you need a high performance for your program, a Relational database (RDBMS) may be a better option than Blockchain. In fact, it is difficult to realistically say in what cases the use of a system that uses Blockchain works better than a relational database-based system (RDBMS). As well as a Bitcoin-like blockchain, it may be an important obstacle in scaling up the performance of your application.

Fault-tolerance coefficient

The Bitcoin network has many users, each of which performs a number of required processes for Bitcoin transactions. A useful result of this huge level of redundancy is the high level of Fault-tolerance in Bitcoin. A situation where hacker attacks are enough to incapacitate the Bitcoin network to prevent transactions from being processed is extremely rare.
It is very difficult to achieve the same level of Robustness in a Relational database (RDBMS) or to do it at the right cost. The most robust implementation of a Relational database (RDBMS) will achieve the same level of Robustness in a large, parallel Bitcoin network. If the ability to withstand any kind of attack is important to you, choose Bitcoin-like blockchain. This tool gives you a level of Fault-tolerance that is difficult to achieve using other methods.

Data Security

A Bitcoin-like blockchain is completely visible by everyone. This means that the confidentiality of any data stored in it is basically zero. However, in the business world there are good reasons not to make the data public. Sorted data certainly cannot be public. Many businesses do not want to disclose data such as transactions involved. Therefore, it seems that a generic Bitcoin-like blockchain is not very usable for use in many trading applications. However, all records of a Transaction do not need to be stored in Blockchain. Instead, you can save only one Cryptographic hash of them, which is enough to solve the problems. It is possible to obtain a reasonable level of data confidentiality with Blockchain.
Bitcoin’s blockchain cryptographically links any blocks added to it. So the change in each block is easily accessible. Given that Blockchain records any Transaction related to Bitcoin, it is easy for a Relational database (RDBMS) to register any SQL commands it receives from the Client. Digitally signing data written in a Relational database (RDBMS) is easy. Therefore, it is easy to cryptographically guarantee that the data written in that database has not changed. Therefore, there is no difference between blockchain orRelational (RDBMS) databases in relation to integrity data support.

Blockchain vs. Relational Database

Blockchain and relational databases (RDBMS) are both useful tools for storing information. These tools support vital business processes. Also, each one excels in different fields over the other. The advantage of blockchains is to provide a Robust and Fault-tolerant method for storing important data, and relational databases (RDBMS) are superior to Performance. It seems unlikely that relational databases (RDBMS) will ever be able to support the level of Robustness that fully parallel Blockchains offer. Also, Blockchains cannot provide the same level of Performance Relational databases. In other contexts, neither of these two databases has a clear advantage. For example, it is unclear whether the profits from the elimination of mediation, often referred to as the main advantage of Blockchain technology, will be realized. While the costs of supporting and maintaining a Blockchain-based program are taken into account.
But there are also Smart contracts in the world of Relational databases (RDBMS), known as storage methods. Anything that can be achieved with one technology can also be realized with other technology, so it should be checked whether using one of the technologies is right for your work.

And in the end,

The question is, how should you choose between Blockchain and the Relational Database (RDBMS)? When checking which technology is best to use to support your next apps, be sure to analyze exactly your needs and how any database is supplied or not. Don’t let the arguments of the proponents of any of these technologies convince you that their methods are better. Make decisions dedituts during a detailed analysis of your needs.
