blockchain and traditional database models

Blockchain is a decentralized database. It connects computers around the world so that data can be shared and accessed in real time.

You may have heard about blockchain, but you might not know the difference between blockchain and traditional database models.

In this article, we’ll take a closer look at how blockchain and traditional database models are used together to create new systems that allow for secure transactions between disparate parties without an intermediary. We’ll also provide some examples of where they’re used today (like cryptocurrencies)​

Difference Between Blockchain and Traditional Database Models


Blockchain is a decentralized database

Blockchain is a decentralized database. It’s a distributed ledger that records transactions in real time and allows those transactions to be shared among users on the network.

The term blockchain was coined by Satoshi Nakamoto, who published his original white paper describing Bitcoin in 2008 (the first cryptocurrency). The concept has evolved since then and now includes many new types of applications beyond just cryptocurrencies like Bitcoin.

Blockchains are also immutable: they can’t be altered or deleted by anyone without being detected by all nodes on the chain

Blockchain models are secured

Blockchain models are useful for creating new systems that allow for secure transactions between disparate parties without an intermediary. For example, the shared database model might be used in a supply chain management application where multiple organizations share data with each other via a third-party broker or integrator.

Blockchain models can also be used to solve problems involving data ownership, authentication, and authorization. This is because they contain every piece of information about how assets are transferred from one person or entity (e.g., you) to another (e.g., your bank).

In a traditional database, all records are stored in the same place

In a traditional database, all records are stored in the same place. This is known as centralized data storage.

In contrast, blockchain is decentralized because there’s no single authority that controls the entire chain, the entire network runs on its own rules and updates itself automatically based on input from other nodes within that network.

This means that if one part of a network goes down or becomes compromised, it won’t affect other parts of the same platform (or even any other platforms.

By centralizing data into a single location where it can be accessed by anyone who wants access to that information at any time without having to ask permission first and without worrying about what might happen if someone else gains control over this resource we simplify things unnecessarily and make them vulnerable to theft or corruption by third parties who might want access themselves if they could get past whatever protections we had put in place.

In a blockchain, data is recorded in blocks that are distributed to all computers on the network

In a blockchain, data is stored in blocks that are distributed to all computers on the network. Each block contains a linked list of transactions, the same way it would be with other databases like MySQL or MongoDB.

Blocks can also be added to other blocks in linear order, just like how we might add new rows to an Excel spreadsheet.

However, unlike with traditional databases where you’d have to wait for your changes to propagate throughout the whole system before you could see them reflected elsewhere (and sometimes even after), here you can confirm your transaction immediately because it’s already been committed at this point!

The decentralization of blockchain reduces its vulnerability to hacking and increases security

The decentralization of blockchain reduces its vulnerability to hacking and increases security. For example, if you were to take a database and encrypt all of the information in it with a password, then distribute that encrypted file across multiple servers before storing it on some sort of shared storage system (like the internet), then any single server could be hacked with no real consequences.

But when you have a decentralized network of computers running different parts of your system at once each with its own copy the likelihood of someone successfully compromising all those copies simultaneously becomes very small.

Another advantage is that there’s no central point where data can be lost or stolen: if one node goes down or gets hacked while another stays secure, users won’t lose any information stored there unless they choose to access it from somewhere else first.

This makes blockchain ideal for applications where sensitive data must remain private; examples include healthcare records or financial transactions between companies

With blockchain, information remains available on other nodes

The most important difference between blockchain and traditional database models is that with blockchain, even if one computer node holding data fails, the information is still available on other nodes.

Blockchain has a distributed nature, it stores data in blocks that are spread across multiple nodes, making it very difficult to lose all your data if one node goes down.

  • When a public blockchain is updated, such as when a cryptocurrency transaction occurs, the records are available to everyone on the network. This means that anyone can see what has been done in any particular block of data (or “block”).

The blockchain is also distributed across many computers and it’s open source meaning anyone can access and modify its code.

  • A traditional database could be opened or closed depending on who has access to it. But blockchains are always open.

A blockchain is decentralized, distributed, and has no single authority. Traditional databases are owned by a central authority and can be closed to certain people based on their security clearance level or membership in the organization that owns them (e.g., a branch office structure).

Blockchain networks have no single authority to control it

Blockchain networks do not have a single authority to control them; therefore no one can shut them down. This means that if you are using blockchain technology, you can rest assured that your data will not be hacked or compromised in any way.

The decentralized nature of blockchains makes them resilient to attack by criminals or governments alike even if they have access to the entire network’s database or data history, they cannot alter anything without being noticed by all users around the world who contribute their computing power and storage space into these networks’ databases.

This also makes blockchains resistant to malicious actors because there is no central point of failure (like an Internet Service Provider) responsible for hosting your information within its servers spread across millions upon millions of computers worldwide.

Blockchain has more security and transparency of records

Blockchain models offer many advantages over traditional databases for certain applications including more security and transparency of records.

Blockchain is a decentralized database that can be accessed by multiple parties without the need for an intermediary, like a bank or government agency.

This makes it more difficult to hack than centralized systems because hackers would have to get access to every single computer on the network in order for them to gain access.


Blockchain models are a good fit for certain applications and use cases. The key takeaway is to remember that any database model can be applied in different ways, and blockchain isn’t necessarily the best option for every situation.

Reading this article, we believe you now have a better understanding on the difference between blockchain and traditional database models.

Just because one might be better than another does not mean that any other database model cannot also work well in your project.
