The trend of blockchain dApps applications is booming with no signs of a slowdown. Businesses are flocking towards this technology for its scalability, transparency, and decentralization properties which can help them overcome many challenges they face with traditional centralized applications.

However, designing a robust blockchain app architecture is not an easy feat. It requires a good understanding of the technology and the various trade-offs involved. In addition, having a scalable architecture is essential for your blockchain application as it will help your business in multiple ways.

A scalable blockchain app architecture can help you save on costs. Traditional centralized applications often require a lot of expensive hardware and software to run correctly. With a blockchain application, you can run everything on a single server or even on a laptop. It can save you a lot of money in the long run.

In addition, a scalable blockchain app architecture can help you increase your revenues. Because of the nature of the technology, blockchain applications can often process transactions much faster than traditional centralized applications. It means that you can potentially make more money by processing more transactions in a shorter period. On this note, let's look at some factors that you consider while designing the architecture.

Factors to consider for blockchain app architecture?

To get started, here are the top essential factors that you can consider while designing an architecture:

Type of blockchain protocol:

Decide on the type of blockchain protocol you want to use for your application. The three most popular protocols are Hyperledger Fabric, Ethereum, and Corda.

Transaction speed:

Another essential factor to consider is the transaction speed. For some applications, it might be necessary to process hundreds or even thousands of transactions per second. It can be a challenge with traditional centralized databases, but it is possible with blockchain technology.

Data scalability:

In addition to transaction speed, you also need to consider data scalability. With a traditional centralized database, you need to scale up your hardware and software when your data size increases. With a blockchain application, you can add more nodes to your network to accommodate more data.


Security is always a top concern for businesses. With a blockchain application, you can ensure that your data is safe and secure. All of the data is stored on a decentralized network of computers instead of on a single server.

User identity:

Another essential factor to consider is user identity. With a blockchain application, you can have complete control over who has access to your data. All of the data is stored on a decentralized network of computers instead of on a single server.

User identity processing and storing become easier with blockchain applications as it provides complete control to businesses regarding data security.


As data is stored on a decentralized network of computers, businesses do not need to worry about losing data due to hardware failure. In addition, you need to consider the cost of developing and maintaining a blockchain application.

While the upfront cost might be higher than traditional software applications, the long-term prices are often lower. There is no need to pay for centralized server infrastructure or security features like firewalls and encryption.

Decentralized apps categorization

To help you understand better what apps can help you in the business scalability, here are a few that we've listed to get you started:

Record keeping dApps:

These decentralized apps offer a secure, transparent, and tamper-proof way to store data on a blockchain. Because each transaction is immutable, dApps that manage records are valuable for maintaining ledgers of sensitive information such as medical histories, banking records, and voting results.


Decentralized exchanges facilitate peer-to-peer trading of cryptocurrency and digital assets without a third party. In addition, because they run on blockchains, these exchanges are resistant to outages, hacks, and other common problems faced by centralized exchanges.


A DAO is a decentralized autonomous organization that cooperates according to transparent rules encoded on the Ethereum blockchain, eliminating the need for a central authority. Several popular projects, including MakerDAO and Compound, have launched DAOs to fundraise, manage financial operations and decentralized governance.

Identity and access management dApps:

These decentralized apps allow users to control their own digital identities and data. uPort and Sovrin are two examples of identity dApps that give users the ability to securely login to dApps and services without needing a central authority.

Consumer-focused dApps:

Several consumer-facing dApps have been built on Ethereum, including the popular cryptocurrency games CryptoKitties and EthDogs. These apps allow users to interact with each other in a decentralized way and demonstrate the potential of blockchain technology for building new types of social applications.

These are only a few examples of the many different types of decentralized apps that have been built on Ethereum. With the growing popularity of blockchain technology, we can expect to see even more innovative dApps categories in the coming years.
