How do APIs work, and how are they different from blockchains

APIs and blockchain technology have much in common, yet they offer fundamentally different solutions to data storage and access challenges. Both technologies have become increasingly popular with developers due to their potential for improving the efficiency of operations and offering new tools for creating innovative applications. This article will explore the similarities and differences between APIs and blockchain, what types of businesses are best suited to each technology, and the benefits and drawbacks of implementing them in your organization.

What are APIs? 

An Application Programming Interface (API) is a software-to-software interface that allows two programs or systems to communicate without user intervention. Developers commonly use APIs to simplify integration with external systems and create powerful tools that can be reused throughout an entire software system. A common example of an API would be a website’s ability to interact with its backend database, allowing it to pull data and present it in a desired format.

What is Blockchain? 

Blockchain technology is an open, distributed database of records that records transactions between two parties securely, permanently, and verifiable way. It was originally developed as the underlying technology behind Bitcoin but has since been adapted for many other applications, such as digital identities, smart contracts, and supply chain management. At its core, blockchain technology provides a secure method for logging data across multiple computers or databases without requiring centralized control or administrative oversight. This makes it potentially more resistant to tampering and fraud than traditional databases.

APIs vs Blockchain

Although both APIs and blockchain technology are used for data storage and access, they offer different solutions to the same problem. APIs provide a simple way for developers to access external systems, while blockchain provides a secure alternative to traditional databases, resistant to tampering and fraud. Additionally, APIs are most suitable for applications where speed and scalability are paramount, while blockchain is more suited to operations requiring greater security or privacy levels. Ultimately, the decision between using an API or a blockchain will depend on the specific requirements of the application being developed. 

Five benefits of using APIs over blockchain

Faster and more efficient:

APIs are generally faster than blockchain-based systems and can be used to access data from external sources quickly. 

Easier integration:

APIs provide an easy way for developers to integrate existing software solutions with new applications, meaning users don’t have to learn how to use a new system. 

Lower cost:

Implementing APIs is typically cheaper than blockchains due to the infrastructure required for the latter technology. 

Higher scalability:

APIs enable developers to quickly scale their applications as demand increases, making them ideal for rapidly growing businesses or enterprises with large customer bases. 

More control:

Since API calls are processed within the same system, developers have more control over how the data is used and secured. This makes APIs better for applications requiring tight security or privacy measures. 


APIs and blockchain technology both offer powerful solutions to data storage and access challenges. However, when deciding which technology to use, it’s important to consider the specific requirements of your application and ensure that you choose the best solution for your needs. APIs are most suitable for applications requiring speed and scalability, while blockchains provide more secure alternatives for operations with tighter privacy requirements. Ultimately, whether you opt for an API or a blockchain will depend on what type of application you are creating and the specific goals you want to achieve with it.
