Blockchain scalability and Cardano approach to it

The public blockchain struggles with adoption. Higher adoption is critically dependent on the ability of the protocol to scale more. Let’s explain exactly what scalability is and look at the differences between PoS and PoW.

How to define scalability

The standard Wiki definition might sound like this:

Scalability is the property of any system to handle a growing amount of work by adding more resources to the system.

Scalability is the ability to handle multiple requests as the user base grows. User growth often reaches the point where resources need to be increased to maintain the quality of service at the expected level. Increasing scalability often entails extra costs.

Few services or protocols are built from the outset for mass adoption. The success of the service is difficult to predict in advance. Therefore, the number of users is only estimated in advance and the service starts. As the service becomes more popular, users may see a slowdown in response, for example. This is because the number of users is growing and existing hardware is overloaded and does not manage to handle new user requests.

Let’s try one analogy from the real world. Imagine a clerk at the post office. The clerk can handle 10 customers per…
