We discussed several benefits of blockchain technology in general in Chapter 1, Blockchain 101. While all those benefits are attainable using public blockchains, several features are lacking in public blockchains, which makes them unsuitable for use in enterprise use cases. The interest in enterprise blockchain arises from these limitations in public blockchains, along with specific requirements in any business.
We'll describe some of the most common concerns next.
Public blockchains are slow and can process only a few transactions per second. Bitcoin processes 3-4 transactions per seconds, while Ethereum processes around 14. This low transaction rate is not suitable for businesses that usually require high transaction speed. For example, card payment businesses typically need to process thousands of transactions per second.
