Despite the many benefits of blockchain technology, there are also some challenges and limitations that need to be addressed.

One of the biggest challenges is scalability. The Bitcoin network, for example, can only process a limited number of transactions per second. As the network grows, this limit could become a bottleneck and prevent it from being used for large-scale applications.

Another challenge is energy consumption. Mining cryptocurrencies like Bitcoin requires a lot of computing power, which can use a lot of electricity.

This has led to concerns about the environmental impact of blockchain technology. Additionally, there are concerns about privacy and security.
