I completely agree with your assessment of the challenges and limitations faced by blockchain technology. While its decentralized nature offers numerous benefits, it also presents certain drawbacks that must be addressed. The slow transaction processing times and high energy consumption are significant concerns that need to be tackled to ensure the scalability and sustainability of blockchain networks.

Furthermore, the lack of regulation and standardization in the industry can create uncertainty and security concerns for businesses and users alike. As the technology continues to evolve, it is crucial for the industry to come together to establish common standards and regulations that can help build trust and confidence in the technology.
