The success rate of blockchain applications in the real economy is below 5% due to several root causes. First, many projects prioritize decentralization over solving clear user problems, lacking practical use cases. Second, high energy consumption and scalability issues, as seen in Bitcoin and Ethereum, hinder widespread adoption. Third, regulatory uncertainty and complex compliance requirements, especially in finance, create barriers. Fourth, the technology's complexity demands specialized expertise, which is scarce in many regions. Finally, vendors often overhype benefits without evidence, leading to mistrust and failed implementations. These factors, combined with slow development cycles and insufficient user feedback, result in projects that struggle to deliver tangible value, as highlighted by studies showing zero success in some sectors.
