Blockchain Misuse: Hype or Innovation?
This article critically analyzes the current state of blockchain applications in areas such as supply chain management, object authenticity verification, statement authenticity guarantee, voting, proof of authorship, and land registry. The author points out that many seemingly logical blockchain solutions ignore the core issue of 'blockchain is not the Internet of Things (IoT)', leading to difficulties in guaranteeing data authenticity. The article argues that in many scenarios, distributed databases or digital signatures can solve the problem without the complexity and resource consumption of blockchain. The author believes that currently, only in the area of value transfer does blockchain (such as Bitcoin) demonstrate true value, while the application prospects of smart contracts remain unclear.
