Both Bitcoin and Ethereum are based on decentralized blockchain technology, but there are still many differences in deep-seated technologies. Among them, for the specific performance of decentralization, Bitcoin is mainly divided into three parts: complete node decentralization, centralized computing and decentralized development. In contrast, Ethereum's development process is completely centralized, and although this can significantly improve efficiency, it also makes it impossible to guarantee the security of its rules and is vulnerable. Bitcoin, on the other hand, has become more stable, which has laid an important foundation for its steady development and at the same time has determined the safety of investment.
