Impact of Blockchain on China’s Cyber Statecraft: Opportunities and Risks

Since 2016, China has officially regarded blockchain technology as a subversive innovation that will fundamentally transform major industries. Current blockchain projects in China are dominated by private or consortium blockchains that have their accessibility firmly controlled; for public blockchains such as Bitcoin and Ethereum, access is free for all. Not surprisingly, by weakening state control of digital data, public blockchains may neutralise China’s decades of efforts in building internet filtering systems. The existing development trajectory of private and consortium blockchains is likely to advance steadfastly, and citizens and companies in China may be required to use state-controlled blockchains.
