The world of blockchain moves fast, and nowhere does it move faster than China. Here’s what you need to know about China’s block-world in the week of Dec. 8 to Dec. 14.

Blockchain in prisons

Chinese media reported on Dec. 10 that 21 prisons in eastern Jiangsu province had successfully passed the Ministry of Justice’s “smart prison” review process. The system is the country’s first attempt to use blockchain technology in managing its prison system. The province aims to set up an integrated online platform to manage the region’s prisons, incorporating more than 800 functions and 1,200 procedures to streamline the assessment of prisoners, administrative rewards and punishments, commutation of sentences, and parole.

  • The Energy Bureau of southwestern Yunnan province announced that the province has stopped all hydropower stations providing energy to “illegal” bitcoin mining.

The Bureau said all power supply to mining companies had been suspended, and most of the mining machines and factories had been dismantled. The official said the clean-up campaign saved about 2 billion kilowatt-hours of electricity a year. (Jiemian, in Chinese)
