“ I hope blockchain is like the Internet , Become the bottom facilities of production and life .”—— Li Jun, director of block chain laboratory in xiong'an new district
On the way to the future
2020 year 12 month 14 Japan , The underlying system of xiong'an blockchain 1.0 Release . This means that the first city level blockchain underlying operating system in China has been developed and put into use . The underlying system of xiong'an blockchain 1.0 Self control , Adopt independent intellectual property technology , Built a “ Core chain + Application chain ” A new underlying architecture of blockchain with multi-layer chain network integration , In throughput 、 Cross chain collaboration 、 Data trusted exchange 、 Safety and other pain points have achieved innovative breakthroughs .
