China has focused on tackling core underlying technologies in the field of blockchain, making breakthroughs that have materialized a trusted digital infrastructure with a "Chinese core," said Dong Jin, director of the Beijing Academy of Blockchain and Edge Computing, on Thursday.

Dong made the remarks at the Deputies' Corridor ahead of the opening meeting of the fourth session of the 14th National People's Congress (NPC) at the Great Hall of the People in Beijing.

"Blockchain technology is a cutting-edge information technology," said Dong. 

Blockchain ensures the authenticity, credibility and traceability of data, which is one of the three key elements of artificial intelligence, together with algorithm and computing. It can be said that in the process of digital economic development, blockchain is one of the most crucial digital infrastructures.
