Guizhou's first intl block chain standard wins approval

The requirement for distributed ledger systems was recently approved by the International Telecommunication Union, becoming Guizhou's first international block chain standard to be approved.

Research into the standard, which started in January 2017 and finished in March 2019, was led by a Guiyang-based technology company. It was also the first international standard in the big data area approved since the construction of a national technical standard innovation base in Guizhou.

The company's another research into a block chain standard, known as the distributed ledger-based digital evidence service, is in progress.

The distributed ledger is a database that can be simultaneously shared, copied and uploaded between network members. It records the currency transactions between different members and can reduce the time required and costs.

The International Telecommunication Union focuses on telecommunication standards set by the United Nations. It carries out research on the telecom spectrum and assesses standards of various emerging network technologies.
