According to the People's Daily News, on April 19th, the country's first blockchain notary was opened and used at the Beijing CITIC Notary Office. The person in charge said that the move marks the beginning of a new stage in the development of the notarial certificate and the official opening of the blockchain notary service era. The notary of the CITIC Notary Office introduced that the application of the blockchain notary certificate enables the certificate holder to verify the contents of the notarial certificate by scanning the two-dimensional code on the paper certificate. The blockchain notarization is effectively prevented by the blockchain technology. Paper document fraud, paper stamping and other issues have greatly improved the verification efficiency of notarization under information asymmetry.
