According to Ant Jinfu today, Alipay's blockchain technology has added new scenes. Recently, the Yunnan Provincial Department of Finance opened the country's first blockchain electronic bill. This blockchain electronic bill was issued on September 25 this year. It comes from the school charging scene. There is a QR code at the top right of the ticket. After scanning, it is the only “ID card” to ensure its authenticity. In the future, in addition to school fees, Yunnan Province will also drop regional block electronic bills in many livelihood services such as medical care, education, public welfare funds, penalties and parking.
