Babbitt reported that on September 26th, the ant blockchain ecological summit was held at the Yunqi Conference. Lan Yiming, a senior expert on financial bills of the Zhejiang Provincial Department of Finance, said that in June 2019, Zhejiang Province launched the first blockchain electronic bill platform in China. In the next step, the inter-provincial interconnection system of the electronic bar of the Yangtze River Delta blockchain will be established. Through the blockchain cross-chain interconnection technology, patients can apply for inter-provincial reimbursement only through mobile phones, and the medical insurance department can directly use the blockchain electronic bills. After the online review, the reimbursement funds will be directly credited to the insured account.
