The healthy operation of digital finance is inseparable from effective supervision. At present, the blockchain still has certain problems in digital financial supervision. Blockchain technology can improve the security and controllability of the blockchain system by controlling membership, but it cannot ensure that all parties will not conspire to tamper with the basic agreement and ultimately harm the interests of other participants. This article takes the impact of high-performance computing and blockchain technology on the information disclosure and prediction of stock issuance as the research object, and selects the stock and stock index data disclosed by the stock issuance information of 100 listed companies on the Google Finance platform as samples, including daily opening prices, highest price, lowest price, closing price, transaction volume and adjusted closing price, among which the adjusted closing price is used as the target variable. The stock price data and transaction volume data are taken as input feature parameters at the same time, and normalized, and a stock prediction model suitable for different situations is established: CNN network model based on the distributed mechanism of blockchain technology to predict the stock issuance. The research results show that only when the application cost of blockchain technology is controlled within a certain range, that is, when the BC is 36.01, can the losses caused by the many drawbacks of the traditional model be compensated, thereby promoting the active use of the technology in the securities market. As far as each node company in the securities market is concerned, blockchain technology has helped stock issuers to increase their income most significantly, so they can bear more technology application costs.
