On August 20th, the "POW'ER 2019 Global Developers Conference" hosted by Mars Finance was held in Beijing. Wang Menghan, the product manager of Ping An Financial's account-blocking block chain, said in the speech that the current blockchain application has encountered three major bottlenecks: 1. Data privacy issues, traditional blockchains need to share account information between competitors, exist Data privacy leakage risk, data security and difficulty in risk control; 2. System ownership disputes, such as who dominates the blockchain system; 3. Performance choices, such as "large block" high throughput and high latency, and "Cell block" low latency and low throughput, low latency & high throughput cannot be achieved.
