Titanium media released an article today saying that at present, the blockchain test in the financial industry is still in its infancy. There are relatively many cases in the field of bills, and they are relatively mature. Some areas try blockchain auditing, but only in the stage of technology exploration, no effective progress has been made in other areas. Blockchain invoices are the most widely used scenario for the current blockchain in the financial sector. However, unlike foreign countries, the domestic penetration rate of blockchain audit scenarios is not high. At present, most of them are still in the stage of technical envisioning, and development is relatively weak, and only a small number of projects achieve the scene.
