Abstract: Clear boundaries of government powers and responsibilities,open information and efficient performance supervision are the key points of the development of a modern financial governance system in line with the law of the market economy.In the process of development around the key points,China's financial governance is faced with the problems of "governance collapse",such as low efficiency in the use of financial funds,imperfect fiscal collection and management mechanism,imperfect budget management system,low financial transparency and so on.The blockchain technology,which is characterized by transparent and traceable information,non-modifiable data and distributed bookkeeping,is intrinsically coupled with the requirements of data disclosure,security and accuracy in financial governance.Blockchain technology helps to improve the ability of financial governance and optimize the financial governance system,but there are still few mature applications in the field of finance and finance,limited data processing capacity,hidden dangers of data security and lack of flexibility,and differences with the government's financial governance concept.In order to cope with these challenges,we should strengthen the attempt of blockchain in the financial governance scene,give priority to the development of inter-institutional alliance chain,strengthen the mixed mode development of centralized core application and non-centralized blockchain application,and promote the innovation of government financial government concept.
