3  BLOCKCHAIN 
CONSTRUCTION OF 
EMERGENCY SUPPLY CHAIN 
MANAGEMENT 
In the face of large-scale disasters, people are often 
unable to return to their posts normally, which leads 
to different degrees of shutdown of enterprises in 
various places. Reasonable emergency resource 
supply chain management will become the logistics 
support for all kinds of materials, and prevent the 
domino effect of shortage of medical and livelihood 
materials. In the COVID-19 epidemic prevention and 
control at the beginning of 2020, many places from 
Hubei to Jiangsu, Sichuan, Guangdong, Fujian and 
other provinces have experienced shortages of 
medical supplies to varying degrees, and there have 
been typical cases of local governments withholding 
foreign supplies. In the blockchain system, other 
business subjects can conduct dynamic real-time 
supervision and interaction on the transaction 
behaviour and distribution activities of suppliers, 
which will greatly improve the efficiency of 
emergency resource management and logistics 
distribution. The supporting policies for the strategic 
management of emergency resource supply chain 
under the blockchain technology will certainly 
become the focus of relevant policy research. 
Blockchain construction needs strong support 
from the local Fujian government. Therefore, the 
research group puts forward the following 
suggestions to the government: 
First, data structure isomorphization design and 
transformation. Considering the strategic height of 
block chain technology, the provincial overall 
planning leading group and the expert committee 
shall be established as soon as possible, and invited 
experts from home and abroad to participate in the 
planning, positive preparation of the various types of 
heterogeneous systems based on the relationship to 
the national economy and people's livelihood 
TongGouHua database data structure design and 
modification, and timely complete block chain data 
synchronization. 
Second, set priorities and try first in some areas. 
In order to achieve the goal of the integration of 
blockchain and economic and social development, 
priorities should be set, and some fields should be 
tried first. Blockchainization of some livelihood 
systems can be tried first, such as industrial and 
commercial data of enterprises, financial and taxation 
data of residents, medical insurance and social 
security data of residents, household registration data, 
medical data of hospitals, industrial and commercial 
data, judicial and legal data, traffic 
management/administrative service data, and then 
extended to financial and energy data. 
Third, moderate technical expansion on the 
original infrastructure. Different industries have 
different information architecture foundations, and 
blockchain algorithms under heterogeneous systems 
must have many practical difficulties and security 
loopholes. The library and literature database, 
teaching database and basic research database 
between universities and scientific research 
institutions can be experimentally connected and 
moderately expanded on this basis. In terms of 
industrial application, the three major operators in 
China take the lead in the construction of information 
infrastructure, so it is suggested that the 
communication industry should be the first to try. 
Fourth, improve security level, avoid data 
disaster. In the block chain technology environment 
to do a good job of network information security 
technology prevention. Blockchain technology has no 
central structure. Rational application can effectively 
improve the data security of the database storage 
nodes of the government, the military and various 
industries, and prevent the data loss caused by the 
catastrophic collapse of a single node. But once the 
system is cracked, and hidden as one of the data 
nodes, it is very likely to occur irreparable 
comprehensive data disaster. Therefore, the 
application of blockchain technology at the same 
time, but also put forward more severe challenges to 
the network security technology. In the short term, it 
is recommended to conduct periodic offline data 
backup in case of accidents. 
Fifth, issue digital RMB and eliminate 
intermediate settlement. From the perspective of 
national economic development, it is suggested that 
the application of block chain technology should be 
actively planned and the international digital RMB 
should be issued as soon as possible. Thus, a foreign 
exchange settlement mechanism without 
intermediaries can be established in the international 
monetary business. This will help to overthrow the 
hegemony of the US dollar and subvert the empire of 
the US dollar, so as to gain certain advantages in the 
subsequent financial wars between China and the US. 
Sixth, the standardization of shared data structure 
has a long way to go and should be started as soon as 
possible. Should stand in the height of the world 
pattern, should as soon as possible for China's 
upcoming blockchain technology upgrade of the 
industry data structure standardization and unified 
planning. The work in this area is urgent and the
