Table 1

Differences between blockchain and traditional technology.

Taxonomy	Traditional technical features	Traditional technical description	Blockchain features	Blockchain description
Recording method	Single center control	Single node full authority record and maintenance	Multicenter control	Multicenter consensus confirmation record, common maintenance
Transfer method	Single center control	Single central node full supervision and operation	Multicenter control	Multicenter collective supervision, mutual supervision and checks and balances
Data consistency	External presentation of a single data channel	Single data inventory, no consistency risk	Data consistency through multicenter consensus	Will face certain systemic attacks
Data security	Single center is solely responsible, single point of risk	A single center is responsible for the security endorsement of the entire system; as long as a single node is breached, there will be systemic risks	Multicenter coordination, multiparty secure computing	Multiple centers back up their data, verify data with each other, and check and balance each other, so there is no need to worry about data loss caused by a single center
