(1) In the blockchain system, there is no centralized database, and each node saves all the information of the blockchain, and the nodes have the same rights and obligations; The LWC requires that “consumers and suppliers directly interface”, emphasizing that the individuals conduct fair transactions and reduce transaction costs.(2) The block chain passes the hash value of the block header as the unique identifier of the block, thereby realizing the traceability of the block data; In the LWC, it is emphasized that the information of each bottle of liquor can be traced, fair and transparent, and convenient for consumers to inquire and purchase. (3) Blockchain technology does not require a third-party trust mechanism. It can use blockchain technology to establish a fair and open market mechanism. It can also serve other financial products well. The LWC requires the establishment of an open liquor trading market without the need for middlemen, and will also promote the formation of financial derivatives related to liquor trading. (4) Blockchain system realizes the automation and intelligent execution of contracts through intelligent contracts or “programmable currency”; There will be a large number of intelligent deliveries, transportation, transaction, and storage links in LWC, and a series of intelligent contracts are needed to ensure the automatic execution of LWC transactions. The application model of Blockchain in LWC is shown in Figure 3. Under this model, consumers and suppliers contact each other directly to conduct liquor trading activities. They no longer need middlemen as a trading medium, and consumers can place orders on their own. LWC distributes liquor orders, later delivers liquor to consumers after liquor production and transportation, and intelligent contracts guarantee the automatic execution of each transaction. Liquor information is traceable and transactions are fair and transparent.
