        The "networking Conference - Zhejiang blockchain project matchmaking conference" was held in the Jingxing Hall of the Wuzhen Internet Conference. After multiple rounds of certification and confirmation, 33 high-quality blockchain projects including complex beauty, Qulian technology, xunlian technology, Yunxiang blockchain, time forest technology, Huaxin blockchain, Yibei technology and Shanlin technology were shortlisted. Collection, prepayment, warehouse receipt mortgage, points, exchange, etc.  the use of blockchain technology can effectively solve the information island phenomenon in the operation process of the traditional supply chain, and make the information exchange and sharing among the node enterprises and institutions.  blockchain can also help SMEs accumulate credit data and reduce financing costs.

         3. Data storage certificate:  the public key addresses of the asset side and the fund side are bound to the Ca and recorded on the blockchain, which can be used as identity authentication and asset proof;  the block hash containing all transactions is backed up on multiple blockchains after being signed by the third-party authentication center, which can easily realize judicial authentication in case of disputes;  bill information, participant information and transaction information are recorded on the blockchain. All data cannot be tampered with. Transaction line, supply chain - Bill Financing: scheme process. The statistics and maintenance cost of accounts receivable and other data are high. 2. Each financing application of the supply enterprise shall be established under the real trade background, and each transaction record of the core enterprise, fund provider and supply enterprise shall not be forged or tampered with.
        3. Trade contracts and other documents shall be digitally signed and kept to ensure that they cannot be tampered with or forged. 4. Online asset matching is automatically executed and settled. The records cannot be tampered with. Ensure that there is no over credit or under credit. 2. Core enterprises apply for issuing credit tokens of the same amount according to the credit line of financial institutions, so as to facilitate the statistics of their own guarantee amount and usage. 3. Each financing application of upstream and downstream enterprises needs to be exchanged with corresponding credit tokens to ensure that there will be no confusion in internal management and random lending. 4. The information related to the loan record is written into the blockchain and can be used as a deposit certificate for the settlement of future default disputes. 5. After the repayment of upstream and downstream enterprises, the credit line will be restored through credit tokens, and the settlement statistics will be carried out step by step.
        6. The credit token can be set with a valid period to facilitate the adjustment of the enterprise credit line after a period of time. The advantage is that once the assets are issued on the blockchain, the subsequent circulation links can not depend on the issuer's system. The circulation of assets is changed from single center control to social communication. Any channel with resources can become a catalyst for the circulation of assets. Therefore, the blockchain can greatly improve the circulation efficiency of digital assets and truly achieve the effect of "multi-party issuance and free circulation".

Quality control: the detailed records such as the production process and logistics path of goods can be tracked through the blockchain to ensure that the quality of goods is controllable. 5. Settlement and clearing: users who ultimately own commodity tokens can sign for commodities, and the settlement and clearing are clearly recorded on the blockchain. On the registration platform, any merchant can simply and conveniently apply to the API interface and have the right to issue its own prepaid card. The platform can also obtain real and reliable consumption big data. 2. Independent operation of merchants: each merchant or chain merchant intervenes with an independent app node; It can directly receive cash or transfer advance payment without any third party; It can issue commodity tokens and package tokens corresponding to prepaid cards and various activity tokens; You can view and count the consumption records of consumers in our store.
        3. Prepaid card wallet app: consumers do not need to handle multiple prepaid cards. They only need one app to handle prepaid cards at the desired merchants on the platform. They only need a smart phone to go to different merchants and pay the corresponding commodity service tokens; At the same time, you can view the recharge records and consumption records of various prepaid cards at any time and anywhere. You can also transfer unnecessary prepaid cards through app, or give them to friends and relatives to experience merchants. Determine the identity of the contracting party. 2.

Different points are not convenient for the query and use of points, resulting in points being like chicken ribs and not playing the role of user diversion.
        2. Points cannot be transferred. According to statistics, the current exchange rate of points in China is only 12%, and nearly 90% of users have not been properly guided to spend. 3. The issuance of points is not transparent. The traditional points issuance is based on the database, and the data maintenance cost is high. However, the points of small enterprises have the risk of tampering and forging, which makes the public credibility insufficient.
