Q: How does WaltonChain plan to prevent the RFID chips from genuine products being removed and placed into counterfeit goods? While I understand this will stop the production of counterfeit goods from counterfeit factories, I do not understand how this will prevent chips from genuine products being placed onto the exact same counterfeit item. A: In the prevention of RFID IC (RFID IC = Radio Frequency Identification Integrated Chips, i.e., WTC's bread and butter) removal, Waltonchain currently has a corresponding solution for different industry applications.
In the clothing industry, we put RFID tags with washing marks on a single product brand. When RFID labels combined with product transfer among production, logistics, sales and other aspects of circulation, forgers cannot get washing mark removed and move the RFID tag to the other fake and shoddy goods. For the food, retail and other related industries, Waltonchain developed a fragile, anti transfer RFID tag, which is attached to the RFID tag (I think they meant that the RFID tag is attached to the product). If the forger wants to remove the label, it must be removed with stress and it will destroy the product. Our products will destroy the label line under the condition of stress removal, which will lead to the failure of the RFID tag, and the imitations can not be used on shoddy products. We developed the combination of RFID tags and product, e.g., label technology combined with different clothing materials. RFID label and clothing products are a perfect combination, and making use of the RFID tag has reliability and stability at the same time while being subtle. The tag IC will also store the characteristics of the corresponding items and status information hash value, and if removed to other products, will lead to it being unable to synchronize data on the chain. This ensures that labels and the physical products have one-to-one correspondence.
Q: How will WaltonChain ensure the RFID chips on production lines cannot be copied? Do you use specific production line readers which will only read Walton RFID? A: The RFID tag IC will be written into the world's only EPC code (EPC = Electronic Product Code, a unique number that identifies a specific item in the supply chain) when it leaves the factory, and at the same time, our RFID tag IC will integrate the real random number generator, which will generate a unique address through encryption logic. The Walton chain of RFID does not require special production lines.
Q: If the item is authenticated with a Walton RFID, how does Walton plan for customers to check said authenticity?
A: The customers will use can query the appropriate data by using Walton chain, as all the data is transparent. Because Walton Chain is a blockchain, customers can see the timeline of the product from source to destination. (hint hint this is why WTC is a big deal!)
Q: If the RFID is on the packaging of a box, how will Walton plan to prevent the contents of the boxed being replaced? With the counterfeit market being so lucrative, people will go to extreme lengths. A: The fragile anti-transfer label developed by our Walton chain team can prevent the replacement of the label from the genuine case. We will place the fragile anti transfer label location where the package may be opened, ensuring that the RFID tag is fully bound to physical assets when applied. The use of the product packaging before demolition will allow consumers query the product. If the replacement units in the packaging box undergo stress, it will enable the RFID tag failure, leading to product information not being queried again. This solution can also guarantee the product will not be replaced.
Q: With the RFID chips being issues from a WaltonChain database, what would happen if the issuing database was compromised? Would the issueing database be entered into the blockchain? A: The question is not very clear. What do you want to ask?. Waltonchain is based on block chaining, designed to be decentralized, distributed accounting, and all upper chain data are confirmed by more than half of the nodes. The data on the chain can not be tampered with. (This is why WTC is a superior model to existing RFID industry solutions --- I think they should emphasize this more: They can have a shared ledger which is immune to compromising attacks and will facilitate better supply chain interoperability)
Q: Monitor has mentioned that the code base will be public facing, are there limits to what will be made public? Are there any security risks to having your code base public? A: We have plans to open the Walton chain code, but we must open the relevant code at the right time after we have completed full reliability and security tests.
Q: Would Walton Chain consider providing pictures or other clear information about the RFID hardware? A: Walton chain IC engineers are working hard on related RFID IC and reader IC research and development. Lately they have been working on design and simulation work. The RFID system based on the Walton mother chain is being debugged. (Very cool, as it's clear to me they're going to be prototyping and going to market fast. Just look how many of the team members have a background or are part of the Shenzhen ecosystem [China's silicon valley known for being able to develop and prototype in the same day])
