Blockchain-driven physical asset trading system

Blockchain-driven physical asset trading system

Key Glossary

Term Definition Physical assets refer to tangible assets that can be physically touched and owned, such as land, buildings, second-hand goods, etc. Non-fungible token (NFT) A unique and non-interchangeable data unit stored on a blockchain that represents the ownership of digital or physical assets. Blockchain A decentralized distributed ledger that records transactions and tracks assets. Smart contracts Programs stored on a blockchain that are automatically executed when preset conditions are met. Private chain A permissioned blockchain where only authorized participants can join the network and verify transactions. Public key A key used to encrypt messages and can be accessed by anyone. Private key A key used to decrypt messages and can only be accessed by the owner. Transaction block A block of data on the blockchain that contains verified transaction information. Virtual Guarantee Card (VGC) A digital certificate stored on a blockchain that represents a guarantee or guarantee for a specific physical asset. Secondary transactions refer to subsequent transactions of physical assets after the first transaction. Short answer questions

Please explain the difference between physical assets and digital assets and explain how NFTs can be used to bridge the gap between the two.

A: Physical assets are tangible assets that can be touched, such as a house or car, while digital assets are intangible, such as stocks or cryptocurrencies. NFTs bridge the gap between the two by associating a unique digital token with a physical asset, thereby providing digital proof of ownership for the physical asset.

Based on the text provided, describe the three main steps of using blockchain technology to trade physical assets.

A: First, the physical asset is associated with the NFT to create a digital proof of ownership of the asset. Second, the NFT representing the physical asset and the owner information are recorded on the blockchain to ensure transparency and traceability. Finally, when the asset changes hands, the ownership of the NFT is updated on the blockchain to complete the asset transfer.

Explain what is meant by "private chain" and why private chain networks are more suitable for the physical asset trading system described.

A: Private chain refers to a blockchain network that participants need permission to join. Compared with public blockchains, private chains provide higher security and privacy because only authorized parties can access transaction data. This is particularly important for physical asset trading systems because it protects sensitive information such as ownership details and transaction history.

What role does a virtual guarantee card (VGC) play in the proposed system?

Answer: A VGC is a digital credential stored on a blockchain that provides guarantee or warranty information related to a physical asset. It can include product information, warranty details, transaction history, etc., thereby enhancing trust and transparency.

Based on the text provided, list three main advantages of using blockchain technology for physical asset transactions.

Answer: First, blockchain technology can improve transparency because all transactions are recorded on a public and transparent ledger. Second, it can enhance security because the decentralized nature of blockchain makes it difficult to tamper with. Finally, it can simplify the transaction process and reduce the need for intermediaries, thereby reducing costs and improving efficiency.

Explain the relationship between NFTs and physical assets, and explain how changes in NFT ownership are reflected in the transfer of physical assets.

Answer: NFTs are associated with physical assets and represent digital ownership of that asset. When the ownership of an NFT changes, it means that the ownership of the physical asset has also been transferred. This change in ownership is recorded on the blockchain to ensure traceability and transparency.

Based on the text description, how can a second-hand goods trading platform benefit from this system?

A: Second-hand goods trading platforms can improve the transparency and trust of transactions through this system. By associating goods with NFTs, the platform can provide proof of authenticity and origin of goods and reduce the risk of fraud.

Based on the text description, explain the meaning of "on-chain" and explain how physical asset information is "on-chain".

A: "On-chain" refers to the process of recording data on the blockchain. In this system, physical asset information is "on-chain" by associating with NFTs and recording NFT information on the blockchain.

Explain how the system solves the problems of counterfeiting and fraud related to physical assets.

A: The system solves the problems of counterfeiting and fraud by associating physical assets with NFTs and recording NFT information on the blockchain. Because NFTs are unique and immutable, they can ensure the authenticity of assets and prevent the circulation of counterfeits.

Based on the text provided, outline possible future improvements to the system.

A: The system can be further improved in the future, such as developing a more convenient user interface to make it easier for users to understand and use blockchain technology. In addition, it is possible to explore combining the system with other technologies (such as the Internet of Things) to achieve more comprehensive asset management.
