II. Answers

Blockchain technology solves the trust, security and efficiency problems existing in traditional item sharing. The decentralized nature of blockchain allows users to directly participate in the sharing network, improving sharing efficiency; the tamper-proof nature ensures the authenticity and reliability of item information; at the same time, the application of smart contracts also makes transactions more automated and transparent.

The present invention stores the item information of the item to be shared in the blockchain network. By utilizing the tamper-proof and irrevocable characteristics of the blockchain network, the entire process of item sharing can be traced according to the item information, including the source of the item, usage records, maintenance records, etc., thereby ensuring the traceability of the item information.

The item sharing party needs to first register for the service on the item sharing business management platform and submit the user identity information and the item information of the item to be shared. The item sharing business management platform will authenticate the user identity information, and only after the authentication is passed will the item information be stored in the blockchain network.

The item user can send an item query request through the item sharing business management platform, and the platform will query the shared items that meet the conditions from the blockchain network, and transfer the usage rights from the item sharing party to the item user.

When the item is used, the item sharing business management platform will calculate the rental fee according to the payment transaction rules and billing data of the item, and deduct the rental fee from the item user's account, transfer it to the intermediate account, and then transfer it to the item sharing party's account from the intermediate account after the consensus of the blockchain network.

The role of the intermediate account is to serve as a temporary storage account for the rental fee to ensure the security and fairness of the transaction. The introduction of an intermediate account can avoid direct fund transactions between the item sharer and the item user, reducing transaction risks.

The item maintainer can participate in the item management process by sending an item maintenance request to the item sharing business management platform. The platform will send the information of the item to be maintained to the blockchain network for consensus. After the consensus is passed, the item maintainer can maintain the item.

The cost of item maintenance is shared by the user who owns the item and the last user who has the right to use it in proportion, deducted from their accounts, and transferred to the account of the item maintainer.

Compared with the traditional sharing economy model, the method proposed in the present invention has higher efficiency, lower cost, higher security and stronger credibility. At the same time, it also solves the problems of low user participation and high operating costs in the traditional model.

Digital certificates are used to verify the identities of the item sharer and the item user to ensure the authenticity and reliability of the identities of both parties to the transaction; digital signatures are used to ensure the integrity and non-repudiation of transaction information to prevent transaction information from being tampered with.

IV. Glossary

Term Definition Blockchain: A chain data structure that combines data blocks in a sequential manner in chronological order, and a distributed ledger that is cryptographically guaranteed to be tamper-proof and unforgeable. Smart Contract: A computer protocol designed to disseminate, verify or execute contracts in an information-based manner. Consensus Mechanism: An algorithm used to reach consensus in a blockchain network. Common consensus mechanisms include proof of work (PoW) and proof of stake (PoS). Digital Certificate: An electronic document used to prove the identity information of the holder of a digital certificate. Digital Signature: A signature similar to that written on paper, but using electronic verification technology. Item Sharer: A user who shares his or her idle items. Item User: A user who rents shared items. Item Maintainer: A user who maintains damaged shared items. The item sharing business management platform is responsible for managing the platform for the item sharing business, such as registering users, publishing items, renting items, settling fees, etc.
