Short answer questions

Blockchain is an application model that combines computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism and encryption algorithm. Its core features include decentralization, immutability and autonomy.

Blockchain technology can be used to record and verify customer identity information, as well as track suspicious transactions, thereby improving the efficiency and accuracy of anti-money laundering work and helping financial institutions meet regulatory requirements.

"Know Your Customer" (KYC) refers to the process of identifying and verifying the identity of a customer when establishing a business relationship or conducting a transaction with a customer. KYC is the foundation of anti-money laundering because it helps financial institutions assess customer risks and prevent money laundering activities.

In the existing KYC verification system, sales institutions usually have basic information about customers, but due to the requirements of data privacy protection, this information cannot be directly passed to financial institutions. This makes it difficult for financial institutions to conduct KYC verification independently and meet regulatory requirements.

A privacy computing platform refers to a platform that calculates and analyzes data without leaking the original data. It can achieve data sharing and utilization while protecting data privacy through technologies such as encryption and secure multi-party computing.

A smart contract is a piece of code stored on the blockchain that can automatically execute pre-defined rules. In the information sharing method, smart contracts can be used to define data sharing rules, verify the identities of participants, trigger data transmission and other operations, thereby achieving automated and trusted data sharing.

TEE is a trust execution environment based on CPU hardware security extensions that is completely isolated from the outside world. It can provide a safe and reliable execution environment for blockchain transactions to ensure that transaction data is not stolen or tampered with during processing.

DID is a blockchain-based digital identity that can be used to uniquely identify an entity. It can help participants prove their identities and exchange reliable data without leaking sensitive information.

VC is a digital certificate issued by a DID subject to prove that a subject has specific attributes or qualifications. In the information sharing method, VC can be used to prove the authenticity of KYC verification results and improve the reliability and credibility of information.

This information sharing method uses the privacy computing platform and blockchain technology to achieve data sharing in a safe and controllable environment, so that institutions that do not have anti-money laundering capabilities can also obtain users' KYC results, thereby meeting regulatory requirements and improving the industry's overall KYC verification capabilities.
