The Chinese Academy of Information and Communications(CAICT): Blockchain Needs to be Integrated with Privacy-Preserving Computation

On October 29th, 2020, the Chengdu Global Innovation and Entrepreneurship Fair — 1st International Blockchain Industry Expo was hosted in Western China International Expo City. The conference was jointly organized by Chengdu Municipal People’s Government, China Academy of Information and Communications Technology (hereinafter referred to as “CAICT”), and other related organizations.

The fair’s theme was “Linking Ecology, Enabling a New Future,” focusing on the current status and trends of blockchain technology development and linking resources in the blockchain industry. Additionally, the fair also considered how to create an ecology for the development of the blockchain industry, how blockchain technology can play a greater role in building our cyberspace strength, the development of the digital economy, and the potential of “blockchain +.”

At the opening ceremony, the deputy chief engineer of CAICT, Heyuan Xu, released the “Blockchain Industry Top 10 Trends(2020)” list, which provides an in-depth interpretation of the important trends that emerged in the development of China’s blockchain industry in 2020. The trends are as follows:

  • Long-term improvement in the blockchain industry and widespread recognition of blockchain core values.

With the level of awareness of blockchain increasing throughout society, enterprises are beginning to recognize blockchain’s value. However, enterprises have concerns about data privacy after uploading the data on-chain, which has become one of the most significant obstacles for enterprises to adopt blockchain. Blockchain needs to be integrated with privacy-preserving computing applications to ensure data credibility, with later developments fusing data availability with invisibility. This will eliminate the privacy concerns of enterprises uploading the data on-chain, which is conducive to the in-depth development of industrial applications.

ARPA is a leader in secure multi-party computing (MPC) technology. With MPC, operations can be performed on encrypted data, making the data available for analysis while keeping it invisible and secure. ARPA helps different organizations conduct data sharing, model training, and prediction while meeting user privacy protection requirements, data security policies, and regulations. Shared learning technology has been applied to various business scenarios such as credit, risk control, insurance, and government affairs.

About ARPA

ARPA is a blockchain-based solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership, and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code (MAC).

Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include: credit anti-fraud, secure data wallet, precision marketing, joint AI model training, key management systems, etc. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.

Team members have worked at leading institutions such as Google, Amazon, Huawei, Fosun, Tsinghua University, Fidelity Investments. ARPA is currently assisting the China Academy of Information and Communications Technology in setting the national standard for secure multi-party computation. ARPA is a corporate member of MPC Alliance and IEEE and is in partnership with fortune 500 companies to implement proof-of-concepts and MPC products. In 2019, ARPA was named as the Top 10 most innovative blockchain companies in China by China Enterprise News and China Software Industry Association.
