Project Background:

The name ARPA comes from the APRAnet network program developed by the United States Department of Defense in 1969. APRAnet was the predecessor of the TCP/IP protocol, and is considered a forerunner of the modern internet.

Q: What was the original intention of launching the ARPA project? Why did you look in this direction?

Felix: This is an interesting question. I gave up my investor identity to work as an entrepreneur, mainly because of the long-term development of the security data exchange market. My investment experience gives me the opportunity to learn from many excellent entrepreneurs. Investment and post-investment management gave me a deep understanding of not only the industry at large, but also the daily management of enterprises.

Q: Could you describe the technical highlights of ARPA? What have you accomplished?

Jiang: The secure multi-party computing (MPC) technology and the ARPA cryptographic protocol of the ARPA privacy computing network are our unique advantages. We can ultimately realize the separation in data of the right to use and the right of use, and directly calculate results on multi-source and heterogeneous ciphertext data. Computational operations do not need to decrypt the original data, as technical barriers are extremely high.

Q: How is ARPA progressing? Can you describe in detail the current development efforts, market expansion plans, expected applications, and when will they be commercially available?

Jiang: The ARPA project was launched in April 2018. At present, the test network based on safe multi-party computing (MPC) has been released ahead of the roadmap. The user can publish the calculation request to the ARPA security computing network through an Ethereum smart contract. The privacy calculation is done by the ARPA node, and many kinds of MPC computing functions are supported at present.

“At present, we are the only project which can meet the requirements of enterprise-level computing MPC.”

Q: Can you compare the differences between star projects in the current market, which focus on privacy solutions? For example, PlatON?

Felix: At present, there are few privacy computing projects based on cryptography for competition. We are the only project in the world that can support multi-party MPC computing in the test network phase. Other MPC-related projects include: Keep Network, which uses secret sharing for storage; PlatON, which supports two-way secure computing (2PC). In the field of non-cryptographic computing, security hardware projects such as SGX have advantages of Enigma and Oasis Labs — speed, but centralized — and there are some engineering problems as well.

Q: ARPA’s entry point is enterprise-class privacy data sharing, and there are many projects in similar directions on the market, such as GXC. How does ARPA differ in this regard? What are the enterprise partnerships?

Felix: The key to privacy data sharing is to make the data “available but not visible”. At present, many projects in the market claim to have data sharing, but actually do data transactions. Even if the transaction process is encrypted/co-chained, once the data is decrypted by the user, it can be copied and shared off-blockchain, and the blockchain itself, alone, cannot solve the data privacy problem.

“The IEO model is not new in South Korea.”

Q: How did ARPA become the first China-Korean joint IEO? On what trading platform will you conduct the IEO and what is the relationship between ARPA and the platform? Why do you choose to open both platforms in China and South Korea at the same time?

Felix: We think China and South Korea are the two most important crypto markets, and our partners are BISS and Tokenman. BISS is the world’s first crypto-to-crypto plus crypto-to-securities exchange, and Tokenman is backed by the Bitman community, which is South Korea’s largest and oldest blockchain community. We will invite more than 450,000 people who hope to be more deeply involved in the crypto world on Naver (a South Korean version of Baidu). In addition, we will also cooperate with the leading public chains in South Korea, and more project commercialization and business developments will be conducted in the future in South Korea.

Q: What do you think of the current IEO trend?

Jiang: From an industry point of view, rapid development needs financial support, and the growth of good projects will bring high returns to investors. Unlike previous ICOs, IEOs helped investors screen projects through exchanges, eliminating a large number of unqualified projects and scams — which means a lot to investors looking to protect themselves.

Q: What are ARPA’s enterprise partners?

Felix: Information of our partners can be seen on our official website Currently we have strategic cooperation with more than 20 large enterprises at home and abroad. With regard to our team, we have 10 full-time team members and 5 scientific researchers, who all have long-term overseas working experience in big enterprises. The team has outstanding scientific research, engineering, and BD capabilities, which forms the core of our competitiveness.

Q: How does ARPA make profits?

Jiang: We will make a profit by providing technical solutions for enterprises, building secure data sharing platforms, providing secure data analysis products, and so on.

Q: How do ordinary users participate in ARPA? Could one run nodes, for instance?

Jiang: In the future, our MPC network will be accessible for participants, and provide enforceable files, where users can download and run nodes.
