Xu graduated with Finance, and Information Systems degrees from New York University, which is known for its Computer Science and AI research. For the past 6 years, Felix has been working on venture capital investment in Fintech, big data and AI startups. Most recently he led blockchain sector research and early-stage investment at Fosun Group, one of the largest conglomerates in China.


According to a recent interview, Xu’s vision is as follows:

“I have always been a believer of freedom. Fascinated by Bitcoin and Ethereum’s vision, in early 2018, I decided to create a new blockchain protocol that focuses on data privacy.

From the very beginning, ARPA’s mission has been to separate data utility from ownership, thus enabling data renting. On this journey, our team has contributed to the development of Multi-Party Computation (MPC), which is arguably among the most cutting-edge cryptographic algorithms to date.

ARPA’s MPC protocol paves the way for multiple entities to collaboratively analyze data and extract synergies while keeping each party’s data input private and secure. Over the years, we helped set up the international standard of privacy-preserving computation, namely IEEE, and have raised substantial awareness on individual data privacy.

Moreover, we found that cryptographic algorithms can have many promising by-products, such as the verifiable random number generator. Now, we no longer limit ourselves to privacy, but explore the full spectrum of cryptographic applications in blockchain.”


Building Arpa

In fact, ARPA is a blockchain-based layer 2 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 analyse data and extract data synergies, while keeping each party’s data input private and secure.

As Xu explains:

“We propose a blockchain-based secure computation network of Multi-party Computation (MPC). ARPA cryptographically enables private smart contract, unprecedented data-at-use privacy protection, as well as scalable computational sharding ARPA network is flexible, easy-to-use, and compatible with existing blockchains such as Ethereum and EOS. Let’s rethink blockchain for the real world”.
