A Privacy-Preserving Computation Network

 The Dawn of Privacy is Here

ARPA is a Secure Computation Network Compatible With Blockchains

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

Privacy & Security

MPC allows a set of parties to jointly compute a function over their inputs while keeping them private.

The correctness of computation is verifiable even under majority malicious condition

Flexibility & Compatibility

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: Privacy-preserving smart contracts at scale

and data renting

Scalability & Efficiency

Lightning fast performance

for mass adoption via verifiable computation.

Off-chain computation network capable of industrial-level computation and storage


Efficient private smart contract

for DApp developers

Privacy-preserving individual & enterprise data renting

Highly scalable infrastructure

via computational sharding


Secure Multi-party Computation (MPC) allows a set of parties to jointly compute a function over their inputs while keeping them private. The correctness of computation is verifiable even under majority malicious condition using secret sharing and information theoretic Message Authentication Code (MAC)


Fintech & Insurance

Credit Anti-fraud 

Financial institutions can search shared blacklists or perform joint risk analysis for borrowers without disclosing each party's private information

Secure Risk Analytics

Financial calculation agent can run risk analytics on client's encrypted data. Client's data is 100% invisible to agent

Digital Advertising

Precision Ads Display

Advertisers can display ads to target customers for relevant products based

on massive user behavior tags, without breaching user privacy

Profiling Engine

Secure data matching of identities across multiple industries and organizations for well-rounded user profile

Personal Data Wallet

Data Wallet

Users manage all personal sensitive data, define data policy

and conveniently authorize to service providers in encrypted form

Secure Monetization

Users can 'rent out' data to advertiser for product preference analysis, free of personal data leakage

ARPA is a global research & development entrepreneurial team. Every team member has studied and worked overseas. We graduated from top tier institutions like Tsinghua, CMU, UMich, NYU, GWU, UC Berkeley, and UI, and worked at Google, Uber, Amazon, CircleUp, Fosun, MIT Lab, and National Cryptographic Labs. Research-wise, we work closely with professors from NYU, Zhejiang University, and Hong Kong Polytechnic to discuss the cutting edge academic achievements of sMPC and explore its applications. Blockchain-wise, our advisors include former Blockstream Product Director, the world's first side-chain core R&D member, founder of TechCrunch, and investors from top cryptocurrency funds.
