ARPA Official Whitepaper & MPC Demo Now Available!
A privacy-persevering computation network. The Dawn of privacy is here! (https://arpachain.io/)
Dear ARPA community,
We are more than thrilled to announce that the official whitepaper and MPC demo have been made available to the public! Thank you all for your patience, warm support and interest in what we do to make privacy prevail and to take blockchain mainstream.
We first released the brief version of whitepaer, or litepaper, on October 2nd, and have received tremendous inquiries and interests. As such, we are releasing our official whitepaper (version 0.7) today.
This document fully illustrates everything you need to know about our project: why secure computation network, what ARPA can offer, background knowledge about MPC, system design and implementation, detailed explanation of our multiparty computation protocol, and implications and applications of the real world.
You can access our whitepaper here. Also, we made a special demo explaining privacy-preserving data sharing across multiple parties on YouTube. We can’t wait to hear from you! Please send us any further questions or inquiries to about@arpachain.io.

Whitepaper Summary
We propose a secure, privacy-preserving computation solution for blockchain networks. The correctness of computation is verifiable even under malicious majority condition using information-theoretic Message Authentication Code (MAC), and the privacy is preserved using Secret-Sharing. With state-of-the-art multiparty computation protocol and a layer 2 solution, our privacy-preserving computation guarantees data security on blockchain cryptographically, while reducing the heavy-lifting computation job to a few nodes.
This breakthrough has several implications on the future of decentralized networks:
- Secure computation can be used to support Private Smart Contracts, where consensus is reached without exposing the information in the public contract.
- It enables data to be shared and used in trustless network, without disclosing the raw data during data-at-use, where data ownership and data usage is safely separated.
- Computation and verification processes are separated, which can be perceived as computational sharding, this effectively makes the transaction processing speed linear to the number of participating nodes.
Our objective is to deploy our secure computation network as a layer 2 solution to any blockchain system. Smart Contracts will be used as bridge to link the blockchain and computation networks. Additionally, they will be used as verifier to ensure that outsourced computation is completed correctly. In order to achieve this, we first develop a general MPC network with advanced features, such as:
- Secure Computation,
- Off-chain Computation,
- Verifiable Computation,
- Support dApps’ needs like privacy-preserving data exchange.
MPC Demo
Below is the MPC demo, brought to you by our co-founders, Jiang and Felix. This is a case where trustless parties (banks) use ARPA network to compute the debt-to-income ratio for a shared customer, while keeping information completely secret.
ABOUT ARPA
ARPA is the privacy-preserving solution for blockchain. ARPA’s secure computation network enables 1) private smart contract, 2) unprecedented privacy protection for data-at-use, 3) scalable computational sharding via Verifiable Computation.
ARPA enables numerous use cases including secure data renting/exchange, secure cloud computation, identity protection, computation outsourcing, etc. These cases are applicable to AI, banking, insurance, healthcare, IoT, government etc.
