What is Arpa (ARPA)? How does it work? 


Arpa chain is a secure computational multi-party computing network (ARPA MPC) that aims to solve problems linked to data privacy. ARPA threshold BLS signature network serves as the infrastructure of verifiable Random Number Generator (RNG), secure wallet, cross-chain bridge and decentralized custody across multiple blockchains. Secure Multi-Party Computation allows the ARPA Layer-2 solution to protect and validate transactions while increasing transaction processing times for practically any blockchain network. 

According to ARPA, privacy-preservation with SMPC is more advanced than other methods such as homomorphic encryption (HE), zk-SNARKs, Zero-Knowledge Proofs (ZKPs), and Trusted Execution Environments (TEEs).

Felix Xu and Yemu Xu are the founders of Arpa [ARPA]. Yemu is co-founder of both the APRA Chain and DeFi project it’s based on, the Bella Protocol. He is also a founding partner of ZX Squared Capital and has appeared in Forbes Asia’s 30 Under 30. Amongst his other achievements, he served as Head of Growth for Boro and co-founded Build 312.

Felix is the CEO and co-founder of both the Bella Protocol and the blockchain it is based on, APRA. Before this, Felix served as an investment analyst, later becoming an investor himself. In July of 2021, Felix co-founded the crypto hedge fund ZX Squared Capital.


According to Gemini’s Cryptopedia, Arpa works on a protocol dubbed as  ‘Proof of Correctness’ which works like ‘Proof of Work’. With secure computation on ARPA, Proof of Correctness works by delegating computation only to certain nodes on the network. This delegation process is meant to improve network efficiency, transaction throughput, and code execution security.

Threshold BLS signature scheme is the flagship product of Arpa which acts as a main catalyst in Multi-party Computation on the network. 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. Due to the nature of MPC computing, a Layer-2 architecture is adopted. The main network includes smart contract layer, protocol layer, and computing layer. The security of the network is protected by cryptography design (secret sharing and message authentication code) and economic design (individual account credit system and bidder deposit).


Random Number Generator: Randcast is the random number generator built by Arpa. RNS offers a cryptographically generated random source with superior security and low cost. Developers can use ARPA network to build a privacy dApp without having deep knowledge on cryptography.

Multi-party Computation: ARPA’s Layer-2 scaling platform employs what it calls privacy-preserving Secure Multi-Party Computation (SMPC) for data-sharing between multiple parties in a high-security, cryptographically verifiable manner. ARPA is designed to ensure that on-chain networks never reach their gas limits. This allows the system to dramatically increase transaction times for Layer-1 blockchains.
