A Blockchain-Based Privacy-Preserving Computation Network.
Share this article
Arpa envisions to be a privacy-preserving computation network by leveraging Multi-Party Computation (MPC).
MPC hinges on separating data utility from ownership, and thus enabling data renting. Subsequently it is possible for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party's data input private and secure. ARPA Chain allows secret sharing of private data, and the correctness of computation is verifiable via a Message Authentication Code.
Arpa is a blockchain-agnostic layer-2 solution that is widely usable. Proxy smart-contracts are used as a bridge to link the blockchain and secure communication network.
The ARPA token can be used to computation cost, data and model usage fee, make a security deposit and participate in community governance.
1. What is ARPA Chain (ARPA)?
ARPA is a blockchain-based layer 2 solution for privacy-preserving computation, enabled by cryptographic Multi-Party Computation ("MPC").
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 analyze data and extract data synergies, while keeping each party's data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code.
The use cases of the ARPA token include computation cost, data and model usage fee, security deposit, community governance, etc. The ARPA token currently runs on the Ethereum network.
Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include credit anti-fraud, secure data wallet, precision marketing, joint AI model training, or key management systems. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.
2. Economics and supply
The supply distribution is as follows:
Private Sale 1: it was conducted in June 2018 for 100,000,000 ARPA at an average rate of $0.02 per token, and raised a total of 1,370 ETH and 1,383,500 USDT（$2.00MM), for 5% of the total token supply.
Private Sale 2: it was conducted in December 2018 for 100,000,000 ARPA at an average rate of $0.02 per token, and raised a total of 2,000,000 USDT, for 5% of the total token supply.
Public Sale: it was conducted through an IEO with BISS on 25 April 2019 for 140,000,000 ARPA at an average rate of $0.018, and raised a total of 2,520,000 USDT, selling 7% of the total token supply.
ARPA token distribution (%)
The following chart represents the number and breakdown of all ARPA that are to be released into circulation on a monthly basis. For every month from August 2019 to February 2021, the ARPA team will repurchase from the open market and burn 0.5% (10,000,000 ARPA) of the initial total ARPA token supply.

3. ARPA's activity and community overview
3.1 Development activity
ARPA migrated its repository from Github to Gitlab.
3.2 On-chain activity
3.3 Social and community data
ARPA will initially focus on business development and community building in Asia and Europe. The focus of community growth will gradually expand to other markets as the project gains popularity.
Current community growth strategies of ARPA include:
International community bounty programs to spur user growth on social media & community.
Global supernode program, local community builder and media partner program to promote ARPA globally.
Host & participate in blockchain and cryptography related conferences, workshops, and meetups to engage with potential users and supporters.
Monthly meetups in China, Korea and South East Asia.
Multi-language, bi-weekly technical & community updates.
Future community growth strategies of ARPA after Mainnet launch include:
Host global meetups, hackathons, and conferences on topics such as blockchain, cryptography, privacy and privacy-preserving computation.
Partnerships with top local enterprises and tech-focused communities on implementation of privacy-preserving computation.
Top media coverage and partnership with research institutions, policy makers and think tanks.
