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.

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.
