Exchange ARPA Chain

Arpa Chain is a privacy-preserving computation network compatible with blockchains. It is a blockchain agnostic layer-2 solution that can be used widely. Arpa Cryptographically enables private smart contracts providing excellent data-at-use privacy protection and scalable computational sharding. Proxy smart contracts are used as a bridge to link the blockchain and the computational network. 

Arpa Chain was founded in April 2018 with the goal to separate data utility from ownership and enable the renting of data. Arpa’s MPC protocol allows collaborative analyzing data and extracting data synergies for the multiple entities while protecting data security. 

The developers can build dApps preserving privacy on compatible blockchains, for example, creating a credit anti-fraud, secure data wallets, and key management systems, or using it for AI model training. The main spheres of application are Fintech&Insurance, digital advertising, personal data wallets, and Healthcare (for example, smart diagnosis systems). Arpa collaborates with numerous organizations and technology companies such as Chainlink, ISO, JD.com, Sinochem Group, CAICT, Elrond. Recently it also partnered with Travala to allow Arpa token holders to book travel products in over 230 countries. 

Arpa is a utility Ethereum token powering the network and it’s used as a measure of payment for data, computation, model usage fee, a security deposit, and also for the governance of the project. The total supply of the tokens is 1.5 billion with 982 million being in the current circulation. Starting from August 2019, Arpa team buys 0.5% of the initial total supply each month and burns them.
