About ARPA
Website丨Explorer丨White paper
ARPA Chain constructed an easy-to-use multi-party computing network (ARPA MPC), aiming to solving the problem of data privacy. Some potential use cases would be:
· Developers can use ARPA network to build a privacy dApp without having deep knowledge on cryptography.
· The providers of data can 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.
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 massage authentication code) and economic design (individual account credit system and bidder deposit). ARPA token can be used as deposit of running a computing node and rewards of computing.
What is Automated Market Making (AMM)?
Automated market making (AMM) can calculate the buying and selling price according to the formula, so as to provide continuous quotation for the market. CoinEx combines AMM with the order book, which means the liquidity pool will be automatically converted into the order book. With the "constant product market maker formula" algorithm in AMM, no matter how large the order book is or how small the liquidity pool is, firm liquidity provision to the market can be guaranteed.
