Profile
ARPA is a layer two protocol utilizing Multi Party Computation (MPC) for analyzing sensitive data. When deployed on a layer one, it allows the sharing and analysis of sensitive data without compromising the sensitive nature of the data itself. This is especially important for any layer one where all transactions are public. The ARPA network is a layer two solution that performs secure computation on sensitive data, a process known as Multi Party Computation (MPC). Typically a proxy smart contract is triggered on a layer one blockchain like Ethereum by anyone looking to request this kind of MPC and these requests require a fee paid in ARPA. The types of calculations performed can include things like statistical analysis and advanced arithmetic to Value at Risk and matrix multiplication. Next, there is a set of computation nodes in the ARPA network that bid on the right to provide computing power by paying a security deposit in ARPA. Nodes are randomly selected via a decentralized random function based on history of performance, success rate, latency, etc. The selected nodes then coordinate together to perform ARPA MPC by Secret Sharing and evaluating a compiled function in the form of executable binary. Values are exchanged between parties using a securely encrypted channel and after completion, computation proofs called Message Authentication Codes (MAC) are produced and passed back to the proxy smart contract at the layer one level. MACs are information-theoretic secure so that the computation can be verified at the layer one level. If the MAC check is passed then the data provider is compensated with a data usage fee in ARPA while the predicating nodes divide up and receive the computation fee.
