ARPA is a computation network built to deliver privacy-focused tools and services. It works toward a layer-2 privacy approach for blockchain ecosystems and is meant to be compatible with most major blockchains, while still running as its own independent network. ARPA is permissionless, allowing network participants to join on their own and contribute computation resources in exchange for rewards.

The project team outlines three core missions:

ARPA serves as the network’s native cryptocurrency. 

What are ARPA’s key features and how does it work?

To support secure off-chain computation, a proxy smart contract is required to connect ARPA network nodes with the blockchain that receives the request. Afterward, ARPA network nodes process computation tasks based on those smart contracts.

The ARPA network is organized into two layers: protocol and computation. Together, these layers enable the network’s operation. The protocol layer handles supportive duties, such as selecting nodes and acting as a bridge between MPC (Multiparty Computation) nodes and the smart contracts deployed on-chain. The computation layer, as the name implies, performs ARPA’s Multiparty Computation.

Nodes are encouraged to behave properly through economic incentives. In addition, computation results can be checked for correctness even in hostile scenarios, using secret sharing combined with an information-theoretic Message Authentication Code (MAC).

What is noteworthy about ARPA?

Some of ARPA’s notable features include:

What can ARPA be used for?

Developers can leverage the ARPA network to keep dApp data private and build privacy-preserving applications without needing prior cryptography expertise. ARPA’s architecture also supports transferring data without revealing the original data to users during data-at-use. This means data can be monetized without exposing the raw content at any point in the workflow.

ARPA’s technology can be applied to many different scenarios and industries, such as fintech and insurance. For instance, financial organizations can run searches over shared blacklists without disclosing sensitive details. In digital advertising, projects can show ads tailored to user behavior tags without directly accessing private information.
