Arcium enables private, verifiable computation for Solana apps using MPC and ARX-secured network operators.

Arcium（ARX） is a Solana-native confidential-computing network, described by the project as a “Confidential Supercomputer” for Web3. It uses secure multi-party computation, MPC eXecution Environments and decentralized Arx nodes to let applications compute over encrypted data without exposing the underlying inputs. ARX is the network token for securing compute supply through staking, governance and protocol alignment, while computation fees themselves are paid in the host chain’s native asset, such as SOL on Solana.
