Arcium Confidential Computing

MAGMA Shield integrates Arcium to provide confidential compute over sensitive conviction data. Arcium's MPC (Multi-Party Computation) network lets Shield process position sizes, oracle inputs, and claim assessments without exposing them to any single party — including MAGMA itself.

Integration status

Arcium integration points are marked // ARCIUM_STUB in the on-chain program at the back_shield and claim_* instructions. On devnet, amount_lamports is stored in plaintext. Full Arcium SDK integration is part of the V2 mainnet launch scope. See Shield Technical Specification.

Confidential backing​

When a backer enables Arcium mode:

  • Their backing amount is encrypted on-chain via Arcium MPC.
  • Only the backer and the oracle decryption key can read the position size.
  • MAGMA's backend cannot see individual position sizes.
  • Institutional participants can back without revealing size or direction.

This enables participation from funds, DAOs, and protocols that cannot disclose position sizes for compliance or competitive reasons.

Private oracle inputs​

Security researchers who contribute exploit intelligence to the AI Oracle can do so without revealing:

  • Their methodology.
  • The specific evidence they hold.
  • Their identity.

Oracle resolution runs on encrypted inputs. The verdict is verifiable without the inputs being exposed.

Encrypted claim assessment​

On FALSE resolution (exploit confirmed), the forensic claim assessment runs inside an Arcium Trusted Execution Environment (TEE):

  • Inputs: on-chain transaction data, oracle feeds, researcher submissions.
  • Processing: inside the Arcium TEE.
  • Output: a cryptographically signed verdict.
  • Verifiable: anyone can verify the verdict was correctly computed without seeing the inputs.
