Privacy projectArcium: Confidential compute network. Technology: garbled-circuit MPC.
Arcium is the most substantial MPC effort on Solana, running an encrypted execution engine that handles hundreds of thousands of confidential computations a day and already carries third-party products such as the Umbra wallet. The design gives builders a choice of trust model rather than one setting for everyone: a stronger mode that halts rather than continue under a dishonest majority, and a faster mode tuned for honest-but-curious operators. The network is in mainnet alpha on an operator set Arcium permissions, and the team arrived at this design as a second act, after winding down its earlier protocol, Elusiv, and rebuilding around encrypted computation.

What is garbled-circuit mpc?
Several parties jointly evaluate a function over encrypted inputs using garbled circuits and secret sharing, so no single party ever holds the plaintext.
How it compares with the other approaches on latency, trust assumptions and fit is set out, with sources, in the technology taxonomy.
