the MPC network as co-processor (2025, Solana orbit). computations run inside MXEs — multiparty execution environments where each node holds only secret shares of the inputs, protocols tolerate dishonest majorities, and the composed result returns on-chain. shared private state becomes a service any chain can call: dark pools, sealed auctions, private AI inference across parties that trust no one in particular
the lesson: MPC graduated from key ceremonies to general computation — many parties compute, no one holds the input. the trust-distribution vertex of the privacy trilateral standing alone in production, the role mudra's threshold schemes play inside soft3
