Privacy projectShutter Network: Threshold encrypted mempool. Technology: garbled-circuit MPC.
Shutter encrypts transactions until they are already ordered, using threshold cryptography and distributed key generation so a committee can only decrypt after the block is fixed. That closes front-running at the protocol level rather than policing it afterwards, and the same mechanism protects voting from bribery and sealed-bid auctions from leaking. It is live and integrated with real chains and governance systems. The guarantee rests on the keyper set staying honest and available, which is the standing assumption in threshold schemes.

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.
