## Secure Multiparty Computation

Secure Multiparty Computation is a subfield of cryptography that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. In the context of financial protocols, this allows for the collaborative management of assets or order matching without any single party having access to the raw data.

It is a powerful tool for privacy-preserving finance, as it enables secure and private interactions between distrusting parties. By splitting data into encrypted shares, the system ensures that no one can reconstruct the original information without the participation of the required number of parties.

This technology is used to build secure decentralized sequencers and private matching engines. It provides a robust foundation for maintaining confidentiality in a transparent environment.

Secure multiparty computation is essential for protecting sensitive financial logic from compromise.
