MPC Development Library

Our MPC Library allows multiple parties to jointly compute a function over their private inputs, without revealing those inputs to each other or to any external observer. This can be useful for maintaining the privacy and confidentiality of sensitive data, such as personal or financial information.

Key Advantages of MPC

We provide MPC research and development services.

Secure

MPC protocols are built to withstand attacks like eavesdropping, tampering, and denial of service, making them ideal for securing sensitive data.

Distributed

MPC enables computations between parties that don’t trust or want to share data with each other, making it ideal for systems with conflicting interests.

Trustless

MPC protocols can be efficient and scalable, enabling large-scale computations without relying on a central authority or trusted third party.

Flexible

MPC is versatile and can be used in various scenarios, like distributed systems, cloud computing and IoT, making it a flexible technology.

FAQs on Multi-Party Computation

What is Multi-Party Computation (MPC) and how does it work?

Multi-Party Computation (MPC) is a cryptographic protocol that enables multiple parties to collaboratively compute a function without revealing their individual inputs. MPC ensures privacy by encrypting sensitive data and dividing it across participants, who work together to achieve the final result without exposing any private information.

What are the key use cases for CoinFabrik’s MPC library?

CoinFabrik’s MPC library is designed for various secure computing use cases, including:

Secure key management: Distributing cryptographic key generation and signing operations among multiple parties, ensuring no single party holds the complete key.
Threshold signatures: Enabling secure operations, such as cryptocurrency transactions or document signing, that require consensus from a specific number of participants.
Privacy-preserving data sharing: Allowing organizations to collaborate on computations without exposing sensitive data to any single party.

How does MPC enhance security compared to traditional cryptographic methods?

Unlike traditional cryptographic solutions that rely on centralized storage of sensitive keys or data, MPC decentralizes computations and key management across multiple parties. This reduces the risk of data breaches or hacking, as no single entity holds the entire key or data, providing an additional layer of security.

What industries can benefit from using CoinFabrik’s MPC library?

Industries that can benefit from MPC technology include:

Finance and Crypto: For secure key management and transaction signing without exposing private keys.
Healthcare: Protecting sensitive medical data while enabling secure collaboration between research institutions.
Insurance: Safeguarding customer data during multi-party claims processing.
Government and defense: Facilitating secure voting systems and confidential data sharing across departments.

Why should you choose CoinFabrik’s MPC library?
