Collaboration Between Mutually Distrustful Parties Through MPC: A New Era of Trust in Blockchain | by Crypto vest D T F | Apr, 2024

In a world where trust is often elusive, the challenge of fostering collaboration among mutually distrustful parties has never been more significant. Whether in business, technology, or governance, the ability to work together while maintaining privacy and security is crucial. Enter Multiparty Computation (MPC), a groundbreaking technology that enables collaboration without compromising sensitive information.

## The Importance of Trust in Collaboration

Trust is the foundation of any successful relationship. It is built over time through a pattern of reliability, shared goals, and a balance between vulnerability and security. However, trust can be fragile, especially when parties are inherently distrustful. This distrust can stem from competition, confidentiality concerns, or past betrayals.

In traditional business settings, trust is established through contracts, agreements, and legal frameworks. Yet, these mechanisms often fall short in the digital age, where data breaches and unauthorized information sharing can erode trust. The challenge is finding a way to collaborate without exposing private data to potential risks.

## The Role of Multiparty Computation (MPC)

Multiparty Computation (MPC) is a solution that allows multiple parties to work together without revealing their private data. This technology uses cryptographic techniques to ensure that data can be computed and analyzed without sharing the underlying information. By enabling computations without exposing sensitive data, MPC reduces the risk of unauthorized access or misuse.

MPC’s unique approach to privacy and security makes it an ideal solution for scenarios where trust is difficult to establish. It provides a way to collaborate on sensitive projects without compromising confidentiality.

## Practical Applications of MPC

The potential applications of MPC are vast and diverse. Let’s explore a few real-world examples where MPC can facilitate collaboration among mutually distrustful parties:

### Financial Companies

Consider two financial companies that are competitors but need to work together on certain projects. They have sensitive information they want to keep private, yet they need to share data for business purposes. MPC allows these companies to collaborate on financial analyses without revealing their confidential data. This can lead to more comprehensive insights while maintaining privacy.

### Regulatory Compliance

Many companies must meet regulatory and compliance goals that require data sharing. However, exposing private information to the public or competitors can be risky. MPC enables companies to validate compliance with regulations without revealing sensitive data. This approach can help organizations meet regulatory requirements while protecting their proprietary information.

### Cybersecurity Collaboration

In the realm of cybersecurity, MPC can be a game-changer. Organizations often face similar threats but are reluctant to share information due to security risks. With MPC, they can collaborate on combating malware and ransomware without exposing themselves to additional vulnerabilities. This collaborative approach can strengthen the overall security posture of participating organizations.

### Data-Driven Partnerships

MPC also facilitates data-driven partnerships without compromising privacy. Companies can collaborate on projects that require data analysis without sharing raw data. This allows for innovative business models and partnerships that would be impossible without the privacy and security offered by MPC.

## Partisia Blockchain: Pioneering Collaboration Through MPC

Partisia Blockchain is at the forefront of implementing MPC in the blockchain space. The platform combines MPC with blockchain technology to create a trustless environment where collaboration can flourish. By integrating MPC with blockchain’s decentralized architecture, Partisia Blockchain enables a new era of collaboration among mutually distrustful parties.

The Partisia Blockchain team has developed a programming language that allows developers to use MPC in a generic way. This opens the door to creating applications that harness the power of MPC for various use cases. The platform has been providing private MPC solutions since 2008, and its focus on privacy and security makes it an ideal choice for businesses seeking collaboration without compromising confidentiality.

Conclusion

Collaboration between mutually distrustful parties is a complex challenge, but Multiparty Computation (MPC) offers a path forward. By enabling secure and private collaboration, MPC can revolutionize how businesses, organizations, and governments work together. Partisia Blockchain’s innovative approach to MPC and blockchain technology is paving the way for a new era of trust and cooperation in the digital age. As more companies embrace this technology, the possibilities for collaboration without compromise will continue to grow.

At the World Economic Forum in Davos, Partisia Blockchain made a significant announcement that has the potential to revolutionize the way we think about digital asset security. The company unveiled its latest product, MOCCA, which stands for MPC On-Chain Custody Advanced solution. This decentralized and fully programmable multichain custody solution is designed to change the landscape of securing digital assets, providing a new level of security and ease in custodial management.

## What is MOCCA?

MOCCA is a groundbreaking custody solution that leverages secure multiparty computation (MPC) to deliver a decentralized and programmable approach to managing digital assets. Unlike traditional custody solutions that are often centralized and rigid, MOCCA offers enhanced programmability through smart contracts, allowing users to customize their custody experience.

The key differentiators of MOCCA include:

**Decentralization**: MOCCA eliminates the need for a centralized authority to manage custody, reducing the risk of single points of failure.
– **Programmability**: The custody smart contracts are fully programmable, allowing users to define their own policies, modify threshold signature schemes, and integrate NFTs with specific permissions.
– **Multichain Functionality**: MOCCA is blockchain-agnostic, supporting multiple blockchains, offering flexibility and choice to users.
– **Advanced Security and Compliance**: MOCCA incorporates 35 years of MPC research to ensure robust security and compliance with regulations like GDPR.

## Redefining Custody with Programmable Smart Contracts

One of the most significant features of MOCCA is its programmability. Users can define their own policies for custody, allowing them to add or remove signers, modify threshold signature schemes, and even create specific rules for different types of transactions. This level of customization offers unparalleled flexibility in how digital assets are secured.

MOCCA’s smart contracts are designed to be easy to deploy, with customizable templates and tools. This means that users can quickly set up their own custody solution without the need for complex technical expertise. By using MPC, MOCCA ensures that key shards are generated and stored by users or MPC clusters, providing a high level of security.

## Advanced Security and Compliance

Partisia Blockchain’s MOCCA solution is designed with security and compliance in mind. It offers advanced features such as off-chain signing, key decentralization, and automatic key rotation to safeguard against potential threats. The custody smart contracts are deployed on public blockchains, ensuring transparency, while key shards are stored securely by users or MPC clusters.

The flexibility and security of MOCCA make it an ideal solution for a wide range of users, including institutions, decentralized autonomous organizations (DAOs), wallet providers, and exchanges. With MOCCA, users can secure digital assets across multiple blockchains without compromising security or compliance.

## MOCCA Roadmap

Partisia Blockchain has ambitious plans for MOCCA, aiming to provide a custody solution that meets the diverse needs of the blockchain community. The solution is designed to be scalable and adaptable, with a focus on delivering unparalleled security and programmability.

The roadmap for MOCCA includes further enhancements to its multichain functionality, improved compliance features, and additional support for customizable policies. Partisia Blockchain is committed to continuously improving the solution to ensure it remains at the forefront of digital asset security.

Conclusion

Partisia Blockchain’s MOCCA solution represents a significant leap forward in the field of digital asset custody. By combining
