In the ever-evolving landscape of digital finance and cryptocurrencies, security remains a paramount concern. To achieve secure and private transactions, advanced cryptographic techniques are indispensable. One such innovation that has been gaining prominence is the Multi-Party Computation (MPC) wallet. In this article, we will delve into the pivotal role MPC wallets play in upgrading your overall security parameters, and how Bitget MPC Wallet leverages on cutting-edge technology such as large prime number generation to keep your private keys safe.


Understanding MPC

Within an MPC network, participants with private data (d1, d2, …, dN) work together to calculate a public result (F) while guarding their individual data. Consider the classic "Millionaire's Problem," where John, Rob, and Sam want to find the highest salary without disclosing their earnings (d1, d2, d3). They aim to compute:

F(d1,d2,d3) = max(d1,d2,d3)

The objective of MPC is to craft a protocol that allows John, Rob, and Sam to communicate solely amongst themselves, enabling them to determine F(d1,d2,d3) without disclosing individual earnings or needing an external third party. In essence, their knowledge gained from participating in the MPC should remain no more revealing than if they had consulted their trustworthy mutual friend.


What is an MPC Wallet?

Traditional wallets, whether hot, cold, or hardware, all carry with them their own unique set of weaknesses and vulnerabilities. This is where an MPC Wallet steps in.

Unlike traditional wallets that rely on a single private key, MPC wallets leverage the power of multiple parties, or shares, to perform cryptographic operations securely. In doing so, these wallets achieve a level of security that surpasses traditional single-key wallets, ensuring that even if one key share is compromised, the overall security of the system remains intact.

To create a valid digital signature required to sign a transaction securely within an MPC wallet, all participating parties are required to apply their key shares to the transaction.


Advantages of MPC Wallet

MPC wallets offer several advantages that make them an appealing choice for users. These benefits include the elimination of the need to trust third parties, enhanced data privacy, improved accuracy in computations, the elimination of single points of failure, increased resistance to hacking attempts, and reduced reliance on cold storage solutions.

1. Protection Against Single Points of Failure

By distributing key shards among multiple parties, MPC wallets effectively eliminate single points of failure (SPOF). Unlike traditional wallets that rely on a single location or device to store private keys, MPC wallets distribute the key fragments across different systems and locations. This decentralized approach mitigates the risks associated with the compromise or loss of a single storage location, thus increasing the overall security and resilience of the wallet system.

For private key generation, Bitget MPC Wallet utilizes distributed key generation technology to create "implicitly mapped complete private key" shares through multi-party collaborative computing. Each key share contains a fragment that will never be transmitted, guaranteeing that private key shares remain secure and that complete private keys are never exposed or leaked, avoiding the possibility of single-point failure.

2. Trustless Authentication System

One notable advantage of MPC wallets is the removal of the need to rely on trusted third parties. With MPC technology, data can be distributed among multiple parties without the involvement of intermediaries, ensuring that users have direct control over their assets and reducing the risk of reliance on potentially untrustworthy entities.

3. Data Privacy

Data privacy is another key benefit of MPC wallets. Through the use of encryption, both at rest and in transit, sensitive information remains protected. This ensures that no private data is compromised or exposed during storage or transmission, offering users a higher level of confidentiality and control over their personal information.

4. Computational Accuracy

The accuracy of computations is significantly enhanced with the application of MPC technology. By employing cryptographic techniques, MPC enables precise and reliable results for various computations, providing users with accurate outputs while maintaining the confidentiality of their private data.


Various Types of MPC Wallets

While MPC Wallets are typically assumed to be reserved for enterprise-level users, this is not always the case. In fact, there exists a variety of different MPC Wallet models catered for specific use cases, as we will outline below.

Consumer-Centric Products (toC Products)

Consumer-centric MPC products, often referred to as "toC" (for consumers), have revolutionized the landscape of cryptographic technology by democratizing access to secure key management. These solutions prioritize ordinary users who may not have extensive technical knowledge in the field. They are engineered to be user-friendly, emphasizing simplicity, accessibility, and a stellar user experience.

In practical terms, consumer-centric MPC products are built around the concept of usability. They strive to make cryptographic solutions and secure key management accessible to the masses. One of their primary objectives is to lower the barriers of entry for everyday individuals, allowing them to leverage advanced cryptographic techniques without grappling with intricate technical details.

These toC products often come in the form of user-friendly applications and interfaces, making it as easy as possible for consumers to secure and manage their digital assets. Users can generate, protect, and recover cryptographic keys without extensive technical know-how. By doing so, these solutions enable individuals to enjoy the benefits of strong security and data protection without the complexities that traditionally accompany cryptographic technologies.

Enterprise-Grade MPC Solutions (toB Products)

Enterprise-grade MPC solutions, commonly denoted as "toB" (for businesses), represent a critical segment of the cryptographic technology landscape. These products are designed to meet the specific needs and requirements of businesses, institutions, and organizations. The core focus of toB solutions is security, as these entities often deal with sensitive, high-value data and assets.

Security is paramount in the world of enterprise-grade MPC. These solutions are engineered to provide robust security measures that are essential for the protection of valuable assets, intellectual property, and sensitive information. This is particularly important for businesses operating in industries where regulatory compliance and data security standards are rigorous.

Enterprise-grade MPC products offer a range of features tailored to the unique demands of the corporate world. They often include advanced access control, audit trails, multi-signature support, and other security mechanisms necessary for enterprise-level operations. Additionally, these solutions may provide scalability options to accommodate the growth and evolving needs of businesses.

Developer-Centric Technology Middleware

Developer-centric technology middleware constitutes an integral part of the MPC ecosystem, serving the needs of software developers and technical experts. These solutions come in the form of essential components such as APIs (Application Programming Interfaces) and SDKs (Software Development Kits).

The primary objective of developer-centric technology middleware is to streamline the process of building applications that incorporate MPC capabilities. It provides developers with the tools, resources, and building blocks necessary to create applications that leverage secure key management and cryptographic techniques without needing to reinvent the wheel.

One of the key focal points of these solutions is scalability.

The Power of Bitget MPC Wallet

Bitget MPC Wallet provides several unique functionalities that places it ahead of the MPC game, offering unparalleled security parameters for users.

"2/3" Signature Mechanism

Bitget MPC Wallet features a unique "2/3" signature mechanism, setting it apart from most MPC wallets tailored for other toC MPC products. This mechanism provides an extensive enterprise-level MPC technology solution for everyday users.

The "2/3" signature mechanism introduces a minimum quorum requirement for signature authorization, necessitating the involvement of 2 out of 3 total key shares for the completion of a digital signature. Among these key shares, one resides on the user's current device, another is securely stored on the platform's server, and the final key share is housed on a backup cloud server like iCloud or Google Drive. Importantly, this third key share is not used for signature verification but is instead reserved for resharing purposes.

This approach achieves a notably higher degree of decentralization and security compared to alternative methods. It stands in contrast to hybrid hosting, where control over the private key is shared between users and platforms, preventing either party from unilaterally accessing funds. It also differs from third-party hosting, where platforms exercise absolute control over the private key, consequently having full access to user funds.

Large Prime Number Generation

At the heart of Bitget MPC Wallet lies the utilization of large prime numbers in encryption. Prime numbers, those divisible only by 1 and themselves, have long been a cornerstone of cryptography. The significance of prime numbers lies in their mathematical properties that make them extraordinarily difficult to factor into their constituent primes, which is a characteristic that Bitget Wallet employs to generate key shares.

To generate a prime number, most computational software simply involves the derivation of "Common Large Primes", which generates prime number "Q" - a random prime number.

This process is typically quick, as the algorithm only has to satisfy the condition that "Q" has to be a prime number. However, this oftentimes also leads to the outcome where prime number "Q" is not very long and may therefore be vulnerable to attacks, as will be outlined later below.

Bitget MPC Wallet, on the other hand, charts a more secure path by opting for "Secure Large Primes" in key generation. This meticulous selection process adheres to specific rules, aligning with the rigorous standards of the 2048 Merkle Tree Accumulator (MTA) guidelines.

Here's how it works in a nutshell:

Similar to the generation of "Common Large Primes," this method initiates the creation of a prime number "Q." However, it introduces an additional condition: that the prime number's length must satisfy the stringent criterion of "2Q - 1," and the outcome must also remain prime. If even a single condition is not fulfilled, the result is regenerated again until all conditions are satisfied.

TL;DR: Bitget MPC Wallet carefully generates large prime numbers that ensure robustness and resistance to attacks, as opposed to conventional prime encryption methods that may yield shorter prime numbers and are therefore more vulnerable.

Large prime numbers are crucial for enhancing the security of MPC wallets. They resist factorization due to their complexity, making it incredibly challenging for attackers to break the encryption. This robustness deters malicious actors, ensuring the safety of digital transactions and sensitive data. Furthermore, large prime numbers provide protection against quantum computing threats, which could compromise traditional encryption methods using smaller prime numbers.


Security vs. Speed: Striking a Balance

It's only natural for users to wonder why their Bitget MPC Wallet creation process might take longer compared to other, seemingly faster alternatives. The answer lies in the delicate balance between security and speed.

While some wallets might offer a quicker setup process, they often compromise on security. They may use smaller prime numbers or take shortcuts in cryptographic operations, making them more susceptible to hacking attempts. In the world of digital finance, where assets can be irreversibly lost, the need for robust security measures cannot be overstated.

In this context, Bitget MPC Wallet stands as the bedrock of security by prioritizing the protection of user assets and data, even if it means requesting users to exercise patience during the wallet creation process. This added wait time is not a detriment, but rather, a reassurance of uncompromised security.
