What Is an MPC Crypto Wallet?

The top priority for digital assets and currency is security. In a space that's still maturing and not always heavily regulated, robust security is essential. MPC technology offers a strong safeguard, offering new layers of protection.

An MPC wallet functions similarly to other digital wallets, but it provides enhanced security. It divides the private keys and control across multiple devices. This division significantly reduces the chances of hacking, even if a malicious entity accesses one of the device's keys.

Benefits of MPC Technology in Wallets

Heightened Security

By distributing the private key across multiple devices or participants, MPC technology ensures that no single entity has access to the entire key. An attacker would need to compromise several, if not all, of these entities, making breaching the wallet exponentially more challenging and resource-intensive than targeting a single device.

Efficient Transactions

With MPC, transactions can be authorized through a consensus of key fragments without the need to reconstruct the entire key. This streamlines the process and facilitates quicker transaction times while facilitating utmost security.

User Flexibility

MPC technology offers the advantage of not tying down security to a single device or location. Users can access and approve transactions from multiple authorized devices, granting them more flexibility in their operations and increasing their security layers through device diversity.

Reduced Single Point of Failure

Traditional security systems often have a singular point of vulnerability or failure. In contrast, MPC wallets diversify this risk by distributing the key components. If one point is compromised, the overall system remains secure, offering a more resilient architecture against a variety of threats.

Scalability

MPC technology can easily scale to accommodate more participants or devices, making it a flexible solution for growing organizations or networks. As more entities are added, the security fabric becomes even denser, reinforcing its strength.

Enhanced Privacy

MPC technology operates on the principle of computing without revealing the actual inputs, promoting data privacy. Participants can authorize or validate transactions without ever disclosing their portion of the key, ensuring both security and confidentiality in operations.

How Does MPC Wallet Technology Work?

At its core, MPC technology allows a group to compute a function over their inputs without revealing them. This is enabled by a concept known as Zero-Knowledge Proof, which is pivotal for blockchain security.

Instead of a private key being vulnerable in one location, MPC wallets divide it into parts. These parts are then shared among multiple participants. These participants can carry out calculations independently, providing authorization without revealing their part of the code. Thus, rather than a key being in one location, it's perpetually segmented across the blockchain.

MPC vs. Multi-sig

Multi-sig Wallets

Multi-signature wallets call for multiple private keys to authorize a transaction. The wallet can be set up in such a way that, for instance, 2 out of 3, or 3 out of 5 (or any combination thereof) private keys are required to validate a transaction.

MPC Wallets

Instead of relying on multiple private keys, MPC wallets split a single private key into fragments and distributes them among participants. These participants can authorize transactions without ever combining the key parts or revealing their individual segments.

Advantage of MPC

While multi-sig increases security by distributing the authorization requirement across multiple keys, it still involves the risk of exposing entire keys. MPC, on the other hand, never exposes or combines the fragments of a key, making certain that even if one segment is under threat, the whole key remains secure.

MPC vs. Single-Key Wallets

Single-Key Wallets

These are traditional wallets where the private key is stored in a single location. If an attacker gets hold of this key, they gain full control over the assets.

MPC Wallets

As described, MPC scatters the private key in fragments among multiple participants. This means that even if one fragment is exposed, it's of no use without the others.

Advantage of MPC

If a participant's device is compromised, the entire key remains secure. Such redundancy is absent in single-key wallets.

MPC vs. Hierarchical Deterministic (HD) Wallets

HD Wallets

These wallets produce a hierarchy of keys from a single, master key seed. Different addresses can be produced from the same seed, providing enhanced privacy.

MPC Wallets

The security focus of MPC isn't on address generation but on distributing the key's fragments securely among participants.

Advantage of MPC

MPC focuses on verifying that even if one device is vulnerable, the overall security remains intact, making it more robust in the face of potential hacks.

MPC vs. Hardware Wallets

Hardware Wallets

These are physical devices that store private keys offline, making them immune to online hacking attempts. Transactions are signed within the device and then broadcast, ensuring the private key never leaves the hardware.

MPC Wallets

Being a conceptual approach, MPC technology can even be applied in conjunction with hardware wallets, scattering key fragments across multiple hardware devices.

Advantage of MPC

The combination of hardware wallets with MPC can offer an added layer of security, making it extremely challenging for attackers, as they'd have to compromise multiple hardware devices simultaneously.

MPC vs. Paper Wallets

Paper Wallets

As the name suggests, these are physical documents containing both the private and public keys. They're completely offline, making them immune to digital attacks.

MPC Wallets

Being a digital-first solution, MPC offers more flexibility and real-time transactions without the need for manual intervention, as opposed to paper wallets which are static.

Advantage of MPC

MPC provides a dynamic and more user-friendly approach, suitable for frequent transactions while maintaining robust security. In contrast, paper wallets are best for long-term, cold storage.

MPC: Solving the Crypto Wallet Problem

Traditional key storage had its flaws, especially when stored in single locations like a hardware security module. MPC revolutionizes this. With the concept of MPC custody, where keys are decentralized and held in parts by various participants who remain unaware of each other's identity, hackers face a formidable challenge.

Zert’s wallets utilize the rigorous security of MPC, providing a user-friendly experience without the necessity of cold storage solutions. With MPC underpinning Zert’s wallets, digital payments blend efficiency with security.
