Securing digital assets is of utmost importance in the realm of cryptocurrency. Recent events, exemplified by the Ledger scandal, have highlighted the necessity for strengthened security measures within the crypto community. This article delves into the significance of security in the crypto space and explores advanced features like No KYC wallets, multi-signature wallets, and MPC technology. Furthermore, it examines how Unido's solution empowers users to confidently and effortlessly take charge of their crypto assets. 


The Need for Heightened Security Measures 


As the popularity of cryptocurrencies continues to surge, the imperative for enhanced security measures becomes more apparent than ever. In a recent development, Ledger has launched an optional subscription service in the latest Nano X Firmware, the Ledger Recover. It aims to help and protect users by enabling them to back up their Security Seed Phrase and easily recover their wallet in case their original Ledger device is lost, damaged, or stolen. 

This appears to be a good update; however, many users have expressed their concerns about this development as the keys are divided into three fragments by the Secure Element, which then proceeds to encrypt them. Ledger retains one fragment while the others are distributed to third-party entities. 

In the crypto community, Ledger gained popularity as users of the service believed that no party (even Ledger) was incapable of accessing the seed phrase, whether in plain text or encrypted form, and that no firmware upgrade could alter this outcome. The release of Ledger Recover contradicts the practice of ‘self-custody' that Ledger has been advocating since conception – as other parties would have access to their keys, increasing the risk of security breaches.  


No KYC Wallets: Embracing Privacy and Anonymity 


No KYC (Know Your Customer) wallets have become increasingly popular in the crypto community. These wallets offer users the freedom to store and transact cryptocurrencies without undergoing the Know Your Customer (KYC) procedures. This means users can retain control over their personal information and, enjoy a higher level of privacy in their crypto transactions and reduce the chances of identity theft.   


Multi-signature wallets and its limitations 


Multi-signature wallets have been hailed as a step forward in enhancing crypto asset security by requiring multiple signatures for transactions. However, as the cryptocurrency landscape evolves, it becomes evident that multi-signature solutions have their limitations. 

One of the main challenges with multi-signature wallets is their lack of protocol agnosticism. Not all cryptocurrency protocols support multi-sig, and even among those that do, implementations differ significantly, making it harder for wallet providers to securely support multiple blockchains. 

Additionally, multi-sig wallets can be operationally inflexible. As digital asset businesses grow, they may require adjustments to access and transfer processes. Changing the number of required signatories, adding or revoking key shares, or modifying signature thresholds can be cumbersome with multi-signature wallets, as they come with pre-set configurations that are not easily adaptable to evolving needs.  


Multi-Party Computation: Addressing today’s challenges 


Multi-Party Computation (MPC) is the next generation of private key security. MPC is inherently designed to address the challenges faced by multi-signature wallets in today's dynamic digital asset landscape. 

At its core, MPC eliminates the concept of singular access to a private key by distributing individual key components among multiple endpoints, such as servers or mobile devices. These key components are physically distributed and never shared data with each other, ensuring there's no single point of compromise for the private key. During the transaction signing process, a quorum of endpoints engages in distributed signature computation, individually validating the transaction and signing it without exposing the private key. 

MPC's distributed nature offers significant operational advantages over multi-signature wallets. Team members can require multiple authorizers for a transaction and sign transactions from different locations, making it highly flexible for enterprises and institutions as they grow and change. Unlike multi-sig, which often requires creating new wallets and addresses for each additional signer, the concept of Multi-Party Computation (MPC) allows for ongoing modification and maintenance of the signature scheme. This feature enables easy adaptation to changing requirements without disrupting existing operations. As a result, MPC offers a flexible and dynamic approach to managing cryptographic keys and signatures in various transactions.  

It is worth noting that multi-signature wallets require much higher transaction fees primarily due to the need to process multiple signatures from different participants, leading to higher fees on the network.  

Moreover, MPC is designed to be protocol agnostic, making it a future-proof solution that can seamlessly support new blockchain networks as they emerge in the ever-evolving cryptocurrency space.
