This eliminates the need for a central authority to verify information and allows for a faster, more secure method of confirming the accuracy of data and the legitimacy of transactions. The technology is open source, permissionless, and highly resistant to hacks or system failures.

Already, distributed validator technology is making inroads into finance perspectives. However, the potential applications of this technology are vast and diverse. The time is now to gain an understanding of how distributed validator technology works and how you can implement it to gain a competitive advantage. This overview article will provide the information you need to determine if and how your organization can benefit from this cutting-edge innovation.

The main issues of staking Ethereum (ETH)

As Ethereum transitions to a proof-of-stake consensus mechanism, investors will be able to stake their ETH to earn rewards. However, staking also presents some issues that are important to understand:

· Centralization risk. Various retail users with small amount of ETH encounter hardships in setting up and maintaining validator in Proof-of-Stake (PoS) system, in which requires the minimum of 32 ETH for validator’s operation. Therefore, they shift to custodial staking services (centralized exchange platforms) to stake their ETH for more convenience with less costly entrance fee. However, numerous risks occur regarding centralization. The fact of entitling private keys to central authority can pose the threat of slashing penalties, errors, hacks and possible censorship, damaging the global monetary network**.**

· Keys theft. Based on Ethereum PoS rules, a validator is limited to signing messages and remaining online through a single device, which houses the private keys comprising signing keys and withdrawal keys. Consequently, if these keys are not adequately secured, malicious actors can potentially gain unauthorized access to the private key by compromising the validator's computer, resulting in fund losses and introducing a concerning single-point-of-failure risk.

· Node failure. This issue arises when validators experience disruptions such as software bugs, network connection failures, or hardware crashes, impeding their ability to sign messages effectively. Consequently, if validators go offline during the process of signing messages, they are subject to slashing penalties, which are imposed as a consequence of their inactivity. These slashing penalties result in a proportional reduction of their staked balances, thereby highlighting the potential financial repercussions faced by validators due to such operational interruptions.

To tackle the challenges mentioned above, the Ethereum roadmap is looking towards Distributed Validator Technology (DVT) as a significant solution in the upcoming phase known as "The Merge." DVT is expected to play a crucial role in addressing issues related to validator performance, security, and scalability, making it an integral part of the Ethereum ecosystem's future evolution.

What Is Distributed Validator Technology (DVT)?

By definition, DVT refers to a decentralized open-source protocol that enables validator's duties to be distributed among multiple nodes, as opposed to a single machine, leveraging threshold cryptography.

To put it simply, Distributed Validator Technology (DVT) employs a mechanism where the private keys are distributed across multiple computers, enabling multiple parties to hold a portion of the private key. By doing this, attackers would face significant challenges in gaining access to complete private keys because it is not fully stored in a single machine. This approach effectively mitigates the risk of a single point of failure, reinforcing fund's security.

Furthermore, DVT incorporates decentralized layers of fault-tolerance, enabling validators to maintain continuous performance even in the presence of failures or malfunctions. This architectural design enhances the overall resiliency of the system and effectively reduces the occurrence of slashing penalties.

The mechanism of DVT

Distributed validator technology (DVT) relies on a network of validator nodes instead of a single centralized validator. This decentralized approach offers several benefits over traditional validation methods.

Distributed Key Generation

To enable the functionality of DVT, an essential step is the splitting private validator key into multiple parts, corresponding to the number of participants in the consensus group. This approach facilitates the distribution of partial private key portions among various parties, ensuring that no individual within the group possesses knowledge of the complete private key. Consequently, this preventive measure safeguards against the possibility of a malicious group member individually signing messages and subsequently gaining control over the validator node.

Shamir's Secret Sharing

Shamir's Secret Sharing is an algorithm that enables the reconstruction of a private key without necessitating access to every individual key share. Consequently, even in the event of a node being offline or engaging in malicious behavior, the remaining nodes retain the capability to reconstruct the private key and perform message signing. This resilient approach effectively mitigates the risk of slashing penalties.

Multi-party Computation

By combining Distributed Key Generation and Shamir’s Secret Sharing, this stage enables Distributed Validator Technology to function effectively. Multi-party Computation allows the cluster of operators to sign messages and perform computations without rebuilding the complete private key on a single device. this step eliminates risk of centralizing the private key, thereby maintaining decentralization and get rid of centralization risks.

Istanbul Byzantine Fault-tolerance

The Istanbul Byzantine Fault Tolerance (IBFT) algorithm is utilized to designate one Beacon node as the leader. The leader proposes the block to other Beacon nodes, and if over 66% of them approve it, the block is added to the blockchain. If the designated leader goes offline or becomes compromised, IBFT will reassign the role to another DVT Beacon node within 12 seconds. This dynamic reassignment mechanism ensures the continuous operation and resilience of the DVT network.

Potential pros and cons of DVT implementation

Increased Security and Transparency

DVT has the potential to significantly strengthen network security and increase transparency. By decentralizing validation authority, DVT makes it much harder for malicious actors to manipulate network activity or gain control of the network. Without a central point of failure, the network becomes more resilient against attacks.

Minimized slashing and downtime risks

With the application of Distributed Key Generation and Shamir's Secret Sharing, the algorithm designates additional fault-tolerance layer for making it easier to operate despite malfunctions or errors occurring. As a result, validators will be prevented from slashing penalties.

Higher Costs

There are also likely to be higher infrastructure and operating costs associated with DVT networks. Maintaining many validator nodes and ensuring they stay in sync requires substantial investments in computing resources and networking equipment. These costs would likely be passed on to network users and participants in some form. Some argue the added security and transparency benefits of DVT outweigh the higher costs.

Governance Challenges

Finally, DVT networks present unique governance challenges related to upgrading protocols and making other network changes. Achieving consensus and coordinating software upgrades across many independent nodes can be difficult. However, strong open governance models that balance decentralization and practicality are being developed. Governance is likely to be an ongoing process of trial-and-error for DVT networks.

Overall, while DVT shows a lot of promise for improving network security, transparency, and resilience, there are also notable drawbacks and challenges to consider regarding transaction speeds, costs, access, and governance. With further development, many of these potentially negative impacts could be mitigated.

The Future of DVT

A Promising Future

DVT has the potential to transform industries and positively impact society in meaningful ways. As it continues to advance, several promising use cases are emerging that could drive mainstream adoption over the next decade.

Fraud Prevention and Compliance

DVT shows promise for improving fraud detection and regulatory compliance. Its distributed nature makes tampering with or hacking the system extremely difficult. DVT could help ensure that critical data, records, and transactions are valid and compliant with laws and regulations.

Supply Chain Management

DVT may enhance supply chain management by providing a trusted record of the origin, transportation, and transaction details for goods and materials. This could reduce fraud, minimize disputes, and streamline auditing processes across global supply chains.

Healthcare

In healthcare, DVT could improve security, interoperability, and data sharing between providers and patients. A distributed and shared ledger of health records may give patients more control over their data while reducing opportunities for record tampering and medical identity theft.

Voting

DVT has the potential to increase trust and security in voting systems. An open, distributed ledger for voting could provide a transparent, auditable record of votes to prevent fraud and manipulation. However, challenges around privacy, access, and implementation would need to be addressed.
