In the context of rapidly advancing technology, asserting digital identity becomes extremely important. Vitalik Buterin, one of the co-founders of Ethereum, recently shared insights on the risks that digital identity still faces, even when applying measures like ZK-wrapping. Although ZK-wrapping addresses many critical issues, proving identity through zero-knowledge still carries many risks related to privacy, coercion, and errors. This article will explore in more detail the risks of digital identity and how new measures can provide effective solutions.
Introduction to ZK-wrapping in digital identity
ZK-wrapping is a technology that helps protect personal information by concealing sensitive details when proving identity. It removes the need to disclose detailed information while still allowing for verification. This technology has received significant attention from the cryptocurrency community, especially in protecting transactions and personal data.
Although ZK-wrapping offers many benefits, it is not entirely immune to risks. The biggest risk is that the identity protection provided by ZK-wrapping is not always strong enough to prevent attacks. Threats may come from outside or from the users themselves.
The risk of maintaining 'one person, one identity'
The ability to maintain the principle of 'one person, one identity' has become a significant challenge. Risks associated with this include personal information leaks, coercion, and inaccuracies. When identity is determined in a single way, users can become victims of attacks or conflicts.
The reality is that maintaining a consistent identity for each person is not easy, as a single identity cannot reflect all aspects of an individual. This raises a significant question about how we can manage and use digital identity in the future.
Using 'asset proof' against Sybil attacks
To combat Sybil attacks, some solutions have proposed the use of 'asset proof'. However, this cannot fully meet the needs of real-world use cases. Relying solely on assets to determine identity is unreasonable in many situations, making it an imperfect solution.
Therefore, developing a more flexible and effective identification system is extremely necessary. This may include combining elements such as financial identity and social identity to create a more diverse entity for each user.
Ideal solution: Multi-identity
The ideal solution for digital identity issues may lie between two extremes: a single identity and a completely separate identity. A multi-identity system allows users to express different aspects of themselves in a safe and private manner. This strategy not only helps minimize risks but also enhances security.
Multi-identity can include various types of zero-knowledge proofs, thereby relieving pressure from a single model. Each person can use different identities for different purposes without worrying about exposing sensitive personal information.
Identity verification through social databases
To optimize the operation of a multi-identity system, the use of social databases can help provide a stronger solution. Relying on social relationships, we can automatically verify identities without requiring too much personal information.
This not only helps protect privacy but can also prevent fraud and attacks. Social databases help establish trust for identities while enhancing the user experience in interacting with online services.
Conclusion: Towards the future of digital identity
The future of digital identity depends on the ability to develop more comprehensive and robust solutions. As risks such as information leaks and coercion increase, seeking effective protection methods like ZK-wrapping or multi-identity systems becomes extremely important.
Ultimately, raising awareness of the importance of digital identity will help users better protect themselves. Along with technological advancements, optimizing and verifying identity will open up many new opportunities in the cryptocurrency world and in real life.
