Metamask: What is the Web3 approach to storing secret tokens (for example, when need to store the local salt for commit/reveal pattern)?

Web 3 of secret token storage: a guide

The web 3 approach revolutionizes the way we store and manage secret tokens, in particular with regard to sensitive information such as salt values. In this article, we will explore what web3 has to offer in terms of storage of secret tokens, including local storage alternatives.

What are web3 tokens?

The web3 tokens represent a new era for digital assets, allowing users to transfer value and make transactions without the need for intermediaries such as centralized exchanges (CEX). These tokens often use cryptographic techniques, such as encryption of public keys and hash, to ensure secure and decentralized transactions.

The problem with local storage:

When it comes to locally store secret tokens on a user’s device, there are several problems:

• Security risks : Storage of sensitive information such as salt values ​​directly on the customer side (that is to say in local storage) can cause data violations or unauthorized access .

• Interoperability : Different platforms and web walks and portfolios may require separate storage mechanisms, which makes it difficult for developers to create transparent user experiences.

Web 3: approach

To respond to these concerns, web 3 approaches offer innovative solutions to locally store secret tokens:

• Zero knowledge evidence (ZKP) : Z KP allows users to store sensitive information such as salt values ​​without revealing it publicly. This allows secure storage and data transfer between nodes on the blockchain.

• Homomorphic encryption (IL) *: It provides a secure means of calculating operations on encrypted data, ensuring that sensitive information remains confidential even when stored locally.

• Zero hash signatures: Zero hash signatures allow users to store secret tokens without storing raw data. Instead, they can use an identifier based on the hash to manage access and allow transactions.

Alternative storage mechanisms:

When local storage is not achievable or desirable (for example, for mobile applications), web3 approaches offer alternative storage mechanisms:

• Wallet based on the blockchain : Web3 wallets, like Metamask, store secret tokens in the local browser cache (that is to say in the storage of the browser). This offers transparent user experience and ensures security via ZKP or him.

• Decentralized storage services : Decentralized storage services, such as Infura or Alchemy, offer secure and scalable storage solutions for web3 applications.

Conclusion:

Web3 approaches have revolutionized the way we store secret tokens locally. By taking advantage of zero knowledge of knowledge, homomorphic encryption and zero hash signatures, developers can create transparent user experiences that guarantee the security and confidentiality of sensitive data. When local storage is not achievable, alternative storage mechanisms provide a secure and scalable solution for web3 applications.

Recommendations:

For developers creating web3 applications, consider implementing one or more of the following elements:

• Zero knowledge evidence (ZKP) as ZXP or ZKSNF

• Homomorphic encryption solutions (IL) like the hive or the big book

• Zero-hash signatures (ZHS) libraries like ZHS SDK

By adopting these approaches and alternative storage mechanisms, developers can create robust and secure web3 applications that store secret tokens locally with confidence.
