Solan’s mut' solution: Anchor's critical analysis

The Solana blockchain, built on the basis of the Anchor framework, has attracted significant attention and recognition from the cryptocurrency community. However, one of the aspects that requires further study is the processing of the "Survey" and "Subscriber" accounts. In this article, we'll look at the reasons why the host team decided not to allowmut’ for both accounts, despite its potential benefits in certain scenarios.

Problem with mut'

Mut'' allows a user account to modify the data of another account without the need for explicit transmission. This is especially useful when working with complex interactions between accounts or when a user needs to update information about someone else (for example, when creating a new user account). However, in the Solana contextmutis not enabled by default for several reasons:

  • Security: By limitingmut’, the organizing group seeks to maintain control over the flow of data and prevent potential security vulnerabilities.
  • Compatibility: Enabling mut' can lead to incompatibilities between different libraries or modules that rely on it, which can cause problems in the Solana ecosystem.

Decision not to issuemut’ permission

Taking into account the above-mentioned concerns, the organizers have decided not to grant mut' permission to thePoll'' andSigner'' accounts. The rationale for this decision is as follows:

  • No need for explicit translations: By turning offmut’, users can update information about someone else without requiring explicit translation of funds or data.
  • Maintaining security and compatibility: Enabling mut' can lead to potential security risks and incompatibilities that the organizing team strives to avoid.

Conclusion

The decision not to grantmut’ permission to Poll' andSigner’ accounts is a conscious choice made by the organizers. Although at first glance it may seem illogical, this solution was implemented taking into account security, compatibility and ease of maintenance. In conclusion, it should be noted that understanding the reasons for such a decision can help users make informed decisions about their Solana experience.

Best Practices

To get around these restrictions, follow these guidelines to keep your account data secure:

  • Use transfer instead of mut: If you need to update information about someone else, use the transfer function to transfer funds or data without having to get explicit mut permission.
  • Avoid using mut in complex interactions: Be careful when using mut in complex scenarios where security and compatibility are critical.

By understanding the core team’s decision-making process and following best practices, you can effectively use Solana while minimizing potential risks.
