A visual representation of a seedphrase containing two identical words highlighted to show potential security risks

A surge of conversations in the crypto space has people questioning the design choices surrounding duplicated words in seed phrases, particularly the surprising appearance of the term "academic" twice. As users seek clarity, feelings of confusion and reassurance swirl around wallet security and the implications of the Single-share Backup setting.

What is Slip39 and Why Does It Matter?

The confusion stems from Slip39, a method designed for multi-signature wallets. As one contributor remarked, "It’s normal, it’s part of multisign backups." This highlights that repeated words denote single-share backups, quelling fears of potential security risks.

User Perspectives on the Seed Phrase Design

While many embrace the technical aspects, some users criticize the apparent design flaws. Remarks include:

  • Design Concerns: "Maybe from a user experience point of view, this was a bad design choice."

  • Statistical Insight: One commenter explained, "It can happen. For a BIP39 seed, repeated words have a chance of about 1/170 for 12 words and 1/85 for 24 words."

  • Positive Reinforcement: The sentiment shifts toward reassurance with many noting, "Absolutely normal for Slip39."

Misunderstandings Persist

Not all users are on the same page. A notable distinction arises in discussions comparing Slip39 to BIP39, with one user stating, "Not normal at all for BIP39." This indicates a crucial need for clear communication within the community about the differences between the two standards.
