A growing dialogue on user boards reveals new insights about the 12th and 24th words in seed phrases, indicating they aren't just standard checksums. This has raised concerns over wallet recovery and how it impacts users who depend on these phrases.
Context and Significance
Seed phrases aid in wallet security. Traditionally, many thought the final word was simply a checksum for verification. However, recent discussions confirm that there are various acceptable last words for the same initial set, complicating the recovery process.
Key Themes Emerging from Discussions
Variability of Last Words
Participants are highlighting that the final word isn't unique. One contributor stated, "Each one will produce a different wallet, so, not good for recovery." Another noted that there are 128 possible 12th words and 8 possible 24th words for any 11/23 combination of BIP39 words.
Complications in Wallet Recovery
The complexity arising from multiple valid last words leaves many questioning their wallet recovery strategies. A notable comment pointed out, "So it’s not just one correct word but a few possibilities. That’s actually good to know for recovery." This realization emphasizes the need for users to grasp the implications for security.
Entropy and Checksum Misunderstandings
The conversation has pointed out that many are not aware of the entropy the final words hold. As one user succinctly stated, "which is why multiple valid last words can sometimes exist for the same partial phrase. Not sometimes. ALWAYS." This highlights the mathematical intricacies and how they might impact user understanding.
"It’s fascinating how the final word isn’t magic, just math with multiple acceptable endings" - User Insight
