Towards Usable Blockchain Interfaces – Understanding Seed Phrase Storage in Practice

An increasingly popular method to generate private/ public key pairs for cryptocurrency wallets is Hierarchical Deterministic Key Generation based on a series of random words. These words (mnemonics) can be stored and subsequently used to (re-)generate the original private key file, in case it is lost.

The goal of this thesis is to analyze how users actually store these phrases in practice, to look at the benefits and drawback of different strategies and ultimately develop a new concept for improved handling of mnemonics.

This thesis is currently being worked on. If you have similiar ideas in this area, reach out to me.
