FEAR OF THE UNKOWN

  • Unclear benefits
  • Non-matching mental models
  • Terrible UX

WHAT ARE MENTAL MODELS?

  • Relatively precise mental image of our regular activities
  • Defines how we interact with known processes or with something similar to them
  • Formed by our earlier experiences
  • Typical financial activities also based on mental models
  • Swipe bankcard
  • Send money
  • Take out money from ATM

MENTAL MODEL FOR CRYPTOCURRENCIES?

  • No proper model
  • Reality is too complicated
  • No real rutine (e.g torrenting 10 years ago)
  • Far removed from our financial habits
  • Teenagers will have earlier mental model for cryptocurrencies than for standard banking

SIMILARITIES TO REAL MONEY

  • Can be transferred
  • Can be exchanged
  • Represents value
  • Bankers are the miners

HOW CRYPTOCURRENCIES DIFFER?

  • Starts with a lot of 0s
  • Addresses cannot be spoken or memorised
  • Mistakes are easy to make
  • Sending fees are changing
  • Inheritance is complicated

ONBOARDING

  • Education is needed due to radical innovation
  • Differences should be emphasised
  • Progressing in steps
  • Active guidance: hints, tooltips
  • All secenarios should be covered

COMMUNICATION

  • Be clear and current
  • Explain the next steps
  • Help users understand the current stage
  • Humanise the conversation: Telex AI chatbot / voicebot

TRUST

  • Trustable design (Desirability test)
  • Predictable
  • Consistent
  • Data exposure

GIVING FEEDBACK AND ERROR HANDLING

  • Explain the result of the last steps
  • Pay special attention to irreversible actions
  • Show how cryptocurrencies differ from fiat moneys

CRYPTOKITTIES THE UX SUCCESS

  • Reliable, modern frontend
  • Transparent, easy-to-understand communication
  • Established UX patterns
  • Built-in gamification
  • Plays with the notion of scarcity and uniqueness

ISSUES TO CONSIDER WHEN DESIGNING BLOCKCHAIN INTERFACES

  • There is no easily applicable mental model
  • The users try to get a grasp of reality
  • Bad experience prevents adaption
  • Reliable research for better understanding
  • Education and active guidance
