Despite all the media hype about the rise and fall of cryptocurrencies, blockchain technology is still in its infancy, meaning it’s an ideal time for designers to step in and help build new systems. There’s no shortage of challenges to address. Here are three juicy ones to get started thinking more deeply about blockchain, the unique experiences the technology enables, and how it could be integrated into our everyday lives.
The beauty of cryptocurrency is that it’s possible for you, and only you, to have access to your crypto wallet and assets. That means you get to have true ownership; your “account” information isn’t stored by a bank or central authority that can use or take away your assets at will (think of governments seizing funds, for example). Instead, the data is stored in a universal ledger across a distributed network that can independently verify who owns what—so it’s much more transparent than most of today’s banking systems.
Of course, that power also comes with great responsibility. There is no password or account recovery if you lose or reveal your private key (sometimes expressed in the form of a 24-word phrase), which is used to “unlock” your wallet. Giving that away is like dropping cash on the street—you likely won’t get it back.
Challenge: Design secure and user-friendly ways to store private keys.
A few questions to get you started:
Some inspiration:
Every time you transact in Ethereum, a platform for blockchain applications, you have to set your gas price—the amount you are willing to pay for the computation needed for your transaction be confirmed. An easy analog is paying more for expedited shipping to get your package mailed there sooner.
Those prices and speeds are not determined by any one party (like FedEx, for instance), but by how busy the network is, how many other transactions are waiting to be confirmed, and what gas price those other transactions are using. But information about current network state is rarely communicated to the user—adding frustration and confusion when setting your best guess at gas price. Too low? Your transaction might not go through for a long time (or ever). Set it too high, and you risk paying more than you need to.
Remember the early days of eBay, before they included shipping rates in transactions? You had to wait for a day or so until the seller got back to you with the actual shipping costs. Sometimes it was what you’d expected, sometimes it bit you in the butt.
Challenge: Design better ways to help users make a decision about transaction costs, or find ways to abstract it away all together.

Some inspiration:
Crypto wallet addresses currently look something like this: 0x04De111196aCE9764b6eCAcC4f849b6b59193443—a string of 40 characters, which serve the function of being cryptographically unique (i.e. impossible to guess). While there are experiments like ENS, a human-readable domain system for blockchain addresses, they aren’t widely adopted yet. Sending a crypto transaction today means checking and double-checking 40 characters that look like gobble-de-gook. And you need to get it right the first time, since there are no refunds or rollbacks for crypto transactions.
That’s like having to type in the bank account number of every merchant or person you’d like to transact with, every single time. If it’s off by one digit—cue instant regret.
The challenge: Design ways to display blockchain addresses in a more readable or recognizable format.
