That is the topic of my latest Bloomberg column, here is one bit:
Now the time has come for crypto to go on a diet. No more easy money. No more thoughts about ICOs leading to quick riches. The rhetoric is shifting toward a more cautious or even apologetic tone. The corresponding reality can perhaps be one of greater focus and relevance.
We’re at the point where crypto finally has to prove its social worth. But what might that mean? Imagine using crypto as a medium of micropayments to pay for media on the internet. Or perhaps you’ll use the blockchain to verify your identity, rather than telling some stranger on the phone the last four digits of your Social Security number. Or how about a system for self-executing, zero-cost contracts? (For example: I will give $10,000 to a charity if 10 other people do.) Maybe the burgeoning field of virtual reality will rely on crypto to support some of its transactions, starting with virtual sex, which the major banks might stay away from. Alternatively, I might use crypto assets to send money to Mexico, avoiding the steep charges from current money transfer systems. In the more utopian visions, crypto leads to the rise of entirely self-governing systems, powered by the blockchain.
By the way, if you are confused by the terms “proof of stake” and “sharding” (and others), that is probably a good thing. As the tech guru Stewart Brand is reported to have said, the proliferation of terminology in crypto is a sign that new ideas and possibly important new technologies are afoot.
