币界网报道：Just a few weeks ago, Alex Blania, founder of World, revealed his latest strategic trump card to a room full of crypto leaders. While it is eye-catching to take advantage of the policy to seize the US market, the real stroke of genius is their lightning breakthrough into the mainstream consumer scene. This is a sign that cryptocurrencies are tearing off the label of "geek club" and truly entering the Shura field of daily business. World's move is ruthless enough: it is actually difficult to trick Americans into using iris scanning to exchange for a "real person certification badge", even if they promise privacy protection (and the timing may be too early). But they have already done something big: they have been secretly working for the past three years to lay three insurances for this crazy plan. Blania brought out three real pain points to prove this: dating, games, and credit fields. Now bots are rampant and it is difficult to distinguish between humans and machines. So he put World's "real person proof" system on the table and made it clear: why it is worth it for you to use your iris to scan the sphere and exchange for a ticket to "I am a real person". We all rushed into the early crypto boom. When I designed the Bitcoin experiment at MIT, I really thought that the payment and financial systems could be completely overturned in two or three years. Ten years later, we are just getting started. If you want to really push crypto products outside the circle, you have to align with the experience that traditional users and merchants have long been accustomed to. This means that a bridge must be built between the old system and the new technology. And this bridge often requires some compromises that are unorthodox in the eyes of "crypto fundamentalists". Whether crypto can succeed depends on implementation. Like all new technologies, crypto is not destined to win. Don't believe the myths of those self-indulgent fans. To be more specific, "decentralization", the soul pillar of crypto and its most critical contribution to subverting the market, has never been a sure thing. Blania and his team made a big bet: betting that users will care about decentralized control of data, and betting that companies will build a better user experience on this system. How difficult it will be to deal with decentralized identity once it impacts the existing pattern - centralized players have a natural advantage in UX and functionality at the beginning.
