Every time a new trend emerges, the first ones to profit are usually those selling water—whether it's the shared economy evolving from traditional leasing models or blockchain, which believers claim will revolutionize the future.
If it hadn't been for Bitcoin reaching $20,000 last year, maybe the blockchain era would have taken a step back. Now, with various "halos" surrounding blockchain and big players entering the scene, it's hard to say whether this is genuine progress or just another hype cycle.
Despite the massive development in blockchain technology, its real impact on surrounding industries still seems no different from other speculative trends. It's more of a buzzword than a revolutionary force at this point.
Recently, Lagou published a list of high-paying blockchain jobs. Companies like Tencent, Alibaba, Xiaomi, JD.com, Thunder, and Meitu are offering salaries ranging from 15k to 70k per month for blockchain-related positions. However, the highest salary listed was Kodak’s, reaching 85k to 100k monthly. The data also shows that in Hangzhou alone, the number of blockchain job postings increased by 16,000 compared to January, with tech roles rising by 12,132, community operations by 1,870, content editing by 106, and business roles by 80.
Back when Bitcoin prices were soaring, the public was fascinated by whether this digital phenomenon could offer a new path to wealth and social mobility. Figures like Li Xiaolai and Xue Manzi became central figures in the crypto world, and blockchain was mainly used to explain what digital currency was.
Things changed quickly. As ICOs began revealing their ugly side, the so-called "$5 billion air" scams made many people lose trust in Li Xiaolai and others. Combined with regulatory crackdowns, speculation led many long-term investors to quit, while newcomers were discouraged.
Afterward, Xu Xiaoping’s group chat and the government’s support for blockchain (at least not opposing it) allowed the concept to persist. When policy restrictions eased, we saw “full-screen†blockchain, much like how AI became a hot topic after the national AI strategy was announced.
The most direct evidence is that the Baidu index for blockchain surpassed Bitcoin yesterday, and search volume for blockchain increased by 1000% in just one month.
For some companies, there's actually little difference between AI and blockchain—they're both just marketing tools to attract venture capital. Of course, there are still firms genuinely trying to build something with blockchain, otherwise they wouldn’t be offering million-dollar annual salaries in the early stages of the industry.
The current high fever around blockchain has inevitably given rise to a new industry: training. When iOS development took off, many institutions in first- and second-tier cities quickly opened courses, producing dozens of graduates every few months. But soon the market became oversaturated, and the window period lasted only about two years.
However, the blockchain training boom seems a bit off track. Instead of focusing on trainees, the real demand is for blockchain instructors. According to reports, some training centers can produce 80 lecturers in just three days.
Yet, for the extremely scarce positions, training institutions seem to be moving slowly. Even though a well-known institution like Tuanzhi Podcast added a blockchain course, after contacting customer service, it turned out only one class had been offered. The price was only slightly higher than iOS training from a year ago.
In fact, blockchain as a technical idea doesn’t involve any specific technologies. Many training programs look similar to traditional Java or .NET courses, making it easy for institutions to rebrand existing content as "blockchain development."
This way, these institutions don’t seem to realize that the concept of blockchain is more of a marketing tool than a real skill set. By packaging old Java, .NET, and C++ courses into "blockchain," they’re attracting confused college students who are just catching up with the trend. Some even graduate in two or three months, right before the next wave of job seekers hits the market.
Of course, training institutions are supposed to educate and teach people. This kind of approach should be avoided, but it’s clear that many are chasing the trend without understanding the real value behind it.
