With the continuous maturity of blockchain technology and the popularity of its applications, we expect that a more diversified blockchain product will emerge in the market, and the blockchain is facing a shortage of talent. Blockchain talent is a typical composite talent who researches and develops the underlying technology of the blockchain, and understands the regional chain technology and related industry knowledge.
