What should I know about blockchain projects before joining an MCA?

A strong MCA project should solve a clear problem and demonstrate real technical work. A student can strengthen it with proper documentation, testing, source control and a working demonstration. If your target role involves blockchain projects, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the blockchain projects aspect of MCA study. For this specific question about blockchain projects, the practical takeaway is to relate the concept to your own MCA learning goal.
