Can blockchain help me switch into the IT industry?

Blockchain is a distributed record technology in which transactions can be stored in linked, tamper-evident records. MCA students interested in the area should understand distributed systems, consensus and smart-contract concepts. This makes blockchain more valuable when it is supported by hands-on practice and a clear explanation of what you built. This point is specifically relevant to the blockchain aspect of MCA study. For this specific question about blockchain, the practical takeaway is to relate the concept to your own MCA learning goal.
