What exactly is the threshold to become a Web3 data analyst? To put it simply, you need to understand on-chain data thoroughly. This is not an empty claim—mastering the ability to decode on-chain transactions can cover 90% of your work scenarios, which means being able to directly interpret on-chain behavior without UI and ABI interfaces. The rest is straightforward: use Python or SQL to turn these insights into actionable results. The tech stack isn't complicated, but the depth of understanding must be sufficient. True competitiveness comes from whether you can thoroughly grasp the raw blockchain data.
