Short answer: Yes, you can.
Long answer: There is a tremendous amount of data generated by blockchain transactions. This on-chain data is pseudonymous. Therefore it requires Data Science to decipher and break down this information at scale.
Indexing Protocols like The Graph are working on enabling querying and making this data searchable. Others are on a mission to make this data more accessible and visible, such as Covalent.

Over time, aggregating this data and interpreting it will be vital for companies, DAOs, governments, or other organizations to analyze markets and trends. I also predict that when more intersections of Machine Learning and Web3 occur, we will be seeing more and more data science and research positions.
