I wasn't able to find specific information about a "央视财经区块链技术专家" from the search results. However, this term seems to refer to an expert in blockchain technology from CCTV's finance and economics division. CCTV is China Central Television, a major state television broadcaster in China. They likely feature experts to discuss blockchain technology within economic contexts on their programming. If you have more questions about blockchain technology or related topics, feel free to ask!
