What industry is Chainlink in?

I'm curious to know, what industry does Chainlink operate in? It seems to be a hot topic in the crypto world, but I'm not entirely sure where it fits in the larger financial landscape. Is it more aligned with blockchain technology, or does it have a broader scope that encompasses traditional finance as well? Could you please provide a brief description of the industry Chainlink belongs to, and maybe even some insights into its significance and potential impact?
