Is Chainlink only on Ethereum?

Is Chainlink really confined to Ethereum alone? I've heard so much buzz around this decentralized oracle network, but isn't it possible for it to operate on other blockchain platforms? After all, the world of crypto is vast and evolving rapidly. Could Chainlink potentially expand its reach beyond Ethereum in the future? Or are there technical limitations that restrict its functionality to this specific blockchain? I'm genuinely curious to know if Chainlink's integration is truly exclusive to Ethereum or if there's room for more diverse applications.
