Chainlink (LINK)
Chainlink is a token oracle network, it is one odd cryptocurrency as it doesn't run its blockchain instead it runs its smart contracts simultaneously on other blockchains. This smart contract issue has over time reduced Chanklink's audience, but even at that, its worth has been unprecedented as it finds its way into the top cryptocurrency of 2021. As an oracle network token, it provides data and price collected from real-world sources.
