Chainlink smart contracts have many useful applications. These include government, authorisation and identity, utilities, supply chain, insurance, enterprise systems, gaming and random number generators, external payments processing, and DeFi (decentralised finance). Crypto-secured systems and networks can also benefit from Chainlink technology. On-chain and off-chain smart contracts enjoy crypto-secured functionality, with tamper-proof data, and censorship-resistance. From a practical perspective, smart contract adoption is highest among certain industries like the insurance industry, derivatives, and trade finance. The reason smart contracts are preferred in these industries is that they facilitate trustless contracts between clients and companies.
