What are good use cases for Blockchain?

Blockchain technology serves many productive use cases in different industries other than cryptocurrencies. The use cases of blockchain in banking and finance reflect international payments, trade finance, capital markets, peer-to-peer transactions, and insurance. Decentralized Finance, or DeFi, is the biggest example to prove the application of blockchain for transforming the conventional centralized financial systems. Another promising use case of blockchain technology is evident in the domain of digital identity systems. The blockchain-based digital identity systems could offer interoperable and unified infrastructures for secure identity management. On top of it, users would have better control and ownership privilege over their data. Blockchain technology can also serve vital improvements with use cases in energy and sustainability. Enterprise-grade blockchain solutions for oil and gas companies can break down the traditional siloed infrastructures and pave the road for better transparency, optimization, and efficiency.
