Corda
Corda is an open-source distributed ledger platform designed for businesses to transact directly and privately using smart contracts. It enables secure, peer-to-peer transactions without a central authority, focusing on financial services, supply chain, and other industries requiring privacy and scalability. Unlike public blockchains, Corda restricts data sharing only to parties involved in a transaction.
Developers should learn Corda when building applications for industries like finance, insurance, or trade where privacy, regulatory compliance, and direct business-to-business transactions are critical. It's ideal for use cases such as trade finance, securities settlement, and supply chain tracking, as it offers deterministic finality and legal enforceability through smart contracts.
