Blockchain
Blockchain is a decentralized, distributed ledger technology that records transactions across multiple computers in a secure, transparent, and immutable way. It enables peer-to-peer transactions without intermediaries, using cryptographic techniques to ensure data integrity and consensus mechanisms to validate entries. In banking, it facilitates applications like cross-border payments, smart contracts, and digital asset management.
Developers should learn blockchain for banking to build secure, transparent financial systems that reduce fraud, lower transaction costs, and enable real-time settlements. Key use cases include creating decentralized finance (DeFi) platforms, implementing anti-money laundering (AML) compliance through traceable ledgers, and developing tokenized assets for investment products. It's essential for roles in fintech, digital banking innovation, and regulatory technology.
