Blockchain technology emerged as a revolutionary force in the financial sector, initially powering Bitcoin during the 2008 global financial crisis. Its distributed ledger technology (DLT) offers a secure, transparent method to transfer and track data without relying on centralized authorities like banks. By requiring unanimous approval from network nodes, blockchain ensures tamper-proof transactions while addressing industry pain points such as security breaches and operational inefficiencies.
