CODAR Tech Africa : Leading Centre For Coding and Software Development in Africa

About this course

Blockchain is a decentralized, distributed ledger technology that records transactions across multiple computers in a secure, transparent, and tamper-proof manner. It operates using cryptographic principles and consensus mechanisms to ensure trust and integrity without the need for a central authority. Commonly used in cryptocurrencies like Bitcoin, blockchain also has applications in supply chain management, finance, healthcare, and more.
