Blockchain technology is a decentralized system that records digital transactions across a network of computers, ensuring transparency and security. Each transaction is stored in a block, which is linked to the previous one, forming a secure and unchangeable chain. This technology eliminates the need for intermediaries, making processes faster and more efficient. While it is widely known for supporting cryptocurrencies, blockchain technology is also used in finance, healthcare, supply chains, and more. Its ability to prevent data tampering makes it a powerful tool for building digital trust.
