A. Definition of blockchain technology

At its core, blockchain is a decentralized and distributed digital ledger that is used to record transactions and store data in a secure and transparent way. The technology is based on a network of computers that work together to validate and authenticate transactions. Each transaction is verified by multiple nodes in the network, and once it is confirmed, it is added to a block that contains a unique digital signature. This block is then added to the existing chain of blocks, forming an unalterable chain of information. This makes it virtually impossible to tamper with the data stored on the blockchain, making it a secure and transparent way to store information. The technology is widely used in the financial industry, but its applications extend far beyond finance, including supply chain management, healthcare, and even voting systems.
