3. Section: The Future of BlockchainThe Rise of DeFi (Decentralized Finance) and NFTsInnovative Uses and Potential ProblemsHow Blockchain Technology Can Change SocietyConclusion: A Summary About the Importance and Future of BlockchainEach of these topics can be written in more detail and each can be covered in a Blockchain, as the name suggests, is a system in which data is stored in a chained manner in packages called blocks. Each block is linked by a hash (a unique ID) that also contains the data of the previous block. This structure ensures immutability of data because if the information in a block changes, the hash of that block changes, which disrupts the integrity of the chain. As new data is added, the transaction occurs with the approval of many computers in the network (called miners or nodes). This process is a complex mathematical operation performed using cryptographic algorithms. In this way, data manipulation or fraud attempts are prevented. This operation has a decentralized structure, meaning that there is no need for a single authority to store and verify data. The transparency and security of blockchain are important features that enable it to be used in many sectors (finance, healthcare, supply chain, etc.).
