Blockchain is a distributed ledger technology that provides a secure and transparent way to store and verify transactions and data. With immutable and decentralized records, it eliminates the need for intermediaries, reduces costs and increases trust in transactional processes.
In the real world, blockchain has several advantages: in the financial sector, it facilitates fast and global payments without bank fees; in supply chain tracking, it provides complete visibility and authenticity of products, especially in industries such as food and fashion. In governments, it increases the transparency and security of electoral processes and documentation, such as property records. In the healthcare sector, it allows the secure and accessible storage of medical records. In addition, its use in smart contracts automates agreements and reduces bureaucracy.
These applications make blockchain a promising technology for a more transparent, secure and efficient world, offering solutions that have the potential to transform several sectors.
