Description: Distributed Ledger Technology (DLT) is a system that enables the secure and transparent recording of transactions across multiple locations without the need for a central intermediary. This technology is based on the creation of a shared and decentralized ledger, where each participant in the network has access to the same information, ensuring the integrity and immutability of the data. The main features of DLT include transparency, cryptographic security, and resistance to tampering. In the context of modern industries, DLT becomes a fundamental pillar for the digitization of processes, allowing for product traceability and optimization of supply chains. In the realm of Federated Learning, DLT facilitates collaboration among different entities without compromising data privacy, enabling learning models to be trained jointly without the need to share sensitive data. This technology not only enhances operational efficiency but also fosters trust among the involved parties, which is essential in an increasingly interconnected and competitive business environment.
History: Distributed Ledger Technology began to gain prominence with the introduction of Bitcoin in 2009, which utilized a form of DLT known as blockchain. Since then, the technology has evolved and diversified, with the development of different types of DLT that do not necessarily require cryptocurrencies. Throughout the 2010s, significant advancements were made in the research and development of DLT, with applications extending beyond cryptocurrencies, including smart contracts and electronic voting systems.
Uses: Distributed Ledger Technology is used in various applications, such as supply chain management, where it enables the traceability of products from their origin to the end consumer. It is also applied in the financial sector to facilitate secure and fast transactions, as well as in digital identity management. In the healthcare sector, DLT is used to secure the exchange of medical data between different entities, ensuring the privacy and integrity of the information.
Examples: A practical example of Distributed Ledger Technology is the Hyperledger Fabric platform, which allows companies to create private networks for securely managing transactions. Another case is the use of DLT in the food industry, where companies like Walmart have implemented traceability systems to track the origin of products and ensure their safety. In the realm of Federated Learning, projects like OpenMined use DLT to enable collaborative training of artificial intelligence models without compromising user data privacy.
