This article introduces a hybrid blockchain architecture to enhance Electronic Medical Record (EMR) management and interoperability. It integrates a permissioned public blockchain on Polkadot—managing roles and permissions—with a private blockchain on Hyperledger Fabric responsible for EMR storage. Text data are stored in CouchDB and medical images in IPFS as Non-Fungible Tokens (NFTs), following a patient-centric model. Stress tests yielded average latencies of 2050 ms for EMR creation and 2000 ms for sharing, with 65 % CPU and 170 MB memory usage, indicating system stability and efficiency. The proposed architecture provides a scalable, secure, and interoperable solution suitable for healthcare environments that demand data confidentiality and controlled access.

Digital transformation and Industry 4.0 represent a revolution in business models, production processes, and information management, driven by the development and application of advanced technologies. This study aimed to explore the state of digital transformation in Peruvian companies from the perspective of their leaders. The research had an exploratory and descriptive scope, with a mixed-methods approach, and focused on identifying the progress of digital transformation processes within organizations. A sample of 20 large companies was considered: 18 located in the Lima region and 2 in the highlands. Through a survey, their management models, human talent, methodologies, and technologies used were analyzed. The results revealed that a company’s digital maturity is closely linked to its human capital, digital methodologies, and the technologies it employs. It was also found that the ...
