dc.description.abstractBlockchain technology has transformed information management through decentralization, security and immutability. However, a gap persists in its application for the issuance and verification of professional qualifications in education. This study presents a prototype developed in Python and Docker, designed to guarantee the authenticity and traceability of academic credentials through a hybrid blockchain network with six Docker nodes. The prototype includes processes such as initial data registration, node configuration, credential generation with QR codes and associative signature based on Byzantine consensus. During the signing stage, previously stored records are validated and authenticated, ensuring integrity before final credentials are generated. The peer-to-peer network ensures synchronization, decentralized storage and immutability of records. On average, initial title registration on the blockchain took 2.97 s, with block replication taking 0.02 s. Record signing had a latency of 0.96 s, with replication in 0.79 s, and Byzantine consensus took 0.12 s, all with moderate resource consumption. The generated titles, verifiable via QR codes, reinforce trust and reduce academic fraud. This model stands out for its practical and scalable approach, with potential for adaptation to other sectors. Future work should address the scalability and robustness of the system for more complex applications.

Sin embargo, persiste una brecha en su aplicaciĆ³n para la emisiĆ³n y verificaciĆ³n de cualificaciones profesionales en educaciĆ³n. Este estudio presenta un prototipo desarrollado en Python y Docker, diseƱado para garantizar la autenticidad y trazabilidad de las credenciales acadĆ©micas mediante una red blockchain hĆ­brida con seis nodos Docker. El prototipo incluye procesos como el registro inicial de datos, la configuraciĆ³n de nodos, la generaciĆ³n de credenciales con cĆ³digos QR y la firma asociativa basada en el consenso bizantino. Durante la etapa de firma, se validan y autentican los registros previamente almacenados, lo que garantiza su integridad antes de generar las credenciales finales. La red peer-to-peer garantiza la sincronizaciĆ³n, el almacenamiento descentralizado y la inmutabilidad de los registros. En promedio, el registro inicial de tĆ­tulos en la blockchain tardĆ³ 2,97 s, con la replicaciĆ³n de bloques en 0,02 s. La firma de registros tuvo una latencia de 0,96 s, con una replicaciĆ³n de 0,79 s, y el consenso bizantino en 0,12 s, todos con un consumo moderado de recursos. Los tĆ­tulos generados, verificables mediante cĆ³digos QR, refuerzan la confianza y reducen el fraude acadĆ©mico. Este modelo destaca por su enfoque prĆ”ctico y escalable, con potencial de adaptaciĆ³n a otros sectores. El trabajo futuro deberĆ” abordar la escalabilidad y robustez del sistema para aplicaciones mĆ”s complejas.
