description Etherum se ejecuta en redes de cadena de Bloques (Blockchain) a través de código personalizado, facilitando su implementación en diferentes áreas. Aprovecha la inmutabilidad y trazabilidad para aprobar transacciones independientes de una entidad central. Sin embargo, se han identificado problemas transaccionales como cuellos de botella. Este artículo presenta un modelo de desempeño de transacciones con Aprendizaje Automático, que analiza métricas en tiempo real, detectando anomalías. El modelo se probó con una secuencia de transacciones ideales y adversas determinando su efectividad. Palabras-clave: Cadena de Bloques, Ethereum, Rendimiento, Aprendizaje Automático, Métricas, Cuello de Botella.

Palabras-clave: Cadena de Bloques, Ethereum, Rendimiento, Aprendizaje Automático, Métricas, Cuello de Botella.Etherum runs on Blockchain networks through custom code, facilitating its implementation in different areas. It leverages immutability and traceability to approve transactions independent of a central entity. However, transactional problems have been identified as bottlenecks. This paper presents a transaction performance model with Machine Learning, which analyzes metrics in real time, detecting anomalies. The model was tested with a sequence of ideal and adverse transactions to determine its effectiveness.
