Abstract

Implementaciones de la presente descripción incluyen recibir, por un nodo de cadena de bloque en la red de cadena de bloque, una petición para leer un bloque particular de la cadena de bloque, en donde la petición se recibe de un nodo ligero de la red de cadena de bloque e incluye una identidad del nodo ligero, y en donde el bloque particular incluye un árbol de Merkle original asociado con el bloque particular; identificar, por el nodo de cadena de bloque, permisos asociados con la identidad del nodo ligero; generar, por el nodo de cadena de bloque, un árbol de Merkle aislado con base en el árbol de Merkle original incluido en el bloque, el árbol de Merkle aislado que incluye únicamente transacciones del árbol de Merkle original que se determina que son accesibles por el nodo ligero con base en los permisos identificados, en donde el árbol de Merkle aislado es consistente con el árbol de Merkle original; y enviar, por el nodo de cadena de bloque, una respuesta al nodo ligero que incluye el árbol de Merkle aislado.
