Abstract

Las implementaciones de la presente descripción incluyen determinar un primer número de un índice que corresponde a uno de un primero o más pares de clave-valor (KVS) de árbol de Merkle Patricia (MPT) usado por una base de datos de contratos inteligentes; determinar, con base en el primer número del índice, una primera clave de un primer KVP de un segundo o más KVS de un mapa para atravesar el MPT; determinar un primer valor que corresponde a la primera clave del primer KVP; determinar una segunda clave de un segundo KVP del segundo o más KVS; y recuperar el segundo valor que corresponde a la segunda clave del segundo KVP.
