Debido a que los desarrolladores representan valores \"uint64\" como \"n\u00fameros\" nativos de javascript, se presenta un problema cuando esas variables con valores \"uint64\" grandes (mayores de 2^53) son incluidas en la cadena. En esos casos, Lodestar puede visualizar valid_\"AttesterSlashing\" o \"ProposerSlashing\" como inv\u00e1lidos, debido a errores de redondeo en valores \"num\u00e9ricos\" grandes. Esto causa una divisi\u00f3n del consenso, donde los nodos de Lodestar son bifurcados fuera de la red principal.
