Abstract

As formas de realização da presente invenção incluem receber, por um nó de protocolo de confiança na rede de protocolo de confiança, uma solicitação para ler um bloco particular do protocolo de confiança, em que a solicitação é recebida de um nó de peso leve da rede de protocolo de confiança e inclui uma identidade do nó de peso leve, e em que o bloco particular inclui uma árvore Merkle original associada ao bloco particular; identificar, pelo nó de protocolo de confiança, permissões associadas à identidade do nó de peso leve; gerar, pelo nó de protocolo de confiança, uma árvore Merkle isolada baseada na árvore Merkle original incluída no bloco, a árvore Merkle isolada incluindo somente transações da árvore Merkle original que são determinadas como sendo acessíveis pelo nó de peso leve com base nas permissões identificadas, em que a árvore Merkle isolada é consistente com a árvore Merkle original; e enviar pelo nó de protocolo de confiança, uma resposta ao nó de peso leve incluindo a árvore Merkle isolada.
