Mecanismos de Transparência e Auditoria de Blockchains Permissionadas
Resumo
Blockchains permissionadas, como as privadas e consorciadas, são comuns em contextos que demandam controle de acesso. Porém, ao restringir os participantes da rede, diminuem a transparência do sistema. Diante disso, este trabalho propõe uma ferramenta de auditoria de blockchains permissionadas baseada no compartilhamento descentralizado do estado da blockchain via Interplanetary File System (IPFS). A partir de uma implementação utilizando Hyperledger Fabric, foram desenvolvidos mecanismos que permitem que entidades externas à rede blockchain possam identificar e se recuperar de alterações indevidas, ataques de visão fragmentada, uso de contratos inteligentes distintos dos declarados pela rede e execução de transações inválidas.Referências
