The invention discloses a
power grid data sharing method and
system based on a block chain and a data resource
directory. The method comprises the steps of obtaining a
data sharing request sent by a data demander through a block chain, and obtaining identity information and
data identification information in the
data sharing request; querying a data middle
station module according to the identityinformation and the
data identification information, and performing authority
verification based on a query result; when the authority
verification is passed, obtaining to-be-shared data correspondingto the
data identification information from the
data center station module; and obtaining the
smart contract from the block chain, triggering a triggering condition specified by the
smart contract according to the identity information and the data identification information, performing data sharing according to a
service process corresponding to the triggering condition, and publishing the data sharing process and the data sharing information to the block chain, so that whole-course recording and
traceability of
power grid data in the aspects of access convergence, business processes, use circulation and the like are ensured, and the problems of
power grid data in the aspects of right confirmation
authentication,
security privacy and credible sharing are solved.
