Blockchain distributed risk data sharing system and method

The invention discloses a blockchain distributed risk data sharing system and method. The blockchain distributed risk data sharing system comprises a blockchain system, a business system and a servicesystem, wherein the business system receives a first query request submitted by a user, delivers the first query request to the connected service system, and feeds back a query result on the messagequeue to the user; and/or receives a second query request uploaded by the service system, processing according to the second query request, querying the local data in a ciphertext database collision mode to obtain a query result, and feeding back the query result to the connected service system; the service system obtains organization information corresponding to the first query request from the blockchain system according to the first query request, obtains a service system address corresponding to the first query request according to the organization information, delivers the first query request to the corresponding
