Information sharing methods, apparatuses, and devices

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• receiving, from a blockchain network by a trusted execution environment (TEE) in a blockchain node, a trigger instruction based on a timed starting logic, wherein the timed starting logic identifies a starting time to execute a smart contract, wherein the timed starting logic is comprised in a chain code associated with the blockchain network, and wherein the chain code comprises information of a blockchain account and is executable by the blockchain node to determine the information of the blockchain account;
• combining, by the TEE, first anti-money laundering (AML) risk information and second AML risk information based on the trigger instruction to obtain a combination result, wherein the first AML risk information is sent by a first institution for a first user ID of a user, the second AML risk information is sent by a second institution for the user;
• and
• sending, by the TEE, the combination result to the first institution.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving, from a blockchain network by a trusted execution environment (TEE) in a blockchain node, a trigger instruction based on a timed starting logic, wherein the timed starting logic identifies a starting time to execute a smart contract, wherein the timed starting logic is comprised in a chain code associated with the blockchain network, and wherein the chain code comprises information of a blockchain account and is executable by the blockchain node to determine the information of the blockchain account;
• combining, by the TEE, first anti-money laundering (AML) risk information and second AML risk information based on the trigger instruction to obtain a combination result, wherein the first AML risk information is sent by a first institution for a first user ID of a user, the second AML risk information is sent by a second institution for the user;
• and
• sending, by the TEE, the combination result to the first institution.
