Abstract: A method for supporting verification of information pertaining to a target includes detecting an indication that a request transaction has been received by a smart contract deployed on a blockchain, the request transaction indicating a request to verify information pertaining to the target. The method also includes retrieving the request based on the request transaction. Further, the method includes: generating a reply transaction indicating at least (i) a reply to the request, and (ii) an address, on the blockchain, of an originator of the request; and providing the reply transaction to the smart contract.

Abstract: A method for securely verifying information pertaining to a target includes generating a request transaction indicating at least (i) a request to verify information pertaining to the target, and (ii) an address, on a blockchain, of a third party to which the request is directed. The method also includes providing the request transaction to a smart contract deployed on the blockchain. Further, the method includes detecting an indication that reply transaction corresponding to the request transaction has been received via the smart contract, and retrieving the reply transaction via the smart contract to determine whether the third party has verified the information.
