detecting, by one or more processors of the computing system, 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;
retrieving, by the one or more processors, the request based on the request transaction;
generating, by the one or more processors, 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, by the one or more processors, the reply transaction to the smart contract.
