media, for controlling access to a property based on smart contract execution. One of the methods includes receiving credential data 
for a first entity requesting access to a property; in response to receiving the credential data, requesting execution of a smart contract 
associated with the property by a blockchain network, wherein the smart contract includes instructions to check a current status of a 
= relationship between the first entity and a second entity associated with the property based on the credential data; receiving an execution 
result of the smart contract from the blockchain network; determining that the first entity is authorized to access the property based 
at least in part on the execution result; and in response to determining that the first entity authorized to access the property, enabling 
the first entity to access to the property.
