Abstract: A system and method for executing and recording transactions for a key in a blockchain. A method includes creating a smart contract on receiving a request to order a key on lease for a first period of time. The method further includes determining an availability of the key and determining an availability of digital tokens in an account of the user. The method also includes executing the smart contract for the first period of time by executing a first transaction using the digital tokens and recording the executed first transaction and the executed smart contract in a block of a block chain to provide the key on lease.

Abstract: Aspects of the invention are directed towards methods and systems for managing access of an application. One or more embodiments of the invention describe receiving an indication from a user to access an application. One or more embodiments of the invention further describe determining whether a user device is in an offline mode and if the user device is in the offline mode, prompting the user to input user credentials. Furthermore, the embodiments of the invention also describe receiving the user credentials from the user and validating the user credentials of the user with pre-stored user credentials. Accordingly, access of the application to the user is controlled based on said validation.

Abstract: Aspects of the invention are directed towards a system and a method for providing access of an accessing device to a user. One or more embodiments of the invention describe a method comprising steps detecting an access card by an accessing device associated with a premises and establishing a communication between the accessing device and a user device after detecting the access card. Further, the method comprises steps of generating user credentials for a user of the user device to access the accessing device and transmitting the user credentials to the user device to access the accessing device using the user credentials.

Abstract: A system and method for executing and recording transactions in a blockchain. A method includes creating a smart contract on receiving a request to order a key-box on lease for a first period of time. The method includes determining an availability of the key-box and determining an availability of digital tokens. Accordingly, the smart contract is executed for the first period of time by executing a first transaction and the executed first transaction and the executed smart contract are recorded in a block of a block chain. The includes receiving a request to extend the lease of the key-box for a second period of time, executing a second transaction, updating the smart contract and recording the updated smart contract and the executed second transaction in the block.
