| Summary: | To combat the problem of illegal access to a service, several location proof strategies
have been proposed in the literature. In blockchain-based decentralized applications, transactions
can be issued by IoT nodes or other automated smart devices. Key pair encryption and private
key signing have been defined mainly for human identification in blockchain applications, where
users are personally and responsibly concerned about the confidentiality of their private key. These
methods are not suitable for computing nodes whose private key is implemented in the software
they run. Ensuring that transactions are issued by a legitimate sender with the proper credentials is a
bigger concern in applications with financial stakes. This is the case with blockchain energy trading
platforms, where prosumers are credited with tokens in exchange for their contributions of energy.
The tokens are issued by smart meter nodes installed at fixed locations to monitor the energy inputs
and outputs of a given prosumer and claim energy tokens on its behalf from a defined smart contract
in exchange for the energy it feeds into the grid. To this end, we have developed a decentralized
Proof-of-Location (PoL) system tailored to blockchain applications for energy trading. It ensures that
automated transactions are issued by the right nodes by using smart contract-based random selection
and a game-theoretic scenario suitable for blockchain energy trading. |
