Query: SPB: A Secure Private Blockchain-based Solution for Energy Trading   Blockchain is increasingly being used to provide a distributed, secure,
trusted, and private framework for energy trading in smart grids. However,
existing solutions suffer from lack of privacy, processing and packet
overheads, and reliance on Trusted Third Parties (TTP). To address these
challenges, we propose a Secure Private Blockchain-based (SPB) framework. SPB
enables the energy producers and consumers to directly negotiate the energy
price. To reduce the associated packet overhead, we propose a routing method
which routes packets based on the destination Public Key (PK). SPB eliminates
the need for TTP by introducing atomic meta-transactions. The two transactions
that form a meta-transaction are visible to the blockchain participants only
after both of them are generated. Thus, if one of the participants does not
commit to its tasks in a pre-defined time, then the energy trade expires and
the corresponding transaction is treated as invalid. The smart meter of the
consumer confirms receipt of energy by generating an Energy Receipt
Confirmation (ERC). To verify that the ERC is generated by a genuine smart
meter, SPB supports authentication of anonymous smart meters which in turn
enhances the privacy of the meter owner. Qualitative security analysis shows
the resilience of SPB against a range of attacks.
