Abstract
Background:
As innovative information technology, blockchain has combined the
advantages of decentralization, immutability, data provenance, and contract operation automatically,
which can be used to solve the issues of single point failure, high trading cost, low effectiveness,
and data potential risk in power trading. However, in the traditional power blockchain,
the design of functional components in blockchain, such as the data structure of the block, does
not take the actual features of power into account, thus leading to a performance bottleneck in
practical application. Motivated by business characteristics of power trading, a user-centric data
model UCDM in consortium blockchain is proposed to achieve efficient data storage and quick
data retrieval.
Methods:
The proposed UCDM is designed by considering the requirements of transaction retrieval
and analysis, thus supporting the requirements of concurrent data requests and mass data
storage. The ID of each user will independently form its own chain over the blockchain.
Results:
Compared with the traditional data model, the extensive experimental results demonstrate
that the proposed UCDM has shorter processing delay, higher throughput, and shorter response
latency, thus having practical value.
Conclusion:
UCDM is an effective solution to the transaction retrieval and analysis in power
blockchain. Furthermore, the participant of the blockchain network has a unique identity over the
world, which ensures high security during trading.
