Abstract
Blockchain has attracted wide attention in both industry and academia due to its decentralized and anti-tamper characteristics. To query the blockchain data, all the transactions in the blockchain must be iterated one by one, which is quite inefficient. Existing solutions improve the query efficiency by exporting transactions to external databases, and yet they incur the incompleteness and incorrectness of query results. To avoid above weaknesses, we propose an efficient query method based on the internal blockchain database and apply it to the construction engineering management to solve the problems of information management. In our design, we construct a dual-index based on the B+ tree and the key-value pair through smart contracts, and it supports multiple query operations, such as range query and file-type query. We implement the designed method by simulating the blockchain testbed and the experimental results demonstrate the efficiency of our design.
