A storage mechanism of data access record on consortium chain based on master-slave blocks.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Although data on the blockchain cannot be tampered with, malicious access by insiders can also lead to data leakage. Access records of block are an important basis for tracing the source of data breaches; however, access records themselves may be tampered with. Therefore, it is important to study how to protect the block access records. So far, the protection of block access records has not received much attention. To make block access records a protected data resource as well, this paper proposes a storage mechanism of data access record on consortium chain based on master-slave blocks. In this mechanism, the master block is used to store data resources, and the slave block of the master block is used to store access records of the master block. This method ensures that the slave block has the security characteristics of the single chain block, making the access record traceable and immutable. The storage mechanism's viability is confirmed by real-world experimentation. The proposed mechanism outperforms the single chain in terms of data query performance, according to the testing results on public data sets.
