Table 3 The specific tasks of each role within the logical framework.
From: Research on multi-person collaborative design of BIM drawing based on blockchain
Role | Specific tasks |
|---|---|
CA | Generating public/private key pairs for BIM_O and BIM_D |
BC | Integrating \(DDI\) to generate \(DFDI\), storing data (e.g.,\(DDI_{record}\), \(DFDI_{record}\), \(DAI_{record}\), etc.) and performing data encryption, signature and verification |
IPFS | Storing complete BIM drawing |
BIM_O | Updating and uploading BIM drawing according to \(DFDI\) |
BIM_D | Acquiring and designing BIM drawing, then uploading them after calculating \(DDI\) |
