CAD AND BLOCKCHAIN TECHNOLOGY INTEGRATION MODEL FOR THE PURPOSE OF DATA PROTECTION
Keywords:
blockchain, Cad, BIM, Ethereum, cryptographic keys, data integrityAbstract
Distributed and interactive environments, such as computer aided design (CAD), including building information modeling (BIM) and geographic information systems (GIS) in construction and architecture as well as product data management and/or product lifecycle management (PDM/PLM) in mechanical engineering. In any case, it is necessary to preserve the integrity of data in these computer applications, which builds user confidence in CAD and BIM data. Blockchain technology is increasingly being used to address data integrity in interactive CAD environments. Blockchain is built from blocks that are linearly connected, in chronological order, which creates a permanent and immutable digital ledger of all transactions on the network. The use of smart contracts, self-executing contracts with terms of agreement between buyers and sellers written directly into computer code, has further expanded the potential uses of blockchain. The first smart contracts were implemented on the Ethereum blockchain in 2015, and have since become a key feature of blockchain technology. Blockchain technology, like everything else we use, has its advantages and disadvantages. The essential advantages of blockchain are: data integrity, reliability, traceability, decentralization, persistence, anonymity. Disadvantages such as data transparency and the slowness of data archiving in blockchain should not be a reason to abandon the implementation of blockchain in wider use.
