10. Trustless Construction Project Information Exchanging Using Hyperledger Blockchain

The distributed ledger is an immutable record for data stored inside it. This technology can be helpful for construction project events and communication recording. This article investigates the Hyperledger project, a modular enterprise Blockchain with pluggable products to create a construction communication and data exchange ledger. Hyperledger is an open-source modular Blockchain architecture designed to help enterprises run distributed ledgers to benefit from the technological advancement provided by Blockchain technology. These ledgers are immutable, distributed, and trustless. These features allow for transparent communication between stakeholders, which could positively impact construction project workflow and the participation of projects actors. The article uses Hyperledger products Fabric and Composer to showcase a hypothetical Blockchain to exchange project metadata and communication between construction project participants. The article presents an example of using Blockchain for the construction project process by designing a Blockchain to handle the Request for Information (RFI) process.
