Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

open access: yesCivil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.
Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized

Efficient asynchronous accumulators for distributed PKI [PDF]

open access: yes, 2016
Cryptographic accumulators are a tool for compact set representation and secure set membership proofs. When an element is added to a set by means of an accumulator, a membership witness is generated. This witness can later be used to prove the membership

IoT Technology as an Effective Strategy Enhances Food Authentication for Current Fresh Fruit Supply Chain

open access: yesFuture Postharvest and Food, EarlyView.
ABSTRACT With trade globalization, food fraud such as tampering, substituting, and falsifying, challenges human health and the management of food supply chain. As a food type that only processed at primary level, the authenticity of fruit supply information has become a guarantee for its edible safety.
