Blockchain for Food Supply Chain Transparency
Research Guide
What is Blockchain for Food Supply Chain Transparency?
Blockchain for Food Supply Chain Transparency uses distributed ledger technology to create immutable records of food provenance, enabling tamper-proof tracking from farm to consumer.
Research integrates blockchain with RFID and IoT for real-time data logging in agri-food chains (Tian, 2016, 962 citations; Feng et al., 2020, 725 citations). Key studies model traceability systems addressing scalability and privacy (Kamble et al., 2019, 878 citations). Over 10 high-citation papers since 2016 examine smart contracts and interoperability challenges.
Why It Matters
Blockchain enables fraud detection in global food networks by verifying origins, as shown in China's RFID-blockchain system reducing safety incidents (Tian, 2016). It builds consumer trust through transparent labeling, countering mislabeling like 30% error rates in European seafood (Miller and Mariani, 2010). Gálvez et al. (2018) highlight applications in outbreak tracing, cutting recall costs by 40% in simulations, while Feng et al. (2020) demonstrate sustainability gains via verified eco-friendly sourcing.
Key Research Challenges
Scalability Limitations
Blockchain networks struggle with high transaction volumes in global food chains, causing delays (Kamble et al., 2019). Feng et al. (2020) note throughput bottlenecks below 100 TPS for IoT-integrated systems. Gálvez et al. (2018) identify consensus delays in permissionless setups.
Data Privacy Concerns
Immutable ledgers expose sensitive farm data, conflicting with regulations like GDPR (Feng et al., 2020). Tian (2016) reports privacy risks in centralized RFID-blockchain hybrids. Kamble et al. (2019) propose zero-knowledge proofs but note computational overhead.
IoT Interoperability Barriers
Heterogeneous sensors fail seamless blockchain integration, per Ayaz et al. (2019). Gálvez et al. (2018) cite protocol mismatches causing 20% data loss. Lezoche et al. (2020) stress standards gaps in Agri-food 4.0 architectures.
