Printing Protocol: Physical ZKPs for Decomposition Puzzles

New Generation Computing
AbstractDecomposition puzzles are pencil-and-paper logic puzzles that involve partitioning a rectangular grid into several regions to satisfy certain rules. In this paper, we construct a generic card-based protocol called printing protocol, which can be used to physically verify solutions of decompositon puzzles.

Blockchain‐Based Secure Data Sharing for IoT Devices Using Smart Contracts: A Systematic Review and Taxonomy

IET Blockchain, Volume 6, Issue 1, January/December 2026.
ABSTRACT The proliferation of Internet of Things (IoT) devices has created an urgent demand for secure, scalable and interoperable data‐sharing architectures. Centralized paradigms exhibit single points of failure, inadequate access control and limited transparency, rendering them structurally misaligned with the distributed nature of IoT deployments ...

Operating ZKPs on Blockchain: A Performance Analysis Based on Hyperledger Fabric

2024 IEEE International Conference on Decentralized Applications and Infrastructures (DAPPS)
Preserving privacy in blockchain-based systems is crucial for ensuring anonymity and confidentiality during transactions. While cryptographic solutions can address on-chain privacy concerns, their implementation on blockchains may introduce performance overhead, which remains unclear to researchers and practitioners.

A Blockchain‐Based Privacy Protection Scheme for Bidding Transactions Supporting Threshold Traceability

IET Blockchain, Volume 6, Issue 1, January/December 2026.
ABSTRACT Bidding transactions are widely used in scenarios such as government procurement and corporate tendering. However, while traditional blockchain achieves transparency in transactions, it also poses a risk of sensitive information such as bidder identity, quotation, and time being leaked, thereby undermining the fairness and compliance of ...

Erasure‐Coded Sharding and Proof‐of‐Storage for Practical Blockchain Trilemma Balance

IET Blockchain, Volume 6, Issue 1, January/December 2026.
The proposed storage‐first blockchain framework resolves the blockchain trilemma by synergistically combining decentralised storage, zero‐knowledge proofs and sharded proof‐of‐storage consensus. Empirical evaluation demonstrates a peak throughput of 2800 transactions per second with low latency and strong Byzantine fault tolerance, while substantially ...
