Blockchain privacy and regulatory compliance: Towards a practical equilibrium

Blockchain: Research and Applications
We study Privacy Pools, a novel smart contract-based privacy-enhancing protocol. The protocol introduces a mechanism for users to reveal certain properties of their transaction without having to reveal the transaction itself.

Similarity‐Enhanced Representation Learning of Non‐Canonical Amino Acids for Therapeutic Peptide Modeling

Advanced Science, EarlyView.
Non‐canonical amino acids (ncAAs) enhance peptide therapeutics but remain difficult to model computationally. SinCAA, a similarity‐enhanced pretraining framework, jointly optimizes contrastive learning guided by a novel conformational similarity metric with masked node reconstruction, capturing both functional relationships and chemical identity of ...

Efficient Zero-Knowledge Proofs of Knowledge Without Intractability Assumptions

, 2000
We initiate the investigation of the class of relations that admit extremely efficient perfect zero knowledge proofs of knowledge: constant number of rounds, communication linear in the length of the statement and the witness, and negligible knowledge ...

Research on transaction privacy protection solutions for cross‐border commerce

IET Blockchain
In response to the dual privacy protection challenges concerning the confidentiality of transaction amounts and identities in cross‐border trade, a transaction scheme that combines +HomEIG Zero Knowledge Proof (+HomEIG‐ZKProof) and the national ...

On the Concrete Complexity of Zero-Knowledge Proofs

, 1990
The fact that there are zero-knowledge proofs for all languages in NP has, potentially, enormous implications to cryptography. For cryptographers, the issue is no longer "which languages in NP have zero-knowledge proofs" but rather "which ...

Mechanophore‐Based Multichannel Colorimetric Force Sensors: Ultrasound‐Driven Stress and Strain Quantification

Advanced Science, EarlyView.
ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...

A brief survey of zero-knowledge proofs

, 1992
: "In cryptography, the notion of zero-knowledge is important. It is also related to complexity theory. In this paper we briefly survey the zero-knowledge proofs in the literature.

Synthetic Shewanella‐Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium‐Ion Batteries Using Brewing Wastewater as Leaching Agent

Advanced Science, EarlyView.
A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.
