TITLE: Validation Protocol of the Symmetry Logic (Closed Access) Date: March 9, 2026 Author: Thi Linh Vo This document serves as an official record of the successful identification and mathematical stabilization of the non-trivial zeros within the Riemann zeta function. The solution presented here is based on a proprietary black-box methodology. Non-Interactive Zero-Knowledge Proof (NIZK) Quantum-Biometric Mapping Nontrivial Zero Distribution This document presents a novel approach to the Riemann Hypothesis using a Biometric Symmetry Invariance. The solution is implemented via a Secure Black Box Model to protect the underlying Stationary Constants. By mapping biometric temporal data to the nontrivial zeros of the Zeta function, this work provides a verifiable framework for the proof while maintaining Algorithmic Integrity through a Zero-Knowledge approach
Electronic voting systems require satisfaction of security, transparency, and voter privacy to ensure fair and trustworthy election processes. Traditional centralized voting architectures suffer from limitations such as single points of failure, limited auditability, and vulnerability to data manipulation. This paper proposes a secure and decentralized electronic voting framework based on block chain technology to address these challenges. The proposed system integrates cryptographic authentication, role-based access control, smart contract automation, and distributed ledger storage to ensure tamper-resistant vote recording and transparent election management. The architecture employs a hybrid design combining secure database management for authentication with block chain-based transaction storage for immutable vote recording. Smart contracts enforce election rules, including voter eligibility verification, single-vote constraints, and automated vote tallying. Off-chain storage mechanisms are incorporated to improve scalability while maintaining data integrity by cryptographic hashing. Comprehensive testing, including unit, functional, integration, performance, and security evaluations, demonstrates reliable system operation and successful prevention of unauthorized access and duplicate voting attempts. Experimental results confirm that proposed framework provides secure vote handling, transparency, and auditability while preserving voter anonymity. The proposed approach offers a practical and scalable solution for next-generation decentralized electronic voting systems.

Blockchain has recently attracted significant attention, particularly for its potential to address major issues in traditional electronic voting such as limited transparency, centralized control, and vulnerability to tampering. In this research, it aimed to design and evaluate a blockchain-based electronic voting system that ensures voter privacy, increases transparency, and can efficiently manage large-scale elections. The proposed system adopts a modular, layered architecture featuring secure voter registration, authenticated vote casting, automated tallying, and public auditing. It operates on a permissioned blockchain, with smart contracts enforcing the necessary rules and validations. To maintain security, the system incorporates public-key encryption, cryptographic hashing, zero-knowledge proofs, and threshold cryptography. This combination guarantees ballot confidentiality, integrity, and non-repudiation for voters. For consensus, the system utilizes Practical Byzantine Fault Tolerance (PBFT). To evaluate performance, the conducted simulations that measured transaction latency, voting throughput, and scalability as participation increased. The findings revealed low latency, consistent throughput, and strong scalability, making the system suitable for both national-scale elections and smaller voting scenarios. In comparison to conventional e-voting platforms, this blockchain-based approach eliminates single points of failure, significantly reduces the risk of vote manipulation, and enables transparent auditing of the election process.

Global financial integrity is fundamentally challenged by cryptocurrency mixers such as Tornado Cash, which facilitate billions in illicit fund flows. Low detection rates, reliance on labeled training data that is unavailable for novel attacks, and failure to analyze temporal coordination patterns are all impediments to the effectiveness of existing forensic tools. We introduce CONSENSUS, a self-supervised heterogeneous ensemble framework that addresses the challenge of attribution in mixed transaction streams. Our system requires no pre-existing labels, and it generates supervision signals directly from on-chain behavioral patterns. It synthesizes evidence by orchestrating nine analytical modalitiesâincluding deterministic clustering, behavioral analysis, and multiple graph neural network architecturesâthrough a formal consensus mechanism. This multi-modal approach produces transparent, auditable risk scores from a 111-dimensional behavioral fingerprint. We validated the framework on five major decentralized finance (DeFi) exploits, including the Ronin Bridge and Poly Network hacks. Using raw transaction data, it detected all known primary attackers at 100% accuracy without training. Crucially, the framework's self-supervised components successfully identified the novel attack pattern of the Poly Network exploit, thereby demonstrating robustness to out-of-distribution threats that defeat supervised methods. By providing a transparent, zero-label solution, CONSENSUS establishes a new paradigm for flexible, effective risk profiling and forensic investigation.
FUNDAMENTAL LAW OF REALITY: TERNARY SYNTHESIS OF MATHEMATICS, PHYSICS, AND HISTORY Version 11.0 (Complete Synthesis with Structural Proof of Fermat's Last Theorem) This paper presents an algorithmic system discovered by the author during many years of analyzing price movements in financial markets. Four software modules written in MQL4 revealed a universal ternary hierarchical structure possessing Zâ-symmetry. From the code analysis, the fundamental group Zâ Ă Zâ, generating 9 basic relations, and the formula for the number of intersection points in the hierarchy, P = N â 2K, were derived. The discovered structure has proven to be universal across various fields of knowledge: Mathematics: Zâ Ă Zâ is isomorphic to a subgroup of SU(3) and the nilpotent ring â[x,y]/(xÂł, yÂł); the system's fractal dimension is D = log 3 / log 2 â 1.585. Number Theory: The synchronization parameter Ï = 0 at the non-trivial zeros of the Riemann zeta function is equivalent to the Riemann Hypothesis, numerically confirmed on 4153 zeros (100% match). Physics: Zâ Ă Zâ â SU(3) describes the color symmetry of Quantum Chromodynamics; the 9 compactification moduli of string theory correspond to the 9 system relations; the Ï = 0 state is interpreted as a transition to 11-dimensional M-Theory. History: Using an inverse problem method on 251 key dates, the reference points Tâ = â5502, Tâ = â5501, Tâ = â5500 were determined. The formula D = Tâ + 3k + s describes all key historical events. Four epochal points (â5502, â3315, â1128, 1059) mark shifts in civilizational cycles. Verification on over 12,000 dates and a blind test of 20 dates yielded 100% accuracy. Markets: On BRENT oil data (1998â2026), 4 convergence points (2005, 2011, 2018, 2025) were found with an 81-month interval, corresponding to the historical epochal points. Geopolitics: 20 key events of 2025 correspond 100% to the model's predictions for zones s=0,1,2. Fermat's Last Theorem: A structural explanation is derived through the formula P = N - 2K: for n > 2, the hierarchy depth K â„ 2 leads to a critical shortage of intersection points for synchronizing three independent circuits (x, y, z). A physical analogy is drawn with quark confinement in quantum chromodynamics. The cumulative statistical significance of all confirmations is p < 10â»âčÂłâ”, which excludes random coincidence. The system is fractally invariant and works identically at any time scale (from minute charts to millennia). The source code (4 MQL4 modules + Python implementation) is available upon request for non-commercial research under the CC BY-NC-ND 4.0 license. Keywords: ternary hierarchy, Zâ Ă Zâ, intersection points, Riemann Hypothesis, Fermat's Last Theorem, SU(3), string theory, M-theory, historical periodization, fractals, algorithmic realism, power law distribution, confinement.
We test price efficiency, which shows the fairness of trading for retail investors using the runs tests and variance ratio tests. We reject the hypothesis that Bitcoin prices are price efficient on most markets, but efficient on the Bitstamp BTC/USD. Coinbase departs from efficiency, indicating that fraud, later found by regulators, has significantly harmed retail investors. We also document barriers to trading of Bitcoin, which result in difficulties in arbitrage despite global price differences. My results predict the hack of the Bitfinex exchange, which caused it to close and harmed many people.
The rapid growth of decentralized finance (DeFi) has spurred innovation but also exposed blockchain systems to severe security threats. As of November 2025, cumulative losses from blockchain security incidents have exceeded${\$}$36.89 billion. Flash loan attacks account for 135 reported cases and rank fourth among all attack methods. Existing detection approaches either analyze contract source code, which is unavailable for many deployed contracts, or use transaction pattern matching tailored to specific scenarios, and therefore generalize poorly to diverse flash loan attacks. In this paper, we presentFlashShield, a general flash loan attack detection framework based on Hypergraph Neural Networks (HGNNs). We construct comprehensive datasets containing attack and benign transactions across multiple chains, and systematically analyze flash loan attack mechanisms along four DeFi protocol layers: code implementation, business logic, economic mechanisms, and cross protocol interactions.FlashShieldrepresents each transaction as a hypergraph of transfer actions and semantic relations, and employs a hybrid architecture that integrates spectral, spatial, and original features together with both node level and graph level representations. Experiments show thatFlashShieldimproves recall by 29% over leading methods and identifies 43 previously unknown malicious or suspicious activities (18 confirmed flash loan-related exploits and 25 suspected address poisoning incidents), demonstrating its effectiveness and scalability for automated DeFi security monitoring.
Cryptography and accounting have grown up alongside each other for more than five centuries without developing their similarities in dialogue. This extended concept note outlines a vision for a crossdisciplinary research programme integrating six philosophical dimensions: ontological, epistemological, axiological, teleological, praxiological and phenomenological. It explicates only the structural (ontological) dimension in detail, arguing that asymmetric verifiability (whereby the cost of engineering a false acceptance is deliberately set to exceed the cost of verifying a true one) is foundational to both disciplines: in cryptography to one-way functions, digital signatures and zero-knowledge proofs, and in accounting to conservatism in the Basu (1997) and Watts (2003) tradition. The remaining five dimensions are stated concisely and anchored to established literature on each side, with the lived practice of each craft identified as the least studied and the clearest opening for joint work, particularly in the context of post-quantum cryptography (PQC). The present contribution is the naming of the six-dimension structure rather than local novelty within any single dimension; prior scholarship has already placed Albertiâs cryptography and Pacioliâs bookkeeping within a common Renaissance tradition addressing trust at a distance. The note develops a role-to-treatment taxonomy and worked ledger illustrations (a TLS certificate issuance and two distinct quantum exposures: harvest-now-decrypt-later and trust-now-forge-later), and closes with a call for collaboration between cybersecurity and accounting researchers.
The integrity of electoral systems is fundamental to democratic governance; however, traditional voting mechanisms suffer from security vulnerabilities, lack of transparency, and accessibility constraints. This paper proposes a blockchain-based voting system leveraging distributed ledger technology to ensure secure, transparent, and tamper-resistant elections. The system integrates cryptographic techniques such as Zero-Knowledge Proofs (ZKPs) and Elliptic Curve Cryptography (ECC) within a permissioned blockchain framework using Hyperledger Fabric and Practical Byzantine Fault Tolerance (PBFT) consensus. A three-tier architecture consisting of Application, Blockchain, and Data Storage layers ensures scalability and efficiency. Security mechanisms including multi-factor authentication, end-to-end encryption, and AI-based anomaly detection mitigate potential threats such as Sybil attacks and denial-of-service attacks. Comparative analysis indicates improved security, transparency, and cost-effectiveness over traditional systems. The proposed framework demonstrates strong technical feasibility and provides a foundation for future advancements in digital electoral systems.
This study discovers a statistically and economically significant anomaly in Bitcoin performance-returns are, on average, 2.2% higher on major election days in G20 democracies on an exhaustive 2010-2024 sample that includes a full Bitcoin price history and 60 election events. This price appreciation is shown to be permanent, independent of the election outcome, and it is not accompanied by any significant prior or subsequent abnormal returns. The effect cannot be explained by conventional calendar anomalies or the Bitcoin halving cycle, and it is robust to alternative specifications and weighting schemes. The documented anomaly highlights the importance of cryptocurrencies in hedging political risks and presents a profitable trading opportunity for investors.

Online elections (e-voting) are fast and convenient. Still, there is growing concern that the democratic integrity of the election process is under threat due to problems such as cyberattacks, illegal intrusion, vote manipulation, and unclear verification of the results. Actual cases have demonstrated voter fraud, insecure data storage, and unreliable results, undermining the public's confidence in digital voting systems, particularly in primary national elections. Moreover, the traditional auditing system, which relies on paper ballots, manual logistics, and resource-intensive verification, results insignificant operational costs and a negative environmental impact. This paper proposes a solution to these capital challenges by introducing SECURE-VOTE_CHAIN, an open, secure e-voting platform that integrates a certified blockchain network, biometric verification checks, homomorphic encryption, and zero-knowledge public audit records. The blockchain nodes in this system, run by voting bodies and legitimate observers, consistently registered votes and facilitated decentralised consultation. Biometric authentication can exclude identity duplication and voter fraud, and only homomorphic encryption can ensure fair counting without knowing any votes provided by an individual. Zero-knowledge proofs also make public auditability achievable without reducing the anonymity of voters. The application of realistic election parameters in simulations yields an accuracy of 91.88, along with low confirmation latency and high attack resilience probabilities in the presence of insider attacks, replay attacks, and denial-of-service attempts. In addition to security and reliability, the system will eliminate paperwork and manual auditing, significantly reducing the carbon footprint of traditional elections. Altogether, SECURE-VOTE_CHAIN offers an environmentally friendly, secure, and scalable solution that is suitable for regaining voter confidence, ensuring electoral integrity, and creating a future-proof digital governance model. The model can be considered a reasonably helpful standard by which contemporary voting systems operate, as it combines technological benefits with the adequacy of achievements in terms of prospects, providing policymakers with dependable means of security and transparency in election procedures, applicable to both urban and rural settings.

Safe and transparent e-voting is becoming more and more important in modern democracies, as the confidence of citizens in electoral systems is determined by the issues of trust, privacy and scalability. Existing e-voting systems, however, have privacy, impersonation vulnerability, lack of transparency, and coercive weaknesses, and so they must be improved through cryptographic and identity solutions. In an attempt to provide security at these points, to propose a voting system that uses Aadhaar-linked decentralized identities together with iris scan biometrics to authenticate voters, zk-SNARKs to produce zero-knowledge proofs of voter eligibility without revealing their personal data, and homomorphic encryption to ensure ballot confidentiality and allow vote counting to be verifiably processed. Moreover, coercion resistance is ensured by a revoting mechanism, as only the last authenticated vote is included in the counting, thereby mitigating external pressure or vote-buying. The results demonstrate that the proposed design is capable to concurrently deliver strong authentication, biometric-based impersonation resistance, privacy preservation, end-to-end verifiability, and scalability in e-voting. In general, this framework eliminates major weaknesses of the old systems in addition to increasing voter confidence and integrity of the elections. The integration of decentralized identity, biometric iris recognition, and modern cryptography allows the model to provide a secure, transparent, and non-coercible framework of next-generation democratization procedures in India and can present an open-source, globally replicable solution with large-scale elections.

This research article provides the design of an in-person and remote voting system, while at the same time ensuring the privacy of users that would guarantee openness, transparency, and at the same time fraud-free results. The aim is to solve various common problems associated with most conventional elections including fraud, vote manipulation, through adaptation of the usage of a safe, highly transparent decentralized logical Hyperledger Fabric-based system provided by blockchain implementation. The methodology in this article is to be implemented for the sheer reason of urgency needed in making a more secure and transparent system for voting, considering even the rising frauds in elections. The addition of Zero Knowledge Proof (ZKP) guarantees that votes are confident and correct, yet anonymous between a voter and their vote. Biometric identification makes the system resistant to double spending. This incorporation of technologies ensures there is privacy and immutability against the double transactions, which, in turn, would be put in place as foundation for the future to be provided wherein every process in an election becomes safe and transparent. Innovation via creating a voting system to be trusted to meet today's demands and set standards for future electoral processes.

In response to the growing demand for secure and transparent digital elections, this paper presents a blockchain based Smart Election System that leverages advanced cryptographic and artificial intelligence techniques to ensure privacy, scalability, and verifiability. The proposed system integrates multi-factor authentication, Zero-Knowledge Proofs (ZKPs), smart contracts, and a sharded blockchain ledger to enable real-time, tamper-proof voting. Additionally, an Artificial intelligence based anomaly detection module monitors voting behaviour to flag suspicious patterns.Experimental evaluation demonstrates that the system achieves an average vote transaction latency of 1100ms with sharding, compared to 2800ms without it. The throughput increases from 130 to 220 votes/sec when sharding is enabled. ZKP integration ensures privacy at the cost of a moderate increase in validation time from 130ms to 230ms. The anomaly detection model, based on supervised learning, attained 92% precision, 88% recall, and an F1-score of 90%, ensuring proactive fraud detection. These results confirm the systemâs effectiveness in delivering a smart scalable, private, and trustworthy e-voting platform suitable for national and institutional elections.
