# Provider Description Microscopic changes in cells and connections can later contribute to a distributed memory, perception, or imagined scene. This paper asks how relations encoded at one physical scale can constrain patterns at another scale without requiring the brain to enlarge a microscopic trace into a literal copy. It separates dendritic morphology, network topology, temporal dynamics, and functional reinstatement, then asks whether finite-range scaling measurements add predictive or causal information beyond ordinary morphology, topology, activity history, oscillatory variables, single-scale models, and flexible nonlinear alternatives. The paper develops the historical Self-Aware Networks proposal called FRACTAL Conscious Perception as a testable cross-scale transformation rather than a claim that the brain is one ideal mathematical fractal. Four generations of synthetic applications test estimators, graph and temporal representations, capacity differences, route erasure, invertible transformations, exact matched restoration, nonspecific restoration, no-route controls, decoy shifts, and simpler single-scale alternatives. The record is deliberately mixed. Earlier systems contain favorable planted results, reversals, nulls, failed compensation, and a recovery statistic that could reward destructive collapse. A later frozen route-identification system passes all ten declared transformation, erasure, restoration, and refusal gates while still allowing raw ridge to perform slightly better and the correct single-scale model to win decisively when only one scale carries the target. The release includes the manuscript, six figures, frozen contracts, source and claim ledgers, raw and summary outputs, deterministic replays, tests, formal-verification receipts, and exact hashes. Seventeen Lean theorems establish bounded algebraic, rotation, and route-erasure invariants. They do not establish a biological neural mechanism or conscious experience. The applications use disclosed synthetic generators and do not constitute neural recordings, clinical evidence, or therapeutic guidance. The future biological evaluation remains sealed and unopened. ## Keywords fractal neuroscience; dendritic morphology; neural reinstatement; finite-range scaling; route identification; memory; connectome; multifractal dynamics; Self-Aware Networks; reproducibility

As autonomous AI agents gain the capacity to execute consequential actions in high-stakes domains -- medical prescribing, financial transactions, critical infrastructure control -- existing authorization mechanisms fail to answer a fundamental question: was the authorizing human genuinely conscious, uncoerced, and cognitively capable at the exact moment of authorization? Passwords, static biometrics, and digital signatures verify identity, not intent state. We present LICET (Latin: it is permitted), a middleware protocol that cryptographically binds AI agent authorization events to the real-time physiological state of the authorizing human via a three-layer architecture: (1) an identity anchor using ECG waveform morphology -- an anatomically determined signal resistant to pharmacological manipulation; (2) a liveness layer using continuous electrodermal activity (EDA) and overnight HRV pattern matching; and (3) a voluntary state layer using personalized Mahalanobis distance fusion across five physiological channels with pharmacological attack pattern detection. LICET additionally provides: per-event session-key derivation via HKDF; a Schnorr zero-knowledge proof over BN128, enabling third-party audit without exposing biometric data; a SHA-256 hash-chained ledger providing tamper-evident authorization records; and a four-level biometric trust hierarchy (L0-L3) aligned with IETF RATS architecture (RFC 9334). The protocol is designed as a coercion cost elevation mechanism: no single pharmacological intervention at survivable doses defeats the multi-signal fusion system. A reference implementation is publicly deployed at https://licet.dev.

This repository presents Harmonic Resonance Fields (HRF). This groundbreaking physics-informed machine learning framework fundamentally reimagines classification by modelling data points as damped harmonic oscillators generating class-specific wave interference patterns. Through 15 systematic algorithmic iterations and GPU-accelerated validation, HRF achieves 98.84% mean accuracy (±0.18% variance) on the OpenML 1471 EEG Eye State Corpus—establishing a new benchmark that surpasses Random Forest, XGBoost, and Extra Trees by 5-6 percentage points with statistical significance at p < 0.001. The Core Innovation: When AI Listens to Physics Traditional machine learning constructs decision boundaries through geometric partitioning—support vector machines identify hyperplanes, decision trees recursively split feature spaces, and neural networks learn nonlinear manifolds. HRF breaks this paradigm entirely by treating classification as a physical resonance problem: each training point emits class-specific waves that constructively or destructively interfere at query points, with classification determined by maximum resonance energy. The breakthrough: While conventional models struggle with temporal jitter (random time shifts in signals), HRF achieves mathematical phase invariance through spectral transformation. When Random Forest accuracy collapses from 94.67% to 60.00% under 2.0-second temporal shifts, HRF maintains 90.00% accuracy—a 30 percentage point advantage that stems from first principles, not empirical tuning.

This study introduces a functional EEG-based Multi-Factor Authentication (EEG-MFA) system engineered for accessibility and security utilizing affordable consumer hardware. Our version uses the BioAmp EXG Pill ( |3,000) with Arduino UNO, which is far cheaper than standard biometric systems that need expensive medical-grade equipment (|50,000–|500,000). It gets 86.7% authentication accuracy when the signal is good.The system uses three authentication factors: a password (knowledge), a pattern (behavior), and an EEG biometric (inherence). This makes it more secure. We utilize One-Class SVM with RBF kernel (nu=0.1) for user modeling, which means we don’t have to collect fake data, which is a big problem when using biometrics. The system learns brain patterns unique to each user using just 3–5 enrollment recordings (12 seconds each) and a simple electrode setup (3 electrodes: forehead + ears).Recent improvements in open-source EEG gear have made it much cheaper. With devices like the BioAmp EXG Pill (around 3,000 rupees), OpenBCI boards (100–500 dollars), and NeuroSky MindWave (100 dollars), students can do projects and small-scale research that weren’t possible before with medical-grade equipment. This lower price makes it possible to look into EEG authentication outside of established labs, utilizing real-world consumer technology that has its own problems. Some of the most important new features are: (1) an adaptive learning mechanism that lowers the False Rejection Rate from 20% to 0% over five sessions while keeping the False Acceptances at zero; (2) a tolerance margin system (10%) that makes up for differences in electrode placement; and (3) a complete end-to-end implementation with FastAPI backend, PostgreSQL database, and Next.js frontend.When we tested with real consumer hardware, we found that the most important performance aspect was signal quality (electrode preparation). With the right setup, we got an 80% genuine acceptance rate and a 0% imposter acceptance rate. The 10% Equal Error Rate (EER) is higher than medical-grade systems (¡5%), but it shows that it is possible to use it for specialized security applications, educational research, and proof-of-concept deployments where cost is more important than accuracy.

This project presents QoreChain, a novel Layer 1 blockchain architecture that addresses two critical challenges facing distributed ledger technology: vulnerability to quantum computing attacks and inefficient network resource allocation. As cryptographically relevant quantum computers are projected to emerge within 5-10 years, current blockchain infrastructures relying on elliptic curve cryptography face existential security threats. Simultaneously, existing networks struggle with scalability, cross-chain interoperability, and intelligent resource optimization. QoreChain introduces a quantum-native security architecture implementing ML-KEM (Kyber-1024) for post-quantum key exchange with migration pathways to Dilithium and Falcon signatures. Our hybrid classical-PQC bridge protocol enables seamless cryptographic migration without network disruption while maintaining backward compatibility—a capability absent in current blockchain platforms. Beyond quantum resistance, QoreChain integrates artificial intelligence at the protocol level through an Adaptive Intelligence Layer that performs dynamic transaction routing, predictive resource allocation, and cognitive consensus optimization, achieving demonstrable performance improvements: 5,914+ transactions per second with sub-second finality, 40% reduction in finality times during peak loads, and 60% reduction in cross-chain swap slippage through AI-driven liquidity positioning. The architecture comprises three synergistic innovations: (1) a multi-layer scalability framework with AI-driven chain selection routing transactions across main chain, sidechains, and paychains based on value and computational requirements; (2) the QoreChain Consensus Algorithm (QCA) extending Combined Proof of Stake with reputation-weighted validator selection and temporal consensus layering enabling parallel consensus sessions across different time horizons; and (3) comprehensive developer tooling including natural language smart contract generation with cross-chain compilation, automated vulnerability detection using predictive AI, and voice-first accessibility features. We demonstrate QoreChain's practical applicability through integration specifications for enterprise environments (financial services, defense, healthcare), IoT deployments with hardware-optimized lightweight cryptography for resource-constrained devices, and universal cross-chain connectivity supporting Ethereum, Solana, TON, BSC, Avalanche, and Cosmos ecosystems via IBC, LayerZero, and proprietary protocols. Performance benchmarks, security proofs, and economic sustainability models validate QoreChain's viability as future-proof blockchain infrastructure for the post-quantum era.Abstract content goes here

Brain–Computer Interfaces (BCIs) represent a transformative paradigm in human–machine interaction, enabling direct communication between neural signals and external devices. They hold immense promise in domains such as medical neuroprosthetics, defense communication, and immersive gaming. However, the neural data they process is highly sensitive, and current BCI frameworks that rely on centralized servers and traditional encryption are vulnerable to data breaches, manipulation, and the emerging threats of quantum decryption. These limitations highlight the urgent need for secure, privacy-preserving, and resilient architectures for BCI communication. To address these challenges, this paper introduces NeuroGuard, a blockchain-based framework enhanced with Post-Quantum Cryptography (PQC) algorithms—CRYSTALS-Kyber for secure key exchange and Dilithium for digital signatures—combined with Zero-Knowledge Proofs (ZKPs) for lightweight device authentication. Neural data packets are logged in a decentralized ledger, ensuring immutability, transparency, and tamper-proof communication. A prototype system was implemented using an EEG-based BCI headset with edge preprocessing and blockchain-secured communication. Experimental results demonstrate a 31% improvement in attack resistance, 22% reduction in latency, and complete removal of central points of failure compared to traditional BCI security models. The novelty of NeuroGuard lies in integrating PQC, blockchain, ZKPs, and edge intelligence into a unified BCI security architecture, paving the way for future quantum-resilient neural communication systems.

Blockchain technology has revolutionized decentralized systems, with applications that span finance, healthcare, and supply chain management. However, scalability challenges, particularly limited transaction throughput and high computational overhead, hinder its broader adoption. This work presents and validates a machine learning-driven consensus mechanism to enhance scalability while preserving security and decentralization. The proposed approach dynamically adjusts the mining difficulty and resource allocation in real time by employing Bayesian-optimized ensemble models (XGBoost and Random Forest) to predict the conditions of the blockchain network. Experimental evaluations show improved throughput, lower latency, and more equitable miner participation compared to traditional Proof of Work (PoW). The findings suggest that data-driven consensus can mitigate long-standing performance bottlenecks, enabling next-generation decentralized systems for industrial-scale deployment.

ABSTRACT Introduction The popularization of blockchain‐based applications made evident a critical challenge, namely the inherent isolation of these decentralized systems, akin to the disconnected and technologically diverse local area networks of the 1970s. This lack of interoperability limits the potential for widespread adoption and innovation in the blockchain space. While various initiatives aim to bridge this gap, many remain nascent. Methods This article addresses this issue by proposing a robust architecture and practical implementation to interconnect two Ethereum‐based blockchains, enabling seamless smart contract interactions across these chains, and facilitating the exchange of complex information beyond mere token transfers. Results Our work explores the emerging landscape of inter‐blockchain communication, highlighting their current maturity and potential, and providing insights on how to overcome the technical hurdles associated with these protocols, particularly in the context of transmitting complex data and executing cross‐chain function calls. Additionally, we illustrate with a case study the challenges posed by linking private blockchains with public ones, ensuring secure and efficient data exchange. Conclusion This article aims to inspire blockchain researchers and practitioners, presenting a foundational framework for enhancing blockchain interoperability, including detailed, practical steps for its implementation. By laying the groundwork for more connected blockchain ecosystems, we intend to support the continued evolution and widespread adoption of blockchain technology.

The objective of this proof-of-concept study was to test the utility of NeuroTargeted Training (NTT), a new method using functional Near-Infrared Spectroscopy (fNIRS) to measure and enhance cognitive performance during simulator training. Traditional simulator training is limited to behavioral evaluations, without capturing the trainee's internal cognitive processes. NTT addresses this gap by comparing trainees’ brain activation patterns to those of experts, allowing for precise identification and remediation of cognitive performance gaps. Three studies were conducted with five participants. Expert neural benchmarks were established from a man overboard simulation. Novices were evaluated against these benchmarks using a Expert Reference Index (ERI), quantifying deviations from expert performance, and the NeuroTargeted Training methodology was compared with conventional evaluations. Personalized training, based on identified gaps, was conducted to align novice neural patterns with expert benchmarks. Significant differences were observed, particularly in the anterior insula and inferior frontal gyrus, with an ERI of 4.84. Cohen’s Kappa (.69) indicated moderate inter-rater reliability. Subsequent targeted training reduced the ERI by 27%, aligning novice neural patterns with experts. Without intervention, the ERI rose by 79%, indicating increased cognitive strain. These findings highlight NTT’s potential to enhance learning outcomes in high-stake exercises by providing insights into cognitive processes.

With the rapid development of Decentralized Finance (DeFi) and Real-World Assets (RWA), the importance of blockchain oracles in real-time data acquisition has become increasingly prominent. Using cryptographic techniques, threshold signature oracles can achieve consensus on data from multiple nodes and provide corresponding proofs to ensure the credibility and security of the information. However, in real-time data acquisition, threshold signature methods face challenges such as data inconsistency and low success rates in heterogeneous environments, which limit their practical application potential. To address these issues, this paper proposes an innovative dual-strategy approach to enhance the success rate of data consensus in blockchain threshold signature oracles. Firstly, we introduce a Representative Enhanced Aggregation Strategy (REP-AG) that improves the representativeness of data submitted by nodes, ensuring consistency with data from other nodes, and thereby enhancing the usability of threshold signatures. Additionally, we present a Timing Optimization Strategy (TIM-OPT) that dynamically adjusts the timing of nodes' access to data sources to maximize consensus success rates. Experimental results indicate that REP-AG improves the aggregation success rate by approximately 56.6\% compared to the optimal baseline, while the implementation of TIM-OPT leads to an average increase of approximately 32.9\% in consensus success rates across all scenarios.

The robust subgroup multisignature allows any subgroup of signers to generate a multisignature on behalf of the whole group, which can be flexibly applied in many blockchain consensus mechanisms. Unlike the security model of traditional subgroup multisignatures, robustness can prevent dishonest signers from joining a subgroup by checking each individual signature before combining. To enhance the robustness of subgroup multisignatures, we utilize an on-chain smart contract instead of an off-chain combiner to check each individual signature. We propose a blockchain-assisted robust subgroup elliptic curve digital signature (ECDSA) multisignature scheme and prove its robustness and unforgeability. Since the ECDSA signature is the most popular signature used for blockchains and some blockchain platforms, such as Ethereum, already have a precompiled contract for the verification of the ECDSA, the on-chain costs for each single ECDSA signature are very low. Experiments show that our blockchain-assisted subgroup ECDSA multisignature has efficient on-chain costs. On the other hand, multiplicative-to-additive (MtA) protocols are used in the construction of subgroup multisignatures, which results in increased communication and computational costs. We use two popular additive homomorphic encryption scheme (Paillier and Castagnos and Laguillaumie)-based MtA protocols to construct our scheme and test its performance. Finally, we apply our scheme in a consensus mechanism of a distributed blockchain interoperability oracle.

Blockchain networks use consensus mechanisms so that participants can exchange transactions without the need to rely on a trusted third party. Consensus mechanisms using Proof of Work burn significant energy to select a block miner, and this delay limits performance. Other consensus mechanisms such as Proof of Stake or Practical Byzantine Fault Tolerance still designate a single validator to append a block to the chain, preventing blocks from being built and published in parallel. In this article, we introduce a new consensus mechanism, Proof of Descriptor, enabling clients to work together to publish blockchain transactions using a descriptor object which stores information on the cooperative parallel execution of transactions. Proof of Descriptor consensus allows commutative transactions to be mined concurrently. It does not require a single leader to append transactions to the ledger, enabling clients to cooperate on publishing transactions. We also propose a novel graph-based ledger with multiple entry points to facilitate the scalability of Proof of Descriptor, as well as a secure hashing scheme to resist long-range attacks. We demonstrate that our approach is as secure as related works with respect to a malicious leader, 51% attack, and other known blockchain vulnerabilities. Furthermore, our experimental evaluation shows that our approach scales with the size of the network, experiencing up to a 4 \(\times\) improvement in throughput over the fastest sequential blockchain, Solana .

This work is to present a new approach – the Resource Allocation Weighted Random Walk (RA-WRW) algorithm, based on IOTA-Distributed Ledger Technology (DLT), for the optimization of transaction processing within the IOTA network. The objectives of improved execution time, better CPU usage, enhanced network efficiency, and better scalability are met in accordance with stringent security measures. The Python-based algorithm considers node resources and transaction weights for the selection of the best tips. The authentication operation of the sender with private keys ensures the integrity of the data, while verification procedures confirm the authenticity of the tips and the validity of transactions. Implementation of this algorithm greatly improves the efficiency of IOTA network transaction processing. The experiment is run on a commonly used dataset available in Kaggle and some system-specific configurations, which depicts a significant improvement in execution time, CPU usage, network efficiency, and scalability. The tips selected are very authentic and consistent, thus proving the efficacy of this algorithm. It proposes a new RA-WRW algorithm based on IOTA-DLT, efficiently fusing resource allocation with weighted random walk strategies for improving the security, efficiency, and scalability in distributed ledger transactions. This has been a colossal development toward the betterment of processing transactions across the IOTA network and feels the pulse of such a newer approach in applications across the real world.

Blockchain is recognized for its robust security features, and its integration with Internet of Things (IoT) systems presents scalability and operational challenges. Deploying Artificial Intelligence (AI) within blockchain environments raises concerns about balancing rigorous security requirements with computational efficiency. The prime motivation resides in integrating AI with blockchain to strengthen IoT security and withstand multiple variants of lethal threats. With the increasing number of IoT devices, there has also been a spontaneous increase in security vulnerabilities. While conventional security methods are inadequate for the diversification of IoT devices, adopting AI can assist in identifying and mitigating such threats in real time, whereas integrating AI with blockchain can offer more intelligent decentralized security measures. The paper contributes to a three-layered architecture encompassing the device/sensory, edge, and cloud layers. This structure supports a novel method for assessing legitimacy scores and serves as an initial security measure. The proposed scheme also enhances the architecture by introducing an Ethereum-based data repositioning framework as a potential trapdoor function, ensuring maximal secrecy. To complement this, a simplified consensus module generates a conclusive evidence matrix, bolstering accountability. The model also incorporates an innovative AI-based security optimization utilizing an unconventional neural network model that operates faster and is enhanced with metaheuristic algorithms. Comparative benchmarks demonstrate that our approach results in a 48.5% improvement in threat detection accuracy and a 23.5% reduction in processing time relative to existing systems, marking significant advancements in IoT security for smart cities.

Cognitive Radio Network uses the available spectrum resources wisely. Spectrum sensing is the central element of a cognitive radio network. However, spectrum sensing is susceptible to multiple security breaches caused by malicious users. These attackers attempt to change the sensed result in order to decrease network performance. In our proposed approach, with the help of Blockchain-based technology, the fusion center is able to detect and prevent such criminal activities. The method of our model makes use of blockchain-based malicious user detection with SHA-3 hashing and energy detection-based Spectrum sensing. The detection strategy takes place in two stages: Block updation phase and iron out phase. The simulation results of the proposed method demonstrate 3.125%, 6.5% and 8.8% more detection probability at -5 dB SNR in the presence of malicious users, when compared to other methods like equal gain combining (EGC), blockchain based coperative spectrum sensing (BCSS) and fault-tolerant cooperative spectrum sensing (FTCSS) respectively. Thus, the security of cognitive radio blockchain network is proved to be significantly improved.

Abstract This study analyzes the security implications of Proof-of-Work blockchains with respect to the stale block rate and the lack of a block verification process. The stale block rate is a crucial security metric that quantifies the proportion of rejected blocks in the blockchain network. The absence of a block verification process represents another critical security concern, as it permits the potential for invalid transactions within the network. In this article, we propose and implement a quantitative and analytical model to capture the primary operations of Proof-of-Work blockchains utilizing the Performance Evaluation Process Algebra. The proposed model can assist blockchain designers, architects, and analysts in achieving the ideal security level for blockchain systems by determining the proper network and consensus settings. We conduct extensive experiments to determine the sensitivity of security to four aspects: the number of active miners and their mining hash rates, the duration between blocks, the latency in block propagation, and the time required for block verification, all of which have been shown to influence the outcomes. We contribute to the findings of the existing research by conducting the first analysis of how the number of miners affects the frequency of stale block results, as well as how the delay in block propagation influences the incentives received by rational miners who choose to avoid the block verification process.
