AI Components – The TrustMesh Intelligence Layer

Authra is not only a blockchain and network data platform, it’s also an AI-powered system. We often refer to Authra’s AI layer as “TrustMesh AI” – it is like the nervous system and immune system of the network, continuously learning from data and safeguarding integrity. Unlike many projects that might bolt on some machine learning as an afterthought, Authra has AI woven in from end to end. The AI components serve two broad purposes: 1) enhancing data quality and security (through anomaly detection, spoof resistance, etc.), and 2) extracting higher-level insights (like predictions and natural language querying) that add value to the raw data . Here are the key AI-driven features:

• On-Device TinyML: Each smartphone running the TruePing app carries a miniature AI agent that operates locally (on-device). We leverage TinyML models (lightweight neural networks and classifiers) that can run in real-time on a phone’s CPU or DSP with minimal battery draw. One crucial TinyML model is for spoof detection: it analyzes sensor data consistency to detect if someone is trying to fake a location or network metric. For example, if the phone’s GPS says it’s in London but the WiFi networks it sees have identifiers common to Paris, the model flags a potential anomaly. Or if a device claims a super fast network speed that is statistically out of range for its region and carrier, that could indicate manipulation. By filtering out obviously implausible data at the source, we save bandwidth and keep garbage data from ever hitting the network. Another on-device AI function is adaptive sampling using reinforcement learning: a tiny RL agent learns the optimal frequency to run tests based on context. If the user is stationary in a place with stable connectivity, the app can dial down test frequency to save battery. If the user starts moving or network quality fluctuates, the agent increases test frequency to capture those changes. Over time, this AI tunes data collection to be efficient yet responsive. These models can even personalize to each device (learning its typical sensor noise patterns, etc., to reduce false alarms). Importantly, running ML on-device also protects privacy – raw sensor readings need not be continuously uploaded; only the relevant derived insights (like “suspicious data, likely spoofed” or “network stable, skip test now”) are sent.

• Plausibility & Cross-Validation (Presence + QoE): We treat every data point as a hypothesis that must survive independent checks before it can influence rewards or analytics.

  • Local neighborhood corroboration: Each Presence/QoE report is compared with temporally- and spatially-adjacent reports. We compute a coherence score from agreement on radio context (cell IDs, Wi-Fi beacons), measured performance (latency/jitter/loss), and historical baselines for that area/time.

  • Plausibility priors: We down-weight reports that violate physical or operational constraints (e.g., implausible speed/location transitions; radio contexts inconsistent with claimed GPS; performance outliers that cannot be explained by diurnal/seasonal patterns).

  • Independence tests: We reduce influence from clusters that appear overly coordinated (same device models/OS builds, identical timing, identical network paths) to limit common-mode or Sybil bias.

Only reports with sufficient corroboration and plausibility progress to full reward weight and to enterprise analytics.

• Privacy-Preserving Behavioral Fingerprinting: To resist at-scale spoofing, we learn each device’s temporal signature of participation (cadence, motion/state transitions, radio context variety) using on-device RL/TinyML and backend summaries.

  • What it is (and is not): The fingerprint is a privacy-preserving statistical profile of how a device contributes—not an identity, biometric, or any personal attribute. It is computed from quantized locations, hashed SSIDs, and coarse timing windows.

  • Why it matters: Large Sybil farms struggle to replicate thousands of distinct, stable temporal signatures across weeks. Sudden drifts (e.g., many devices becoming perfectly periodic, or “teleporting” patterns) are flagged for quarantine/down-weighting.

  • User protections: Natural behavior changes (travel, device replacement) are handled with adaptive thresholds and warm-start models; users remain pseudonymous; raw precise locations never leave the device.

• Cloud Anomaly Detection & Sybil Defense: After data leaves the device and reaches Authra’s backend, a second layer of AI scrutiny kicks in. We use anomaly detection algorithms on the aggregated data streams to identify outliers or suspicious patterns that a single device might not catch. One technique employed early on is the Isolation Forest, an unsupervised model well-suited for high-dimensional anomaly detection. It looks at combinations of factors (location, time, latency, device type, etc.) and flags data that doesn’t fit the learned “norm”. For example, if suddenly a cluster of devices all report the exact same latency and coordinates (suggesting one script impersonating many phones), the anomaly detector would raise an alert. For combatting Sybil attacks – where an adversary might spin up many fake nodes or devices to flood the network – we incorporate graph analytics and graph neural networks. We model the relationships between devices, their co-locations, and their data similarity as a graph. Genuine users tend to have organic patterns (devices moving independently, data varying per environment) whereas a Sybil attack often has telltale signs (e.g., one controller coordinating many devices that might all appear together or alternate in suspicious ways). Using graph-based anomaly detection, we achieved >95% detection of Sybil nodes in simulation tests. Detected Sybils can be quarantined by the network (their data given low weight or ignored, their accounts possibly banned if severe). The anomaly detection models continuously retrain as more data flows in, meaning the system learns what normal network behavior looks like and can adapt to new attack tactics over time. Outputs from these AI systems can feed into device reputation scores (discussed next) or trigger requirements like needing additional validator confirmations for data that looks unusual. The AI here acts as an ever-vigilant sentry, more adaptive than any fixed rule set could be.

• Predictive Analytics (Outage & Performance Forecasting): One of Authra’s unique value propositions to enterprise customers is not just telling them what is happening now, but what will happen soon. We apply time-series forecasting models to the vast historical dataset of network metrics to predict future performance issues. Early on, we used models like XGBoost (a powerful gradient-boosting machine) on features such as recent latency trends, time of day, weather, and more. As data volume grew, we moved to advanced deep learning approaches – for example, LSTM networks and Temporal Fusion Transformers – which can capture seasonality and complex dependencies in the data. These models can forecast metrics like latency spikes or outage probabilities 24-72 hours ahead with impressive accuracy (in tests we achieved an AUC > 0.8 for predicting cell tower outages, meaning a high true-positive rate). A concrete example: the system might analyze all signals and output, “There is an 80% chance that mobile data latency in downtown area will exceed 200ms during 6-9pm tomorrow.” Terrascient will then surface this as an alert to operators or even an API output that a CDN can use to reroute traffic proactively. Over time, these predictions continuously validate themselves (the AI compares predicted vs actual and retrains), so the models get better. This predictive capability is a major differentiator against competitors that mostly offer reactive monitoring. Authra aims to give stakeholders a heads-up so they can fix problems before users feel pain.

• Reputation & Trust Graph: All data sources (devices, validators) in Authra maintain a reputation score computed by AI. We essentially build a web-of-trust graph where edges might represent corroboration or conflict between devices’ data. Factors influencing a device’s reputation include: 

  • consistency (does it usually agree with nearby devices’ observations?),

  • longevity (has it been contributing data reliably for a long time?), and

  • authenticity (has it passed attestation and anomaly checks consistently?)

We use graph neural networks (GNNs) to propagate trust across this network of interactions – a concept akin to Google’s PageRank but for sensor trustworthiness, or like how one might infer trust in a social network. This allows detection of more subtle attacks: e.g., if one bad actor controls many devices that mostly validate each other but rarely mix with others, the GNN can spot this “cluster” and mark them with lower trust. Devices with high reputation might serve as “anchor nodes” whose data is weighted more heavily or used as ground truth reference. Low-reputation devices might still be allowed to contribute (to avoid false negatives of banning honest but new users), but their data might require cross-checks or yields lower rewards until they build trust. The aim is a self-healing network: if someone injects bad data, the network isolates its influence quickly and prevents it from affecting any conclusions.

• Natural Language Query & Insights: To make the power of Authra’s data accessible to non-technical users, we incorporate Natural Language Understanding (NLU) in the Terrascient interface. Users (like a policymaker or an executive) can ask questions in plain English (or other languages) and get answers derived from the data. For example: “Which regions had the worst connectivity during the last storm?” or “Show me all areas in State X with average download speed below 5 Mbps last week.” The system uses NLU to interpret the question, then translates it to the appropriate database query or analytical computation and returns a human-friendly answer or visualization. This can be powered by fine-tuned language models or template-based NLP. Additionally, we use AI to generate automated insights and summaries. A GPT-like model might periodically produce a summary report such as: “Weekly Network Health: National uptime was 99.1%, with notable outages in Region Y due to storms; QoE improved 5% MoM overall.” These summaries save busy users from combing through dashboards and help highlight key events. While these front-end AI features don’t affect the core verification, they significantly improve user experience by turning raw data into digestible knowledge.

• User Engagement AI: Another AI aspect is keeping our contributor community active. We analyze user behavior (in aggregate and privacy-safe ways) to see how to improve retention. For instance, an AI model might learn the best time to send a notification: “You earned 5 $ATRX this week, check it out!” to encourage opening the app. If a usually active user goes quiet, the system could flag it and the app could proactively check if they need help (maybe a bug has occurred)  . We can personalize tips: if the model sees a user mostly on cellular data, it might suggest “connect to Wi-Fi to earn more” because Wi-Fi allows additional tests. These small AI-driven touches help maximize the contributor base – crucial for the network’s data coverage.

Collectively, these AI components form the TrustMesh AI layer – acting as both guardian and guide for the network. The AI is like an ever-improving filter and lens: it filters out bad data (immune system) and provides clarity and foresight from good data (brain). This combination of decentralized crypto incentives with AI analytics yields a network that gets smarter and more reliable with every data point collected. It creates a formidable moat: a competitor would not only have to replicate Authra’s network, but also its learned intelligence – which is always a moving target. Finally, by delivering near real-time insights and predictions at a fraction of the cost of traditional methods (thanks to community data and automation), Authra’s AI features help democratize high-quality infrastructure intelligence.

TrustMesh × Three-Layer Architecture: TrustMesh AI treats Layer 1 as the attestation boundary, Layer 2 as the evidence stream (PoP+QoE scoring, anomaly detection), and Layer 3 as transport policy (delay-tolerant prioritization and replay defense), keeping data quality high even in adversarial conditions. In Authra, Privacy (Pp), Tamper (Ts), and Continuity (Cp) are formalized as optional proof lanes of Yeggina proofs. Pp enforces redaction or differential-privacy policies (optionally with ZK proofs), Ts integrates device attestation/integrity signals, and Cp provides path commitments and kinematic plausibility to resist teleport/replay fraud.
