Application Scenarios

AetherSec is designed to address diverse real-world needs within the blockchain ecosystem. Below are specific applications in user protection, contract security, and network defense, showcasing the practical value of AI and blockchain synergy.

User Asset Protection

Need

Users frequently lose private keys and assets to phishing attacks or malicious DApps, lacking real-time protective tools.

AetherSec Solution

- Real-Time Alerts: Aether Guardian monitors wallet transaction patterns, issuing immediate warnings via DApp or push notifications if anomalies (e.g., large transfers to unknown addresses) are detected.

- Phishing Detection: AI analyzes the historical behavior of transaction target addresses, leveraging on-chain blacklists and community-submitted intelligence to identify potential phishing risks.

- Automated Intervention: If threat confidence exceeds a threshold (e.g., 90%), smart contracts temporarily lock the user’s account to prevent fund loss, unlockable via multi-factor verification.

Case Study

A user attempts to transfer 10 ETH to a newly registered address. Aether Guardian detects a match with known phishing patterns, pauses the transaction, and prompts verification, successfully averting a loss.

Smart Contract Security

Need

Smart contract vulnerabilities (e.g., reentrancy attacks, overflow errors) pose major risks to DeFi projects, with traditional audits being costly and unable to cover runtime threats.

AetherSec Solution

- Pre-Deployment Checks: AI scans contract bytecode to identify common vulnerabilities (e.g., unchecked external calls), generating risk reports for developers to optimize.

- Runtime Monitoring: Aether Guardian analyzes contract call data in real time, detecting anomalous behavior (e.g., repeated function calls) and pausing execution via smart contracts.

- Vulnerability Intelligence Sharing: Community-submitted vulnerability samples are stored in a decentralized database, enhancing AI detection accuracy.

Case Study

A DeFi contract is targeted due to a reentrancy flaw. Aether Guardian detects abnormal Gas consumption, triggers a smart contract to restrict calls, mitigates potential losses, and alerts developers for a fix.

Network-Level Defense

Need

Blockchain networks face threats like Sybil attacks and 51% attacks, with traditional defenses relying on centralized monitoring and lacking distributed response capabilities.

AetherSec Solution

- Node Behavior Analysis: AI monitors network nodes’ transaction broadcasts and block validation activities, identifying patterns of spoofed identities or malicious nodes.

- Threat Isolation: Upon detecting suspicious nodes, smart contracts adjust consensus weights or temporarily isolate them from the network, logging actions on-chain.

- Attack Early Warning: Analyzes network-wide hashrate distribution and transaction patterns, alerting node operators and users to signs of hashrate concentration (e.g., 51% attack precursors).

Case Study

A network sees a surge of new nodes attempting to dominate consensus. Aether Guardian flags it as a Sybil attack, and smart contracts reduce their voting power, preserving network stability.

Cross-Chain Security Bridging

Need

Cross-chain bridges, due to the complexity of asset transfers, are prime targets for hackers, requiring consistent security across multiple chains.

AetherSec Solution

- Cross-Chain Monitoring: Aether Guardian operates across multiple chains (e.g., Ethereum and Polygon), verifying cross-chain transaction integrity (e.g., amount matching, signature validation).

- Anomaly Interception: If a forged cross-chain request (e.g., duplicate withdrawals) is detected, smart contracts pause bridging operations and record evidence.

- Inter-Chain Collaboration: Uses blockchain oracles to share threat intelligence, ensuring unified defense across the cross-chain ecosystem.

Case Study

A hacker exploits a cross-chain bridge flaw to attempt repeated asset withdrawals. Aether Guardian detects the anomalous pattern, triggers a smart contract to lock the bridge, and prevents losses.
