1. Introduction

BECAS (Blockchain Enabled Community Assurance System) is a decentralized security protocol designed to protect Web3 communities on Discord. By leveraging advanced AI analysis, cross-server reputation tracking, and immutable blockchain records, BECAS creates a safer environment for users and projects alike.

The current state of Discord security is fragmented. Scammers move freely between servers, and moderation tools lack the context to identify sophisticated threats. BECAS solves this by creating a unified trust layer that follows users across the entire ecosystem.

Our mission is to build the standard for trust in the decentralized web, ensuring that community interactions are safe, transparent, and verifiable.

2. Problem Statement

Key challenges facing Discord communities today include:

• Fragmented Data: Security insights are siloed within individual servers, preventing a coordinated defense against bad actors.
• Sophisticated Scams: Social engineering attacks, such as impersonation and phishing, often bypass simple keyword filters used by traditional bots.
• Lack of Accountability: Bad actors can create infinite new accounts with zero reputation cost, making bans ineffective as a long-term deterrent.
• Trust Deficit: Users have no easy way to verify the legitimacy of other members or projects, leading to skepticism and lower engagement.

3. The BECAS Solution

BECAS introduces a holistic approach to community security, built on three core pillars that work in synergy to provide comprehensive protection:

3.1 How It Works

When a user joins a BECAS-protected server, their Trust Score is instantly retrieved. If they have a history of violations in other servers, the system can automatically flag them, restrict their permissions, or ban them outright.

Simultaneously, our AI engine analyzes every message in real-time. It looks beyond simple keywords to understand context, intent, and sentiment. If a user attempts a scam, the AI detects it, removes the message, and updates the user's global Trust Score, protecting all other servers in the network.

4. The Trust Score Algorithm

At the heart of BECAS is the Trust Score, a dynamic value ranging from 0 to 100 that represents a user's reputation. The score is calculated using a weighted algorithm that considers multiple factors to ensure accuracy and fairness.

4.1 Score Tiers

• 90-100 (Elite): Verified users with long history and no violations.
• 70-89 (Trusted): Active users with good standing.
• 50-69 (Neutral): New users or those with minor infractions.
• 30-49 (Suspicious): Users with recent warnings or suspicious patterns.
• 0-29 (High Risk): Confirmed scammers or repeat offenders.

5. BecasFlow Technology

BecasFlow is our proprietary AI orchestration engine, designed specifically for high-speed, context-aware moderation. Unlike generic LLM wrappers, BecasFlow uses a multi-model architecture to deliver responses in milliseconds.

5.1 Multi-Model Architecture

BecasFlow utilizes a tiered AI approach:

• Layer 1 (Reflex): Instant pattern matching for known scams and spam (0.1s).
• Layer 2 (Analysis): Lightweight LLM for context and sentiment analysis (1-2s).
• Layer 3 (Reasoning): Advanced LLM (GPT-4/Claude) for complex decision making and edge cases (3-5s).

6. Blockchain Integration

BECAS leverages the Base Layer 2 blockchain to create an immutable record of trust. This ensures transparency and prevents data manipulation.

6.1 On-Chain Events

The following events are recorded on-chain:

• Violations: When a user is banned for a serious offense (scamming), a record is minted.
• Appeals: If a user successfully appeals a ban, the record is updated.
• Verifications: Wallet linking and identity verification events.

6.2 Why Base?

We chose Base for its low transaction fees, high speed, and strong security guarantees inherited from Ethereum. This allows us to process high volumes of moderation events without incurring prohibitive costs.

9. Conclusion

BECAS is not just a bot; it's a paradigm shift in how we approach online safety. By combining the speed of AI with the immutability of blockchain, we are creating a trust layer for the internet that is transparent, fair, and effective.
