# Security

TAC implements a comprehensive security framework with multiple layers of protection, professional audits, and continuous monitoring to ensure the safety of hybrid dApps and user assets.

## Multi-Layer Security Architecture

TAC's security model operates across multiple layers to provide comprehensive protection for users and applications.

### TON Adapter Security

The TON Adapter implements distributed architecture with multiple validation layers:

<AccordionGroup>
  <Accordion title="Distributed Architecture" icon="network">
    **Current State**: TON Adapter operates with distributed sequencer groups
    providing redundancy.

    **Future Decentralization**: Architecture designed for progressive decentralization as the network matures.
  </Accordion>

  <Accordion title="Consensus" icon="handshake">
    **Multi-Group Validation**: Cross-chain messages require consensus from
    multiple independent sequencer groups.

    **Economic Stakes**: Sequencers stake collateral to participate in validation, creating financial incentives for
    honest behavior.

    **Cryptographic Proofs**: All cross-chain operations protected by Merkle proofs and cryptographic verification.
  </Accordion>

  <Accordion title="Rollback" icon="undo-2">
    **Asset refund**: Automatic refund of locked assets if cross-chain transaction fails for any reason.
  </Accordion>
</AccordionGroup>

It also provides economic security:

<Accordion title="Stake Requirements" icon="coins">
  **Every sequencer group must stake collateral:**

  * Minimum stake set by DAO governance
  * Higher stakes earn proportionally higher rewards
  * Stake must remain above threshold during participation
  * Partial stake locking during proof submission
</Accordion>

<Accordion title="Reward Distribution" icon="chart-line">
  **Performance-based incentives:**

  * Rewards distributed proportionally to stake size
  * Executor selection based on collateral weight
  * Commission sharing within groups
  * Penalty mechanisms for incorrect operations
</Accordion>

<Accordion title="Governance & Elections" icon="vote">
  **Democratic group selection:**

  * New groups approved through DAO voting
  * Regular election cycles (DAO configurable)
  * Performance monitoring and rating systems
  * Penalty applications and network-wide voting
</Accordion>

### EVM Layer Security

TAC EVM undergoes comprehensive security audits by industry-leading firms to ensure the highest security standards.
You can review the completed ones on [this page](/audit/overview).
New reports will appear as the protocol evolves and new features are added.

<AccordionGroup>
  <Accordion title="Cancun Network Foundation" icon="ethereum">
    **Modern EVM Implementation**: TAC EVM is based on the Cancun upgrade,
    incorporating the latest Ethereum security improvements and optimizations.

    **Proven Technology**: Built on battle-tested EVM specifications with all
    security features and protections of modern Ethereum networks.

    **Standard Compliance**: Full compatibility with Ethereum security models ensures
    familiar security guarantees for developers.
  </Accordion>

  <Accordion title="Delegated Proof of Stake (dPoS)" icon="coins">
    **TAC Token Security**: Network consensus secured by delegated Proof of Stake
    using \$TAC tokens as the staking mechanism.

    **Validator Incentives**: Economic incentives align validator behavior with network security through staking
    rewards and slashing penalties.

    **Distributed Validation**: Multiple independent validators secure the network through distributed consensus
    mechanisms.
  </Accordion>
</AccordionGroup>

## Continuous Monitoring

TAC implements 24/7 security monitoring and incident response capabilities to detect and respond to potential threats.

### Real-Time Threat Detection

<AccordionGroup>
  <Accordion title="Hypernative Monitoring" icon="radar">
    **24/7 Security Monitoring**: Hypernative provides continuous monitoring of
    TAC networks, detecting potential exploits and anomalous behavior.

    **Mempool-Level Detection**: Advanced monitoring capabilities detect
    suspicious transactions at the mempool level before they're executed.

    **Real-Time Alerts**: Immediate notifications for potential security threats
    enable rapid response and mitigation.
  </Accordion>

  <Accordion title="Dedicated SOC Team" icon="users">
    **24/7 Security Operations**: Fully dedicated Security Operations Center
    (SOC) team monitoring TAC infrastructure around the clock.

    **Incident Response**: Trained security professionals ready to respond to any security
    incidents or threats.

    **Proactive Monitoring**: Continuous analysis of network activity and security metrics to identify potential issues before
    they become problems.
  </Accordion>
</AccordionGroup>

## Future Enhancements

TAC has planned significant security upgrades that will provide additional layers of protection and decentralization.

### FROST Consensus Upgrade

<Tip>Already live on TAC Testnet!</Tip>

Planned migration to **FROST-Ed25519** threshold signatures with Distributed Key Generation (DKG).

<Tabs>
  <Tab title="Threshold Security">
    **Enhanced Cryptographic Security:**

    * Threshold signature creation requires `t+1` out of `n` participants
    * Attackers controlling up to `t` participants cannot forge signatures
    * **Ed25519** compatibility with existing verification systems
    * Round-optimized design minimizes communication overhead
  </Tab>

  <Tab title="Distributed Key Generation">
    **Decentralized Key Management:**

    * Dealerless key generation - no single party knows complete secret
    * High threshold support `(k > n/2)` for enhanced security
    * Feldman VSS with verifiable encrypted shares
    * Complaint handling without secret disclosure
  </Tab>
</Tabs>
