# Decentralized Asset Verify Layer

The Decentralized Asset Verify Layer (DAVL) plays a crucial role in DuckChain architecture, enabling the flow of assets and information between different blockchain networks.

1. Invoke Bridge Services: Users or smart contracts invoke Bridge services to facilitate interactions between the TON Chain and DuckChain, promoting communication between different blockchain networks.
2. Asset Transfer: Users can initiate asset transfer requests on the TON Network and transfer them to the DuckChain Network through Bridge services, enabling cross-chain asset flow.
3. State Synchronization: Bridge services ensure that the state of the DuckChain Network is synchronized with the TON Network, guaranteeing data consistency and accuracy.
4. Multisignature Confirmation: Requires Proposers and Reviewers to be validated through a multi-signature mechanism, increasing security and preventing single points of failure and malicious attacks.
5. Transaction Completion: Once a transaction is confirmed on the TON Network, the corresponding operation is also completed on the DuckChain Network, ensuring transaction finality and consistency.
6. Decentralized Operation: The entire process remains decentralized with no single control point, enhancing system security and tamper resistance.

DAVL has the following innovative features:

* Proposal and Review Process: Introduces a rigorous proposal and review mechanism before executing cross-chain transactions, ensuring the rationality and security of each transaction, and reducing risks.
* Multisignature Wallet: Employs a multisignature mechanism to ensure transactions require confirmation from multiple signers, providing an extra layer of security and effectively preventing single points of failure and malicious attacks.
* Asset Liquidity: Supports asset transfer functions between TON and other blockchain networks, enhancing asset liquidity and providing users with a wider range of investment options.
* Information Interchange: Enables the exchange of information and data between different blockchain networks, promoting interoperability between networks and enhancing synergies.
* DApp Interoperability: Supports the interoperability of decentralized applications (DApps) across different blockchain platforms, offering users more diverse application scenarios and a richer user experience.

Through these features, the cross-chain bridge between DuckChain and TON not only increases asset liquidity and security but also provides users with a more open and interconnected blockchain ecosystem.
