DOL Security

In the DuckChain architecture, the security of the Decentralized Oracle Layer (DOL) is key to the stable and reliable operation of the entire system. Through its unique design and mechanisms, the DOL ensures data accuracy, system transparency, and overall security.

First, the DOL adopts a decentralized architecture. This design means the network does not rely on a single entity, significantly reducing the risk of single points of failure. Multiple Oracle nodes are distributed across the network, working together to provide data and verify states, enhancing the system's resistance to censorship and attacks. This decentralized model not only increases system resilience but also makes it more difficult for any attempt to tamper with data.

Second, the data verification mechanism of the DOL is at the core of its security. Oracle nodes are responsible not only for collecting data but also for verifying its accuracy and reliability. Multiple verification mechanisms ensure the data provided to DuckChain is accurate and error-free. Additionally, encryption technology and digital signatures are used to verify the source and integrity of the data, further preventing tampering during transmission. This rigorous data verification process provides a solid data foundation for DuckChain.

The DOL is also responsible for publishing the state root of DuckChain to the TON blockchain. The state root is a hash value of DuckChain's global state, representing the complete state at a specific moment. By publishing the state root to the TON blockchain, participants across the network can verify and confirm the state of DuckChain, greatly enhancing system transparency and credibility. The state root publishing mechanism is not only periodic but also ensures that participants on the TON blockchain can verify DuckChain's state in real-time, providing a reliable verification mechanism for the entire system.

Lastly, the multisignature mechanism plays a critical role in the DOL. In key operations, the multisignature mechanism ensures consensus among multiple proposers and reviewers nodes. This increases the security of operations and prevents malicious behavior from a single node. The multisignature mechanism requires signatures from multiple authorized nodes to execute operations, thus enhancing system security and ensuring the irreversibility and consistency of key operations. Through these measures, the DOL not only ensures data accuracy and system transparency from a technical perspective but also enhances the overall security and reliability of the system in practical operations. This comprehensive security strategy enables DuckChain to provide users with a secure, reliable, and efficient blockchain service.

DAVL Message Verification and Security

In the DuckChain architecture, cross-chain message verification and security are critical to ensuring the correct transfer of assets and the overall stability of the system. Below is an optimized description of the cross-chain message verification and security mechanisms:

Message Verification Mechanism

In the DuckChain system, users may attempt to send cross-chain messages claiming that assets have been transferred to a smart contract (such as TON.CrossChainMessage) without actually transferring the corresponding assets. To address this, the system employs a stringent verification process:

• Decentralized Proposal and Review Model: During the cross-chain message transmission process, staked assets can be proposed for transfer by Proposers. Multiple independent Reviewers will jointly verify the authenticity of these proposals. This design ensures a decentralized review process, avoiding reliance on a single entity.

• Consensus Security Framework: In cross-chain messages, Proposers and Reviewers follow a consensus security framework to verify the declared asset amount against the actual transferred asset amount. This process includes comparing historical transaction records and confirming asset sources and destinations to ensure information accuracy and prevent potential errors or asset misuse due to information mismatches.

• Dynamic Asset Management and Risk Control Framework: The system design includes strict dynamic asset management and risk control frameworks. If the asset amount in the message does not match the actual transferred asset amount, the target address will not be able to spend more than the actual transferred assets. This mechanism provides additional protection for asset accuracy and security.

Message Security

To further enhance the security of cross-chain messages, Reviewers play a crucial role in the message verification process:

• Voting Mechanism: Reviewers vote on cross-chain messages. Cross-chain messages are only confirmed and allowed to pass if enough votes reach a preset threshold. This voting mechanism increases the system's resistance to attacks and ensures the security and reliability of cross-chain operations.

• Threshold Setting: By setting reasonable voting thresholds, the system can prevent a small number of malicious nodes from affecting cross-chain operations. This design not only improves system security but also enhances the transparency and fairness of cross-chain operations.

Through these measures, the DuckChain system not only ensures the accuracy of cross-chain messages and the security of assets, but also enhances the stability and trustworthiness of the entire blockchain network. This comprehensive verification and security mechanism provides users and developers with a secure, reliable, and efficient cross-chain operation environment.
