Active Validation Service
The Active Validation Service (AVS) is a core feature within the Bracle Network, designed to ensure the accuracy and reliability of data across the network. It enhances data security and provides a more reliable data source for decentralized applications (DApps) and smart contracts by actively validating data services using the security and liquidity of Bitcoin. Bracle Network has partnered with BabylonChain to jointly develop a higher-quality Active Validation Service (AVS). AVS aims to address the trust issues associated with traditional centralized oracles and the challenges of validation efficiency and cost faced by other decentralized oracles. It seeks to improve the overall performance and reliability of the Bracle Network through:
Enhancing the decentralization of data validation: Utilizing the collective verification of network participants to ensure the authenticity and accuracy of data sources.
Increasing efficiency and reducing the cost of data processing: Optimizing the verification process through smart contracts and specific validation algorithms to reduce unnecessary computational and transaction costs.
Boosting network security: Increasing potential attackers' cost of attacks and enhancing the network's overall security level by actively validating data services using Bitcoin's security and liquidity.
Operating Mechanism
AVS operates through the following key steps:
Data Submission: Data providers must sign their data before submitting it to the Bracle Network, proving the authenticity of its source.
Validation Request: Upon data submission, AVS automatically triggers a validation request, inviting verification nodes in the network to participate in the data validation process.
Random Selection of Verification Nodes: To prevent potential collusion and ensure the fairness of the validation process, AVS uses an algorithm to randomly select a certain number of verification nodes for each verification.
Execution of Verification: The selected verification nodes validate the data according to predefined rules and algorithms, including cross-verifying data sources, checking the validity of data signatures, and comparing them with known, trusted data sources.
Result Aggregation: All participating nodes submit their verification results to a smart contract, which aggregates the results according to certain logic (e.g., majority voting) to decide whether the network accepts the data.
Rewards and Penalties: Nodes that successfully participate in the verification and whose votes are consistent with the final outcome receive token rewards. Nodes that submit incorrect data or validations may face penalties, including the loss of staked tokens.
Features of AVS
Decentralization and Autonomy: AVS's design allows the network to autonomously complete the data validation process in a decentralized manner, without relying on any centralized third party.
Flexibility and Scalability: With smart contracts and a dynamically adjustable verification mechanism, AVS can flexibly meet various types of data validation needs and scale as the network grows.
Transparency and Fairness: The validation process and results are recorded on the blockchain, available for review by all network participants, ensuring process transparency and result fairness.
By implementing AVS, the Bracle Network aims to build a more secure, reliable, and decentralized data validation and oracle service, providing robust data support for applications within the blockchain ecosystem.
