2.3.5 Proof of Zero Knowledge

BOBchain uses L2 (Layer 2 networks) and zero-knowledge proofs at the BOINC AI server.

Effectively combining a two-layer network to increase the scalability and throughput of the blockchain and reduce transaction costs and confirmation times. Combined with the advantage that zero-knowledge proofs can be used to enhance privacy and security. This allows the AI blockchain mainnet to simultaneously balance more efficient processing of learning model transactions, and privacy and security of training data.

By using zero-knowledge proofs, users can verify the validity of their transactions without disclosing their specific transaction details. This is very useful in protecting the privacy of the users as the specific transaction details are known only between the participants and are not publicly recorded on the blockchain.

At the same time, zero-knowledge proofs can be used to enhance the security of BOINC AI Server L2 network nodes. By using zero-knowledge proofs, participants can prove that they own certain assets or fulfil specific conditions without having to disclose specific asset or condition information. This prevents malicious actors from accessing sensitive information or using information leakage for attacks.

In particular, in our PoVC arithmetic value consensus mechanism, for AI model training, the training data will not be recorded on the chain. The node responsible for training only needs to generate a proof using a specific key to prove to the training task publisher that "the training task is complete", and submit this zero-knowledge proof on the chain for verification by the task publisher. In this process, the model itself is not directly disclosed, nor is the data content used for training disclosed.

Therefore, the use of "Zero Knowledge Proof" for the L2 network nodes of BOINC AI server can provide better privacy protection and security while maintaining the transparency and verifiability of the blockchain. This provides users with a better user experience and higher security, and also promotes the further development and application of the combination of blockchain technology and AI technology.
