4.1 Model Confirmation and Training Data Privacy and Security

The js-ipfs library is used to store and transfer large model files, and only the content path hash is recorded on the chain to ensure privacy and data security. The hash chain ensures data integrity and consistency, and each file has a unique hash value, i.e., it provides tamper-proof model and data protection for AI training. The decentralized and tamper-proof characteristics provide a reliable solution and trustworthiness for model authentication, and model contributors can achieve the protection of their rights and interests in the model as an asset on the BOBchain chain without revealing their identities through zero-knowledge proof.
