This paper presented a mechanism to monitor the deletion procedure in P2P file sharing network system by using an Ethereum smart contract. To verify the IPFS synchronization status of each node, our mechanism can make sure that every node possessed the same files. For functionality evaluation, our mechanism is able to conform to GDPRs criteria. The mechanism is still a first and a work in progress. Some additional functionalities are planned to be added into this mechanism. As we have noticed, we have mentioned that our system is running under a Non-Byzantine Fault condition in Section I previously.However, to meet the ideal condition is nearly impossible.Our future work includes avoiding external untrusted nodeperforming malicious behaviors with a Trusted Platform Module.
