Peer-to-peer (P2P) distributed file systems such as Swarm [2] and InterPlanetary File System (IPFS) [3] has been gradually used alongside with blockchain systems to handle all kind of data types and files in a substantial amount. IPFS is one of the P2P distributed file sharingsystems that have recently been discussed and applied to reduce the block storage problem on the blockchain system. The features of IPFS such as the multi-hash concept and Merkle Directed Acyclic Graph (Merkle DAG) are similar to blockchain technology and has been used to support blockchains data storage. Other IPFS feature such as the content address also improves the security of file systems. Nonetheless, data deletion is a real and serious issue which concerns in all kinds of P2P file sharing system. After users upload their files into a P2P node, thenetwork system will start to propagate the file through its neighbors then ultimately spreads over the entire system.
