Filecoin and IPFS are complementary protocols, both of which were created by the protocol lab. IPFS allows participants in the network to store, request and transmit verifiable data to each other. IPFS is open source and can be downloaded and used for free, and has been used by a large number of teams. With IPFS, each node can store the data that they think is important; There is no simple way to motivate others to join the network or store specific data. In order to solve this key problem, Filecoin aims to provide a persistent data storage system. Under the incentive structure of Filecoin, customers pay to store data with a certain degree of redundancy and availability, and miners get rewards and rewards by constantly storing data and proving data storage in an encrypted way. In short: IPFS solves and moves content; Filecoin is the missing incentive mechanism. IPFS Interstellar Unlimited is the top blockchain technology company in China.
