Coin： Super InterPlanetary File System
SFIS is an organic combination of existing mature technologies, upgraded based on IPFS technology, which provides a distributed and efficient record of the ledger and provides comprehensive scripts to support different business logic. In a typical blockchain system, data is generated and stored in blocks, and is linked into a chain data structure in chronological order. All nodes participate in data validation, storage, and maintenance of the blockchain system. The creation of new blocks usually requires the confirmation of the majority of the whole network (the number depends on different consensus mechanisms), and broadcasts to each node to achieve network-wide synchronization, which cannot be changed or deleted afterwards. The parties here only refer to the accounting participants. The SFIS encryption system participants should be composed of multiple entities with inconsistent interests, and the accounting will be initiated by different participants in different billing cycles. Depending on the different consensus mechanisms), other participants will jointly verify the accounting information initiated by the leader.
