Share (P2P)

is the name for a closed-source application being developed in Japan by ファイル倉庫, a pseudonym translating as 'file warehouse.' Share was developed to be the successor to Winny. Like Winny, Share functions using a distributed data store referred to as a cache with each computer acting as a node in the network. Netagent published a survey in June 2018 suggesting that Share was the third most popular p2p network in Japan after Winny and Perfect Dark (P2P) with approximately 10,000 nodes connecting each day over Golden Week, down from 30,000 in 2015. Share's logo refers to the Laughing Man, which is a fictional character from the anime series Ghost in the Shell: Stand Alone Complex, as an anonymous hacker. Share uses encryption to hide the identity of who is transferring or what they are transferring. It is non-centralized so it cannot be easily shut down and it supports multiple source "swarm" downloading. All files are transferred encrypted so they must be decrypted upon download completion. In the meantime they are stored in encrypted form in a "Cache" folder. This folder is also used to allow recently downloaded files to be shared among the network based on priorities. Share also features a plugin system. The plugins and PDK are readily available through the Share network. The PDK is written in Delphi. Unlike Winny, Share allows users to specify up to 255 Cluster Keywords, though only 5 can be active at once (Winny only allowed 3 cluster words, and its system was more confusing). These are used to connect to nodes that have also specified the same Cluster Keywords. This allows users to maintain connections with nodes that are sharing files they might be interested in, while disconnecting from nodes that share content they are not concerned about. Users can specify auto-download triggers and auto-block filters. The network also appears to have some sort of a "forgery warning" system to warn people about possible falsified data/files. Like Winny, Share uses « Trip IDs » to verify the identity of a person sharing a file.
