Share (シャレ(洒落),シェア) is the name for aclosed-sourceP2P 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 toWinny. Like Winny,Share functions using adistributed data store referred to as acache with each computer acting as anode in the network. Netagent published a survey in June 2018 suggesting that Share was the third most popular p2p network in Japan afterWinny andPerfect Dark (P2P) with approximately 10,000 nodes connecting each day over Golden Week, down from 30,000 in 2015.[1]
Share's logo refers to theLaughing Man, which is a fictional character from the anime seriesGhost in the Shell: Stand Alone Complex, as an anonymous hacker.
Share usesencryption 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 aplugin system. The plugins andPDK are readily available through theShare network. The PDK is written inDelphi.
UnlikeWinny,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.
LikeWinny,Share uses « Trip IDs » to verify the identity of a person sharing a file. A « Trip ID » is a sort of encrypted key that identifies a person who they say they are. This allows users to decide whether or not they trust a person based on their previous sharing experience with them.
When a new version ofShare becomes available, users are given a notice in theShare statusbar. When this happens, users can search for the new version on theShare network, and download it from a reliable source based on Trip.
Share is highly popular in Japan, but in the West, some concerns have been raised.
Share can be downloaded from theShare P2P andP2P ファイル共有ソフトノード登録所 websites.
UnlikeWinny,Share includes an option forlanguage localisation changes (labeling of buttons, etc.). The locale.txt file contains the information for a particular language and resides in theShare directory.
