Blizzard Entertainment Co., Ltd., Blizzard game platform, began in 1997 Blizzard to cooperate with the release of "Diablo" development of the game platform, in China at first for Battle.net, in 2016 Blizzard official website said that it was renamed Blizzard game platform

Battle.net is a game battle platform built by Blizzard. Battle.net is a direct way to connect to the Internet, allowing players from all over the world to venture out and travel with each other. Game platforms such as HF and VS can be used to play online with people online. Battle.net plays the role of connecting various gamers and providing a competitive platform. It has played an indispensable role in the promotion of major competitive games.

In 1997, in order to coincide with the release of "Diablo", Blizzard began to set up a Battle.net game platform (commonly known as Blizzard Battle.net), the initial Battle.net was only for "Diablo" players, allowing WAN players to enter LAN games, in addition, no player data or data is stored on Blizzard servers, players are basically in a state of direct connection to each other, which also makes cheating commonplace. In 1998, Blizzard released StarCraft and introduced new protections or restrictions on Battle.net players, requiring the use of StarCraft's 13-bit valid CDkey to access Battle.net, as well as advanced systems such as chat and ranking.

Diablo 2, released in 2000, made Battle.net a true server-client model, with player data stored on Blizzard servers, which made it more effective to eliminate cheats such as modifying game data.

In terms of competitive games interstellar and Warcraft, the Battle.net Ladder ranking system immerses all players who are interested in honing their skills in the game of victory and defeat, the Ladder system randomly matches your opponent, and the level of the opponent matched is also similar to yours, because the player cannot specify the opponent, which effectively eliminates the possibility of scoring on both sides, and also prevents players with too large a level gap from meeting early. At present, Battle.net is mainly divided into four regions: Asia (mainly South Korea), US East, US West and Europe, and in 2010, Battle.net joined China.

In September 2016, Blizzard's official website stated that we will no longer use the name of Battle.net for the game services and related functions we provide, but will change its name to "Blizzard tech". Blizzard's online service will have a brand new name – the Blizzard Gaming Platform.
