In the main conference \u2018D. FINE\u2019 of Asia\u2019s biggest blockchain festival Korea Blockchain Week (KBW 2019), the application of blockchain in the gaming industry was discussed. Many blockchain and gaming proponents stressed on the fact that \u201ckiller applications\u201d could be created using blockchain technology.\r\n\r\nGamers have an instinct that blockchain technology can be used for in-game purchases or item trading using digital assets. Therefore, many experts are optimistic that online gaming is the sector where the first service using blockchain technology can materialize. The analysis also suggests that blockchain-based games will become very familiar among the general public.\r\n\r\nExperts who attended KBW 2019 believe that \u201cBlockchain will create a new in-game economic system.\u201d\r\n\r\nChoi Sung-won, Head of Strategy and P2P Network Expert, who once held the first position in blockchain games, said that \u201cWe are preparing e-sports services where users can trust each other and compete.\u201d They are working on combining blockchain technology with gaming seamlessly, where players could \u201cTake the ownership of items to users with blockchain.\u201d\r\n\r\nBesides, Choi said,\r\nYou can connect any one game to another game. For example, you could open treasure boxes in CryptoDozer with keys obtained elsewhere or vice-versa.\r\nKoh Kwang-Wook, general manager of PlayDapp Technology, said,\r\nBlockchain technology can give users ownership of items and help to implement a system that can use to trust and trade items on the blockchain system.\r\nPlayDapp is a blockchain-based game service platform. They offer dApp (Decentralized Application) games that are developed on the blockchain public database system and facilitate the utilization of free items and trading between games. Their in-system token, PLA, is used for transactions between users. PlayDapp operators or developers earn PLA for each purchase or trading that takes place in-game, after deduction of a nominal fee by PlayDapp.
