Odaily Planet Daily News: Epic Games CEO Tim Sweeney said that the battle royale game giant "Fortnite" may use blockchain in the future, but will not adopt cryptocurrency or NFT transactions. He emphasized that the "basic concept" of blockchain has potential and may serve as a decentralized database solution. Sweeney pointed out that blockchain has failed to be fully developed in the pure technical community and has been regarded as a financial tool, which has led to problems such as speculation, fraud and regulatory uncertainty that have seriously affected its value.
