The QBC Cube public blockchain was formed and developed by the Singapore Shell Investment Fund in July 2019. The team of 14 IT members all have years of extensive experience in cryptography, blockchain technology, internet services, and financial investments. QBC was officially launched in July 2020 and received support from various blockchain enthusiasts communities such as M Community, Gold Medal Community, Xin Senyuan Community, Tamarisk Community, and Northeast Tiger Community. The management team leverages QBCs public chain technology combined with traditional financial attributes to create a decentralized finance (DeFi) mining pool, pioneering a new model of decentralized community coin mining. The QBC commercial plan covers numerous areas including a decentralized marketplace, business payments, gaming, communications, and blockchain integration for small and medium-sized enterprises, which are being rolled out according to project progress.
