Halle, fully known as HALLE INTERNATIONAL FOUNDATION, was established in Singapore by tech giants from Silicon Valley. The original intention of founding Halle was to create an open and business-friendly foundational public blockchain - HalleChain. To meet the fundamental requirements for large-scale commercial application deployment, the new public blockchain needs to have a fast mainnet, convenient wallet, attract high-quality miners, implement a secure consensus mechanism, and also possess significant scalability. It must be easy to develop on, aim for minimal network bandwidth, to achieve maximum openness and the highest degree of decentralization.
