NBS is the OSS (open source) solution of DFI (decentralized Finance) business and DEX (decentralized exchange) based on dpos consensus and realized by Dao's organizational management architecture, which was first jointly born by EOS founder Daniel Larimar, Ethereum and Cardano (ADA) founder Charles hoskinson. The graphene technology used by NBS is one of the most advanced blockchain technologies in the market. Since its launch on September 10, 2020, NBS has been adhering to the concept of "using Delphi for win-win, reconstructing the economic ecology of the public chain, using free sharing to realize the inclusive application of Delphi", revolutionized the application of stable currency, realized the gold standard and currency standard mining and the sustainable contract function on the DEX internal disk, and added cross chain (NBS connect) on the basis of the original graphene architecture, Oracle (NBS forcast), virtual machine EVM and NFT non homogenization pass function. Reconstruct the economic model of the public chain through defi to form a real closed loop of NBS ecology. At the same time, as an efficient blockchain DEX infrastructure, NBS significantly reduces the capital threshold and cost for users to participate in transactions. NFT function can be applied to digital collections, game items, digital commodities, event tickets, real estate, identity documents, certificates and other fields.
