Today’s demonstration at the Vietnam Blockchain show is the first time in human history that internet-free transactions between smart devices have been implemented and demonstrated. Ten years ago, Satoshi Nakamoto used the bitcoin network to achieve the first internet-based value transfers. Ten years later, all of humanity is now witnessing the direct connection of two mobile phones making SMT value transfers. Each mobile phone is equipped with Spectrum public chain second layer architecture Photon network nodes, also known as SmartRaiden. MeshBox runs Spectrum and Photon (SmartRaiden) nodes to carry out transactions under the chain, and allows mobile phones to make transactions without Internet connections. This is the unveiling of the new Spectrum blockchain 4.0 dimension. It is the M2M foundation of the distributed Internet of Things. Now, the interconnection of all things can be extended without limit, opening up a whole new era unbound from the constraints of the Internet!
