Veles Core is an open source software project aimed at helping internet users maintain information access freedom and improve communication privacy through the construction of distributed VPN and multi hop support services. VLS adopts a multi algorithm POW mechanism, which enables the network to be protected by a large number of miners with different devices. The node network will be established in two layers, with the main node providing the core functions of distributed services, and the Tier II main node being implemented as a lightweight exit node. Dynamic PoW rewards based on hash values are automatically adjusted after each halving cycle. In order to provide the most suitable environment for dVPN and other privacy protection distributed service requirements, we have constructed a customized blockchain and master node network, aiming to achieve stable, secure, and reliable network services....
