The Hidden Lake is an anonymous network built on a micro-service architecture. At the heart of HL is the core - HLS (service), which generates anonymizing traffic and combines many other services (for example, HLF and HLM). Thus, Hidden Lake is not a whole and monolithic solution, but a composition of several combined services. The HL is a friend-to-friend (F2F) network, which means building trusted communications. Due to this approach, members of the HL network can avoid spam in their direction, as well as possible attacks if vulnerabilities are found in the code. List of applications: * Basic: - HLS :: anonymizes traffic using the QB-problem - HLC :: runs many HL services as one application - HLA :: adapts HL traffic to external environments * Applied: - HLM :: messenger with a web interface - HLF :: file sharing with a web interface - HLR :: executes remote access commands - HLP :: ping the node to check the online status
