We design and build Lockchain, a de- centralized open source bookings ecosystem for renting hotel rooms, private properties or accom- modation (the decentralized LOC Ledger). Lock- chain will be the rst system which allows end customers and property owners to deal with each other on the platform without any fee or commis- sion. In addition to that, we will build LockChain. co - which will be the rst marketplace/applic- aiton that will connect with the decentralized engine (The LockChain.co Marketplace). The decentralized system will hold the LOC booking ledger which will be the core of the engine.
