A new blockchain-based application, dedicated to the purchase, sale and financing of residential and commercial real estate. The openness of the blockchain leads to more transparency, trust and also to lower costs. We want to offer an application that makes the real estate market clearer and, above all, cheaper. An application that makes it easier, for example, to obtain financing for a home. So that when purchasing a house or a commercial property, it is no longer necessary to make use of the traditional parties as we know today. In order to maintain our blockchain, we have introduced the crypto currency MarbCoin. The new crypto currency MarbCoin with support for smart contracts is now available for purchase at a reduced rate.
