They have built two networks on blockchain that solve problems of the everyday economy.
The first one is MonedaPar.com, which allows 800 micro-SMEs in many different Argentinian cities to sell more and access to credit. On the other hand, Discoin was launched a year after MonedaPar. It is a network which encourages citizens to shop local at 40 shops in La Plata, Argentina. Thanks to Discoin, local businesses can use their idle capacity, while keeping the wealth within the city.
