"In his book The Future of Money, Lietaer points out - as the government did yesterday - that in situations like ours everything grinds to a halt for want of money. But he also explains that there is no reason why this money should take the form of sterling or be issued by the banks. Money consists only of "an agreement within a community to use something as a medium of exchange." The medium of exchange could be anything, as long as everyone who uses it trusts that everyone else will recognize its value. During the Great Depression, businesses in the United States issued rabbit tails, seashells and wooden discs as currency, as well as all manner of papers and metal tokens. In 1971, Jaime Lerner, the mayor of Curitiba in Brazil, kick-started the economy of the city and solved two major social problems by issuing currency in the form of bus tokens. People earned them by picking and sorting litter: thus cleaning the streets and acquiring the means to commute to work. Schemes like this helped Curitiba become one of the most prosperous cities in Brazil."

“Dr. Bernard Lietaer, Co-creator of the Euro and a pioneer in community currencies, joined the Bancor Protocol Foundation last year and will advise the project. Both he and the Bancor team have been outspoken on the potential of community currencies to combat global poverty using a bottom-up approach to sustainable economic development. The efforts come as a number of groups aim to use blockchain and smart contracts to build the next generation of aid and impact investing tools.”

“People concerned with sustainability in general – with issues like climate change, environmental degradation, food and water shortages, population growth and energy use – tend not to worry about the money system. Nor do they tend to look for solutions that involve monetary innovations. Even those economists who are also concerned about sustainability in principle are seldom aware that our money system systematically encourages unsustainable behaviour patterns that may end up threatening human survival on this planet.”

“Dealing with the Eurozone Crisis... Another Way? As we go to press, the Greek electorate – after two years of drastic austerity measures – has voted clearly against the cuts, the bailout and the political mainstream. Chaos in the eurozone seems one step closer. So we take this opportunity to outline how just one of the proposals from this book can be applied now, in Greece, Spain or any other country facing this kind of crisis. It’s a solution that mainstream financiers and media avoid discussing, but it’s elegant and simple. It would work, and the necessary software is available now. Current monetary orthodoxy says that 100% of the Greek economy must be either ‘in’ or ‘out’ of the eurozone. Everybody knows that either option will entail even higher unemployment and yet more misery. But it doesn’t have to be that way! The core principle of complementary currencies, as set out here, is that they run alongside the main currency, increasing resilience and flexibility for the entire socio-economic system.”

“However, is this what best serves our world today? I submit that those aspects of our monetary system that met the objectives of another time and age are now inadequate for the challenges facing us during an Information Age. This is particularly true in light of the fact that working solutions are already underway, with thousands of communities around the world taking their own money initiatives. They are creating new wealth, while solving social problems without taxation or regulation. They are empowering self-organising communities, while increasing overall economic and social stability. Finally, they enable the creation of very necessary social capital without attaching the established capital formation process.”

“We allocate a great portion of our physical, emotional, and mental energy to getting, keeping, and spending money - but how many of us really know what money is or where it comes from? Money is created when banks lend it into existence.”

“Here’s our systemic solution in a nutshell:”
