question:  How are the various local currencies connected?
context: New money: Do local currencies actually work? It might never have occurred to many of us that there are other types of exchange that can stand in for ragged bank notes tucked away in pockets, or other objects that can stand in for those notes. In India last year, desperate people burned sacks of illegal cash after the government withdrew two high-denomination notes as part of a crackdown on corruption. Timebanks, local exchange trading systems (LETS) and digital inventions like bitcoin can provide alternative ways for people to pay for goods and services when mainstream currencies hit crises. But they will only work if Britons are ready to accept that they have the power to invent their own currency. It's an idea he no longer thinks will work, because the debate, since Brexit, has shifted from the currency issue back to ideas about Scottish independence. She runs the Clacks Youth Timebank, a scheme where 12- to 15-year-olds can earn credit for volunteering. Everyone has gathered to decide what a Glasgow Pound might look like at a time when many are asking if local currencies can work at all. So they printed a currency that would have the same value as the pound, but could only be traded in independent Brixton shops, where the shopkeeper would also have to spend it locally. No two local currencies are exactly the same. But the Brixton Pound and other recent schemes follow the example ten years ago of the Totnes Pound, a 'complementary currency': that is, one supplementing the national currency. As fears for financial stability took hold during the recession, complementary currencies grew in popularity. The Bank of England does not consider these forms of currency legal tender, but the notes hold value in the same way as a gift-card from a department store, with the same kind of restrictions about where they can be spent. Proponents say complementary currencies boost spending in smaller geographical areas, which can have environmental benefits as businesses cut transport distances to deal with local suppliers. In Britain, there are now schemes in Totnes, Lewes, Brixton, Bristol and Exeter.
