Local currencies are powerful tools to encourage consumers to buy products developed in the area. Buying local helps communities strengthen their economies, become more resilient and increase the purchasing power of their members. When properly designed and implemented, local currencies contribute to economic growth and development. As a result, both local businesses and citizens benefit from higher levels of activity that are more sustainable.

A Mutual Credit Hub is a credit system developed between two parts of a given community (freelancers, SMEs, cooperatives). The only requirement to gain access to this economic hub is to demonstrate the ability to pay back to the community the same amount that is being borrowed in the first place. All loans are provided at a zero rate of interest, since the currency used for these transactions is the same cryptocurrency that has been generated by the community. In a mutual credit system we are all prosumers - all of us need to consume from the community's production, but at the same time we all have something to give to our fellow community members. In a mutual credit system we can also decide to give value to certain activities that the market usually doesn't remunerate

The aim of this hub is to take advantage of the valuable resources that society discards, in order to transform them into useful products and a source of income for the community members. This can be achieved with a token that rewards those who recycle. Collaborators are paid with a token that indicates the amount of waste (in kilos) that they have contributed. The recycling center can use the waste provided for the production, or sale, of "green inputs" to industries. The token generated is used to purchase products from local businesses, or to pay local taxes. Local businesses can also pay a part of their taxes in tokens, as well as purchase products from other businesses. The government is compensated by the expenses savings in legal tender, implying reduced waste management outside the circular economy paradigm. In this economic cycle waste, community products and tokens are combined to align the behavior of the different actors in a way that it becomes beneficial for the environment, the local economy and the common good.

This hub generates an intelligent electric network in which energy generation from renewable sources is rewarded with the complementary currency developed for that purpose, The participants can buy and sell solar energy to each others. Some households can generate their own energy with photovoltaic panels - if they produce more than what they actually need, they can offer the surplus into the network and get as many tokens as KW delivered.

These tokens work as a complementary currency within the community: goods and services can be purchased from local businesses, as well as other households unable to generate energy. The renewable energy zone is not only beneficial to environmental care: it can also stimulate the local economy. It contributes to the creation of a city that is more autonomous, taking into account the advantages of smart grids for the power cutoff management and the reliability of the electrical system.

The Commercial Credit Hub is a credit system within a business network. Each company adhering to the system can buy products by issuing tokens, that have a fixed 1 to 1 parity with the legal currency. This transaction works like a zero-interest rate credit: the company that issued tokens to buy products must pay the system administration, within a set period of time, the amount of legal tender corresponding to the number of tokens it had issued. Each token is associated with a specific credit and a specific expiration date. Let's take the example of a business that doesn't have sufficient liquidity to buy 5,000 legal tender worth of goods produced by another company in the network. Instead of going for the traditional banking system credit, this company can offer 5,000 tokens that will expire in 90 days, in exchange for the goods.

These tokens work as an internal means of payment: they can be exchanged for other products within the rest of the companies in the network. When the expiration deadline is reached, the company that has issued tokens must pay the administration 5,000 legal tender to pay off its debt. Then, the companies owning the issued tokens can swap these with the administration, in exchange for the corresponding legal tender. In that way, companies can successfully have access to short-term credit at a zero interest rate.

The goal of this system is to promote good fiscal behavior and encouraging people to participate in activities that contribute to the common good. These behaviors can be rewarded through a complementary currency that people can use to pay municipal taxes, or to get discounts from local businesses. Since the token is accepted only within the limits of the town wealth does not leak from the local economy. The government controls the issuance and distribution of the currency, as well as the parameters that define the operations within the system.

In this Hub, the members of a given community provide services in exchange for tokens that represent working hours. All the working hours have the same value: one hour of cooking class is equal to one hour of childcare.

In this system, the account unit is the working hour: the participants can access to a loan to obtain the services of another participant, as long as they agree to offer hours of their own work to pay off their debt. The number of hours acquired must equal the amount provided to the community, Alternatively, a community member may go into debt to take guitar lessons, with the commitment to offer his services later.
