Demurrage
The thinking behind demurrage is that since most goods depreciate in value, the money we use to represent them, should depreciate as well. This will encourage us to use the currency as a medium of exchange rather than as a store of value, hence encouraging us to invest in real life improvements.
On the first day of each month, everyone's accounts will be charged 2% in interest depending on how far away from the original 250 samaras you are. For example if you had 120 samaras, on the first of the month, this will decrease to 117 samaras. This diagram shows exactly how much you will be charged depending on your balance.
This interest charge should encourage circulation of samaras and discourage hoarding or large debts. It makes it in your interests to keep your balance as close to 250 as possible, whether above or below it. The only way to do that is to trade all the time (or not at all). The 2% interest is thought to be small enough not to discourage trading. It is really only a token charge, meant to create an incentive to trade in samaras.
This form of interest is called demurrage and has been extremely successful in local currencies in Germany and Austria during the Great Depression; in national currencies in Europe during the Middle Ages when all the cathedrals were built; and even in Ancient Egypt when the pyramids were built.

Where Does the Demurrage Charge Go?
50% of the interest will be directed to a special communal account. As the samaras accumulate, neighbours will be able to apply to spend them for social or environmental projects in their local area. You could use it to pay people to replant the nature strips with fruit trees, to doorknock to get more people involved, to cook and deliver meals to the elderly, or whatever you think you need most in your area.
The other 50% of the interest will be redirected to the admin account of the Sharehood. Since the Sharehood runs on limited funding, these samaras will be used to compensate people who work on the project. Whether that be promoting the Sharehood, running workshops, writing articles, working on the website, or networking the Sharehood with other community groups. If you are interested in taking on any of this work, please let us know (at the moment its all just volunteering though).
However, keep in mind that if the incentive is working correctly, there will not be much currency collected through this system.
