Stable cost: Giving nonprofits enough to buy 1 CPI basket always gets you 300 GC.
Printable green NFT-based cryptocurrency you get by giving money to charity
For every donation equivalent to a CPI basket that you give away to nonprofit charities, you get 300 GC in face value.
A CPI basket is a fixed amount of stuff, the cost of which in U.S. dollars naturally changes due to inflation and deflation. The current cost is published at economy.com.
Whatever the current cost of a CPI basket in U.S. dollars, when you give that much as a gift split among 5 nonprofits, you get 300 GC.
(You can give any fraction of a basket, too).
GC face values represent a true and honest opportunity cost in buying power: 1 GC always costs 1/300th the cost of that fixed basket of stuff.
CPI baskets currently cost $288 in USD, so 1 GC currently costs about 1 USD.
Denominations and Special Editions
GlobalChange comes in ones, fives, tens, twenties, and so on, like U.S. dollars. If you mint 10 GC, you can get one ten, two fives, ten ones - whatever you choose. You can also make change, if you later decide you want smaller denominations.
Each denomination has a personality. Instead of George Washington, Queen Elizabeth, kings, and emperors, we get Billy, Fi-Yive, Decker, and more.
GC bills can be generic, like the ones on the right. Each generic bill lists the nonprofits that received funding allowing the bill to be minted.
Or, depending on luck, you might get a Special Edition piece of digital art attached to your bill, essentially a nested NFT.
Special Edition art is crowdsourced from artists, and has varying levels of scarcity. Art can be jpegs, gifs, moving gifs, audio files - any file or any NFT, really. The Whitepaper explains how non-image art can be represented on bills.
Artists who provide art can specify particular nonprofits, so the only way to get a certain artist's art on your bills might be to give money to the nonprofit the artist is supporting.
Below, you can see a a Special Edition GlobalChange bill that includes a piece of art that is allowed to go onto bills after someone's donation to a set of nonprofits includes Crypto for the Homeless, an organization that turns cryptocurrency donations into food for people who are currently homeless. You can confirm that this nonprofit indeed received the appropriate gift by searching for the bill's serial number on the blockchain, as described in the Whitepaper. (The reason why gifts go to a group of 5 nonprofits is also explained in the Whitepaper).
GlobalChange can work across multiple blockchains, or support its own. Stellar Lumens is a great place to start. Stellar includes all functionality necessary to support GlobalChange digital money, and has very low transaction fees - by design, transactions are almost free.
Stellar is supported by a nonprofit organization itself, Stellar Development Foundation:"The future of blockchain adoption must be inclusive and affordable across global markets. Stellar promotes financial access anywhere there is unmet need or untapped potential."
You can bundle together bills and also coins to make payments, quickly and globally.
If you want, you can make change, breaking a larger denomination into smaller bills or coins.
Transactions take seconds, and each transaction is virtually free, costing a fraction of a cent on the Stellar Lumens blockchain. Transaction costs are less than rounding error, even for small micropayments.
So you can pay your friend back for a cup of coffee by sending them a bundle of NFTs with face values.
