How Discoin automatically adjusts for inflation.

Dynamic rates and reserve

Setup

Discoin starts with a currency called ABC with a reserve of 100.

{% hint style="info" %} You can think of the reserve as a big bank vault where Discoin goes to get the coins when someone is exchanging currencies. {% endhint %}

Each ABC is equivalent to 2 Discoin tokens (𝔻$), and vice versa.

That means the market cap of ABC is 200𝔻$.

$$ 100 \space \text{ABC} \times \frac{2\mathbb{D}$}{1 \space \text{ABC}} = 200\mathbb{D}$ $$

A transaction is started

A user wants to convert 10 ABC into XYZ.

Discoin has their 10 ABC added to the reserve.

$$ 100 \space \text{ABC} + 10 \space \text{ABC} $$

The Discoin reserve is now holding 110 ABC.

The market cap of all the ABC in 𝔻$ should still be 200𝔻$.

To keep the market cap at the same value we devalue ABC.

$$ \frac{200\mathbb{D}$}{110 \space \text{ABC}} = \frac{1.81\mathbb{D}$}{1 \space \text{ABC}} $$

The new value of 1 ABC is now 1.81𝔻$.

The response from the API directs the receiving bot to payout the correct amount of XYZ. This value is derived by converting the currencies like this:

$$ 10 \space \text{ABC} \rightarrow 18.1 \space \mathbb{D}$ \rightarrow\text{XYZ} $$

Connecting to the reality, Discoin uses a mix of Bretton Woods System (pegging against a certain amount of resource, in their case Gold, in our case Discoin tokens) and floating exchange rate (supply and demand flunctuates the rate).
