Contracts Overview

Our first smart contracts are being released with a Pool Prediction. A Pool Prediction distributes tokens between all winners according to their proportional investment in the winning outcome. The prediction winning outcome is decided by an oracle contract.

Pool Prediction

Pool Prediction Example

A prediction has 3 different outcomes:

Outcome 1
Outcome 2
Outcome 3

User A placed 100 tokens on Outcome 1
User B placed 300 tokens on Outcome 1
User C placed 100 tokens on Outcome 2
User D placed 100 tokens on Outcome 3

Total token pool: 600

For example, after the prediction ends, the oracle decides the winning outcome is Outcome 1. Users can now withdraw the following token amount from their predictions:

User A -> 150 tokens (100 / (100 + 300) * 600)
User B -> 450 tokens (300 / (100 + 300) * 600)
User C -> 0 tokens
User D -> 0 tokens

Pool Prediction Lifecycle

Initializing - The status when the prediction is first created. During this stage we define the prediction outcomes.
Published - The prediction is published and users can now predict on the different outcomes.
Resolved - The prediction is resolved and users can withdraw their winnings.
Paused - The prediction is paused and users can no longer make predictions until the prediction is published again.
Canceled - The prediction is canceled. Users can get their STX refunded to them.
