To be the Standard & Poor’s in DeFi Ecology

DeFi9 is the first prediction market project to be launched on Clover42 platform. It is a prediction game in which participants try their luck on ranking the liquidity change rate(LCR) of top 9 UniSwap tokens in the next 24 hours period.

Rules of DeFi9

We snapshot the liquidity of the 9 tokens on UniSwap at 08:00:00 GMT(end of Round T-1 and beginning of Round T) each day, and get the change rate of each token on daily basis.

The ONLY thing Players need to do would be ranking 9 tokens in order. Each prediction result would cost just 9 DAIs, 1 DAI/slot.

Players can make multiple predictions on the same order result also can make multiple predictions on different orders. Hence the total investment would always be N * 9 DAIs.

· First Prize/Ultimate Reward: Predict correctly on all 9 slots

· Second Prize: Predict correctly on any 7 slots.

· Third Prize: Predict correctly on any 5 slots.

· Fourth Prize: Predict correctly on any 3 slots.

C42 UniSwap repurchasing and Burning Mechanisms in DeFi9

There are 3 events triggering DAI distribution from DeFi9’s vault into Uniswap pool of C42 and ETH:

1. There is at least one 1st prize winner in current around.

2. Fixed number of rounds past, in any of which there is no 1st prize winner.

3. The fixed threshold on investment vault is reached.

Priorities: If more than one events happened, the priority would be event 1, event 2, event 3.

Mining Mechanism of DeFi9 Token: DF9

Prediction Mining, cannot be simpler! The system would dynamically calculate how many DF9 can be mined from a DAI at any time during prediction making. At end of each round, DF9s mined by predicting behaviors would be automatically transferred into user’s wallet.

The mining speed would be defined as algorithm in smart contract. Assuming that the investor has invested M DAI in the current round, the number of DF9 tokens mined Num is as follows:

Num=M*R, R is a function of the number of rounds T, the larger the T, the smaller the R. So early participation is encouraged.

The Concept of Becoming DeFi’s Rating Agency

Since the predictions are made on liquidity, one of the most important metric of tokens, and also because players pay for it, the aggregated predictions on each around could be interpreted as voting of trust or evaluations of future about those DeFi tokens. The Decentralized Consensus on Rating the predicting targets would be gradually formed.

As the prediction game keeps going on and on, one can use the big data of both user inputs and draw results on rating DeFi events. So the ambitions of DeFi9 and Clover42 would be the future S&P Global Rating in DeFi world.

So much for DeFi9 introduction. There are much more to expect on Algorithm Adjusted Liquidity Mining between DeFi9 and C42. Stay hungry!
