Game 1: Guru vs Guru

Guru vs Guru is the first non-custodial smart contract price prediction game developed for BCH Guru. It consists of two players, both predicting prices for a crypto asset on a certain date and time.

Player 1 initiates the game by creating a new on-chain price prediction, choosing asset, time of prediction and their stake. Player 1's price call itself remains secret, whereas the rest of the prediction details are published for any player wishing to accept the game offer, by providing a price call of their own and a matching stake. Once Player 2 joins, the game is public and both player's price calls are visible to watch. The player with the closest price prediction at the time of prediction time receives the payout.

Creating an Offer

Player 1 initially creates a crypto price prediction offer. This is done by selecting a number of parameters:

• Asset to predict
• Time and date of prediction
• Price prediction (in USD)
• Asset to stake (to back your call)
• Amount of selected asset to stake
• Offer expiry

There will initially be some parameter limits during BCH Guru Beta. Beta launches with three assets to choose from (BCH / BTC / ETH) and predictions must be at least 12 hours in advance, with a 45 day limit on future predictions.

Furthermore, in the Beta period, only FURU tokens can be staked, with a maximum limit of 100,000 FURU tokens per stake.

Offer Expiry

Offer expiry is the window in which Player 1 wishes to keep their offer open to other players. After the offer expires, the offer will no longer be available for players to accept, and will enter an expiring phase, before auto-returning the funds to Player 1's wallet.

Cancelling an Offer

Once an offer has been made, Player 1 can withdraw the offer by cancelling it and the stake funds are returned to the wallet. This will only be available whilst the offer is open. If Player 2 accepts the offer, the game begins and Player 1 can no longer cancel the offer.

Accepting an Offer

If an offer is open, it will be visible to all users on the application. All details of the offer will be available to reivew, except Player 1's price call, which will remain secret. Player 2 can accept the offer by making a matching price prediction and matching the stake. Once a game has started, both Players' price calls become public.

Determining the winner

The winner is determined by the oracles published for the asset being played. The oracle message used to determine the winner is the first oracle message after the prediction time. The closest price prediction to this message will receive the payout, and the losing player will receive nothing. In the event of a draw, the payout will split equally between both players.

Recovery Clause

In the event that either the price oracles and / or the settlement service has a permanent disruption, funds within the contract still have a recovery clause. If the contract remains unsettled 5 days after the prediction time, funds can be claimed back by the players. This will return the stakes equally to the participating wallets.

Note: Tooling for this recovery is in development but not completed currently.

Understanding Fees

Interacting with the Bitcoin Cash blockchain requires network fees. When an offer is created, accepted, cancelled or paid out, BCH network fees are required. Although network fees are extremely small, these are not accounted for in the following fee descriptions:

FURU gameplay

There are no Guru fees, Oracle fees, or any dividends paid out for FURU play. 100% of the stake payout is distributed to the winning price prediction (excluding network fees).

What are FURU Tokens?

The FURU Token is a fungible CashToken on Bitcoin Cash mainchain and exclusively integrated into the BCH Guru application. FURU tokens can be used to stake price predictions on-chain and is the only CashToken that can be used to stake. Bitcoin Cash (BCH) is the only other asset that is stakeable on BCH Guru.

The official FURU Token ID is: d9ab24ed15a7846cc3d9e004aa5cb976860f13dac1ead05784ee4f4622af96ea

Tokenomics

FURU Tokens are distributed freely, with no initial value, solely to BCH Guru NFT holders over two airdrops. More details about the tokenomics, airdrops, and collection multipliers can be found here: Furunomics.

Obtaining FURU Tokens

FURU tokens can also be obtained on decentralized exchanges (DEXs). DEXs are third parties within the CashToken ecosystem and therefore it recommended to do your own research when interacting with them. The following DEXs are currently available for CashTokens:

• Cauldron.quest
• TapSwap.cash
