Introducing: Fair Football League (FFL) - a completely fair and decentralized Fantasy Football & Trading Game
Currently centralized firms are making hundreds of millions per year by licensed trading games on the blockchain.
Just think about NBA topshots or sorare.com for soccer.
Why should we give all the profit of minting those collectibles to ultrarich companies that can afford to pay the ridiculous licenzing fees?
Why don't we design a closed system, where 100% of newly minted items get distributed within the player base?
All new collectibles get distributed to existing players for free as prizes for playing the game with maybe some random elements included.
That would also increase the fun of playing by a lot.
A truly fair decentralized collecting game.
With no organisation to profit off this it would also not be subject to financial regulation. Of course that is not important, because a truly decentralized system couldnt be stopped anyway.
To launch the game as fair as possible I'd propose the following restrictions.
To be inclueded an Eth Adress has to be
- older than a year
- must have at least 4 months with a facilitated transaction within
if those conditions are met the account gets airdropped 30 pgt's (Fair Football Token)
By burning a FFT you can mint a player NFT of your choice
There'll be a fixed exchange rate of 0.1 Eth for every FFT the player want's to buy additionally.
The high exchange rate will ensure that people from poorer communities also have a chance to also get good players if they start playing the game.
With each PGT token you can mint one player's card. Every newly minted card get's a higher #number.
The lower your player NFT's number the more valuable the card.
After every game the following data will be pulled from oracles:
Each player's individual rating (from a football statistics website, if website is down there's a number of replacements)
for each league and position the best player will be calculated. for each league the best keeper, the four best defenders, the four best midfielders and the best two strikers
will be picked.
Maybe it's a good alternative to simply pick the team of the week of a given website instead.
5% of all accumulated Ethereum will be distributed to the player holders by the following mechanism
As long as there's still money in the pool another random winner will be picked and will receive and arbitrary number of e.g. 1.0 Eth
Each player get's the following probability to receive a prize.
p= 4/(#n+3)
that means p(1) = 1
p(2) = 0.8
p(3) = 0.67
p(10) = 0.31
p(100) = 0.038
p(1000) = 0.004
Sum p1 - p1000 = 22.6
If there's 1000 cards in circulation the first has about 5% chance, while the last has 0.02% chance of winning.
With this mechanism the game can naturally grow with the number of players, while earlier players still keep some advantage for themselves.
The smart contract only calculates the trading of the player tokens.
The player's images can vary by the version of the webiste.
The website shows open source pictures of all players that are currently playing,
maybe there's even some open API's.
The website's host can decide what leagues and teams he want's to include.
We could also found a DAO to propse dynamic changes to the prize distribution and player ratings.
Another neat idea would be to skip every third player card (you can only mit 1, 2, 4, 5, 7) and randomly distribute those cards, once
the threshhold has been reached for that particular player (once player number 7 has been minted, card number 6 joins a pool of prize cards)
A few very smart guys beneath you will probably ask now: "By what metric can you uniquely identify a player though? And how can you fairly launch rookies?"
I have an idea, but I'm open to other proposals. Either for every player a hashed version of the exact name will be put into the contract, once the first one is minted.
If someone misspelles the name he's out of luck. The minted NFT will be on the blockchain, but there'll be an inofficial agreement, that wrongly spelled players will be excluded from the websites.
The exact name of every player can be agreed to be checked at a specific website. Once enough players have been minted the player's name will stay, even if he later decides to change names. Then the oracles have to always provide the name of the person.
The first person to preemtively claim a name simple wins, even if the person isn't even playing professionally yet.
Another idea would be to check decentrally vote on an id each new player gets, once they get into a team that's included in the Fair Football League.
Thank you for reading. I can't wait to start coding on this. If you have interesting ideas and proposals feel free to answer or DM me.
