Topic: ETHER-ARTS.IO : WORLD'S FIRST ERC721 ART LOTTERY CARD. (Read 297 times)

We are very proud that we have started our service on mainnet officially!
Collect ether-arts cards, and get a big reward!
Our first winner lottery is April 25th, 2019.

Hello Ailmand!
We sell art lottery cards. For every 10 days the smart contract picks up the winner cards and give a ethereum reward to their owners. We accumulate 50% of the sales amount of the card to prepare the compensation money.
Each card has a color attribute, and the total amount of each art card is determined and limited according to its color attribute. Once the winner card is selected, the smart contract retrieves the wallet addresses that stores winner cards. And it assigns a certain percentage of the compensation ethereums to the winner's wallet address.

We choose two types of cards as the winner, and the player who owns both two winner cards becomes the first prize winner. (who owns one of two winner cards will be the second winner)

As the stage progresses, the difficulty of the game will increase.
This can makes big reward pool, but could be extremely hard to win.

To solve the difficulty problem, we used the following method.
1. Choose one winner card from the full range ever issued.
2. The other one winner card is selected from the N most recently issued cards.

We can control the difficulty of the game by adjusting the value of N. This method also ensures that all cards issued in the past do not lose their values.

This is our system design.
If you have any question, please feel free to ask
Thank you for your interest!

Okay, I moved this thread to Service Announcements(Altcoins). Thanks for let me know

Oh so that's how it is.  Thank you for the information.
Oh yeah, I almost forgot it that sites that are posted in here should only mask Bitcoin payment.

Since your site is based on ERC721, so it should not be here. I have reported it to mod but it will be better if you moved it to Service Announcements (Altcoins) instead of waiting for Mod to move it.
This gambling board is dedicated to any gambling projects that accepts bitcoin as one of the payment method, so you have to follow the rules.

Hello Zadicar, I don't think this is a ponzi schemed dapp. Since this's a lottery ticket basically, we have to gather ethers for reward pool. All game participants will participate in the game knowing that their purchase amount is used as part of the reward. I think this is not a ponzi but a gamble. And we must have a systematic way to prevent our card's value from plunging after the lottery draw. This is the reason for reusing the card.

Hello virasog! Ether-arts cards are collectible card like cryptokitties, but they have very special characteristics. If you have a certain combination of cards, and you are lucky enough (if the winning cards match your own cards), you'll get the rewards from the rewards pool. Since this card is ERC721 collectible, it is not destroyed nor functionally limited after winner selection event. you can use it again and again.

I didnt tried out to check the game yet i do need to install metamask first but i do try to read up the definitions above. These erc smartcontract games are just like ponzis and do
really make me reminds of FOMO3D as far as i remember.

We have made a lot of effort to balance between the functions of collectibles and lotteries. Traditionally, lottery tickets should be operated once, but in order not to lose value as a collectible, the this lottery card should not be limited to one time. So we draw two cards each time we draw. One is drawn from all cards issued so far, and the other is designed to be drawn from recently issued cards. Old cards will be required to win 1st place. Players who owns both two winner cards will be first winner. and players who owns just one out of 2 winner cards will be second winner.

Yes nauane, Sorry to say that, We have posted this contents on ANN forum and BOUNTY forum two weeks ago.

Unfortunately  I found this sub forum today(because I'm newbie here.. please understand), so I posted it several minutes ago and lots of bounty has closed already.

I can see most of the bounty is closed and only the youtube bounty and promoting the site to other crypto platforms is available. As i see you posted this thread a while ago so when these other bounties got filled already ?

ERC721 are unique tokens on the Ethereum blockchain while ERC 20 is the class of the identical tokens. Its a bit complicated topic but here I don't get how this lottery system is related to ERC721 ?

Care to explain the whole concept. So, people buy lottery cards, which is like a collection of paintings, which doesn't expire. So as more and more players are there, the prizes gets lesser. And, 50% of the proceeds from the sales will go to the price pool, which will be divided among players who won the lottery? I am confused. 

ERC721 is ethereum's crypto-collectible protocol standard. cryptokitties are the example using it.
I think my bad english makes you confusing. sorry for that 

This is the first time I saw a lottery card I don't understand the concept of it. I don't know what is ERC721? Can someone explain that?

Thank you for your helpful advice. In fact, I have been working alone and have been learning a lot for over six months. It was a hobby at first, but I made a lot of effort because I wanted to do it properly. It seems that there are a lot of errors in the English white paper because I am not native. I will fix it with the help of a professional translator ASAP. The ETHER-ARTS card can be traded through our web site. I have integrated user-to-user transaction functionality on our website. And although it is not yet implemented, it will be exchangable via ERC721 exchanges such as Opensea.io in the near future.

Hello Okala! This is a new lottery game and our lottery ticket is ERC721 crypto collectible such as cryptokitties. If any player owns this card, he will qualified to join our game. Every 10 days, we select winners who owns winner cards, and reward them using ethereum reward pool that is accumulated by 50% of total sales amounts. I have posted here because I think our ecosystem is like a gambling. If lots of people here think that this is not acceptable on this place, I'll move this thread somewhere else. Thanks for let me know.

I like it that instead of some abstract animation or half-naked females you have artwork of various famous people! It's cool when people can learn while playing, and these cards will at least do the job of familiarising gamblers with art.
I get it that your lottery works on a smart contract and thus requires Metamask, but I think it would be better if at least people could access the website without turning it on.
You might also consider hiring someone who speaks proper English to proofread your Whitepaper. It has many mistakes.
I'm also wondering what is the status of the cards people buy with ethereum. Are they functioning like a token inside of the game? Can people, say, exchange cards for ethereum somewhere?

Your team offer just lottery cards or you also provide gambling games on the site, am a little confused about this at one point I took it for a new ERC20 token and at some point again as a lottery cards sales point but you did not mention any thing like gambling and this is gambling section, can you please address my confusion.

We'll start our service on mainnet tomorrow. Please come and have a look
Please note that we are now on rinkeby test network. New contracts on mainnet is under testing now.
