Topic: [PRE-ANN] EmpireCoin - Gamified proof of stake altcoin platform (Read 1723 times)

Hi everyone, EmpireCoin has rebranded to PolyCash.

Check it out via https://poly.cash or check out this thread:
https://bitcointalksearch.org/topic/polycash-create-your-own-altcoin-by-gui-2955215

We have a series of daily virtual prediction market games running right now where you can vote for Trump, Clinton or Gary Johnson.  It is free to join and at least $5 in BTC is paid out to winners of each game.

Visit http://empirecoin.org or see our Mock Election 2016 thread if you are interested.

EmpireCoin Testnet is now up and running.  I will post an announcement shortly with instructions on how to install.

The free game is completely free; there's no entry fee and no prize for the winners. 

please send me a invite

EmpireCoin Web (what you see now on EmpireCoin.org) has two functions.  First, it allows you to set up and run EmpireCoin private games with any parameters.  Secondly, it functions as a client / wallet for empirecoind.  So when the EmpireCoin currency is launched, EmpireCoin Web will be open sourced and you will be able to install it on your computer as an alternative to the QT client.  (You would need to install Apache, MySQL and PHP first)

Part of the idea for launching EmpireCoin Web prior to EmpireCoin Core is so that a variety of game parameters can be tried out.  Once the currency launches, its parameters cannot change so we need to be sure to chose the best parameters right from the beginning.  Therefore we need to get a few games going now with different parameters to see how the strategy works out when a large number of people are playing.

This is a very interesting way to gage the demand of a new coin by offering a game. However, the game also requires real investments/fees to play? I know you have a free game going, but if it has a prize that's based on a chance to win, and also requires an entry fee, this belongs in the Gambling section.

I have no interest to beta test this, but I am interested to checking out what you've got once you launch. Regarding EmpireCoin, how soon are you expecting to launch the ICO?

looks interesting to try it, the payment use bitcoin or empire coin. please send me invite link for sign up because i can't sign up, thanks.

this looks really interesting iam gonna join today

Final results from the first game are listed below.

Alias	Initial balance	Final balance	Inflation adjusted profit or loss
famborghini~	2,000 coins	21,961 coins	167% profit
monbux	2,000 coins	16,817 coins	105% profit
slave	2,000 coins	6,083 coins	26% loss
tumbal1000	2,000 coins	3,833 coins	53.3% loss
changeakun	2,000 coins	3,824 coins	53.4% loss
artamara	2,000 coins	2,526 coins	69.2% loss
Parudal	2,000 coins	2,447 coins	70.2% loss

Based on the response so far it doesn't look like we'll get 20 players, so I have gone ahead and started the free game with the 7 players that we already have.

I have set blocks to a target time of 10 minutes, therefore rounds will conclude approximately every 10 hours for the next week.

Also links to several public two player games are now active on our homepage.  This means you no longer need an invitation to try out EmpireCoin - just visit EmpireCoin.org and click on one of the 2 player game links to start playing.

Hi Kakmakr, thanks for bringing up this important issue.  EmpireCoin addresses the incentive to exclude votes in two ways:

1.  Each round consists of many blocks (currently 10 blocks per round)
Assume that each mining pool has a few empires that they want to win.  These pools will therefore mine blocks that only include votes for those empires.  With a variety of mining pools winning blocks in a round, most votes should eventually be included in the round.  Recognizing that it is impractical to influence the outcome in this way, miners would therefore abandon this strategy and instead confirm all voting transactions in order to maximize their fees.

2. Proof of stake
Another risk is where mining pools do not immediately release blocks and instead build up several blocks which are released all at once, orphaning blocks which have been published by honest miners.  In Bitcoin, this is a problem because the longest chain (the chain with the most proof of work) is considered the true chain.  If this were the case in EmpireCoin, we might expect mining pools to exclude all voting transactions other than their own and mine a chain of 10 blocks which are released all at once, allowing the mining pool to keep 100% of voting rewards for the round.  However, EmpireCoin does not consider the longest chain to be the true chain, instead EmpireCoin uses a function which is a hybrid of proof of work and proof of stake.  In this case, the proof of stake component is simply the total number of votes in the potential chain.  Pools that pursue this strategy would have a small number of votes on their chain, thereby scoring poorly on proof of stake and allowing their chain to be overtaken by honest chains which score highly on proof of stake by including all voting transactions that have been published.

Also note that this thread is announcing the launch of EmpireCoin private games.  The fully decentralized EmpireCoin currency will be released separately in the Altcoin subforum.  For private games, this is not an issue since all blocks are mined by a single trusted miner with a policy of confirming all voting transactions in every block.


In the free games there is no money in the pot when the game ends and therefore you wouldn't earn bitcoins even if you do well.  For the paid games, you may either lose or win money depending on how well you do and how much money you put in.


Empires are only disqualified if they have more than 25% when the voting round ends.  So China and USA may currently be over 25% but they could still win if they are under 25% when the first round ends.  Note that the 25% is not fixed - different games may have different voting percentage caps.

Is this just an attempt to create a game to stimulate the need for a new Alt coin? < EmpireCoin > This part of this whole idea made me pull out, " As with other cryptocurrencies like Bitcoin, miners have veto authority over any transactions included in their block. Because miners have some influence on the winning empire it is possible that your votes may not be counted. "

Get a solution for that problem and I would consider playing it. No need to waste time on something that can be manipulated.

this is very interesting can i join ? anyways after checking your site looks like china and usa has disqualified
according to the site that Any empire with more than 25% of the votes is disqualified from winning the round and then the eligible empire with the most votes wins the round, it means that votes of the empire must be lower than 25 % right?

This looks very interesting. Only other game I have heard of was the dragon one. But just as someone asked before can you earn while playing it?
If you can send me an invite. I will give it a try even if you can not earn bitcoin playing it.

can I earn bitcoins also for playing this game? I am a big fan of strategy and skill based games, I want to get an invite.
thank you.
