23  Economy / Games and rounds / Mock Election 2016: Virtual prediction market. Vote Trump, Clinton or Johnson on: August 09, 2016, 11:13:00 PM


Mock Election 2016
Website: EmpireCoin.org

Mock Election 2016 is a blockchain voting game developed on the EmpireCoin platform. For more information about EmpireCoin, an open source blockchain gaming platform, please see the EmpireCoin announcement thread.  Or read this thread about one of our previous games: Red vs Blue.

Mock Election 2016 runs once per day.  Elections are held in each of the 50 states, with 2 state elections held simultaneously each hour.  Candidates accumulate electoral votes based on the states that they win.  At the end of the game, the candidate with the most electoral votes is declared the winner and players lose or win money depending on how many votes they cast for the winning candidate over the course of the game. Three candidates are included in the mock election: Donald Trump, Hillary Clinton & Gary Johnson.

At any time, players can buy more in-game coins by sending bitcoins to the game's escrow account.  For the first game, $5 worth of bitcoin has been donated to the escrow account to set the initial exchange rate.  In EmpireCoin games, in-game currencies are pegged to another currency such as dollars or bitcoins.  For Mock Election 2016, empirecoins are stored on the bitcoin blockchain but pegged to the US dollar.

At the end of the game, funds from the escrow account are split up and sent back to the players in proportion to the percentage of the in-game currency that they hold.

In this game, empirecoins experience an inflation of 10% per hour, for a total inflation of 983% by the end of the game.  Then at the end of the game, the currency supply doubles and the new coins are given out to players in proportion to the amount of the votes that they had for the winning candidate.

In each state election, players can win coins by staking their coins on the candidate that they expect to win that state.  For winning votes, players win a small number of free coins, but for losing votes, players do not lose any coins (except for transaction fees paid on their voting transactions). Unlike real elections, the candidate with the most votes does not always win the state election.  Any candidate with greater than 50% of the votes at the end of the election is disqualified, and the candidate with the next most votes wins.

You can join this game for free right now and receive 500 empirecoins.  To sign up, please visit EmpireCoin.org
Or post in this thread and I will send you an invite by PM.

To test out this new coin, we are inviting BitcoinTalk members to join this test game.

The first 4 members to join will receive in-game coins equivalent to $2 in BTC.  Please visit http://empirecoin.org

25  Bitcoin / Project Development / Coin Battles - Open source P2P voting app for the Bitcoin blockchain. on: July 05, 2016, 09:33:56 PM
Coin Battles, previously branded "EmpireCoin", is an open source P2P application which enables trustless voting on the blockchain.  In coin battles, players cast votes on the blockchain by moving coins between their own addresses.

This open source web application allows anyone to define their own protocol (aka "game") & deploy it to a blockchain such as Bitcoin.

In coin battles, players can vote on more than one option.  Stakeholders receive voting rights proportional to the coins that they hold.  This protocol also supports voting based on coin age: (ie votes = "coin blocks" or coin days destroyed). 

This idea has many applications such as:
 - Deterministic voting games
 - Parimutuel prediction markets
 - Decentralized decision making (DAO)
 - In-game sports betting

Coin battles may be defined with several different types of inflation: no inflation, linear inflation, or exponential inflation.  Currently, this project fully implements the deterministic voting application. In these games, an exponential inflation model is used and payouts are made to stakeholders by gamified proof of stake.

For more information, please read this whitepaper:
http://empirecoin.org/EmpirecoinWhitepaper.pdf

To try it out, create an account on CoinBattles.com or install empirecoin-web:
https://github.com/TeamEmpireCoin/empirecoin-web

Software development & marketing expertise is sought from the community to make this project a success.
26  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] PrezCoin: Earn BTC by voting for Clinton, Sanders or Trump. on: May 26, 2016, 01:38:15 PM
PrezCoin: First gamified altcoin backed by escrowed bitcoins.

PrezCoin is a game built on the EmpireCoin blockchain gaming platform.  In PrezCoin, you can win or lose money every hour by voting for Bernie Sanders, Donald Trump or Hillary Clinton.  Every 60 minutes (approximately), one of these 3 candidates wins a round of voting.  When a candidate wins, the total supply of prezcoins increases by 2% and the newly created coins are given out to everyone who voted for the winner.  This game will last for 500 voting rounds, or approximately 3 weeks.  Once the game is over, all Bitcoins that were paid in will be released from escrow and paid out to prezcoin holders in proportion to their final balances.  Anyone can join PrezCoin by purchasing 20 prezcoins for $10 worth of Bitcoin.  The game will start as soon as the first 10 people have joined.  To get started, please follow this link: http://empirecoin.org/prezcoin/

Rules of the Game

1. Any candidate with more than 50% of the votes when the round ends is disqualified.  The candidate with the next greatest number of votes wins.
2. Voting rounds consist of 60 blocks with blocks being mined approximately every minute.  Voting transactions are tapered by a linear decrease function.  This means that transactions confirmed in block 1 of the round count for 100%, while votes confirmed in block 30 count for 50% and votes confirmed in the final block of the round do not count at all.
3. Votes are based on the age of the UTXO being spent; therefore votes build up over time.  For example, a UTXO for 10 coins which is spent in the first block of voting round 5 will count for 40 votes if it was created in a transaction from round 1.

For more information on the EmpireCoin gaming platform, please see this thread.

PrezCoin Free

A free version of PrezCoin is also available so that you can try out PrezCoin without putting any of your money at risk.  Follow this link to try out the free game: http://empirecoin.org/prezcoin-free/

Voting pool administrators needed

PrezCoin winners are determined entirely by players' votes.  Therefore players can benefit by collaborating together to influence the outcome of voting rounds.  Players who are less active may wish to assign their voting decisions to active players without entrusting their money to anyone.  This can be accomplished through voting pools.  To set up your own voting pool, please visit the EmpireCoin API page.

Intro to EmpireCoin
Website: EmpireCoin.org

EmpireCoin is an ambitious project which aims to revolutionize the crypto community by creating a new genre of blockchain gaming.  The EmpireCoin platform functions as an altcoin simulator; each EmpireCoin game simulates an altcoin with linear or exponential inflation.  In EmpireCoin games, players compete against each other to win free coins which are created by the currency's inflation.  One empire such as China, the USA or India wins each voting round and everyone who voted for the winner receives a share of the free coins from that round.  EmpireCoin is based on a hybrid of POS & POW: some coins are created by proof of work (SHA256 hashing) while others are created by gamified proof of stake.  EmpireCoin votes accumulate based on the coins that each player holds.  For example, in a game where each voting round takes one hour, a player holding 1000 empirecoins would accumulate approximately 24,000 votes per day.  Players can choose to vote small amounts in each round or save up and cast all votes at once in order to receive a large payout.

EmpireCoin is a game of skill; the outcome for each round depends entirely on the votes of the players.  Players can gain a competitive advantage by forming a group and voting together.  This leads to complex political gameplay as different factions may form and attempt to gain control of the network.  Groups which get too large have incentive to splinter or reorganize.

Rather than trying to understand this text, you can just visit EmpireCoin.org and start playing.

EmpireCoin Web & EmpireCoin Core

This is the first public post about EmpireCoin, however this project has been in development for the past year.  EmpireCoin is made up of two main software components:

1. EmpireCoin Web - Web platform to facilitate EmpireCoin private games (Already implemented)
Games are facilitated by the house.  The house is a trusted party with the exclusive right to mine blocks, who is also responsible for guaranteeing the integrity of the game and for securely storing and releasing escrowed funds. Private games may be backed by dollars, bitcoins or any other currency.  For example, players must pay some number of dollars to the house in order to join the game, then they may buy additional coins from the house if permitted by the game's rules.  All funds paid to the house are stored in escrow and once the game ends, these funds are returned to the players in proportion to their final balances.  The house may charge a fee to the players by keeping some or all of the mined coins; any fees paid to the house must be disclosed up front for the sake of transparency.

2. EmpireCoin Core - Decentralized currency & protocol (Partially implemented)
In this stage, the EmpireCoin gaming platform will be completely decentralized through the creation of a single EmpireCoin currency which can facilitate arbitrary EmpireCoin games.  Players must purchase and then burn empirecoins to set up a game.  Once the game ends, the EmpireCoin protocol will re-create the burned coins and pay them out to the players.

EmpireCoin API
(Already implemented)

EmpireCoin players may benefit by using automated methods to cast their votes.  Several automated strategies are already built into EmpireCoin's web platform.  Players can plan out their votes in advance or they can select and configure a strategy to automatically & strategically cast their votes.  Players can also code up a custom voting strategy by hosting an API endpoint on their own server.  This API is currently pull based: players enter their API endpoint URL into their web wallet and then the EmpireCoin server will hit this URL at regular intervals and apply it's voting logic.

Team-based Games
(Not yet implemented)

In EmpireCoin team games, every player is assigned to a team.  At the end of the game, the team with the greatest net worth wins all the escrowed funds and players from the other teams walk away with nothing.

Virtual prediction markets
(Not yet implemented)

By default, EmpireCoin games are set up with 16 empires as voting options (16 of the biggest nations in the world).  However, EmpireCoin can support any type and number of voting options.  By setting up an EmpireCoin game with voting options such as presidential candidates, football players, NBA teams, stocks or currencies, EmpireCoin can function as a form of virtual prediction market.  Unlike traditional prediction markets, the outcome of events in EmpireCoin may be influenced by real world events, but outcomes are not exclusively determined by them.  Real world events may boost the probability of a certain outcome winning but ultimately outcomes are determined by the votes of the players.  Unlike traditional prediction markets, players do not lose in-game currency if they vote incorrectly.  Instead, the high inflation of EmpireCoin's in-game currencies discourages inaction, encouraging players to bet and rewarding those who cast winning votes.

Our Team

Joey Rich is EmpireCoin's concept creator and lead developer of the EmpireCoin web platform.  He has previously engaged the crypto community with projects like BuyBitcoins.com, SellBitcoins.com and BitcoinGiftCard.org.  Joey has several years of corporate software development experience with companies like Gameday Housing and FanPay.org.  He also operates OpenOffCampus.com, a real estate advertising service and is one of Bitcoin's earliest adopters.

Madisco X has chosen to remain anonymous; he is the lead developer of EmpireCoin Core, the decentralized currency & protocol which will facilitate fully decentralized EmpireCoin games.  Madisco is an altcoin enthusiast who has contributed to several high profile open source crypto projects.

Project Milestones

- EmpireCoin web platform opens for limited testing; several invite-only games will be conducted to try out EmpireCoin strategy.
- EmpireCoin web platform is fully opened to the public, allowing anyone to test the platform and play games.
- EmpireCoin Initial Coin offering (ICO) is held.  Funds raised from the ICO will be used to develop both EmpireCoin Web and EmpireCoin Core.  In exchange for their funds, ICO investor will receive shares of the EmpireCoin currency.  Since EmpireCoin Core will be incomplete at the time of the ICO, shares will be given out via an EmpireCoin private game.
- EmpireCoin Core is released. When this happens, the private game mentioned above will be migrated to the fully decentralized EmpireCoin currency; real empirecoins will be given out based on the balances of the private game.

Try it Out

Today I would like to kick off EmpireCoin with a handful of EmpireCoin private games.  The first game will start once 20 players have joined and paid 0.05 BTC each.  This game will last for 20, twenty minute rounds or approximately 6.5 hours in total.  For users who are hesitant to risk real money, a free 20 player game has also been set up.  Players should be sure to enter their planned votes ahead of time to avoid missing out on votes.  Once this paid game is complete, the 1 BTC which in escrow will be divided up and given out to all of the players based on their final balances.  For more information, please visit our home page, EmpireCoin.org

Currently all games are invite only.  To request an invitation, please post on this thread or send me a personal message.  Additional games can be created upon request.

Questions and suggestions are welcome in this thread.  Thanks in advance for trying EmpireCoin.

29  Economy / Speculation / What caused the $12.50 spike today? on: September 11, 2011, 06:51:24 PM
Here's my theory about what happened today:

People who used the same password on this Bitcoin forums as for their MtGox accounts had their MtGox accounts broken into.  To steal money from these new accounts, hackers logged into their own accounts and placed large sell orders at around $12.  Then they logged into the compromised accounts and placed large buy orders at $12.  These orders and anything under $12 were fulfilled, so the hackers were able to sell their own bitcoins for $10+ prices.  And people whose accounts were compromised will log in to find that they purchased a bunch of overpriced bitcoins.
30  Bitcoin / Development & Technical Discussion / Idea for "Bitcoin Stocks" on: April 12, 2011, 03:58:51 AM
I'm not sure if this business idea is compatible with the Bitcoin transfer system:

Suppose someone starts a small business and wants people to invest in his/her idea, but the business is too small for an IPO.
This person could use Bitcoins instead of a traditional stock structure.  This person would take 100 (or any number really) of his/her
existing bitcoins and re-brand them as 100 bitcoin stocks.  Anyone interested in investing in this person's business could attempt to
buy these bitcoin stocks from the owner.  These bitcoin stocks could be purchased with normal bitcoins or with any other form of
payment.  Essentially the idea here is to allow people to take their existing bitcoins and turn them into discrete, customizable entities
which could be traded through the existing Bitcoin network.

This would require some major changes to Bitcoin.  Most importantly, a bitcoin transfer of this kind would have to contain extra
information: the stock ID associated with the transfer.  It would also be necessary to have an online reference database
where people would be able to look up information associated with this stock ID.

I just finished writing a simple website which accepts credit card payments and gives out bitcoins.
I already have an Authorize.net credit card account, so I was able to implement this payment system
pretty quickly.  Please send me any suggestions that you have for the site.  Beware that
I have not yet added an SSL certificate to this site because of the cost, so don't use my website
if you're on an unsecured wifi network.
