High Stakes Bitcoin Raffle Lottery 64 Number Character Alphanumeric Secret, the SHA-256 Hash is: aec6a9ff8b868f3065face8de389a1f76b03dbda7af4e621a3d9aac97aeb199c

Bitcoin address for the current raffle: 1KCSsL7rRHH6qkRS5wSwWuzAcZ7zNYnNDg (http://blockchain.info/address/1KCSsL7rRHH6qkRS5wSwWuzAcZ7zNYnNDg)

Deadline: 1st confirmation (blockchain) of the 10th bet of .1 BTC sent to the address shown above.

Entry ticket price (bet): .1 BTC (ten bitcents)

-=[  What is this all about? ]=-

This is an experiment (that evolved from the essay that is shown here: https://bitcointalk.org/index.php?topic=409660.0 (https://bitcointalk.org/index.php?topic=409660.0)) in order to study the effects of a game that is:

* Anonymous;
* Raffle lotto using bitcoins - Always a Winner;
* Transparent;
* Instant play (No Registration Required);
* Provably Fair (cheat proof);
* Cryptographically Verifiable;
* Blockchain Spamless...

and also:

* Limited tickets: people get better winning odds and probabilities;
* Progressive jackpots: "house tickets" win the game (some times) and roll over all the current jackpot to fill next round or game;
* The game becomes +EV for gamblers to play sometimes.
* and much more...

About Provably Fairness:

By using bitcoins for raffles several unique features are possible:

* The players identities are unknown but all the tickets are known;
* Every ticket purchased can be viewed by everyone along with the senders bitcoin address;
* Each ticket is permanent and can't be altered because it is stored inside the blockchain;
* The pot size can not be faked as anyone can check the lottery address and verify it;

Most importantly, it's impossible to manipulate who wins or fake a payment to the wrong person because:

* Each ticket has a unique number that is permanent (transaction hash);
* Using some block data and hashing with SHA-256;
* The transaction hashes stored in the blockchain are then used to calculate the winner in an impossible to predict way;
* A secret known only by me is hashed and published so I can not change the secret later;
* The secret is then published after the deadline;
* The winnings are then sent to the EXACT same address that bought the ticket.

All of this can be monitored and verified by anyone and is recorded in the blockchain.

-=[ How to play this Raffle Lotto? ]=-

To buy one ticket, send the exact amount of .1 BTC (ten bitcents) to the bitcoin address shown above.

P.s: you may use the following bitcoin wallet software: Bitcoin-Qt; Electrum; Armory; MultiBit; Hive. For web wallets we recommend only using Blockchain.

DO NOT use wallets from exchanges nor any shared wallets such as localbitcoins, mining addresses etc.

The prize will be sent to the same address that previously sent the coins from (in order to avoid fraud). If sent from more than one address, the prize will be sent to one of them.

All payments received prior to deadline is part of the raffle's jackpot.

Payments sent after that deadline will be refunded to the same original sent address (a tx fee of .0001 BTC will be deducted) after the draw.

-=[ Technical and operational details ]=-

This game consists of 4 rounds;

Current entry bet is .1 BTC (ten bitcents);

There are Limited tickets: 10 tickets currently. Players get better winning odds and probabilities;

Max number of players tickets: 10 (ten).

There are "House Tickets" and Progressive jackpots: "house tickets" win the game (some times) and roll over all the current round's jackpot to fill next round or game. House tickets never get the prize just roll it over to next round's jackpot.

1st round: there are 5 house tickets - Total tickets (players + house) = 15;

2nd round: there are 3 house tickets - Total tickets (players + house) = 13;

3rd round: there is 2 house ticket - Total tickets (players + house) = 12;

4th round: no house ticket available - Total tickets (only players) = 10.

P.s.: all house tickets are created hashing pre generated secrets with High Stakes Bitcoin Raffle Lottery secret and the following/next secret revealed at "Little Bit at a Time" (https://lbaat.net/) right after the tenth (last before draw) ticket bought (and confirmed) here. You can verify their fairness too. Those tickets' secrets are not generated as transactions but you may see and verify all of them (SHA-256 hashed) here: http://pastebin.com/duibPqdB (http://pastebin.com/duibPqdB)

If a player's ticket is chosen instead of a house ticket in any round, the prize is paid to that player and the raffle starts from 1st round.

Drawing: after the draw all tickets and their hashes will be posted along with the winner.

The player will have the secret by then and will be able to compute for his own ticket.

Here goes how I will compute your hashes - and you'll be able to verify it by yourselves:

1. Get your Transaction ID;

2. Get the secret revealed here for each round;

3. Get the secret revealed at lbaat.net (and published here afterwards) for each round;

4. Concatenate them (generating the tickets) and Hash them together (TXID&SECRET1&SECRET2) as one string;

5. Sort the hashes;

The winner is the hash with the lowest value (starts with the lowest numbers left-to-right).

Secrets to be used:

High Stakes Bitcoin Raffle Lottery 64 Character Alphanumeric Secret: the SHA-256 Hash is shown above;

"Little Bit at a Time" Secret: will be the following secret revealed at https://lbaat.net (https://lbaat.net) right after the tenth (last before draw) ticket bought (and confirmed at blockchain) here. I.e.: next secret shown after last valid entry ticket bought by player. The reference moment will be taken from tx time at blockchain.info.

They publish one secret every hour, and each one is the hash of the next one. All previous secrets are shown at the following URL: https://lbaat.net/secrets (https://lbaat.net/secrets)

i.e.: If you send .1 BTC and bought one ticket then I will take your transaction ID and replicate the process described above.

If you send .1, then your transaction id is used like this:

sha256sum(TXIDSECRET1SECRET2)

Where:

TXID = transaction id in hex as it appears in bitcoin-qt or blockchain;

SECRET1 = High Stakes Bitcoin Raffle Lottery secret;

SECRET2 = "Little Bit at a Time" Secret;

* The winner is the hash with the lowest value (starts with the lowest numbers left-to-right);

* Payout: 85% of Jackpot (after House Rake deduction);

* House Rake (% of pot): 1st Round = 0; 2nd Round = .5%; 3rd Round = 1%; 4th Round = 2%;


-=[ Frequently Asked Questions - FAQ ]=-

What's with all the secrets?

Their reason to be is to be Provably Fair and Cheat Proof. I have one secret and there is a secret that is generated from someone else (that I don't know what will it be). All secrets are verifiable after they are published. All secrets from this raffle game are available on the list (SHA-256 hashed) as seen here: http://pastebin.com/NMgAZkLK (http://pastebin.com/NMgAZkLK)

How much is the payout?

The total prize funds is allocated as follows:

85% (after House Rake deduction) of the funds goes to the current jackpot. This is what the winner receives (minus tx fee).

The remaining funds (~15%) goes to the next jackpot, for the next round and is used any bitcoin transaction fees.

Just some reminders:

1. If you don't like the rules, don't play it;
2. I'm gonna do all the hashing manually;
3. Games start with 15% of whatever amount the previous game had;
4. If I change or update the rules, they will take effect right on the next game after publishing the changes. It will not affect the current game nor it's 4 rounds;

Although I said you can send from multiple addresses, as that's how bitcoin works, I would prefer you send your bet from a single one.

What is the purpose of the 85% / 15% deal?

There are two purposes for this.

1. To ensure that the next game/round starts with something;
2. To prevent someone from attempting to buy all the tickets. You can actually buy 100% of them, but the prize you'll get is only 85%.

How much is the House Edge?

There is no house edge! This is like a Peer-to-Peer (P2P) game (as Poker). There is only (a small) house rake for each and every round (except 1st round).

Why is the house rake so small? Are you a scammer?
 
Because this is an experiment and I'm not in for the coins. I'm in for studying the statistical and mathematical behavior and effects of this experiment. That's why the house rake is that small, just to afford the costs of running this experiment. And no! I am not a scammer that's going to run away with your coins!

What are my winning probabilities for each round?

For one single ticket the winning probabilities are:

1st Round = 1/15 = ~6.7%

2nd Round = 1/13 = ~7.7%

3rd Round = 1/12 = ~8.3%

4th Round = 1/10 = 10%

Will there be another game after this one?

Yes. As soon as all tickets are bought I'll draw, send the coins to the winner, roll the pot over and start a new round or game. You just need to follow this topic.

What if this forum goes offline?

If bitcointalk goes offline for more than 48h I'll refund all coins sent to the current round. Otherwise the game goes on.

Is there no deadline for each game/round?

There is. But it's not measured in time. It's measured in actions: it is set after the 1st confirmation (at blockchain) of the 10th bet of .1 BTC sent to the address shown above (last valid entry ticket bought by player).

How is the refund policy?

Payments sent after the deadline will be refunded to the same original sent address (a tx fee of .0001 BTC will be deducted) after the draw.
P.s.: all sent amount different than the multiple of one entry ticket price (.1 BTC) will be considered as donation to the jackpot (not generating additional tickets) and won't be available for refund anymore.

What happens if we don't get enough ticket buyers?

In that specific case all tickets bought will be refunded to the same original sent address (a tx fee of .0001 BTC will be deducted).

Is there any escrow to guarantee the refund of my tickets?

Yes, there is. See detailed info here: https://bitcointalk.org/index.php?topic=567454.msg6182165#msg6182165 (https://bitcointalk.org/index.php?topic=567454.msg6182165#msg6182165)

I wanna buy two or more tickets. May I buy all of them in one single transaction?

I ask you not to do it in one transaction because it changes the hash calculation method. But if you (stubbornly) still do it, I'll have to add numbers to you transaction id hash in order to generate the tickets.

i.e.: you buy 5 tickets with one single transaction and you get a hash transaction of "TXID". Then I'll add the numbers of tickets bought by you after it.

TXID01; TXID02; TXID03; TXID04 and TXID05.

When hashing (draw): sha256sum(TXID00SECRET1SECRET2)

Can I send a HUGE amount of coins in order to buy tickets and join as many games and rounds as possible?

Please do not do it. Every game (consisting of 4 rounds or less) will be running with a different bitcoin address.

Is every process automated?

No. In fact it's all manually performed.

How do you generate the house tickets?

Almost the same way it's done for players' tickets. All house tickets are created hashing pre generated secrets with the High Stakes Bitcoin Raffle Lottery Secret and the "Little Bit at a Time" Secret set for each round and revealed after all draws. You can verify their fairness too. Those tickets' secrets are not generated as transactions but you may see and verify all of them (SHA-256 hashed) here: http://pastebin.com/duibPqdB (http://pastebin.com/duibPqdB)

Verifying: sha256sum(HOUSETICKETSECRETSECRET1SECRET2)

Where:

HOUSETICKETSECRET = pre generated secrets. Those tickets' secrets are not generated as transactions but you may see and verify all of them (SHA-256 hashed) here: http://pastebin.com/duibPqdB (http://pastebin.com/duibPqdB)

SECRET1 = High Stakes Bitcoin Raffle Lottery secret;

SECRET2 = "Little Bit at a Time" Secret.

Do you have a website for this game?

Not yet. This is an experiment, a (almost academic) case study and a work in progress. It's not a priority yet.

I have a doubt that is not listed here!

Feel free to ask me so!

P.s.: I wanna thank forum member Dabs (https://bitcointalk.org/index.php?action=profile;u=54791) for the support (this raffle game evolved from his "Low Hash Lotto" (https://bitcointalk.org/index.php?topic=212855) and some notes have been taken from his original ideas and texts) and all members from the community as well for the positive feedback. Thank you so much!

So, lets have some fun!

Ok, I didn't read all your first post because it is really long. So forgive me if my questions was covered in it.

But this looks like too easy money, as far I could see, there will be 10 tickets of 0.1, so I just need to send 0.1 from 10 different address (1 BTC total) and I will receive 8.5 BTC (after the house rake). Am I right?


Another thing, I couldn't see the point of the house rake. on the first draw the winner will receive 8.5 BTC, on the second draw, the winner will receive 9.775 BTC, on the third draw 9.96625. As you could see, the winnings will tend to 10 BTC.
So, why the need of house rake?

If a house ticket is not chosen when draw, 85% (~7.65) goes to winner.

There's only one draw per round and only one winner per draw. And the prize is always 85% of jackpot.

Didn't understood the math. 85% of 10 BTC = 8.5 BTC


There's only one draw per round and only one winner per draw. And the prize is always 85% of jackpot.

Yes, I understood that.


I think you didn't get my point.

ok, now I see that will be house tickets in the initials rounds. So lets do the math again:

You are giving 9 BTC for the first round, so, if I send 1 BTC and I win (66% chance), I will receive 8.5 BTC, if the house win the amount will be available for the next round.

so I will send another 1 BTC for the second round, the total jackpot will be 11 BTC, if I win (76.92% chance) I will receive 11 - 0.5% = 10.945 * 85% = 9.30325 BTC. if the house wins, supposing you will get the house rake from the total jackpot, 10.945 will be available for the next round.

so I will send another 1 BTC for the third round, the total jackpot will be 11.945 BTC, if I win (0.8333%) I will receive 11.945 - 1% = 11.82555 * 85% = 10.0517175 BTC. if the house wins, supposing you will get the house rake from the total jackpot, 11.82555 will be available for the next round.

And on the forth round, as this round will not have house tickets I will have paid a total of 4 BTC and will receive a total of 10.68368315 BTC.

Still easy money.

What do you mean by "No escrow supported"

Simply give one BTC to an escrow and if you run away , all the BTC will be guaranteed back.

Currently , you have a huge claim , but you could just steal 1 BTC.

The 1 BTC can stay permanently with the escrow , for as long as you are running this and it would not affect the outcomes of this game in any way.

You understood the game well.

But do not forget: you're gonna compete with other players as well...

The full pot is just a "1st game promotion" and it's a contribution from the project's sponsors.

BTW, for this experiment to last longer, I'm thinking about splitting the 9 BTC within 3 games.

[Update] So we did it that way... so not only this 1st game gets +EV but also those yet to come...

We're working to have an escrow for the first (at least 10) games.

What I said is that due to the progressive jackpot nature of this experiment, It's difficult to run the whole process with (a dedicated) escrow.

But we're gonna try to send each round 1 BTC as players' garantee.

Hi,

I've been contacted as escrow. Here is the contract I have PM'd to OP:

http://pastebin.com/raw.php?i=xqhmNfzj

I'll let OP decide who wins. If there is any claim, unless there is a signed bitcoin message, the funds go back to the address that sent them (for the prize.) Which means I'll have to check what was sent to the other non-escrowed bitcoin address.

I'll merely hold 1 BTC as guarantee.

Thanks for playing!

Round 2 starts in a few moments.

P.s.: I'm looking for a way to generate a random string from www.random.org (or similar site). I'm searching for a mode that allows me to select a pregenerated randomization based on randomness generated some time in the past so others will be allowed to replay a given sequence at a later stage, and multiple parties will be allowed in different locations to get the same string. I want a pregenerated randomization in order that handles more than 1 draw a day.

Contributions and ideas are apreciated!

Why the past? The current game should get it from a future date, so no one (not even the house) knows who will win until the draw. Otherwise, someone will game your game... you know, and win all the time.

In fact, when I said "past", I meant the "other two modes" of string generator available at random.org as explained here: http://www.random.org/faq/#Q2.6 (http://www.random.org/faq/#Q2.6)

You used one mode at you lotto ("Using pregenerated randomization from date") and that's what I am using here right now.

As they mention:

Quote
The other two modes allow you to select a pregenerated randomization, which means that your numbers or strings will be based on randomness generated by RANDOM.ORG some time in the past. These modes allows you to replay a given sequence of numbers at a later stage, and allows multiple parties in different locations to get the same numbers in a predictable fashion. These modes effectively turn RANDOM.ORG into a pseudo-random number generator.

P.s.: I'm thinking about using the third mode ("Using pregenerated randomization based on persistent identifier"). Maybe the identifier might be my secret for each round...

A better approach (for multiple draws per day) might be replacing the string from random.org by the following/next secret revealed at "Little Bit at a Time" (https://lbaat.net/) after the tenth (last before draw) ticket bought (and confirmed) here.

I guess I'll go for that way in order to maintain a good scenario of Provably Fairness...

What do you think about it?

Note: Gentlemen, I'll release 2nd round in a few hours after thinking a bit more about this "random stuff" and Provably Fair dilemma.

Thanks in advance for comprehending.

Oh yah, it's past and available after that particular date. So I set all my draws in a future date. When that passes, you can now get the result, and so can everyone else.

For example:
http://www.random.org/strings/?num=10&len=10&digits=on&upperalpha=on&loweralpha=on&unique=off&format=plain&rnd=date.2014-04-17

gives

l30MM2ci3N
roRhICzooM
iVjUmb2KGF
jQSjMhXIrV
tjy5ZP3RYC
1eIuBUbXTu

But only from today onwards. Yesterday, that data was not available.

http://www.random.org/strings/?num=10&len=10&digits=on&upperalpha=on&loweralpha=on&unique=off&format=plain&rnd=date.2024-04-17

gives

Error: No randomization exists for that date

Because the year is set at 2024. No matter how hard you try, you won't figure it out until 10 years from today.

Using the third mode is just as good as having your own secret and hashed with SHA256 (or whatever hash algo you use.)

The Little Bit At A Time is good for several draws per day. Or a maximum of 1 per hour. If you want practically unlimited draws per day, you can just use a sequence for the day (like just-dice nonce). Add 001 for the first draw. Add 002 for the second draw. You get to make up to a thousand draws per day if you stick to 3 numeric digits.

As long as one secret is not known to you, the operator / owner, then it is Provably Fair. If you know it (like using the third mode), then ... you can win all the time if you wanted to.

The only thing is that you have to wait for any secrets to be revealed, the next day, or the next hour.

Post by: Financisto on April 18, 2014, 02:05:51 AM
Thanks Dabs for the insights!

I'll replace the random string generator by the "Little Bit at a Time" hourly secrets, so when the last ticket bought (tenth ticket) is confirmed we add the next/following (future) hour secret to the "calculation". That way we'll be able to draw more than once a day and still stay true to the Provably Fair "philosophy"!

OP updated.

2nd Round is now running.

Enjoy everybody!

I'm confused, is this confirmed set up in a way where the site operator cannot know who will win in the future?

It is set up in a way that:

1st: there's your Transaction ID hash that in no way I can predict what will it be.

2st: I have one secret that only I know which is and I do not reveal it to anyone before draw. You cannot predict it.

3rd: There's a (future) secret at "Little Bit at a Time" that you and I are unable to know before it is revealed (after the round is over here).

Those are the (unpredictable) processes in order to generate the final (unpredictable) hashes to pick a winner.

Correct!

The first is to prevent the operator as the operator from cheating.
The second is to prevent the player from cheating.
The third is to prevent both the operator (either as the operator or pretending to be a player) and the other players from cheating.

No one, not the players, or the site operator can know who will win in the future until after the secrets have been revealed, and then everyone, even none players, can calculate who is the winner.

This is similar to how I ran mine, and almost similar to how an older game was run (which used real life lotto draws as a source of unpredictable numbers.)

Thank you Dabs for posting additional detailed info.

For those new to this kind of Provably Fair game, take a look at Dabs own experiment.

The URL is posted right at the end of OP as reference.

Additional note: no one knows who the winner will be, but buying more tickets increase your winning probability for a specific round to get the pot!  ;)

Good luck for everybody!

Bought them all but sent it from the wrong address and in bulk by mistake... 15ieHJ7eK5gJ5dfeZiWCz5bGkFJS52Pomy  is the address where they were meant to come from and I could have dooglus from just-dice verify this if you need to.

Exceptionally, I'll refund the last 2 transactions to their respective sent addresses.

Please read the FAQ section (OP) where it is written:

Quote
How is the refund policy?

Payments sent after the deadline will be refunded to the same original sent address (a tx fee of .0001 BTC will be deducted) after the draw.
P.s.: all sent amount different than the multiple of one entry ticket price (.1 BTC) will be considered as donation to the jackpot (not generating additional tickets) and won't be available for refund anymore.

[...]

I wanna buy two or more tickets. May I buy all of them in one single transaction?

I ask you not to do it in one transaction because it changes the hash calculation method. But if you (stubbornly) still do it, I'll have to add numbers to you transaction id hash in order to generate the tickets.

i.e.: you buy 5 tickets with one single transaction and you get a hash transaction of "TXID". Then I'll add the numbers of tickets bought by you after it.

TXID01; TXID02; TXID03; TXID04 and TXID05.

When hashing (draw): sha256sum(TXID00SECRET1SECRET2)

[Update]

Refund sent as stated before...

Since you're doing it anyway, you might as well create the "multiple tickets in single transaction" method. If there is only one ticket, then just add one number.

That's what is stated above (FAQ). Although I'd rather treat it as an exception than take it as a general rule.

It makes things simpler and easier!  ;)

Well my 0.4 coins got stolen by someone else. FML.  I told the OP to have dooglus mediate this one (who is probably the most trusted person in bitcoin) but he sent them back to the hot wallet (which I said was a bad idea) where they were picked up by some random.

I'm done with this game now after this round and my current bid. I realize that even though I did mostly fuck up, it was extremely easy to right and simple customer support issues should be resolved correctly or else there's bound to be future issues which I personally don't want to deal with. But gl to anyone else.

I've contacted dooglus in order to find a way to solve your problem.

Maybe in the future. We're just testing this idea in it's earlier stages.

Thanks for the suggestion.

Good luck everybody!

Will there be limitless tickets in the future and its rather based on some kind of time deadline?  I think that would make it much more interesting.

Well, I do not think so.

Our friend Mr. Dabs did that lotto variation before. Search for "Low Hash Lotto" here.

We're trying to test different variations of it in order to test games that are not so -EV (negative expected value) for gamblers to play.

As said previously: this is just an experiment... :)
