1  Other / Meta / Suggestion: Show "Last edit" info beside the original post info. on: May 16, 2016, 12:43:19 PM
On top of each post we have two possible infos: the date from the original post and the date from last edit.

Instead of being hidden "inside" the original post info and only shown when we mouseover the original post info, I suggest both info could be visible side by side like this example:

Original post: November 01, 2015, 02:12:45 PM - Last edit: November 11, 2015, 02:43:34 PM

Some users get confused trying to figure out if post is old or if it's been updated recently...

I guess that would be a very simple change in the code.
2  Other / Meta / Creation of a new .onion url for bitcointalk.org? on: September 02, 2015, 01:59:54 AM
I'd like to suggest the creation of an .onion url for bitcointalk.org as an additional layer and a security measure against ddos attacks and (maybe) gov attacks (why not?).

I think that would be an interesting idea so the regular forum could suggest that all TOR users should use the onion address the same way blockchain.info does today.

The .onion link will also serve as an backup site.

P.s. I don't know the costs related to that possible implementation.
3  Bitcoin / Project Development / ⛓LIST⛓ Brainwallet & Paper Wallet projects. on: August 28, 2015, 07:20:20 AM
I've just started the following list in order to promote development of good open-source tools to provide secure and alternate ways to create cryptocurrencies' wallets and addresses – specially the popular known tools entitled “Paper Wallet” and “Brainwallet”.

Great tools have been created all those past years by skilled programmers and by a community of dedicated volunteers. So I decided to create this list as means to promote a “healthy” competition among those programmers, so cryptocurrency users and all the related community can benefit from that.

What is:

Paper Wallet ← click to learn the basics about it.

Brainwallet ← click to learn the basics about it.

If you think your project deserve to be listed here PM me. Requirements for participants:

1st) The project must be a Brainwallet or Paper wallet of some kind of cryptocurrency or crypto-asset;

2nd) The project must be open-source;

3rd) The project's code must be available at https://github.com

4th) The project can't be a newer identical clone version of an (already existing other person's) older original app (it must have - at least - one reasonable innovation or add-on).

All parameters here are subject to change, this is a work in progress...

If you got an idea, share with us!

This is not meant to be an exhaustive list, just a compilation of similar projects and source of data for the community about development of those mentioned tools. This list will be updated frequently.

IMPORTANT STATEMENT: This List is offered without any warranty whatsoever; we do not guarantee the ideal operation or funcionality of no tool nor app mentioned here. No professional code auditing were performed by us. If you lose your coins using one or any of those tools, we are not to be blamed and we're not responsible for it. We'd be very sorry, but we cannot help you about that. Cryptocurrencies are new stuff yet, so many experiments are still in early stages. We also cannot guarantee any member's reliability and that your coins will be 100% safe 100% of the time (even in the future). This is just a simple list and a competition. Due diligence, research, revision, auditing is still necessary. Be smart and do your job. Use those tools/apps at your own risk!

Note one: please read and pay attention to the above statement and don't ever post here something like “Someone stole my coins because my password is 'coin123'”

Note two: please support those projects donating some coins.

4  Economy / Gambling / [Doubt] (Powered by bitcoin) Bookmakers accepting SUMO Wrestling stakes? on: May 02, 2014, 05:56:17 AM
Does anyone know or ever heard about some Bookmakers that accepts SUMO Wrestling wagers?

Couldn't find any nowadays, but I think it would be an interesting (bitcoin powered) gambling option...

BTW it's even hard to find traditional bookers with SUMO added as an alternative sport to bet.

-=[ High Stakes Bitcoin Raffle Lottery | Limited Tickets | Good Winning Odds | No House Edge | Progressive Jackpot | Provably Fair ]=-

-=[ Game #1 | Round: 2nd | Escrow: Available | Current Jackpot: 4.0001 BTC | Status: Over ]=-

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

Bitcoin address for the current raffle: 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) 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" 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

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 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

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

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

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

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

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 for the support (this raffle game evolved from his "Low Hash Lotto" 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!

7  Economy / Gambling / [IDEA] +EV (Positive Expected Value) P2P Raffle Games (PeerBet Style). on: January 11, 2014, 05:19:34 AM
Greetings!

I'm a big fan of Raffle games available out there, and the most innovative by far (IMHO) is PeerBet at the time I'm writting this.

They are the 1st known 0EV (Neutral Expected Value) and zero house edge for gamblers to play against each other.

I've got an hypothetical idea that may seem interesting in the beginning. It might give that inovation one step beyond it is today.

House tickets, additional rounds, progressive jackpots, jackpot roll overs = +EV (Positive Expected Value) Peer-to-Peer Raffle Games.

I've been testing a new "generation" prototype of raffle games in order to achieve some interesting and innovative features:

a) Limited tickets: players get better winning odds and probabilities;

b) 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. So more gamblers will come for next round (bigger pots). P.s.: House's Tickets never add funds to jackpot, they are worthless, their only remaining purpose is to roll over the current pot to next round's jackpot. House does not profit from jackpot when its tickets are chosen;

c) Jackpot rolls over: raffle creators (gamblers) might set series ("championships"?) of raffles so when one game ends a % of that jackpot from last round rolls over to 1st round of next game;

d) Additional funds: an option to add manually some coins to 1st round jackpot would be interesting too (1st round starts +EV for all gamblers).

And more:

* Always a Winner at the end of last round;

* Transparent and Cheat Proof (Provably Fair);

* Cryptographically Verifiable;

* etc.


Here goes some calculations/simulations from that conceptual idea:



Notes from that simulation:

* One game consists of 4 rounds and entry ticket price of .1 BTC;

* Payout - 85% of jackpot: to prevent someone from attempting to buy all the tickets;

* 15% roll over: to ensure that the next game starts with some value on pot;

* 4 rounds: 4th round without house tickets.

P.s. Winning/Losing Probabilities; EV (expected value); Variance and Standard Deviation => Gambler's perspective.

Advantages (HOUSE): by implementing that idea, the house gets some profits from rake (when there's some relevant scalability), some explosion of new visitors (potential gamblers and advertisers) and the 1st P2P +EV raffle game ever!

Advantages (Gamblers): +EV Games to play/gamble, bigger pots to win, profitable on the long run.

What do you think about it?

Would that possibly work?

Are there any flaws, issues or problems I did not figure out yet?

Collaborations are appreciated...
8  Other / Meta / Watchmember: a Watchlist for members only. on: August 26, 2013, 04:37:50 AM
Is there an automatic way to follow a member's activity (member's started threads or posts) on the forum?

If not, I guess that would be a great idea to implement: a "follow me" button/option so people could follow those members they like. Something like the watchlist feature but adapted to members (watchmember) only, instead of threads.

What do you guys think about it?
9  Economy / Service Discussion / ⛓LIST⛓ BitcoinTalk's Escrow Providers: Ranking & Blacklist ☠ Avoid Scammers ☠ on: August 18, 2013, 04:51:01 AM
Reasons for using Escrow Services (provided by Escrow Agents)

WHAT IT IS: People trading goods and services can add a tool in order to "increase" the trust on both sides: customers and vendors. That may be done by employing an escrow system for all transaction. That additional step gives both sides some garantees.

HOW IT IS: This means that when you make an order the coins are deducted from your wallet, moves into a temporary escrow account, then after the vendor sends the order, he confirms it was sent. When you receive the package, you confirm it being received and the vendor claims the coin.

WHAT IF: If for whatever reason you do not receive the package you can send the order into resolution, where you and the vendor can resolve the problem or should that not work, the escrow service will step in an resolve the issue. Keep in mind this system is to prevent fraud on both the end of the seller and the buyer.

SUMMARY: Escrow services will not grant you 100% scam proof, but it is definetly an additional security layer in order to avoid coin losses and fraudsters.

All parameters here are subject to change, this is a work in progress...

If you got an idea, share it with us!

This is not meant to be an exhaustive list, just an preview for clients/customers in order to avoid scammers.

We cannot guarantee any member's reliability neither that your coins will be 100% safe. Due diligence is still necessary, do yours!

Legend & Labels:

Rank: the member's position at the list;

Reason → General classification of escrow providers.

Member: member's ID.

Cryptocurrency: which coin the escrow provider works with.

Score: it is the following algorithm.

Code:
( 10 * sqrt(Trust) + 0.5 * sqrt(Activity) + 1 * sqrt(Merit) ) / ( 10 + 0.5 + 1 )

Reason → just trying to build our own kind of fair classification here.

P.S. Collaborations about a fairer algorithm in order to improve that task will be much appreciated.

Trust: the 1st number (left to right) the escrow provider got at bitcointalk.org Marketplace trust system;

Reason → "Web of trust" inside bitcointalk.org community.

P.s. escrow providers with overall negative ratings (1st number left to right) will not be accepted on the list (the same for those already tagged as "SCAMMER" by community staff).

Brand new members with "Newbie" and "Jr. Member" status won't be accepted on the list as well: go get some activity first!

Activity: the number shown at that indicator (under member's name/avatar). It shows how active (and for how long) that member is at bitcointalk.org community. Members without activity for more than 6 months will be delisted.

Merit: the number shown at that indicator (under member's name/avatar). It shows if that member posts good stuff at bitcointalk.org community.

Deal: Minimum→Maximum: minimum and maximum amount of coins allowed/accepted while using the escrow service (in BTC or USD).

Fees: cost for using the escrow service.

Sign.: Does the escrow provider work with PGP signed messages? And/Or does he or she sign messages from an already staked2 cryptocurrency's address?

Reason → Signed messages are additional security measures in order to grant the client some Confidentiality, Integrity and Non-repudiation.

If you wanna apply for this list, please post here (or send me PM with) the following info:

1) Which cryptocurrencies do you work with?

2) Minimum and Maximum amount of coins allowed/accepted while using your escrow service (in BTC or USD);

3) Your fees;

4) Do you work with PGP signed messages OR signed messages from an already staked2 cryptocurrency's address?

[1] "Score" for the Crypto Escrow Team (CET) is calculated by adding all "Activity" and "Trust" numbers from all its members and then dividing those sums by that same number of group members in order to get a more fair and real score.
