581  Bitcoin / Development & Technical Discussion / Re: Dead man's switch on: November 15, 2018, 07:37:35 PM

I don't know why you are insisting for there to be some live program running when there is such a simple solution already stated with timelocks. There is absolutely no need to create any new programs or servers for this.
Bitcoin was already designed from the beginning supporting these things.

Timelock value exist in every transaction, they are just set to 0 by default in most wallets.

To be honest you're right. I was writing a response to bob123 but after you wrote your post I abandonned because regardless if we can make it work, why not just broadcast one tx?

Make a timelocked transaction that spends his coins when he's a 100 years old, or a 120, some time that he obviously won't reach.

Broadcast it and that's it.. If he decides to spend his coins before that, then do it, otherwise, they'll be transferred to his friend.

But as a quick answer to you bob123 :

1. HeRetiK's solution also stores the timelocked transaction on a server.
2. You can easily change my solution from "press a button to send the tx", to "press a button occasionally before to prevent the tx from being sent from the server."

My solution also doesn't expose his private keys, or endanger his money, all of those are only known to him. The server holds 2 transactions to addresses he already owns.
582  Bitcoin / Development & Technical Discussion / Re: Dead man's switch on: November 15, 2018, 07:12:57 PM

That's not really redundant.

Your solution involves trust. OP could theoretically broadcast the transaction earlier (e.g. working together with the recipient).
This should definitely be considered.

Heretik's solution on the other hand doesn't involve any trust.
The owner of the coins is the only one who can initiate that transaction (by not creating a new one).

IMO that's the best solution for a dead mans switch (at least the best i can think of).

Yes I've been thinking about it for a while, you could do this with only one timelocked tx.

You craft the transaction that will spend the coins from his existing addresses, to address A.

You craft a timelocked transaction from the output that still doesn't exist inside address A, that spends these same coins to the addresses of his buddy. This timelocked tx can be for example when OP is a 100 years old.

Broadcast the second tx. And don't spend the original coins.

That's it. Now he only needs to create a "switch" to spend his coins to the address A whenever he dies. A button on his phone when he's on his deathbed, or something.

In case he's still alive, he also owns the private key to address A, so he can invalidate the timelocked tx by sending the coins back to himself it if fuck-ups happen.
583  Bitcoin / Development & Technical Discussion / Re: Dead man's switch on: November 15, 2018, 06:37:57 PM
I can think of a few ways to do this with a smart contract, but in bitcoin it's a bit harder.

I'm not sure about the implementation details, but I think the general logic would be as follows:

1) They sign a timelocked transaction using their private key, sending the coins to the target address but not redeemable until date x.
2) The timelocked transaction is stored on your server
3) Before date x arrives, they move their coins to a new address and sign another timelocked transaction using the private key of the new address.
4) Rinse and repeat until date x arrives when your server publishes the timelocked transaction to the network.

This way their private keys never touch the server, they can spent their coins however they like and the owner of the receiving address can't spend the coins until the dead man's switch has triggered.


This is basically the solution but it's kind of redundant.
A simpler one would be to just sign the tx that would spend all his coins right now. And store that transaction on a server. Write code in your favourite language that broadcasts the tx after Y amount of time just for an added layer of security. And open up a port on your server where the application can listen to.

If the application doesn't get pinged once every X months, weeks, whatever, then it calls the function, and after Y amount of time, the tx will be broadcasted.

So he has to ping the server every X interval, and if he somehow fucks up and forgets, he has Y more time to stop the application from broadcasting his coins.

Hell if you want I can probably set this up for you in node.js right now.

He is famous for manage spam free signature campaign.
A bounty campaign can't survive on this forum without spam, as long as only spam threads get most exposure.

It's true, all you need to do to see this is to keep the Bounties section open to see how much of a shitshow it is. I don't understand how people can have the time, effort or human resources to keep creating newbie accounts to bump their threads, but I figure if it's going to give them more visibility they believe it's worth it.

To OP, you can try taking different roads. If you have an ICO, announce it in the Altcoin ANN section, and maybe implement some sort of reward system to people who promote your ICO on your website. An example of this was Stellars when it just started. Everyone who logged in using their facebook account got a few free stellars.

Of course a few people might abuse it, but if you promote your project right you'll definitely get more organic traffic versus botted.

Lol this is an interesting post. Can you share more about how you pick these games? Do you just look for the highest odds on some unknown teams and bet on the one that has the worst odds of winning? But why are all these games so nichey though, would love to hear more on how you do this, you basically won 3 out of 4 bets
586  Economy / Gambling discussion / Re: Best gambling website to invest into? on: November 15, 2018, 07:17:26 AM


I'm personally invested in:

* bustabit (0.35BTC)
* bustadice (0.35BTC)
* YOLODice (0.3BTC)
* Crypto-Games.net (0.5BTC)

and I added one more site about 2 weeks ago:

* BetKing (0.1BTC)



The best choice imo is bustabit as they have the highest volume/turnover, so you should have the highest profits there. YOLODice is also a good option if you don't want to pay a dilution fee and want to have a high leverage. C-G is also good if you want really low variance.

That's neat! You should maybe make a quick spreadsheet and update it bi-weekly with how much profits you made. Might help you too move more funds into the website you make the most out of.

I did end up investing with bustabit indeed, 2% dilution fee is meh but I guess time will make that back soon. I'm not looking for a quick buck to be honest just somewhere I can place my funds for a few months and make some slow small dime.

I would say just-dice, they have been over 1% of winning for a long long time now and they have been getting a lot of wagers with good profits, they are still one of the most known ones thanks to owner doog (don't know if he is still the owner) and bringing cash for the investors.

Yeah I've used Just-dice in the past. Just when it rebooted with clams too, drove its price through the roof. But the coin died out now and I don't think it would be wise to invest in it.
587  Economy / Goods / Re: Company registration in Bulgaria or Delaware on: November 15, 2018, 04:43:57 AM

1. I can not claim a company, since the company registered on the name on clients, not the person registring it.
    So that means that the client has 100% ownership.
2. The pluses of a Bulgarian company in the EU is that you havee a very low corporate tax 10% corporate and 5% devidend tax, the same thing in Delaware you have no tax for Delaware company if your business is outside the US. Set up of bouth companys in from 2-5 days.
3. Banking account is apoun wish of a client, and priced separately.

At the end of the day the client gets the company on his name with all the documents to use it, with no our access to it.

The prices are following
Bulgarian company - 500 USD
Delaware company - 660 USD
Fee includes the shipping of the the documents and translation if needed.

If you need a company registred on a gypsy it a topic to talk about.

You can register a delaware corp for under my name, even if Im not a us citizen? And Ill pay taxes for it too? I mean I honestly cant see what your job is here.

If you can only register a corp for us citizens then why dont they do it themselves? If you can actuallh register a corp under any worldwide citizens name then I'd very much like to hear it.
588  Economy / Gambling discussion / Re: Best gambling website to invest into? on: November 15, 2018, 04:38:31 AM
Thanks for the suggestion everyone. I'd try them all honestly but my budget is too short for me to effectively compare profits from all of them effectively.

bustabit also started accepting bankroll investments since v2 launched back in January. However at 4,611 BTC the bankroll is already quite large so investing may or may not be worth it depending on your risk tolerance.

Isnt bigger bankroll lesser risk? I dont get what you mean.
589  Economy / Goods / Re: Company registration in Bulgaria or Delaware on: November 13, 2018, 10:36:39 PM
Lol, this ought to be interesting.

You're going to create these companies under your own name? I can't say I'm not interested but there are so many questions hanging that it's impossible for this to make sense. How can I trust you're not going to claim the company for yourself? Are you going to pay setup/tax fees? How exactly do you have access to making both a delaware corp, and bulgaria? Please post more extensive info about this.

Like, its obviously a scam, but you picked my interest because Ive never seen something like this before.

Thanks to both of you @HereTiK and @bob123.

Sorry I get what you mean now by 58 chars, I was thinking the wrong way.

I just thought there might be some specific way to branch the search out to get the desired goal in the end.

If you take my own address for example : 1KingZeeW97uLvngcUA3R6QJx18Fn78ddb

You're basically telling me that I need this many keys 2.207.984.167.552, -at least- to run through every possible combination of 7-letter words, and maybe land into the pattern I want.

While I do believe now that there probably isn't a better way, this just looks like a very awkward Hoyle's fallacy to me...
592  Economy / Gambling discussion / Re: Best gambling website to invest into? on: November 13, 2018, 01:23:31 PM

Yeah, they let people to invest and your ex manager, Luptin has invested here too, a lot of people who invested here are satisfied. As far as I know another good option of investment is Yolodice.
Btw after seeing leaderboard, maybe it doesn't worth to invest in bustadice -> https://bustadice.com/leaderboard
On another hand, there is no good option, for me it doesn't worth to invest here, better to buy GPUs and mine.

I mean I'm sure if the other websites had leaderboards we'd see some big whales too. I saw it before I invested but it's not accurate to judge, I'm sure there's a negative leaderboard they don't show. Smiley

Mining is dead in my opinion unless you have a very big capital to invest with. One 800$ card will net you 1$ per day assuming you don't pay electricity bills. I'm sure profits scale pretty well if you're going to invest into rigs of multiple cards at once, but not everyone can afford that. So because I don't usually like to gamble on dice and fully randomised things, I figured investing was a nice middle ground for the long term.
593  Bitcoin / Development & Technical Discussion / Re: How does vanitygen find a pattern? on: November 13, 2018, 12:52:33 PM
@bob123 Thanks for the answer! A few things I have to question..

In fact, it is randomly generating private keys, trying to find a private key which results in an address with the desired prefix.

The estimated time can be calculated using stochastic. Note that this time is always an average. There is never a guarantee that you'll find your desired private key in the estimated time.
It might take 1 second or 10 years.

Are you sure? I thought it showed worst case scenario time? I'm talking about samr7's vanitygen. I know it might take a lot less if you get lucky, but it shouldn't go above that time. It calculates the time to reach 100% probability of getting a specific pattern.

Since the hashing function is generating a pseudo-random output, you can calculate how much private keys needs to be generated to find an address with a specific prefix (on average!).

To be more precise:
There are 58 different characters inside an address.

You mean 34? The pattern is inside the address, not the private key! I'm going to edit your maths in the next quote.

To find a private key which results in an address with the prefix of 1 chosen character, you'll need to calculate 17(= 34 / 2) private keys to have a 50% probability.
To get an address with a prefix of 2 chosen chars, you'll need to calculate 578 (= 34 * 34 / 2) private keys ( to have a 50 % chance of finding a suitable private key).

The formula for X chosen chars (with a 50% probability) is:
Code:
Priv_Keys_to_be_calculated = 34^X / 2

See this part I don't understand. How are you calculating all this? The pattern is in the output, not the input.

You could generate a private key, get an output of 1SomeBTCAddressxxxxxxxxxxxxx, generating just the neighbor of that key, will give you a completely different output.

See what I dont understand is how does calculating n number of private keys, gets you closer to generating your wanted private key. How does the process of elimination go? If it were truly random then we'd just be blindly generating random keys constantly.

Can someone please explain the rules:

- Entrants are awarded one point for a correct result, and three points for the correct score.

If the maximum prize is 24 points: 0.0120 BTC, then 24 / 3 = 8 correct scores to be predicted. How can these be done, when there is only 6 game pair ?


You get 6 extra points for backing your picks with a bet of over 5$ on CloudBet.

So 18 points for free picks + just 1 backed bet will max out your point winnings if you get eveything right.

Quote from their post :


- ‘Back Your Bet’ Bonus! Post your predictions along with a Cloudbet Bet ID to confirm you have placed a multiple (accumulator) bet on your chosen predictions, and you’ll receive a bonus 6 points added to your weekly score!

595  Bitcoin / Development & Technical Discussion / How does vanitygen find a pattern? on: November 13, 2018, 10:44:43 AM
Can anyone explain to me the concept or link me some source that explains how can vanitygen find a pattern in an unreversible hash?

It's clearly following some search pattern that isn't just trying out random private keys and hoping to find the desired pattern. People can let it run for weeks to find a 8-char pattern for example. And it'll slowly display the probability percentage until it finds one. I'd like to know the maths behind that if anyone can give me a clue, cheers.
596  Economy / Gambling discussion / Re: Best gambling website to invest into? on: November 13, 2018, 10:42:40 AM
Preferably a website that has been around for at least one year, and proven itself as a profitable source on the long term. No one likes scam exits. Cheers!
Crypto-games.net
Bitvest.io
These two has been running for more than a year so your money is safe for investing on each bankrolls.

I was in the crypto-games sig campaign in the past, I know they're trustworthy. I didn't know they let people invest in their bankroll though!

I would suggest yolodice.com and bustadice.com

here are the current investor stats

Yolodice
285.74810445BTC
3898.65546287LTC
1063.96312825ETH
−100154.21610517DOGE

they just recently added DOGE on their site and someone won around 1.5m doge lately so it is negative now

Bustadice

702.77816871BTC

Thanks, I decided to invest in bustadice just yesterday and the profits went from 720btc to 696. My luck still as shitty as I remember I guess.

Anyone has any recommendation on some good, big gambling websites that allow investments into the website's balance? Feel free to let me know your experience, and why you prefer any specific website.

598  Alternate cryptocurrencies / Altcoin Discussion / Re: Proof Of Transaction "kills POW and POS" on: November 12, 2018, 09:43:58 PM
This topic belongs to the altcoins section. Or rather, the shitcoins section. This "kil" title is just a clickbait. The reality is that this is another token ( ERC-20) with a paper without major technical specifications. And an account that serves only to shill creating various topics about this project that no one knows or discusses about.

In general the word "kill" is always going to be clickbait.

The one and biggest example to cite against that is Ethereum. It comes with a MASSIVE boost to functionality compared to bitcoin. If bitcoin is a decentralized transaction ledger, Ethereum is like a decentralized master computer where a "transaction ledger" can be a tiny small application of its full potential.

AND YET, look at bitcoin price going up. Regardless of whatever new altcoins come up with, they will never override existing coins. Purely because of the sheer amount of money being moved around. Its ironic how this used to be said about banks, but can now be said about both btc and eth, "They're too big to fail."
599  Economy / Games and rounds / Re: ⚽🏆 Cloudbet's Super 6 Soccer Predictor Competition - Free Entry - Win BTC! 🏆⚽ on: November 12, 2018, 06:04:21 PM
A good suggestion because many users have this problem so they need to post this if some one is not claiming then its going to be for next person in list hopefully Cloudbet will no mind about this.

Lol that's a bit selfish, they won fair and square, no one would want to let go of their prize simply because of EU regulations.

Maybe CloudBet can spin the slots themselves and send whatever the outcome is to the winners? But that might be a bit unfair as it's not provable.
But then again, since people in the UK might legally not be able to use their website, I don't think CloudBet would want to run any risks by letting them gamble. So it has to be some sort of reward that doesn't involve them gambling I guess.

The best of both worlds in my opinion would be letting people choose to either pick a very small flat weekly reward, or take the free spins if they're feeling risky.

Wow, that was a pretty high scoring week!

Congrats to our 6 winners this week: DeathAngel, exsith, Kriptopsina, LFC_Bitcoin, maximhkn, and pa1nxgod! I'll be in touch soon via DM to discuss prize delivery.

Two in particular deserve a special mention, as DeathAngel and exsith both managed to hit 3 exact scores and one correct result! Those 10 points have propelled them both up the leaderboard after relatively slow starts, giving hope to all of us mere mortals that there's still time to climb!  Wink

I'll get this week's games up soon, I stupidly didn't account for international break so I'm checking to see what games are available this weekend!

Thanks,

Ronnie @ Cloudbet

Great job to DeathAngel indeed, he got Newcastle vs Bournemouth which was arguably the hardest game to decide. I missed 2 points by a hair on the City vs Utd game, but oh well, hopefully I'll have better luck the further weeks.

Looking forward for next week's games! There's both European and African Cup of Nations qualifications.
