Blockchain is the process where you are storing the information or the commonly use is the transactions every time we made and by this block it will encrypt this and make a another blockchain to make it more secured.

Some of the people are using the blockchain not only in cryptocurrency also with the use into the world of businesses too

Examples
Storing of file system on schools
Storage of records and business
Payment transaction

Important Point: It's not the block-to-block reference but the difficulty of adding block and distribution of ledger are what which make blockchain secured. You can try saving school files or business records in blockchain but if your blockchain is not distributed enough and adding block is easy, it is no different from traditional database and hacker can change data of any block and re-generate hashes of the subsequent blocks in no time.

Sometimes, blockchain is hyped more than it is capable of.

Pot is at 0.35564980 with 0.1 for first place with many more prizes to be won and a free Watford shirt so it's a steal either way.

So is it sure that we gonna get Watford shirt? No possibility of Southampton new shirts?
443  Other / Beginners & Help / Re: Question about transactions on: September 16, 2020, 07:20:49 PM
Hi, I'm a beginner to Bitcoin. I made a lot of search, but there are some things about how transactions work that still make me desist from getting into the business.
The answers I found to my doubts are ambiguous and I hope someone can help me to clear them.
I created a wallet (I tried Bitcoin Core and Electrum). If I've well understood, when I want to receive a payment, I have to create a new public address for every transaction. So, if I use a new address, nobody should be able to associate all the payments received to a single wallet. If I want to send Bitcoins, I need the public address of the receiver.

Any transaction is written in the Blockchain, and there are some sites that, for a given public address, can show several transactions associated to it, both for sent and received Bitcoins.
This is how it is explained for example here:
https://support.coincorner.com/hc/en-us/articles/360010531460-Understanding-a-Bitcoin-transaction
But how is this possible, if for every payment I receive I use a new public address? It shouldn't be possible to associate all the public addresses to a single wallet.

If you are just receiving bitcoins on new address every time and haven't spent any of the output then it is impossible to link your public addresses with each other. You will only see single receiving transaction if you search the specific bitcoin address on 'Block Explorer'. However, if you have sent money from the wallet then it is possible to link addresses. This is how:

Suppose you received 0.005 BTC on your bitcoin address A and 0.002 BTC on your bitcoin address B. Now you sent a transaction of 0.006 BTC to another address X. To create this transaction, your wallet will use both unspent outputs (UTXOs) as the input like this

Inputs                                                 Outputs

Address A 0.005 BTC        >>>            Address X 0.006 BTC
Address B 0.002 BTC        >>>            Change Address 0.001 BTC

There are some services which will create link between addresses through this method and will show you all linked addresses to the specific wallet.
 


Moreover, I found this page:
https://en.bitcoin.it/wiki/From_address
in which it says there's no "from address" from which Bitcoins are sent.
By the way, this page in contradicted by this page in the same wiki:
https://en.bitcoin.it/wiki/Wallet
Read where it says: "transactions done from/to your addresses".

Transactions are not done from/to addresses. Transactions are done via scripts and hashes. You create an output and lock it with a locking script. For example, if I say I am sending 0.02 BTC to Address 16Rv1veEeGncvoBEWYCjtp2ViSee1aRtrj what I am actually doing is this:

I am locking 0.02 BTC with this hash - 16Rv1veEeGncvoBEWYCjtp2ViSee1aRtrj and putting a condition that who ever can produce a valid signature using public key such that hash of the public key is equal to 16Rv1veEeGncvoBEWYCjtp2ViSee1aRtrj can spend these 0.02 BTC.

P2SH addresses i.e. addresses starting with '3' work little differently from what I just said. If you send 0.02 BTC to say, 3G8uPe3XKGhyQ2HGZfrmT7yJSxeQ6kJHK4, you are actually locking 0.02 BTC to the script whose hash is 3G8uPe3XKGhyQ2HGZfrmT7yJSxeQ6kJHK4. Now to spend these 0.02 BTC, you have to provide valid redeem script such that hashing that script will produce hash equal to 3G8uPe3XKGhyQ2HGZfrmT7yJSxeQ6kJHK4 and another script to unlock redeem script.

More doubts? Keep them coming.

Damn! It was a nice tourney. Still two left, I am rooting for Obaming, he is having a good run after coming to the final table but Steamtyme is one of the finest regular and got upper edge to win this one.

I had a long spell of lead but played couple of bad hands and lost big stack. That 44 vs Pitkin's A8 was mistake. I should have folded on flop. Nevertheless, 4th position is fine too but missed ITM spot by 1 position. Sad But someone has to be 4th, be it me this time. Cheesy
445  Other / Archival / Re: Bitcoin’s Hash Rate Reaches New ATH on: September 13, 2020, 03:24:30 PM
In light of these two considerations, i.e. the imminent halving and the price drop, the new Bitcoin hashrate’s ATH is even more surprising, despite being the result of an increase that has been going on for over a year now.  In this regard, there are those who point out that this could mean a more lively interest than ever in the technology behind Bitcoin, and that the network is now growing thanks to the strength of its community and no longer largely thanks to speculation.

Short-term price movements seem to have no particular impact on the hashrate, perhaps because the miners themselves are not interested in it, focusing more instead on long-term movements.

Whenever someone is planning to do mining for a considerable period (say 1-5 years), considering expected average price over the period would be better indicator of potential profits rather than the current price. I was interested in setting-up mining instruments last month so I calculated the potential profits. However, as per my calculation,
The average expected price over the mining period = $14,000 - $16,000
My break-even bitcoin price (price at which mining rewards are equal to mining cost) = $23,000

Hence, I rejected the idea. But the case is not same for every miner. If a miner is able to bring down his break-even price below the expected price over mining period, he will definitely mine even if current price is lower than the break-even price (provided he is ready to take some risk).



So, is mining proftiable now? New asics becoming outdated so fast

That's very subjective question. It maybe profitable for you but not for me at the same time. You need to calculate the fiat price at which your mining rewards will supersede your mining cost (since cost is mostly spent in fiat currency). Then compare the fiat price you calculated with the expected bitcoin price. If you expect bitcoin price to go above the calculated price then mining is profitable else not!

I have lots of expectation from Leeds United this season and I am rooting for them to finish in first half of the table. But first clash against reigning champion, that would be over-enthusiasm if I pick Leeds over Liverpool tonight. So I am going with 2-1 in favor of Liverpool but I really want Leeds to win this one! Anyone rooting for Leeds for tonight game?

As I understand it, the end of the week will take place on 15 September Tuesday 23:59 UTC. Until that time, I will need to write 25 quality posts. Hopefully 6-7 posts or topics per day will not be considered spam.  Smiley

Minimum post limit is 10. So if writing 6-7 posts everyday is not your natural writing habit, I would suggest you to not aim for 25 posts  for this week since only 4 days are left. However, if you write 6-7 posts everyday normally, I don't see any problem why would it be considered as spam because your posts will still be uniformly distributed.
448  Local / India / Re: What are best practices when trading P2P? on: September 11, 2020, 04:42:01 PM
I know that it is going to be suggested to not trade P2P at all and use exchanges which send/receive funds themselves. But P2P is always going to exist. Even when Bitcoin was kind of banned WazirX did allow P2P trades.

Therefore, I ask the expert traders to kindly share their expertise on how to go about doing P2P trades safely. So others do not get into trouble as the guy in the above mentioned thread did.

Thanks!

You are right, no need to enter into P2P hassle when there is a possibility of selling coins on Exchange and get money to your Bank Account easily from Exchange's bank account. It will help you in two ways - first you are always getting clean money and second it will help you in income tax filing because all you need to do is show all transactions coming from Exchange as earnings.

But in the case, situation like past re-appear and normal exchange operations are disrupted again (although highly unlikely), I will suggest you to make sure about two things:
1. Use P2P platform which has provision of verifying trader's bank account before allowing to trade.
2. Use P2P platform which only allows trader to deposit and withdraw to single bank account (the one verified by the Exchange).

For more security or if you trade high amounts, use P2P Exchanges which have separate rating system. For example, on WazirX you have option to pick trusted buyers/sellers using XID. When you place orders under such system, platform makes sure that only trusted traders buy or sell from you.

I would have taken some of those project really serious if they are not named after food names, I don't understand why some people feel that the community is going to take them serious, we all know how it is going to end for most of these project, they are just riding on the DEFI hype and when the hype goes down the project start failing

There is nothing wrong in naming projects after food items. All Android versions are named after sweet food items/desserts. Most of the testing suites are named after food items like Mocha and Ganache. Keeping everything aside, the biggest tech company is named after a fruit!

Name is hardly a problem. But problem with Sushi was that it was clear looking scam but still people invested. Anonymous founder, un-audited smart contract, copy code from Uniswap, extra ponzi type structure by providing additional LP tokens in addition to what Uniswap is providing. I still can't believe how Binance listed this coin? Binance listing stimulated newbie investors to unintentionally throw money in Sushi. I am losing faith in these centralized exchanges after all, they all are just big greedy douchebags. Listing shitcoins for their own benefit.

We are investigating the case on our side as we have not changed anything in the implementation since the initial integration. All our games results are still verifiable.

Our development team is on it and we'll get back to you and CGF as soon as we are sure that everything is fine.

It is good to see that you are actually taking care of the issue. But you should at least give a little update rather than strangling the issue until action has been taken. Looking forward to your reply to CGF and see what their stand is on the issue.



You are genius - told you that before, haven't I? Wink Good to see you helping me! And the community as a whole of course... Wink As a side note - since OneHash and Cyberdice belong together, no issues with Cyberdice?

Yes, you are right. CyberDice has the same issue too. I told that to CGF as well.
451  Economy / Gambling / Re: OneHash || Mutual Sports Betting & Casino || No Registration or KYC on: September 09, 2020, 01:25:04 PM
Important Issue and Advise

I found an issue in the provably fair implementation of OneHash couple of weeks ago and reported that to Crypto Gambling Foundation (CGF) since OneHash is a part of CGF verified operator's network. I got a reply from CGF that implementation was correct when they verified and added OneHash to the network which means they only changed the implementation recently. So, they wrote a mail to OneHash citing the reasons why they changed the provably fair implementation making it less fair! However, it's been two weeks and they didn't hear anything back from OneHash. So finally, they decided to remove OneHash from their verified operators network and informed me about the same. You will no longer see OneHash among the 'Verified Operators' on CGF:



So, if you play casino games on OneHash which claim to be Provably Fair, I would advice not to until OneHash clears the air about the issue. There are chances that OneHash is manipulating the results of the casino games!

Self tested:-
(1) WazirX
Issue for INR depositing because of Current Account manual money sending issues.. and withdraw fee also.

Can you explain in more details what issue are you pointing out here about WazirX? As far as I know, deposits are credited almost instantly if you send INR to WazirX's Current Account from the bank account you have verified with WazirX.

Also, deposit fee is just ₹5.9 and withdrawal fees are ₹10 (IMPS) and ₹5 (NEFT) which I consider negligible. Not a big issue for me.

Converting it in little-endian, we have:
0000000000000000000910c8873b8d4c6c467c5167d77af6afd6416f67021881 which will become block hash of the block.
...

Actually, you are converting it to big-endian.

"Big-endian" and "little-endian" describe the order of the digits (bytes to be more specific). Big-endian means that the high-order digits are followed by the low-order digits.

For example, we write one hundred twenty-three as 123, which is big-endian because the hundreds digit is first. That number written as little-endian is 321.


Ah, you're right! It's just a typo. Thanks for pointing that out.

Since everything is converted into little-endian before hashing so the result generated will also be in little-endian. However, it needed to be converted into big-endian to solve our purpose i.e. finding hexadecimal value lower than the target.

At last air is clear! Messi will remain in Barcelona. He spit out lots of words on club condition, President and even Koeman's project. He clearly said that he doesn't believe what Koeman is trying to do in the squad. Considering all the factors, I think it will be another disaster year for FCB but being long time supporter of the club, I will stand with the club for yet another year. Let's hope for the best.

I was waiting for the above news to clear before sending the pool entry fees. As it is now clear, consider me in and I will send the fees soon.

This is literally the way to go and beyond, they have done an incredible job. I mean they didn't give us any reason not to believe them, but the simple check would be to see if @webtricks actually got the money and to see if it is really fixed which should be easy to check.

I confirm that I received the reward. Also the issue on the site is fixed which I already confirmed yesterday. Everything is green. You guys can go and roll dice on FJ without hesitation. Wink
458  Economy / Gambling / Re: ★ BTCGOSU ★ Your Trusted Guide to the Best Bitcoin Casinos ★ on: September 03, 2020, 01:46:43 PM
Just released a guide to provably fair technology - if anyone here is nerdy enough, check it out! Cool https://www.btcgosu.com/provably-fair/

Not sure if I nerdy enough Smiley, but I checked it out with pleasure. It's one of the best articles on Provably Fair System I've ever read.

Only I think the section "Provably Fair System and Advantages" shouldn't start with words about Blockchain revolution, like this

But with the revolution of Blockchain in the early years of this decade, online gambling has completely transformed! Blockchain opened new doors of innovation which were earlier unvisited by the coders. Hence, soon enough Casinos had come up with a new system of fairness, popularly known as ‘Provably Fair System’.

because Blockchain, although can be used in Provably fair algorithm, is not a necessary element of it, especially when it's not a multiplayer game. CMIIW, I'm not that tech-savvy, tbh. Smiley

But still, I'll say it again. It's a great article which I enjoyed reading very much. Thank you!

You are right about the fact that 'standard provably fair system' and 'blockchain technology' hardly have anything in common. However, it was only due to the rise of Bitcoin and Blockchain Technology that 'SHA-256 algorithm' came into limelight. Bitcoin fascinated people by showing the different use case of 'one-way hashing functions'. Hence, people soon enough found a way to use 'one-way hashing function' in such a way which could solve the 'trust' factor which players had to put on casino.

That's why I used this line: Blockchain opened new doors of innovation which were earlier unvisited by the coders.

I no where mentioned in the article that provably fair system itself is based on blockchain technology. I hope it's clear now. Smiley

Final announcement regarding the new Dice Game:

We would like to thank you for your feedback regarding the concerns of the New Dice game being entirely Provably Fair or not. Specials credits to @webtricks for taking his time to go deep into analysis and putting out thoughts out here for the community. Since the day one of us reporting the issue, our technical department has been in touch with the board members of the Orbital Gaming (official provider of the game) to find out if there was any type of bug, that the team has missed while implementing the new version of the game onto the FJ’s platform.

Despite the fact of us not taking any advantage of possibly manipulating the results. We as a trusted casino among reputable members of the crypto gambling were obliged to take the thoughts of the users who prefer playing here at FortuneJack into consideration. To meet the current standards of the Provably Fair system (that’s been ever-changing since it’s foundation), our team has decided to report concern of @webtricks as a fairness bug.

According to the past bug bounty campaign, hosted during the period of July 1 to July 10, finding the fairness issue had the bounty of 1 BTC. To be thoroughly equal to the past reporters, we had to come up with the reasonable amount to adequately meet the expectations of the user. Correspondingly, he will be given the reward of 0.5 BTC (Bitcoin) for outlining the issue publicly, suggesting the way of us fixing it and being an honest member of the community in general.

As for now, the bug that we’ve been talking about previously is completely fixed and the update itself is already live on FortuneJack’s website. Feel free to give it a check and continue playing a new version of the Dice without having any type of hesitation, whatsoever.
.....
.....

I just checked the updated version of 'Dice' game and it's perfect. Player is given the SHA-256 hash of next server seed before changing the client seed. That's what I asked for and it now assures that FJ cannot change the result after player changed the client seed. A perfect decentralized trust system!

I really appreciate FJ for escalating the issue and solving it within the time frame asked. That's a difference between a reputable casino and others.

Thanks for the reward, looking forward to receive it.
