401  Bitcoin / Development & Technical Discussion / Re: Understanding The Satoshi Codebase (Series) PART 1 - on: July 01, 2019, 10:36:03 AM
There is no code that limits the subsidy... it is mathematically decided.

Since the amount rewarded by Bitcoin is /2 every 210000 blocks (about 4 years), this reward will reach zero 34 years after the genesis approximately
You can refer to this table in order to have a better idea about how it happens.

https://en.bitcoin.it/wiki/Controlled_supply

So you will not find something like

Code:
if (height>21000000) then reward=0

Also the number of coins mined is not 21 Millions, it is an approximation. The real number is 20999999.97690000
But of course it is more convenient to round it to 21 Millions.

Fantastic work. Could you please point me out to the part that defines total supply to be 21m?

403  Alternate cryptocurrencies / Altcoin Discussion / Re: How start to developing with Solidity on: July 01, 2019, 08:04:01 AM
Solidity is a very easy to learn language. I advise using Remix the online version for quick prototyping.

https://remix.ethereum.org/#optimize=false&evmVersion=null

You can click on one example and modify it, and then start doing your smart contract.

Here is a smart contract in Solidity that I have made 2 years ago... it is a good starting point, it has all the features needed including a solution to start and stop ICO/Fundrasing.

404  Alternate cryptocurrencies / Altcoin Discussion / Re: An explaiation of my recent work——for the PoAS design paper on: July 01, 2019, 05:50:40 AM
I read your paper and I congratulate you on your efforts.

I have some objections though.

1) the gatherer are accumulating stakes but based on what? a coin address? IP address? How these cannot be hacked or lost in case of changing wallet for example.
2) I do not agree that POW is useless. Your solution do not imply any specific efforts from the miners, they are mining nothing, they are only generating blocks... there is no difficulty and no cost of it, so why are they still useful? Block could be mined by anyone running a full node, like, the gatherers or the users? Voting is not "time or power consuming", it costs nothing. So rewards are for doing what?
3) The accumulating stakes are doing basically what a stratum pool is doing, you embed the functionalities into the blockchain and into the wallet.

You could obtain the same result by

1) controlling who can own a pool from the wallet. That means, the wallet would have hard coded a pool hash and would not accept any hashes from another pool. See it like a franchise.
2) controlling the difficulty by limiting the hashrate from these pool, which would force miners to limit their work and share more evenly. Competition between miners is not a good thing, it drives the hashrate too high and penalize the small miners.
3) controlling the mining software so that the hashrate information are sent and not faked. The pools would not accept a mining software that does not send information about the hashrate, and specs of the computer that is mining.

This way you could almost achieve what you are looking for, with Bitcoin or a fork of Bitcoin, and without changing the protocol or the blockchain mechanism.

Of course the mining would not be decentralized, but controlled by the developers who btw would make a % of this mining that would pay for the development and maintenance.


405  Economy / Exchanges / Re: This transaction is a fraud on: July 01, 2019, 05:32:55 AM
Controlling the Yahoo account is not enough...
The hackers must have had access to his computer and used the pre-saved password to receive the email from Kraken and pass the security.
That mean he has a trojan. He has to clean up his computer asap.

They hide these trojan in pirated stuff, and when you install the crack, you open a backdoor, from there they can go on your computer, and scan silently for a wallet.dat
If they find them, they download them. If you haven't encrypted your wallet, you lost your coins.

Then they will try to get your coins from the exchanges by using your saved password in your browser.

Never use an exchange that is using emails as 2FA, use only the ones who are using Google Authenticator. The hackers cannot have simultaneously access to your phone and your computer.


somebody hacked my yahoo account and kraken credentials
an unauthorized withdrawal was acceptad
i don't know how to recover my money but that's all!!!

That sucks. Sorry for your loss. Undecided

You should stop using Yahoo immediately. Billions of Yahoo accounts have been compromised in multiple hacks. I recommend a more secure email provider like Gmail.

Like others have said, the money is gone. At this point, you need to worry about securing your computer and accounts. I would follow TheWolf666's instructions regarding cleaning or formatting your PC. I would back up anything important and then format myself. Change your passwords, switch to a more secure email provider, and start using 2FA on your exchange accounts.
406  Bitcoin / Development & Technical Discussion / Re: Is Lightning network suitable for Altcoin blockchain based on Bitcoin core? on: June 30, 2019, 06:59:16 PM
I will try with Electron or Zap and post the result here. The complicated part is to compile and install the server on several nodes.
I guess the only change apart from the name and logo is the RPC port since Lightning is all working through RPC I think.


You should be able to get Lightning Network running easily on every Bitcoin fork which supports SegWit. If you make a fork of Bitcoin Core 0.18 then there shouldn't be any problems.
407  Economy / Exchanges / Re: This transaction is a fraud on: June 30, 2019, 06:21:35 PM
I feel sorry for you.

I got the same problem before. You probably clicked on something that installed a backdoor on your computer.
This is what I suggest.

1- stop internet... the hackers are taking control of your computer remotely and are intercepting your password.
2- backup any wallet you may have on an USB key.
3a- either you install Spyhunter (that is the most honest anti-trojan in my opinion, do not trust Malware Byte, they do not flag the NSA tools, and the hackers are using the same tools since they have been leaked by Wikileak)
3b- or you re-install your computer completely.
4- setup 2FA (using Google authenticator) with all your trading account. Do not deal with exchanges which does not support 2FA security.
5- if you save your passwords in a text file, change all your password and never write them in full. For example a password like WE$90899Balty should be WE$*****B**ty so that you can memorize without saving the full password.

Your transaction cannot be reversed, but you can avoid more problems by acting fast and avoid this to happen again.

 Shocked
408  Bitcoin / Development & Technical Discussion / Is Lightning network suitable for Altcoin blockchain based on Bitcoin core? on: June 30, 2019, 05:19:53 PM
I was wondering if there was some sort of gateway so that Alcoins could use the lightning network technology.
Since Litecoin implemented it, if you have an altcoin that is a fork of Bitcoin 0.18, all the functionalities should be there?

410  Bitcoin / Development & Technical Discussion / Re: Is PoW Outdated? What are the Essential Advantages of PoW Consensus? on: June 30, 2019, 03:59:22 PM
Sorry to disagree with most of the answers here, but I think that POW is the only relevant answer to the problem of strengthening the blockchain and make it impossible to be reversed, without having a central authority that is controlling the network.

Without mining and all this work generated by the miners, you only need the private key to hack a blockchain. Most coins that are not mined are centralized (Ripple, or Libra). These people want to have a way to reverse the transactions, either because they are big corporations who do not want to have a problem with a government or because they just want to be acting like banks.

Satoshi Nakamoto nailed it and without being peer to peer, or without POW, Bitcoin would never take off. There were many attempts to make cryptocurrencies that failed at this time.

Now, because most people are playing with crypto like in a casino, the relevance of all this work is starting to be forgotten. Scams, and unsafe crypto are popping up from everywhere and nobody seems to care if they are safe or not, if they are centralized or not.

Without POW, a blockchain is not safe. And who cares about the electricity? All our cities are using countless of bulbs all night and nobody complains about the waste. The electric consumption of the miners is just another propaganda against the crypto, built by the fiat resistance.

Playing video games is also costing a lot of electric. All these geeks playing all day on their computers, is this useful?  Grin Grin Grin Save the planet: stop playing games!

What exchange would you suggest based on your experience?

Try HitBTC, I have an account there. They are pretty cool and the technology is good. There is a French chat too, some French investors.

They have very high commissions for the conclusion that it is not good. But they have enough liquidity that even considering all the disadvantages is a huge plus. I will continue to monitor this project.

At the beginning of Bitcoin everyone was using his own name. Everyone. Some answers are simple. If the guy disappeared that means that he had a reason. The fact he goes at Bitcoin 2019, means something.
Maybe this Craig impostor has pushed the ball too far and got him upset enough to kick into it.

416  Bitcoin / Development & Technical Discussion / Re: Questions about syncing and how to calculate how big the blockchain data is? on: June 28, 2019, 08:47:52 PM
1- if you just look for an estimate you can just multiply the average size of a block by the number of blocks?
2- if the blockchain is corrupted, you will get an error message and a suggestion about what you can do to repair it, but in most cases, the sync will continue.

Note: you can also "prune" the blockchain, that mean store only a limited number of blocks. Search for "pruning" options.

This might be a turning point in the Bitcoin mystery... is there any Japanese here that could translate the Japanese part? He is talking about his life and there are sure some really interesting information.

You should have a look, it might be a good choice.



Don't be thrown to trash be recycled  Tongue

Well, I am looking too much forward maybe, but this tech, because we are on this forum, is the forwarding thing. I was working with PHP for a long time and I agree that 80% is PHP, from which 79% is Wordpress probably, but that does not prove it is not obsolete and that same percentage will be next year. I can bet it will go half in next 3-5 years. Because of all that is "the old www" which also becomes obsolete. I see future www as something for which PHP is not capable to do.

For most "regular" people Google is "the internet", from one hand and from another you need to be seen if you want to sell something, product or story, so by my opinion if you want something to work in that manner than do exactly what "the master" said.

Corporations are greedy, but if you look the wider picture of what is happening now in this field of IT is that many corporations made things open and even hired some important people or start to fund some independent organization/community.

When I was introduced to Go first thing which I found important was exactly that, the largest company put together in team Rob Pike, Ken Thompson and Robert Griesemer (who are the true legends, each of them deserve many credits for this what we have today, from UTF to Go) to design language for Google's needs, which means language for today's large network systems, etc.

Thing is I am not a programmer, I am an artist who is dealing with technology and my goal is not to do what someone wants just to be paid.

As soon as I make accessible online I will be happy to show you my work, for now, you can take a look at the code https://git.parallelcoin.io/marcetin/explorer it's easy to read. End thing will be making that standalone blockchain explorer application in which user will be able to put addresses of nodes to be read.

Thank you Smiley
420  Bitcoin / Bitcoin Discussion / Re: How to know who is Satoshi Nakamoto or the Bitcoin Cinderella shoe. on: June 28, 2019, 02:29:53 PM
 Huh Huh Huh

Ok the time stamps are
Genesis #0: 2009-01-09 02:54:25
Transaction #394: 2009-01-14 01:52:50

So it took 5 days to mine this transaction that was sent to Hal Finney. (2x more time that it normally should). Who was mining 5 days after the genesis at this date 2009-01-14 01:52:50 and sent 2000 BTC to Hall in 2011?

That's my point.

Double check what I am saying, check the transactions, check the blocks...
What I am saying is true. Satoshi sent these 2000 BTC to Hal in 2011. He has the wallet with the transactions, and all the unspent transactions. That's the Cinderella shoe.

Think about it. The block #394 was mined 3,940 minutes after the genesis. That's only 65.67 hours after the genesis. Who was mining BTC at this time?. And do not tell me that Hal sent 2000 BTC to himself!

when you start a topic like this, you need to get into the habit of checking things you say so that they are factual. otherwise everything else will look like your own guesswork.
in this case you are simply multiplying number of blocks with number 10 but you are missing the fact that finding blocks is a luck based thing and also with difficulty 1 it can't go lower than that so sometimes it takes longer to find a block.
so the time (if you actually check the blocks) is >5 days or >120 hours
