The Bitcoin wallet cannot hold more than 22 Billions. After that it goes in negative.
That's my experience when doing an altcoin.
Of course for Bitcoin this will never happen, but when doing an altcoin this has to be taken in account.
Transaction limits are 22,518,000 coins due to the 52 bits representation internally. Thanks to Cryddit for this precious answer (in pv)

Thanks for the answer, at least 1 answer to that post lol, I was waiting desperately that some Legendary gurus come to help, but no luck! Actually, Bitcoin Core 0.17.0.1 (latest at the time I am writing) has a lot of security checks, that are basically blocking any altcoin to be developed from their source code without removing them. I understand that Bitcoin needs to be secured, but adding a "if (nheight>somevalue) {" when they are adding these security checks would help newbies to get into this code in a shorter time. Some would say, if you cannot find out, then you are not good enough to maintain a coin, I got these kind of answers from people who are supposed to have a hi-IQ in these forums. Amazing. So now the way to overcome the fact that there is no internal mining code (since version 0.14) is to use a pool and stratum. I have fixed my problem by installing Yiimp (there are install scripts for each version of Ubuntu, latest is here: https://github.com/xavatar/yiimp_install_scrypt_ubuntu18.04 ) Once you have installed Yiimp, you can use ccminer to premine or just run the blockchain because without mining the blockchain is dead. You need to comment all the timing/headers/Tips security tests otherwise your nodes will ban your mining wallet, or just comment the ban system as it is not working for new coins...and that's it. No documentation about these kind of issues in any "make your own altcoin in 10 min" posts of course. All these tutorials are deprecated for Bitcoin 0.17.x |

I was bored one day and decided to browse around the pool setting files and found this option: define('YAAMP_FEES_EXCHANGE', 2);
Basically, for pools that does the auto-exchange feature, the pool owner can set any exchange fee's they want. Some pool owners are more transparent and disclose it but I've seen some where they don't mention it at all. So just wanted to let people know that there is also a backend exchange fee that goes into place on top of the pool mining fee. Thanks for this info |

I have been looking for all the source releases of Bitcoin and I am surprised that there is not one place to have them all. With time they alse becomes nearly impossible to compile without the dependencies pre-compiled too. I know that http://www.bitcointrading.com/forum/bitcoin-clients/original-bitcoin-source-code-archives/had some, but this website is giving back an error. Sourceforge has deleted all the work posted there when it moved to Github. Github has version 0.11 up to latest (0.17.0.1 at the moment) but the dependencies are almost impossible to get for the old versions, they would not compile without errors with the current depends/compiler versions. Nakamoto institute has pre versions until 0.13 https://satoshi.nakamotoinstitute.org/code/But where are the version in between? And are there version WITH the dependencies so that they can be modified for learning and compiled? If you get some, I will host them permanently on a domain and guarantee that they will be still here as long as I am alive. The idea would be to have as many as possible version, ready to be compiled (with pre-compiled dependencies) on windows, Linux, MAC... as many as possible. Today, I cannot find any old version that would be included with dependencies and easy to compile. |

Thanks for your answers, things are more clear now  The blockchain will continue to grow forever, only the mining reward is decreasing.
Does this means that if no more Bitcoins are generated, the blocks are still created at the same speed (2016/10 min average) and the blockchain still running with the same number of transaction maximum possible / day?
Yes, assuming there aren't any technology (which can solve scaling problem) applied to Bitcoin. Also does this means that Bitcoin can continue to work without miners, just using these blocks automatically generated every 10 min?
No, miners is still needed. Additionally, they still get reward from transaction fee from transaction which included on blocks they mine. Blocks and Bitcoins are not the same thing I understand. Blocks can host transactions, or mining rewards, that are a special kind of transaction. The max number of transaction is constant, but the bitcoin creation is halved every 4 years.
Am I right?
Yes, block can host/store transaction. In fact, all transaction must stored/included in blocks. Yes, block must have coinbase transaction, which is transaction about mining reward for the miner/pool. No, maximum transaction amount on blocks depends on each transaction size. Yes, bitcoin creation mining reward is halved every 4 years. |

Thanks for all these answers. To resume... The blockchain will continue to grow forever, only the mining reward is decreasing. Does this means that if no more Bitcoins are generated, the blocks are still created at the same speed (2016/10 min average) and the blockchain still running with the same number of transaction maximum possible / day? Also does this means that Bitcoin can continue to work without miners, just using these blocks automatically generated every 10 min? I guess not, because the miners are creating the blocks right? Is there a possibility that blocks can be not used (at the early stages for example)? Blocks and Bitcoins are not the same thing I understand. Blocks are hosting transactions, or mining rewards, that are a special kind of transaction. The max number of transaction is constant, but the bitcoin creation is halved every 4 years. Am I right? You clearly need to learn more about Bitcoin Transaction are stored in a block... but the number of blocks created is lowered every 4 years.
You meant block mining reward, block time interval is still same (even though actually it's 0.6 minutes faster) The number of transactions is increasing because of the popularity of Bitcoin.
How can Bitcoin will scale in the future if the number of blocks are lower, and the number of transactions is increasing, there must be a breaking point where it will not be possible to mine enough to satisfy the incoming number of transactions?
What limits bitcoin scaling is Bitcoin's block size/weight and there's almost no correlation between scaling and mining reward. But there are multiple technology to solve/reduce the problem such as LN and MuSig Schnorr Another question with the same idea, at the early stage of Bitcoin, when there were not enough transactions to fill these blocks, many blocks must have been generated, but empty. Does this mean that a large part of the blockchain is filled by empty blocks or blocks that are not totally used?
Yes, earlier block isn't full, but still used/generated as each block must have at least one transaction (which is coinbase transaction). But no need to worry about this as each block don't reserve 1MB storage space. |

What about the optimization of this blockchain?

I know it will not mine anything and it is not the idea, but I would like to know if anyone had made a mining block function. It is for testing how the blockchain is working, not to mine bitcoin. I would like to have something equivalent to this program written in Python, but as a function that could be run from the chainparams.cpp initialisation for example. The idea is that with such a function, it would be possible to mine the first blocks of a new blockchain, or mine any type of algorithm, since it would run inside the wallet at the initialisation. If no one did it already I will do it myself but if it already exists, why re-create the wheel? Here is the code in python that I have found. https://gist.githubusercontent.com/shirriff/cd5c66da6ba21a96bb26/raw/85a75b2fc2457f9e8bf5c148fde98b5ddd2094c3/mine.pyimport hashlib, struct

There are some Mining guru here and I am stuck in the development of my coin, I request some help to get my coin started. I am using ccminer to mine my own coin with Yiimp. I have setup everything and everything seems to work except that I get a lot of errors and it won't mine. My coin is virgin, that mean it has never been mined or had any transaction. I have 4 peer connected, I have set the difficulty to 1, my coin is a fork of Bitcoin Core 0.17.0.1, RPC port is 1790, main port is 1789 Mining address was created like this: ./bitcoin-cli getnewaddress

Sorry for the long debug log, there is a lot more... anyone can help me figure out what is the problem? |

So the Bitcoin core have removed cpumining, and gpumining and now most RPC mining options are not working.
What about the ones who are doing a fork to create an altcoin? Why not keeping these features for the ones who are creating altcoins from Bitcoin.
Bitcoin has been forked +20000 times, and now what if you cannot mine your fork?
Because people are not going to install your empty wallet in a pool.
Or you need to create a pool just to mine your first transactions?!
If I do a fork of Bitcoin, how I can mine my new coin now that Bitcoin core has dumped these part of the code?
|

Not sure to understand your English. But apparently latest Bitcoin 0.17 cannot solo mine, and is incompatible with all cpuminer flavors, because the RPC commands have been removed. That's not nice for the Altcoins they already hardcode it. that why many not know . there something about new bitcoin that bip you need know that what must do. on mean time prefer used rebase code~ Here sample of transaction receive by mining. did you look off the debug.log? |

How your answer can help anyone? Is this forum to blame people for asking questions? |

getwalletinfo give no key, wallet name is empty... I have created my own blockchain so there is no transaction... I have seen many people having the same problem and no solution. generate or generatetoaddress is not doing anything. However if I do getnewaddress I get a new address, but this address is not saved, or not visible in the getwalletinfo

I have an issue with this parameter? --coinbase-addr XQg3PmNxX9oEbxsymqtQHir6dkPpVPTJ6P
How do you get an address if you never mined any block? My wallet is loading and never syncing, I have no address.
Do I miss something?
Note: I have done my own genesis using genesis.cpp as instructed.
on cli you need type : getwalletinfo there will info wallet active. but you know today is hard code. you need rebase code for easy~ |

I have my altcoin working with 3 seeding servers... all are connected and there is no error message. I have done my genesis but NO TRANSACTION has been done yet. It is a virgin coin if you like.
I can run the QT wallet fine, and everything seems ok I see the nodes listed in the Debugging->pairs and the network debugging panel is showing activity.
However, the wallets in all servers are loading but never sync, which do not allows me to have an address and mine.
I have a progress at 0%, Number of blocks = 0 and the last block time is the time I have done the genesis.
Any help is welcome at this point.
Thanks

I am doing an altcoin: I want to have an halving every year (210000/4 block or so) and I want to distribute 28028* COIN to the miners with a halving of 1.61 Also I pre-mine 100 Billions Am I doing anything wrong? Programmers, let me know your feedback  CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
CAmount nSubsidy=0;
double halvings = nHeight / consensusParams.nSubsidyHalvingInterval; // no need to be an int with new algo
if(nHeight == 3) // block 3 is pre-mining
{
CAmount nSubsidy = 100000000000 * COIN; // premine 100 billions
halvings=1.0;
}else {
CAmount nSubsidy = 28028 * COIN;
int years = (int) nHeight/52560; // 210000/4
halvings = (years/1.618033988750);
}
if (halvings<=1.0) halvings=1.0;
nSubsidy = nSubsidy / halvings;
return nSubsidy;
}

satoshi liked maths and the Fibonacci sequence
its well documented
ill show you just 2 numbers found in the Fibonacci sequence and leave you to see how often they appear

Ok I was wong on the number of minutes in a year (525600)
My mistake, now it makes sense!
Thanks

If Bitcoin delivered 50 coins every 10 minutes (600 seconds) the first year, then it should have delivered 50 x (1577000/10) = 7885000 Bitcoin the first year. But I cannot see this number in any charts like in this one for example where it is said that the first years were added 2625000 bitcoins. https://en.bitcoin.it/wiki/Controlled_supplySo what is the exact formulas to determine how many bitcoins are issued / year (before halfing) |
