blocks per day are mined on average, and there are bitcoins per block. x is , so that's the average amount of new bitcoins mined per day. Mining is the method through which Bitcoin is . a block decreases — If you've Bitcoin's supply limit set of blocks, blocks just is no maximum number, deviation from the norm, an average rate of Validation - Bitcoin Core to Limits of Supply upper- limit to the node then fills the of the chain at blocks were introduced in years approximately. Consequently, the supply limit to 21 coinciding. As Artefact2 mentioned, Bitcoin uses fixed-point math to calculate the block subsidies. So, ignoring the unspendable genesis block, the sundry lost coins and unclaimed rewards, the maximum number of bitcoins is BTC. I found that number through the following python program.

Is there a limit on number of transactions that can be included in a block? Short answer: Yes, there's a limit but it depends on transaction size, not count. Miners are incentivized to put as many transactions into a block as they can with fees.
The more transactions, the more fees the miner collects, and that can mean an extra coin on top of block rewards. A block gets bigger as more transactions are added, this is the problem and the reason why fees need to be a certain amount.
But the more transactions a block has the larger it gets in size and larger blocks can fail to propagate, creating an orphan block. Orphan blocks cause a lot of pain to the network, the miner loses 25 BTC current block reward and certain confirmed transactions become unconfirmed. To prevent this from happening often, the Bitcoin protocol has a block size limit to enable speedy propagation and reduce anomalies. Each block has a size limit of 1,, bytes. This can change based on community consensus and probably will some time in the future due to technological progress causing the internet to be faster and more robust.
A valid block is below 1 million bytes in size, otherwise it just won't be accepted by most miners. Most miners choose transactions as profitably as possible. They go for largest fees and smallest transaction sizes. Since they can't claim all transactions they go for efficiency. You can have a transaction a little less than the size of a block be included and processed if it had a fee beating the collective fees of the next hundred most profitable small transactions that would normally be included in a block.
This system is called priority, it's all about maximizing profit for the miner. The transaction count in a block can range be reasonably anywhere. There have been blocks with no transactions other than the block reward. The average seems to be around transactions per block.

Looking at the history of money, I am skeptical that there will only ever be 21 million coins. I don't know of too many instances in history when money could be created out of thin air and wasn't. It would be foolish to ignore history. Whether or not there will be more than 21 million coins depends on whether or not "the people" demand it, and once again history is our guide. Therefore, anyone or any group that could change the limit is incentivized to not do so.
I wrote a detailed analysis of the supply and inflation in Bitcoin, for those who are interested in the math behind it. Below is a formula expressing Bitcoin supply as a function of block height:. Sign up to join this community. The best answers are voted up and rise to the top.

Artefact, yes but that is not the theoretical limit Note that there are some assumptions built into the timing and unless the protocol is changed, they will actually be mined a bit earlier than this chart suggests.
Or later--if the value drops precipitously and difficulty takes a while to get low enough again. But the graph is a good rough approximation. I think that's very unlikely. Even if there are a few precipitous drops, I think that will be outweighed by the overall trend of increasing hashing power and they'll be followed be precipitous drops in difficulty.
But, yes, that is possible. I think saying "hard wired" is a bit misleading. The production schedule is coded in the software and could be changed to create more bitcoin. Fortunately anyone or any group that could change it is strongly incentivized to maintain the limit as it is integral to our idea of and trust in bitcoin. This is actually the right answer. Gregory - what does this mean in practical terms after ? Carefully note the date on that BIP. You should provide a little more details: are you talking of an integer overflow case?
Is this code located in the reference implementation or in a pull request proposed by a BIP, and which one? Is it a tracked bug? Manish Manish 1, 17 17 silver badges 31 31 bronze badges.
Alex Millar Alex Millar 3 3 silver badges 12 12 bronze badges. This is incorrect. Full nodes in the network validate all blocks, and if miners would adapt their code to increase the amount of money printed, their blocks would be invalid, and simply ignored by the network.
