Next bitcoin block halving numbers
The block height is just the number of blocks connected together in the block chain. You will get back. The same logic applies to bitcoin transactions. Bitcoin transactions are made up of inputs and outputs. A confirmation means that the bitcoin transaction has been verified by the network, through the process known as mining. Once a transaction is confirmed, it cannot be reversed or double spent. Transactions are included in blocks. Difficulty is directly related to Bitcoin mining see mining below , and how hard it is to verify blocks in the Bitcoin network.
Bitcoin adjusts the mining difficulty of verifying blocks every blocks. Difficulty is automatically adjusted to keep block verification times at ten minutes. If someone tries to send a bitcoin transaction to two different recipients at the same time, this is double spending. Once a bitcoin transaction is confirmed, it makes it nearly impossible to double spend it. The more confirmations that a transaction has, the harder it is to double spend the bitcoins. A private key is a string of data that shows you have access to bitcoins in a specific wallet.
Think of a private key like a password; private keys must never be revealed to anyone but you, as they allow you to spend the bitcoins from your bitcoin wallet through a cryptographic signature.

Block Height The block height is just the number of blocks connected together in the block chain. Confirmation A confirmation means that the bitcoin transaction has been verified by the network, through the process known as mining.

Double Spend If someone tries to send a bitcoin transaction to two different recipients at the same time, this is double spending. Halving Bitcoins have a finite supply, which makes them scarce.
Mining Bitcoin mining is the process of using computer hardware to do mathematical calculations for the Bitcoin network in order to confirm transactions. Private Key A private key is a string of data that shows you have access to bitcoins in a specific wallet. Newsletter Subscribe to our newsletter. Below is a table that lays it out from the beginning until so you can get a feel for the progression. Rough numbers only, where we are now in bold. Check out the bitcoin wiki for the full progression.
The answer is a bit philosophical sorry but it is one of the core tenants of bitcoin, controlled supply. We also know exactly how many have been minted at any particular point in time. This is not actually a new concept, proponents of the Austrian School of Economic Thought have been suggesting such a monetary system since the late 19th century.
It separates money from the state similar to how the church was separated from the state in many countries over the past few centuries. It puts the value or price if you like directly into the hands of supply and demand and takes it away from any form of governance.
No matter how much any authority wants they cannot print more, artificially fix or adjust supply in any way in order to manipulate their own and others economies. Supply and demand are kings in bitcoin and since supply is fixed, demand is the only variable and the only way the price of bitcoin is discovered. Because bitcoin cannot be destroyed [3] but can be lost please backup your wallets now this also makes bitcoin a deflationary currency and that is a stark point of difference as to what we have now with our traditional fiat currencies.
Not everyone agrees that a deflationary currency is a good thing, in fact, most traditional economists subscribe to Keynesian Economics and they most definitely don't see it as a good thing. Satoshi never explained why he chose 21 million as the upper limit nor did he explain why he chose 4 years for each halving at least not when I was around or have found later apart from some vague references to gold mines.
Like a lot of numbers in bitcoin they appear to be just arbitrary, perhaps they have some deeper meaning to him but in reality, the numbers are unimportant, what is important is that they exist and the effect controlled supply in a predictable manner that they have.
I wrote a few articles at the time. The block was found on slush's pool by a relatively new user called Laughingbear using a GPU in a standard PC that he normally used to play games.
