Bitcoin has certainly generated a lot of attention in recent years. This is an entirely digital currency that is fully encrypted. As such, it gives people a level of autonomy that they are not able to possess when using other currency types. With a traditional monetary system, money is printed by government bodies on an as-needed basis. Ideally, this physical currency is backed by an equal amount of valuable metals like gold or silver. With bitcoin, however, there is never a need to print any tangible money. Instead, this digital currency is discovered by a number of miners. Computers all throughout the glove are constantly mining for coins as part of an ongoing competition. Following is everything you need to know about how bitcoin mining works.
People are constantly sending this digital currency to one another via the bitcoin network. In order to keep track of who is sending what to whom, however, a digital record must be maintained. This is accomplished by the bitcoin network itself. It collects every one of the transactions completed over a set amount of time and compiles it into a list. This list is referred to as a block. As a miner, your job will be to confirm each of these transactions and to then record these into a ledger.
The ledger is basically made up of a lengthy list of blocks that is referred to as a blockchain. You can use this blockchain to review and explore various transactions between different points of the network and different addresses. Once a new blockchain is made, it is added to the existing one so that the record spans all transactions that have ever occurred via this digital network. All parties who participate in bitcoin mining are given their own updated copy of this chain that is constantly updated. This ensures that all relevant parties have a clear understanding of all that’s happening throughout the system.
Trust is a key part of this process, especially given that all of the records are both digital and encrypted. Without miners, there would be now way of ensuring that the system is never tampered with or that it’s able to remain fully in tact. When new block chains are created, miners put them through specific verification and protection process by applying mathematical formulas to the information within the block. This in turn encrypts it or converts the data. The result is a much shorter sequence of numbers and letters. It is comprised of a large amount of data but happens to be incredibly compact. All hashes have to be unique. If even a single character is changed, the entire hash will be completely altered.
There are a number of unique properties that hashes possess. While producing a unique hash from bitcoin block data is not all that complex, determining what this hash means in terms of the data it contains is virtually impossible. Various other forms of data is incorporated into the block. This is represented by the hash of the very last information that is included in the chain. As such, outside parties could never look at a hash to determine which transactions occurred within the block chain, or who these transaction occurred between.
Given that the hash for every block is made using the block that came before it, this is not unlike a wax seal. It serves as a digital confirmation that the current block and all that follow are legitimate. If someone were to tamper with it, the effects would be all too obvious. Moreover, the hash for a block would change if you attempted to complete an illegitimate transaction. As such, bitcoin participants would be immediately aware of this false activity.
All of this is accomplished with special software that has been specifically for bitcoin mining. Whenever a hash is completed, the person responsible for this ever will be rewarded with a total of 25 coins or bitcoins. This transaction will also be added to the blockchain via an update and all bitcoin participants will find out. This gives people incentive to continue mining for these coins, which in term promotes new transactions and the preservation of the entire system overall.
One challenge that this system faces is the fact that producing hashes from data accumulated through transactions is by now means easy. Computers happen to be quite adept in these efforts. This is purposefully made to be quite difficult so that random people are not entering the fray and thereby undermining the overall integrity of the entire systems. A hash must have a very specific look in order to be accepted by the system. Otherwise, people would be able to successfully mine bitcoins within just a matter of minutes.
