Isn’t Bitcoin mining a waste bitcoin mining calculator gaiden walkthrough for zelda energy? How does mining help secure Bitcoin? What do I need to start mining? How do I calculate my Bitcoin mining profitability?
What is a Bitcoin mining pool? What is a Bitcoin mining share? What is a Bitcoin mining module? Where can I view mining data about each block? Mining is the process of spending computing power to process transactions, secure the network, and keeps everyone in the system synchronized together.
It can be perceived like the Bitcoin data center except that it has been designed to be fully decentralized with miners operating in all countries and no individual having control over the network. This process is referred to as “mining” as an analogy to gold mining because it is also a temporary mechanism used to issue new bitcoins. Unlike gold mining, however, Bitcoin mining provides a reward in exchange for useful services required to operate a secure payment network. Mining will still be required after the last bitcoin is issued. Anybody can become a Bitcoin miner by running Bitcoin mining software and Bitcoin mining modules with specialized Bitcoin mining hardware. Mining software listens for transaction broadcasts through the peer-to-peer network and performs appropriate tasks to process and confirm these transactions. For new transactions to be confirmed, they need to be included in a block along with a mathematical proof of work.
Such proofs are very hard to generate because there is no way to create them other than by trying billions of calculations per second. This requires miners to perform these calculations before their blocks are accepted by the network and before they are rewarded. The proof of work is also designed to depend on the previous block to force a chronological order in the block chain. This makes it exponentially difficult to reverse previous transactions because this requires the recalculation of the proofs of work of all the subsequent blocks. Bitcoin miners are neither able to cheat by increasing their own reward nor process fraudulent transactions that could corrupt the Bitcoin network because all Bitcoin nodes would reject any block that contains invalid data as per the rules of the Bitcoin protocol. Consequently, the network remains secure even if not all Bitcoin miners can be trusted. Spending energy to secure and operate a payment system is hardly a waste.
Like any other payment service, the use of Bitcoin entails processing costs. Services necessary for the operation of currently widespread monetary systems, such as banks, credit cards, and armored vehicles, also use a lot of energy. Bitcoin mining has been designed to become more optimized over time with specialized hardware consuming less energy, and the operating costs of mining should continue to be proportional to demand. When Bitcoin mining becomes too competitive and less profitable, some miners choose to stop their activities. An optimally efficient mining network is one that isn’t actually consuming any extra energy. While this is an ideal, the economics of mining are such that miners individually strive toward it. Mining creates the equivalent of a competitive lottery that makes it very difficult for anyone to consecutively add new blocks of transactions into the block chain.
