Principle
1. Bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (through competitive computing to generate a consensus blockchain at each node. The blockchain is a distributed public authoritative account book, including all the transactions in the bitcoin network).
2. Bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times. At this time, the workload proof mechanism will play a role. When a node finds the solution of matching requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block.
3. Nakamoto compares the generation of bitcoin by consuming the power and time of CPU to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain. Each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target
What is an ASIC Bitcoin Miner?
Since it’s now impossible to profitably mine Bitcoin with your computer, you’ll need specialized hardware called ASICs.
Here’s what an ASIC miner looks like up close:
Originally, Bitcoin’s creator intended for Bitcoin to be mined on CPUs (your laptop or desktop computer). However, Bitcoin miners discovered they could get more hashing power from graphic cards. Graphic cards were then surpassed by ASICs (Application Specific Integrated Circuits).
Think of a Bitcoin ASIC as specialized Bitcoin mining computers, Bitcoin mining machines, or “bitcoin generators”.
Nowadays all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware ASICs, usually in thermally-regulated data-centers with low-cost electricity.
Most Efficient Bitcoin Miners
Good Bitcoin mining hardware needs to have a high hash rate. But, efficiency is just as important.
An efficient Bitcoin miner means that you pay less in electricity costs per hash.
To improve your efficiency, there are also companies that will let you order hardware to their warehouse and run the miners for you.
You could also cloud mine bitcoins, though these deals are usually scams. Both options are also a lot less fun than running your hardware!
