Mining is the process of adding new bitcoins to the money supply. Mining also serves to protect the bitcoin system against fraudulent transactions or transactions where the same amount of bitcoin is used more than once, also known as double consumption. Miners provide processing power to the bitcoin network in exchange for the opportunity to be rewarded with bitcoin.

Miners validate new transactions and record them in the ledger. Every 10 minutes, a new block of transactions that have occurred since the last block is "mined," adding those transactions to the blockchain. Transactions that become part of a block and are added to the blockchain are considered "confirmed," allowing new bitcoin owners to use the bitcoin they received in those transactions.

Why does Bitcoin need miners?
Mining is basically a process of auditing and verifying Bitcoin transactions to avoid the "double consumption" problem. In double spending, a person with cryptocurrency tries to use the same currency twice. With physical money you cannot buy a drink in a pub with a £20 note and then go to the shops and do some shopping with the same £20 note.

With cryptocurrencies, there is a risk that someone with Bitcoin will make a copy of that Bitcoin and send it to a merchant instead of the real thing. In the real world, cash is a £20 note just to make sure it's not fake, which is what Bitcoin miners are trying to do with the cryptocurrency; they double check that no transaction has taken place.

Why Bitcoin needs miners
Blockchain mining is a metaphor for the computational work done by network nodes in the hope of obtaining new tokens. In fact, miners are essentially paid for their work as accountants. They do the work to verify the legitimacy of Bitcoin transactions.

My hardware
All of this means that in order to compete competitively, miners must now invest in powerful computing devices, such as a graphics processing unit (GPU) or, more realistically, an application-specific integrated circuit (ASIC). These can range from $500 to tens of thousands of dollars. Some miners, especially Ethereum miners, buy separate graphics cards as a cheap way to merge mining.

Today, Bitcoin mining hardware consists almost exclusively of ASIC machines, which in this case specifically do one thing and one thing only: mine bitcoins. Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs, gaining hashing power and energy efficiency every few months as new chips are developed and deployed. Today's miners can produce close to 200 TH/s at just 27.5 joules per teraash.

We have just released the new Bitcoin Halving mine called MicroBT Whatsminer M30s++ with 112 Tera hash, and it is the world's first fastest Bitcoin ASIC mine.
M30S++ offers (112 TH/s) Tera Hashes per. second with an excellent power consumption of 3100 watts per. Hash Tera.
Model Whatsminer M30S++ SHA-256 mining algorithm with a maximum hash rate of 112Th/s for a power consumption of 3100W.

Model: M30s++ offers (112 TH/s) Tera Hashes per second with a single power consumption of 31 Watts. Model Whatsminer M30s++ SHA-256 mining algorithm with a maximum hash rate of 112 Th/s for a power consumption of 3100W.

Our most popular miner just got better. The Whatsminer M30s 112T mines SHA-256 algorithm with powerful 112 TH/S hash rate with only 3100W power consumption.

It is built with the most advanced technology with 2 fans and a noise level of 70 db for extra heat dissipation and long life. The Whatsminer M30s ++ 112T requires an Ethernet network connection and has an automatic 12V power supply with all power inputs. Its compact size and weight make it easy to use and transport. The allowable operating temperature of the product is between -5° and 35°C.
