The world of cryptocurrencies is growing at an accelerated pace. The crypto market cap continues to grow with record breaking volumes. The basis for creating value in the crypto world is the mining process for major and veteran coins – with Bitcoin leading them.
While the coins of the “old world” as we all know, were and still are issued by centralized bodies such as banks and governments, and are created as printed bills or banknotes, the process of creating money in the world of crypto is decentralized.
The decentralization is done using the blockchain technology. Blockchain, is a type of a ledger that confirms transactions and lives in a distributed-fashion in the cloud. In other words, a group of computers around the world holds copies of the order books and for any given change in it, all the copies are updated. When a majority of the computers authorize a transaction, the money is securely transferred and added to the next block which will be written.
In 2009, Bitcoin was one of the first applications of the blockchain. Since the invention of money, the problem of centralization has always existed. Although it was temporarily solved in the era of the gold rush, when every ordinary man could mine gold and generate money, since then, banks and credit companies took control over the money, shifted over to working with credit, and practically cut off the connection to gold itself and created a monopoly on printing money. Bitcoin returned the possibility of generating money for everyone. It is no coincidence that the process of generating cryptocurrencies is called “Mining”.
What is the mining process?
The blockchain allows the transfer of funds in a decentralized manner, while security and fraud-prevention are carried out by encryption, hence the name crypto, as cryptography is the discipline of encryption. Encrypting and verifying a transaction requires work. Computers which do this kind of work, which is basically solving a mathematical puzzle, get to write the next block in the chain, and are rewarded with coins for it – this is practically the mining operation. The more miners a network has, the stronger it is and the faster and more secure it is.
Meet the Mining Pools
As solving these mathematical puzzles had become difficult, mining pools are being used. A mining pool is a joint effort between miners, so that even a miner with a relatively small amount of processing power can enjoy the reward, without having to solve the whole mathematical puzzle by himself, as it requires a lot of computing power (Hash rate). In the early days of Bitcoin, it was possible to mine Bitcoin with a standard processor of a personal computer (CPU mining). Afterwards, as the network grew bigger, the difficulty of solving these puzzles grew too, and it was no longer possible to mine using a CPU. For this reason, people shifted to using powerful “gamers” graphics card processes (GPU mining), as their design solves those puzzles much faster than a CPU. The next step was to shift over to ASICs (Application Specific Integrated Circuits which are basically dedicated machines built for the sole purpose of mining). Today, Bitcoin’s network is so heavy, that nobody can mine Bitcoin by themselves. As an individual miner’s power is relatively small, he will probably not be able to solve any puzzle before other more powerful miners do and new puzzles are issued, resulting in wasted work which practically gives zero income (in theory, an individual can solve a puzzle by themselves, but with Bitcoin the chances of success are smaller than winning the lottery).
For this reason, miners started to work in groups, which are called pools. A pool of miners unites the calculation power of a workforce of small miners in order to obtain a significant mining power (aka hash rate), thus increasing the chance of solving a puzzle and getting the reward for it. Each miner in the pool, gets a “share” of the reward, according to the amount of power he contributed to the pool.
