Hello friends!! We meet again in my latest article, this time I want to make an article to answer some of the questions asked by our professor @besticofinder, and the questions are: 1. HOW CRYPTOCURRENCY MINING WORK? 2. WHAT IS MINING DIFFICULTY? 3. WHAT ARE THE CHALLENGES FOR CRYPTOCURRENCY MINERS? ![slide-000-1004-bitcoin-cryptocurrencies-580x358.jpg](https://cdn.steemitimages.com/DQmRr2wBaiWZQJ9WxKgLhVrV8qt45xK8zV4dWgDpSbbgJot/slide-000-1004-bitcoin-cryptocurrencies-580x358.jpg) [SOURCE](https://www.investmentweek.co.uk/news/4025987/coinshares-launches-physically-backed-bitcoin-etp-eyes-seven-crypto-launches) # HOW CRYPTOCURRENCY MINING WORK? Bitcoin mining can be interpreted as a Bitcoin mining activity, which is one of the many ways to obtain Bitcoin. As we know, Bitcoin itself is a global financial system that has become a new virtual currency used as a means of payment. As well as being a means to keep records of the flow of financial transactions digitally between other Bitcoin users. When an online transaction using Bitcoin is processed and recorded on the Bitcoin network, this means that there is a movement or transfer of Bitcoin between one Bitcoin user and another user. The Bitcoin network then manages it by collecting all transactions made by users during a certain period into a list called blocks. # WHAT IS MINING DIFFICULTY? To make it easier and safer to record Bitcoin transactions, a computer with sophisticated and reliable specifications is needed. Because the computer will be used to perform many complex and complex calculation activities to support Bitcoin mining activities. ![crypto-mining-gpus-rigs.jpg](https://cdn.steemitimages.com/DQmSSynyPfzuoPdbMwi1S5Fo4JJa4oGemmpPLhw2bKoQLT7/crypto-mining-gpus-rigs.jpg) [SOURCE](https://zvelo.com/what-is-malicious-cryptocurrency-mining) There are at least four computer hardware that can be used to support these activities, such as: CPU (Central Processing Unit), GPU (Graphical Processing Unit), FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit). Of course, with these specifications the price offered is not playing games and is quite a drain on the pocket. # WHAT ARE THE CHALLENGES FOR CRYPTOCURRENCY MINERS? In mining Bitcoin, there is a system that our computer has to solve, this system is a long list of blocks, and is known as a 'blockchain'. This is then used to track every transaction made by many different Bitcoin addresses anywhere on the network. With the increasing number of transactions carried out by Bitcoin users around the world, it makes new transaction blocks that are entered into the Blockchain even longer. And a copy of the block will be continuously updated and then given to everyone who participated, so that anyone can know what every transaction is happening. Hence the system has to be very reliable, and fortunately everything is set up digitally. How can we ensure that the blockchain remains intact, and never breaks? This is where the miners play a role in confirming each of these transactions, then logging them into a system.

Thank you for reading my article, hope it will be useful for you. See you in the next article !! CC: @besticofinder @steemitblog @steemcurator01 @steemcurator02
