Everyone can see that someone is sending a transaction but the transaction cannot be linked to anyone because no one knows who the acting parties are. As long as honest nodes control a network and you are connecting to a node known to be reliable, this verification is reliable. However, to ensure that transactions are not being fabricated by an attacker on an invalid chain, Satoshi Nakamoto suggests that businesses utilising Bitcoin for frequent payments should run their own nodes for speed and increased security. At the time of the publication of the Bitcoin whitepaper in 2008, it was estimated that at least 4.2MB of memory storage would be needed per year. This was based on the assumption that blocks are generated every ten minutes and each block is equal to 80 bytes. Per hour, this would be equal to 80 multiplied by 6, then multiplied by the cost per day and then per year, i.e. equivalent to 80b multiplied by multiplied by 365.

You can use your existing personal computer to use mining software compatible with Bitcoin and join a mining pool. Mining pools are groups of miners that combine their computational power to compete with the large ASIC mining farms. When Bitcoin was first released, it was possible to mine it competitively on a personal computer; however, as it became more popular, more miners joined the network, which lowered the chances of being the one to solve the hash. You can still use your personal computer as a miner if it has newer hardware, but the chances of solving a hash individually are minuscule.

Transactions are placed into a queue to be validated by miners within the network. Miners in the Bitcoin blockchain network all attempt to verify the same transaction simultaneously. The mining software and hardware work to solve the nonce, a four-byte number included in the block header that miners are attempting to solve. When a transaction takes place on the blockchain, information from the previous block is copied to a new block with the new data, encrypted, and the transaction is verified by validators—called miners—in the network. When a transaction is verified, a new block is opened, and a Bitcoin is created and given as a reward to the miner who verified the data within the block—they are then free to use it, hold it, or sell it. As the first decentralized virtual currency to meet widespread popularity and success, Bitcoin has inspired a host of other cryptocurrencies in its wake.
