SHA256 Hashing Algorithm is a cryptographic algorithm used by crypto miners to prove that they have done the work required to solve a block. Miners use their SHA256 computational power (hashing speed) and submit nonce values as an attempt to find a hash value of a given difficulty. The bitcoin network automatically changes its difficulty every 2016 blocks, or roughly every two weeks in order to keep mining time at ten minutes on average.
The cost of mining bitcoin varies, depending on the price of bitcoin, hardware efficiency, difficulty, and power consumption.
"Difficulty" is a bitcoin mining term that relates to how difficult it is for bitcoin miners to find the hash value needed for their nonce. Difficulty values are updated based on total network hashing power and adjusted every 2016 "blocks."
A bitcoin mining pool is a mining group that works together with bitcoin miners to solve the bitcoin network's proof-of-work algorithm.
SHA256 encryption (Secure Hashing Algorithm) is bitcoin's standard algorithm to encrypt information. SHA256 encryption uses a complex mathematical formula that creates 256-bit hash values for data input as well as bitcoin transactions.
As long as transactions occur with the bitcoin economy, bitcoin mining will continue.
Bitcoin's SHA-256 hashing algorithm is considered "brute force" as it relates to bitcoin mining rigs, and it becomes more difficult over time. This creates an arms race where the bitcoin miner with the most powerful single rig will solve blocks at a faster rate than competitors and accumulate bitcoins on this basis. Miners need to keep upgrading their equipment in order for bitcoin mining activity to remain profitable because difficulty levels adjust accordingly based on network hashrate changes every 2016 blocks or roughly every two weeks. This ensures that bitcoin miners have access to computational resources necessary to secure global bitcoin transactions from tampering by other parties when performing verification of payment authorization before committing those funds to a transaction.
