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.
"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."
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.
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.

BTC Mining Calculator
Select your miner from the drop down below and the calculator automatically produces a daily and monthly profit output based on the current price of BTC. You may also customize the power usage field and cost per KWh to run various scenarios.
Earnings, ROI, co-locating/hosting and profit simulations are calculated based on current BTC prices which are elastic, volatile and ever changing. ASIC Network Inc. does not promise or guarantee that earnings, returns on investment, or profits will be similar or equal to the simulated values herein. ASIC Network Inc. does not guarantee the lifespan of equipment or the viability, profitability, or stability of bitcoin.
Disclaimer: Earning and returns are estimated based on Bitcoin's daily price - a value asicnetwork.io dynamically pulls from the blockchain.info website. BTC currently has a difficulty of 20082t. Both price and mining difficulty are subject to change at any given moment. Profit simulations are estimated based on mining at today's earning rate. ASIC Network does not guarantee earnings, return on investme, or profits to be accurate or true as it is subject to daily fluctuations and volatility based on Bitcoin price. Bitcoin mining difficulty and the lifespan of the equipment are also factors to consider.
