![]() If it is never, your break-even time has been calculated to be greater than 10 years. This is likely due to a large diff change value which causes your predicted profitability to turn negative in the future. You could try lowering the diff changeįor a less agressive prediction or disable it altogether. What is this? The profitability chart can help you visualize your long term mining projections. The chart can operate in one of three views: Total Profits The Total Profits view predicts what your overall profitability will be in the future. This view assumes the price of the coin will stay the This is calculated by taking your current profits and adding them to each following months profits while factoring in the changing difficulty (diff change), the diff change factor can be disabled. ![]() If you wish to account for a changing price (ie if you think the price will rise in the future), switch to the "Coins Generated" view. Coins Generated This view looks at the number of coins you can expect to generate in the future. This view does not account for any expenses, it simply predicts how many coins you will generate with your given hashrate and the diff change value. A high diff change will cause you to generate fewer coins in the future. Total Costs This view sums your power and recurring costs. It can be used to predict the total cost to operate your mine over a given period of time. What is this? Selling Profile tells the calculator how to use the Price Change value. Price Change must be set to something other than 0 to have any effect on the profitability projections. Selling Profile has 4 different options: Sell Coins Monthly Profitability is calculated as if you were to sell all of your mined coins at the end of each month. Please go to the GitHub repository to download the code.Your profits will equal (money earned from selling) - (total expenses + hardware costs) Sell to Cover Expenses Only sell enough crypto to cover your monthly expenses. The following python program calculates and verifies the hash of a block. The hash value must be equal or smaller than the target value defined by the difficulty bits (bits).The manually calculated hash value must match with the hash value which was sent by the block creator (miner).There are two conditions for the hash of a block, The little-endian format of that SHA-256 value is the hash value of the block. Let’s get the SHA-256 value of the appended parameters. Now we can append all the parameters together. #Decimal Value 2083236893 #Hex Value 0x7c2bac1d #Little endian encoding 0x1dac2b7c Calculating the Hash Value #Decimal Value 486604799 #Little endian encoding 0xffff001d Nonce The difficulty bits are in decimal format. #Decimal value 1231006505 #Hex values 0x495fab29 #Little endian encoding 0x29ab5f49 Difficulty bits Translate the merkle root to a little endian hex. ![]() Translate the previous block hash to a little endian hex. #Big endian encoding 0x00000001 #Little endian encoding 0x01000000 Previous block hash Translate the version into a little-endian hex. The version of a block is a decimal number which is denoted by 4 bytes. ![]()
