Difficulty: Bitcoin Difficulty: 711,697,198,174 Estimated Next Difficulty: Adjust time: Hashrate(?): 5,053,848,849 GH/s Block Generation Time(?): Updated: Chart Explained The difficulty.The estimated next difficulty.Average block generation time of 2016 blocks.Block generation time is also known as confirmation time.Average block generation time of 1008 blocks.If grey line less than blue line, The generation time is decreasing.The more grey line is lower than blue line, the faster generation time is decreasing.After 2016 blocks generated, Bitcoin will adjust difficulty to estimated difficulty in order to keep the block generation time at 600 seconds.Difficulty History Date Difficulty Change Hash Rate Jun 17 2017 711,697,198,174 5,094,526,985 GH/s Jun 04 2017 678,760,110,083 4,858,754,124 GH/s May 23 2017 595,921,917,085 4,265,775,241 GH/s May 10 2017 559,970,892,891 4,008,427,786 GH/s Apr 27 2017 521,974,519,554 3,736,439,151 GH/s Apr 13 2017 520,808,749,422 3,728,094,244 GH/s Mar 30 2017 499,635,929,817 3,576,533,297 GH/s Mar 17 2017 475,705,205,062 3,405,230,497 GH/s Mar 03 2017 460,769,358,091 3,298,315,540 GH/s Feb 18 2017 440,779,902,287 3,155,225,442 GH/s Feb 04 2017 422,170,566,884 3,022,014,630 GH/s Jan 22 2017 392,963,262,344 2,812,940,600 GH/s Jan 10 2017 336,899,932,796 2,411,623,656 GH/s Dec 28 2016 317,688,400,354 2,274,102,150 GH/s Dec 15 2016 310,153,855,703 2,220,167,778 GH/s Dec 02 2016 286,765,766,821 2,052,749,317 GH/s Nov 18 2016 281,800,917,193 2,017,209,539 GH/s Nov 05 2016 254,620,187,304 1,822,642,296 GH/s Oct 22 2016 253,618,246,641 1,815,470,125 GH/s Oct 08 2016 258,522,748,405 1,850,577,916 GH/s Sep 25 2016 241,227,200,230 1,726,771,560 GH/s Sep 12 2016 225,832,872,179 1,616,574,667 GH/s Aug 29 2016 220,755,908,330 1,580,232,344 GH/s Aug 15 2016 217,375,482,757 1,556,034,316 GH/s Aug 02 2016 201,893,210,853 1,445,207,896 GH/s Jul 18 2016 213,492,501,108 1,528,238,850 GH/s Jul 04 2016 213,398,925,331 1,527,569,009 GH/s Jun 21 2016 209,453,158,595 1,499,324,110 GH/s Jun 08 2016 196,061,423,940 1,403,462,340 GH/s May 24 2016 199,312,067,531 1,426,731,353 GH/s May 11 2016 194,254,820,283 1,390,530,167 GH/s Apr 28 2016 178,659,257,773 1,278,892,782 GH/s Apr 14 2016 178,678,307,672 1,279,029,147 GH/s Apr 01 2016 166,851,513,283 1,194,369,655 GH/s Mar 18 2016 165,496,835,118 1,184,672,491 GH/s Mar 04 2016 158,427,203,767 1,134,066,098 GH/s Feb 19 2016 163,491,654,909 1,170,318,852 GH/s Feb 07 2016 144,116,447,847 1,031,625,717 GH/s Jan 26 2016 120,033,340,651 859,232,121 GH/s Jan 13 2016 113,354,299,801 811,421,684 GH/s Dec 31 2015 103,880,340,815 743,604,444 GH/s Dec 18 2015 93,448,670,796 668,931,642 GH/s Dec 06 2015 79,102,380,900 566,236,898 GH/s Nov 24 2015 72,722,780,643 520,569,941 GH/s Nov 11 2015 65,848,255,180 471,360,171 GH/s Oct 29 2015 62,253,982,450 445,631,364 GH/s Oct 15 2015 60,883,825,480 435,823,399 GH/s Oct 01 2015 60,813,224,039 435,318,014 GH/s Sep 17 2015 59,335,351,234 424,738,988 GH/s

I'm looking into mining, how it works, and how to get started.I see a "mining difficulty" from many sources and list a 3 billion something number without units.What exactly does this number mean and how does it relate to the processing speed of the hardware used?For example, what predictions can be made on the number blocks you will solve with a 100 Gh/s ASIC at any given difficulty?I assume Gh/s is giga hashes per second, though I don't know what a hash is either.bitcoin ardI found this related question, but I don't understand the answer.bitcoin mining and luckAs an extension question, how might this relate to mining in a pool?bitcoin wert 2014Bitminter says it has 424 Th/s, so my 100 Gh/s is a drop in the bucket.difficulty hash hashpower up vote 4 down vote (If I may repeat myself a bit...)

Mining is like having a lot of people throwing weighted coins (such that 1 millionth of the time it comes up heads) and telling you when they hit a heads.If one such "heads" is reported every 10 minutes (600 seconds), you can make a very accurate estimation of how many times per second the coins are being flipped.In this example: (1,000,000 flips/heads) / (600 seconds/heads) ~= 1,667 flips/second The network difficulty is how you adjust this 1,000,000 figure so that the 600 figure stays consistent as the network's total hash power (1,667) changes.To see real-world calculations of how the difficulty affects the coins discovered per time spent, see any mining profitability calculator, and change the "difficulty" figure.The Bitcoin wiki has details on difficulty, as well.I don't know what a hash is either.When mining, your computer creates a block of data, which has a list of all of the transactions it knows about, includes a transaction that pays you the mining bonus, and then hashes that.

If the hash happens to be a small enough number (as defined by the difficulty), the block is valid.If it's not, you increment a random number called a "nonce" that's in the block, so that the block has the same meaning but different data, and hashes the block again.(the nonce is included from the start, of course, but I didn't mention it to avoid being confusing) The details of the block hash are explained in more detail at Bitcoin wiki's Block hashing algorithm.Gigahashes per second, then, are how many billion times your hardware can do this hash per second.If the pool you're in has 424 Th/s and you have 100 Gh/s, then you are about 1/4000th of your pool's total power.You can expect to be the one to solve about 1/4000th of the blocks (on average) that your pool finds.(technical details intentionally omitted; those are available at my various links, and your link) up vote 3 down vote Miners task is to find a hash below a target T. Obviously if T is smaller, its more difficult to find the hash number.

Difficulty D is defined by: D = Tmax/T where Tmax is: 2^224 The probability of finding the hash is: P = T/2^256 which is equal to 1/D2^32 So if you can make h number of hashes in t time, the probability of finding the target hash is: P = ht/D2^32 up vote 1 down vote I'm looking into mining, how it works, and how to get started.The difficulty is just an arbitrary value, it has no unit.A difficulty 8 block is 8 times more difficult than a difficulty.Today the difficulty is 3B, but this chances on a bi-weekly basis as the hashrate of the network varies.It takes about 4 Billion attempts to find a difficulty 1 block, you can scale up approximately from here.100 GH means the hardware makes 100,000,000,000 attempts a second, or about a difficulty 1 block every 0.04 seconds.In practice a 100GH machine might find a block every 5 years or so, if you're lucky.Pooled mining pools the resources to find blocks faster and split the income between the miners.
