''See also: [[target]]''

=== What is "difficulty"? ===

Difficulty is a measure of how difficult it is to find a hash below a given target.

The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this target.
Mining pools also have a pool-specific share difficulty setting a lower limit for shares.

=== How often does the network difficulty change? ===

Every 2016 [[block|blocks]].

=== What is the formula for difficulty? ===

difficulty = difficulty_1_target / current_target

(target is a 256 bit number)

difficulty_1_target can be different for various ways to measure difficulty.
Traditionally, it represents a hash where the leading 32 bits are zero and the rest are one (this is known as "pool difficulty" or "pdiff").
The Bitcoin protocol represents targets as a custom floating point type with limited precision; as a result, Bitcoin clients often approximate difficulty based on this (this is known as "bdiff").

===How is difficulty stored in blocks?===

Each block stores a packed representation (called "Bits") for its actual hexadecimal [[target]]. The target can be derived from it via a predefined formula. For example, if the packed target in the block is 0x1b0404cb, the hexadecimal target is
0x0404cb * 2**(8*(0x1b - 3)) = 0x00000000000404CB000000000000000000000000000000000000000000000000

Note that the 0x0404cb value is a signed value in this format. The largest legal value for this field is 0x7fffff. To make a larger value you must shift it down one full byte. Also 0x008000 is the smallest positive valid value.

===How is difficulty calculated? What is the difference between bdiff and pdiff?===

The highest possible target (difficulty 1) is defined as 0x1d00ffff, which gives us a hex target of
0x00ffff * 2**(8*(0x1d - 3)) = 0x00000000FFFF0000000000000000000000000000000000000000000000000000

It should be noted that pooled mining often uses non-truncated targets, which puts "pool difficulty 1" at
0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

So the difficulty at 0x1b0404cb is therefore:
0x00000000FFFF0000000000000000000000000000000000000000000000000000 /
0x00000000000404CB000000000000000000000000000000000000000000000000
= 16307.420938523983 (bdiff)
And:
0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF /
0x00000000000404CB000000000000000000000000000000000000000000000000
= 16307.669773817162 (pdiff)

Here's a fast way to calculate bitcoin difficulty. It uses a modified Taylor series for the logarithm (you can see tutorials on flipcode and wikipedia) and relies on logs to transform the difficulty calculation:

<source lang="cpp">
#include <iostream>
#include <cmath>

inline float fast_log(float val)
{
int * const exp_ptr = reinterpret_cast <int *>(&val);
int x = *exp_ptr;
const int log_2 = ((x >> 23) & 255) - 128;
x &= ~(255 << 23);
x += 127 << 23;
*exp_ptr = x;

val = ((-1.0f/3) * val + 2) * val - 2.0f/3;
return ((val + log_2) * 0.69314718f);
}

float difficulty(unsigned int bits)
{
static double max_body = fast_log(0x00ffff), scaland = fast_log(256);
return exp(max_body - fast_log(bits & 0x00ffffff) + scaland * (0x1d - ((bits & 0xff000000) >> 24)));
}

int main()
{
std::cout << difficulty(0x1b0404cb) << std::endl;
return 0;
}
</source>

To see the math to go from the normal difficulty calculations (which require large big ints bigger than the space in any normal integer) to the calculation above, here's some python:

<source lang="python">
import decimal, math
l = math.log
e = math.e

print 0x00ffff * 2**(8*(0x1d - 3)) / float(0x0404cb * 2**(8*(0x1b - 3)))
print l(0x00ffff * 2**(8*(0x1d - 3)) / float(0x0404cb * 2**(8*(0x1b - 3))))
print l(0x00ffff * 2**(8*(0x1d - 3))) - l(0x0404cb * 2**(8*(0x1b - 3)))
print l(0x00ffff) + l(2**(8*(0x1d - 3))) - l(0x0404cb) - l(2**(8*(0x1b - 3)))
print l(0x00ffff) + (8*(0x1d - 3))*l(2) - l(0x0404cb) - (8*(0x1b - 3))*l(2)
print l(0x00ffff / float(0x0404cb)) + (8*(0x1d - 3))*l(2) - (8*(0x1b - 3))*l(2)
print l(0x00ffff / float(0x0404cb)) + (0x1d - 0x1b)*l(2**8)
</source>

=== What is the current difficulty? ===
[http://blockexplorer.com/q/getdifficulty Current difficulty], as output by Bitcoin's getDifficulty.

[http://bitcoin.sipa.be Graphs]

=== What is the maximum difficulty? ===

There is no minimum target. The maximum difficulty is roughly: maximum_target / 1 (since 0 would result in infinity), which is a ridiculously huge number (about 2^224).

The actual maximum difficulty is when current_target=0, but we would not be able to calculate the difficulty if that happened. (fortunately it never will, so we're ok.)

=== Can the network difficulty go down? ===
Yes it can. See discussion in [[target]].

=== What is the minimum difficulty? ===
The minimum difficulty, when the target is at the maximum allowed value, is 1.

=== What network hash rate results in a given difficulty? ===
The difficulty is adjusted every 2016 blocks based on the [[Block_timestamp|time]] it took to find the previous 2016 blocks. At the desired rate of one block each 10 minutes, 2016 blocks would take exactly two weeks to find. If the previous 2016 blocks took more than two weeks to find, the difficulty is reduced. If they took less than two weeks, the difficulty is increased. The change in difficulty is in proportion to the amount of time over or under two weeks the previous 2016 blocks took to find.

To find a block, the hash must be less than the target. The hash is effectively a random number between 0 and 2**256-1. The offset for difficulty 1 is
0xffff * 2**208
and for difficulty D is
(0xffff * 2**208)/D

The expected number of hashes we need to calculate to find a block with difficulty D is therefore
D * 2**256 / (0xffff * 2**208)
or just
D * 2**48 / 0xffff

The difficulty is set such that the previous 2016 blocks would have been found at the rate of one every 10 minutes, so we were calculating (D * 2**48 / 0xffff) hashes in 600 seconds. That means the hash rate of the network was
D * 2**48 / 0xffff / 600
over the previous 2016 blocks. Can be further simplified to
D * 2**32 / 600
without much loss of accuracy.

At difficulty 1, that is around 7 Mhashes per second.

At the time of writing, the difficulty is 22012.4941572, which means that over the previous set of 2016 blocks found the average network hash rate was
22012.4941572 * 2**32 / 600 = around 157 Ghashes per second.

=== How soon might I expect to generate a block? ===
(The [https://www.bitcointalk.org/index.php?topic=1682.0 eternal question].)

The average time to find a block can be approximated by calculating:
time = difficulty * 2**32 / hashrate
where difficulty is the current difficulty, hashrate is the number of hashes your miner calculates per second, and time is the average in seconds between the blocks you find.

For example, using Python we calculate the average time to generate a block using a 1Ghash/s mining rig when the difficulty is 20000:
$ python -c "print 20000 * 2**32 / 10**9 / 60 / 60.0"
23.85
and find that it takes just under 24 hours on average.

* Any one grinding of the hash stands the same chance of "winning" as any other. The numbers game is how many attempts your hardware can make per second.
* You need to know the difficulty (above) and your khash/sec rate (reported by the client).
** [[Mining Hardware Comparison]] has some stats that may help you predict what you could get.
* Visit a calculator or perform the maths yourself,

Buying Bitcoins (the newbie version)

2014-03-09T11:44:01Z

ChupaChup:

This page aims to be the best resource for new users to understand how to buy Bitcoins. The existing [[Buying bitcoins]] page is too complex.

'''For a practical getting started guide check out [http://ofirbeigel.bitcoinse.hop.clickbank.net?page=risk-free Bitcoin Secrets]'''

Read [https://en.bitcoin.it/wiki/How_To_Buy_Bitcoins_With_Your_Credit_Card How To Buy Bitcoins With Your Credit Card], for information about buying Bitcoins with a credit card.

{{Counterparty-warning}}

===PayPal===

[http://bitcoin.stackexchange.com/questions/2293/how-can-i-buy-bitcoin-via-a-credit-card-or-paypal You can't directly buy Bitcoins using PayPal], because it is risky for the seller, and therefore few sellers will offer this. There are basically 3 reasons for that:

* The buyer of bitcoins can always perform a chargeback and there is no way for the seller to contest that

* There are many hacked accounts and when PayPal realizes that such an account has been fraudulently used, they will also perform a chargeback

* PayPal doesn't like bitcoin, as the bitcoin network is in direct competition to it. They will ban accounts that have anything to do with Bitcoins, and freeze their balance.

Having said that there is a [http://99bitcoins.com/buying-bitcoins-with-paypal-a-practical-guide/ workaround] that can be done in order to use Paypal to buy Bitcoins but it holds within it higher transaction fees. Using the [http://VirrWox.com Virtual World Exchange] you can buy Second Life Lindens (SLL) with Paypal and then convert your SLL to Bitcoins. This process will charge you transaction fees of around 6% but will let you purchase Bitcoins pretty quickly as opposed to a wire transfer. The reason this method works is because you do not buy Bitcoins with Paypal directly, you only buy SLL with Paypal (which is acceptable by Paypal's TOS) and then exchange your SLL to Bitcoin.

'''Note''': If you only want to take advantage of Bitcoin's price volatility You can trade CFDs on Bitcoin via Paypal on sites like [http://Ava-Trade.co.uk AvaTrade] or [http://99bitcoins.com/plus500 Plus500]. When trading online your capital may be at risk. Trading CFDs is suitable for more experienced traders.

=== Anonymity ===
There is a huge demand for buying Bitcoins off the grid due to ever-increasing government regulations and private agency intrusions and discrimination against alternative currencies.
Due to the possibility of facial recognition cameras at banks and the paper trail involved with credit cards, there are very few options to have high levels of anonymity when buying Bitcoins those ways. DNA, Fingerprints, phone and internet records, audio and video records will not be discussed, but they all are possible tools which attackers could use to uncloak even the stealthiest Bitcoin buyer.
There are a couple known ways, depending on your location, to buy Bitcoins outside of the standard banking system with relatively high anonymity.
Buying locally with cash using a burner or payphone allows a high level of anonymity with the exchange being the weakest link.
Many sellers online will also trade Bitcoins for [[MoneyPak]] codes or other cash-like gift codes which can be bought at a local store with cash.
Another way to buy Bitcoins with a high level of anonymity is by sending cash in the mail.

=== Exchanges ===

Is bitcoin mining profitable

2014-02-18T10:16:40Z

ChupaChup:

This page aims to give a beginners explanation to the question "Is Bitcoin Mining Profitable ?"

===Profitability Variables===

In order to determine the profitability of Bitcoin mining you need to take into account the following parameters:

'''Network Hash Rate''' - What is the combined computing power of all of the network miners.

'''Network mining difficulty''' - As more miners join the network the network difficulty increases in order to mine a constant amount of Bitcoins in a given time period.

'''Electricity rate''' - How much money are you paying per per KW for running your miner.

'''Power consumption''' - How much power is your miner consuming. This is measured in Watts and can be found here.

'''Time frame''' - how long are you considering mining for.

'''Cost of mining hardware''' - as described.

'''BTC conversion rate''' - this is only important if you want to exchange your BTC to a different currency. If you wish to only gain Bitcoins you can disregard this variable, but since most people want to profit in some other currency it usually is important.

===The problem of profitability decline===

The biggest variable that can not be predicted is how much will the difficulty increase throughout time. This will in turn cause a profitability decline. In order to take this variable into account, several mining profitability calculators have incorporated a "profitability decline" factor. This factor of course is an educated guess at the most.

==The problem of variating BTC exchange rate==

Much like the network's difficulty, the Bitcoin's exchange rate can also not be predicted. It may stay the same throughout your predicted time frame, increase or collapse completely. This also makes predictions of mining profitability inaccurate.

===Mining profitability in 2014===

Taking the above mentioned variables into account and considering the Bitcoin network's leap in difficulty at the end of 2013 it is currently not profitable to mine Bitcoins from your own home. Other alternatives can be mining through a could mining service or mining Altcoins and exchanging them to Bitcoin.

Always choose somebody with many reviews.

=== Anonymity ===
There is a HUGE demand for buying Bitcoins off the grid due to ever-increasing government regulations and private agency intrusions and discrimination against alternative currencies.
Due to the possibility of facial recognition cameras at banks and the paper trail involved with credit cards, there are very few options to have high levels of anonymity when buying Bitcoins those ways. DNA, Fingerprints, phone and internet records, audio and video records will not be discussed, but they all are possible tools which attackers could use to uncloak even the stealthiest Bitcoin buyer.
There are a couple known ways, depending on your location, to buy Bitcoins outside of the standard banking system with relatively high anonymity.
Buying locally with cash using a burner or payphone allows a high level of anonymity with the exchange being the weakest link.
Many sellers online will also trade Bitcoins for [[MoneyPak]] codes or other cash-like gift codes which can be bought at a local store with cash.
Another way to buy Bitcoins with a high level of anonymity is by sending cash in the mail.

=== Bitinstant ===
Extremely unreliable service. Taken down indefinitely as of 12:25 AM GMT 07/15/13.

The largest and most trusted exchange is [[MtGox]]. For a list of other major exchanges see [[Buying_bitcoins#Major_Exchanges|Major Exchanges]]

{{Counterparty-warning}}

===PayPal===
[http://bitcoin.stackexchange.com/questions/2293/how-can-i-buy-bitcoin-via-a-credit-card-or-paypal You can't directly buy Bitcoins using PayPal], because it is risky for the seller, and therefore few sellers will offer this. There are basically 3 reasons for that:
* The buyer of bitcoins can always perform a chargeback and there is no way for the seller to contest that
* There are many hacked accounts and when PayPal realizes that such an account has been fraudulently used, they will also perform a chargeback
* PayPal doesn't like bitcoin, as the bitcoin network is in direct competition to it? . They will ban accounts that have anything to do with Bitcoins, and freeze their balance.

Having said that there is a [http://bitcoinwithpaypal.com workaround] that can be done in order to use Paypal to buy Bitcoins but it holds within it higher transaction fees. Using the [http://VirrWox.com Virtual World Exchange] you can buy Second Life Lindens (SLL) with Paypal and then convert your SLL to Bitcoins. This process will charge you transaction fees of around 6% but will let you purchase Bitcoins pretty quickly as opposed to a wire transfer. The reason this method works is because you do not buy Bitcoins with Paypal directly, you only buy SLL with Paypal (which is acceptable by Paypal's TOS) and then exchange your SLL to Bitcoin.

'''Note:''' If you only want to take advantage of Bitcoin's price volatility You can trade CFDs on Bitcoin via Paypal on sites like [http://Ava-Trade.co.uk AvaTrade] or [http://bitcoinwithpaypal.com/plus500 Plus500]. When trading online your capital may be at risk. Trading CFDs is suitable for more experienced traders.

=== Anonymity ===
There is a HUGE demand for buying Bitcoins off the grid due to ever-increasing government regulations and private agency intrusions and discrimination against alternative currencies.
Due to the possibility of facial recognition cameras at banks and the paper trail involved with credit cards, there are very few options to have high levels of anonymity when buying Bitcoins those ways. DNA, Fingerprints, phone and internet records, audio and video records will not be discussed, but they all are possible tools which attackers could use to uncloak even the stealthiest Bitcoin buyer.
There are a couple known ways, depending on your location, to buy Bitcoins outside of the standard banking system with relatively high anonymity.
Buying locally with cash using a burner or payphone allows a high level of anonymity with the exchange being the weakest link.
Many sellers online will also trade Bitcoins for [[MoneyPak]] codes or other cash-like gift codes which can be bought at a local store with cash.
Another way to buy Bitcoins with a high level of anonymity is by sending cash in the mail.
