So this is a function where you can guess that the input based on the output is very easy to do something where the output-based input is a little difficult to estimate.

For example, which two numbers will be included in 9? Well, it could be four and five, three and six, or nine and zero. I have typos zero and nine, so B should be nine, so it's a little harder to guess, but a little harder in encryption where the input strings enter and a popular hash is generated. If you know the hash function, it's just a hash function that will generate a 256 bit long hash in hexadecimal. It is impossible to estimate. If I give you a hash to guess at x, it is almost impossible for you to try the error and try it differently and find out. Which produces the desired result, so let me show you a couple of shaw patterns. We say that if you have an axis it would be a 64-bit hexadecimal number, but I'm not displaying the number in such a way that when you have a period or period when any character changes, it's a whole hash Will change so you can't guess exactly what it is. It's kind of random, but every time you say Shaw 256 Abd, he'll make the same product, which is why it's so temporary but guess what. The road is very difficult. This is a simple eternal code where you can write python code in just three lines to create a shaw of any string and 256 she is, therefore, an insightful hash function. The original block is not created in Coin or Blockchain. The transaction is just another component, so it has a block number, it results in a hash, and then the bitcoin protocol happens to convert the whole block into a chain, so it says There is a block transaction in it. On the previous number Hashish. Take what you do and supply. There will be 256 functions in this series and now he will create a hash. The protocol requires that the first digit of this hash be zero to how many digits? Well, that changes from time to time. I think it's 30 digits, but at some point when it starts it was low, so we say that the first four digits of the hash must be zero for our difficulty level. To add. Now let's see if it converts it to just a string and creates a hash when the first four zeros in the hash can't be zero, so you need a new thing called nuns.

Nine codes are like numbers and add that number to a string and see if you can create a hash that has the first four digits as zero because our difficulty level here is zero. Now we say don't make this hash so you have to guess that you have to convert the bread into two checks, this is the first four-digit zero. no. Then change it to three or four so you can guess. You're running around four loops and you guess it, try one such loop to get started, let's say it hits a trillion or a trillion, and your ultimate goal is to create a hash. Where the first four. The number is zero, right? We say I go to this number and my hash comes first. The first four digits are zeros. So you can say that this block has been confirmed or this block has been confirmed and the nonsense has been estimated. This process is bitcoin mining, so we said the first four zeros here, in fact, it's like thirty zeros sixty zeros from time to time depending on the weather and for all these miners they are not doing any rocket science. ۔ If they are not working algorithmically, you can mine bitcoin and write code. Right now, after this theory session, it's very easy to do a loop where you're testing with different people and trying to find a hash where the first digit digits for those miners in bitcoin mining are zero So he got the award in 2009. If you block anything from me, you will get 50 bitcoins every four years, which are cut in half. In 2020, the reward is 6.25. Okay fine? In 2024, it will be halved, and the bitcoin is worth 28,000 today, so you would think of this 28 as 6,000.

## Bitcoin mining in Python

Python Code Python Bitcoin MiningWe will first be writing bitcoin mining code in less than 15 lines of code. I will first cover some of the ideas behind the blockchain and then we will write the code. The encoding timestamp is given below.

So if you know the theory behind blockchain, if you know how it works, you can jump straight into coding. Bitcoin is nothing more than a ledger. What is a ledger? I have given you an example of a ledger. Here is a set of transactions.

## Bitcoin mining

So we'll pass this as a parameter, then we say the block number I want is five. Just doing something The transaction is a transaction and we say it was an old hash and I'm just copying to save some time. Let's say the hash above is fine and my difficulty. Nothing difficult, but you zero. Facing a lot of what you want. Your hash should say it's four, so I provide my worries, well, using all of them, we need to make 256 which is the first four digits as zero, so I have a whip. Be firm and then I will reduce my flaws. Text So my text is like a block number and the block number is number one so I need to convert it to a string transaction. There is a rope in the back. And nuns are number one, so make it a string. I get the whole wire of the whole block, in which I say 256. And this is the new hash that I get from this function. Okay, let's try this with your post first. If there is one when I run it, I see that I have this hash, but if my first four digits are not zero, then I try to give the nun two, they are not zero yet. I'm just typing three, do you think I'll keep trying different programs? Well no, if you're not a dumb programmer, are you clearly looping? If you write it will say, what is my limit? Well, let's talk about it.

Let's say the maximum number is OK. This maximum number depends on your counting power. I mean, you can literally get an infinite loop on you, but I'll limit it to a large number and, for that matter, run the loop you're trying differently. The nuns are trying to create a new hash. Now the new hash should have zero as the first four digits, how do you check that I'm passing here as four before zero? I'm going to open the inactive, which means that usually when I'm coding, I open the idle. Let's try different things, let's say I have some strings, let's do some hashing. Well, this dragon has started a function that starts, so if you start two, three, four it will say zero. But if you do something else, it will be wrong. So I want to see if this series starts with the first 4 0, doesn't start, so that's wrong, how do I start now? How can I check all four zeros? You want to get four strings of four numbers so the easiest way is to say multiply from 0 to 4 and this will give you the prefix that you will see that it is a common python string. My string is the top zero, so the previous zeros in the zeros and zeros are fine, and when your new hash counts, check to see if the new hash starts. A big payoff, which you'll want to print, you know, I'm against this block, well I'm against the block and I won 6.5. I'm fine after trading Bitcoin multiple times, it's stupid and even after trading for a long time, if you don't get anything, you can usually increase the discount until I Said unless you run an infinite loop. You get the answer or you run a loop until your account budget runs out, then you get a discount saying it's okay, it's too much work, not profitable You know, I'm making bitcoins, but at the top of it, my power. And my hardware costs are rising so I'm throwing an exception? So now we are ready to run it. Let's run this mining code so that this mining can happen really fast so you managed to loop 2425 times and got the hash when you enter the first four digits as zero. I added that in case of difficulty in the size of the hash it will take a long time which will take time so I am going to add a code to measure the time in which it will fix the given block. ۔ Time, but I don't know how much time. Then we add the timer code again. I'm going to copy and paste something to save time so you can import the time module when the time comes. Time indicates if this is your current time, right? And then you do your mining and after mining, you realize that by doing so you know the total time. I have been taking time stamps from here since it was abolished from the beginning where I got full-time for mining. It was a second and I will print it so let's run it so that mining is happening now and it is taking some time now, we will know that it took 12 seconds to find the answer, but you will have an idea like that Bitcoin mining is nothing more. Guessing how to play online games, if you win, gives you a special reward.

## Bitcoin minings

Anyone can do it and you are right there are thousands of people who are digging but the thing is that it seems easy to guess but we will see in the code that it takes more time, this algorithm It's not about. This is because the code is simple, but it takes a lot of math power, strength to guess correctly, and if 10 people guess who guesses correctly first will be rewarded. , Then walk for 10 minutes. Then the other person guesses that the person doesn't get rewarded, so that's the theory. After all, blockchain seems to be where the last hash of each block is referenced, so they can see that I have the previous hash in this block 2. If you look From 0 0 to 3 Y As the number of transactions increases, the blockchain gets longer and longer. It's like a chain, so it includes more blocks and those who are mining. Who is doing this nonsense so that what you are doing is repeated? Let's get involved in coding to assess this accident. Now I opened my Patcher Community Edition and created this file where I imported the hash lab module to be able to use the Shaw 256 function. I will go to my zen meditation mode so there is no hassle, so try this 256 function first and you know what, so I'm just giving random strings and I'm right that this code is fine Need to encode Unicode objects so you have to put in the ski code and ok you need to encode the original wire. What you need to know is that this is Jesus and He will give you 256 items. What if you want to extract a real hash from it? All you have to say is out of the hexadecimal summary, right? It will then give you the original 256 bits, so if you count these digits, they are 64. But it's hexadecimal and each hexadecimal digit has 4 bits, so they're actually 256 bits or 64 bits in hexadecimal terms.

So now I have this function, so I will develop a great utility function so that you know that I can use it to write 256s and then return it instead of ABC input. The supply is OK and if the low score name is equal to the low score man then this is the entry point of my main engine and I will try to call the function 256 stars 256 and it looks like it is fine before we work now Is working Mine here, so we need the transaction first, so let's do some dummy transactions, then we say I have transactions. Let's say the devil is giving you a brother-in-law with my brother. Say 20 bitcoins and Mandlorine Kara are giving my friend 45 bitcoins and now I need to write a function called my name that will take care of this transaction. So you know that the mining function will create a new hash with the transaction and some parameters and this is the hash we want, so I will print this new hash here, in addition to this transaction now, the input parameters What are? Gee works fine, let's go back to our function and see in our regret that we say in our representation that in our representation we saw that the hash is nothing, but it's called wire branch 256, so what is this? Is? There are some things all over China that have block numbers. Your transaction. It has a back hash and some nuns. If you're just guessing, you'll need the parameters that make up our function. So I will pass all these parameters. I am also before zero. In our presentation, the previous zero in real life at that time was four. The bitcoin zero is actually 20.
