Cryptocurrency difficulty explained in spanish

It is also possible to get a Bitcoin address using an account at an exchange or online wallet service. One of the differences between using bitcoin and using regular money online is that bitcoin can be used without having an internet connection to link any sort of real-world identity to it.

Unless someone chooses to link their name to a bitcoin address, it is hard to tell who owns the address. Bitcoin does not keep track of users; it keeps track of addresses where the money is. Each address has two important pieces of cryptographic information, or keys: a public one and a private one. The public key, which is what the "bitcoin address" is created from, is similar to an email address; anyone can look it up and send bitcoins to it. The private address, or private key, is similar to an email password; only with it can the owner send bitcoins from it.

Because of this, it is very important that this private key is kept secret. To send bitcoins from an address, you prove to the network that you own the private key that belongs to the address, without revealing the private key. This is done with a branch of mathematics known as public-key cryptography. A public key is what determines the ownership of bitcoins, and is very similar to an ID number.

If someone wanted to send you bitcoins, all you would need to do is supply them your bitcoin address, which is a version of your public key that is easier to read and type. Anyone using the system can see how much money "ABC" has and how much money "DEF" has, but they cannot tell anything about who owns the address. But Bob and Alice each have a second key which only they individually know. This is the private key, and it is the "other half" of a Bitcoin address.

The private key is never shared, and allows the owner of the bitcoins to control them. However, if the private key is not kept secret, then anyone who sees it can also control and take the bitcoins there. The person who took it, told others about it later, saying "I'll send it back once Matt gives me a new address, since someone else can sweep [empty] out the old one. Sites or users using the Bitcoin system are required to use a global database called blockchain.

Blockchain is a record of all transactions that have taken place in the Bitcoin network. It also keeps track of new bitcoins as they are generated. With these two facts, the blockchain can keep track of who has how much money at all times. To generate a bitcoin, a miner must solve a math problem. However, the difficulty of the math problem depends on how many people are mining for bitcoin at the moment. Because of how complicated the math problems usually are, they must be calculated with very powerful processors.

The process of generating the bitcoins is called mining. Miners either compete with one another or work together in groups to solve a mathematical puzzle. The first miner or group of miners to solve the particular puzzle are rewarded with new bitcoins. The puzzle is determined by the transactions being sent at the time and the previous puzzle solution.

This means the solution to one puzzle is always different from the puzzles before. Attempting to change an earlier transaction, maybe to fake bitcoins being sent or change the number of someone's bitcoins, requires solving that puzzle again, which takes a lot of work, and also requires solving each of the following puzzles, which takes even more work.

This means a bitcoin cheater needs to outpace all the other bitcoin miners to change the bitcoin history. This makes the bitcoin blockchain very safe to use. A popular image associated with Bitcoin is a QR code. QR codes are a group of black and white boxes that are similar to barcodes.

Barcodes are a row of lines, and QR codes are a grid of squares. Bitcoin uses QR codes because they can store more information in a small space, and a camera such as a smartphone can read them. The two QR codes on the Bitcoin note are the public and private addresses, and can be scanned with a number of online tools. Not all Bitcoin users do Bitcoin mining, and it is not an easy way to make money.

Peer-to-peer refers to systems that work like an organized collective by allowing each individual to interact directly with the others. In the case of Bitcoin, the network is built in such a way that each user is broadcasting the transactions of other users. And, crucially, no bank is required as a third party. A private key is a secret piece of data that proves your right to spend bitcoins from a specific wallet through a cryptographic signature.

Your private key s are stored in your computer if you use a software wallet; they are stored on some remote servers if you use a web wallet. Private keys must never be revealed as they allow you to spend bitcoins for their respective Bitcoin wallet. A cryptographic signature is a mathematical mechanism that allows someone to prove ownership. In the case of Bitcoin, a Bitcoin wallet and its private key s are linked by some mathematical magic.

When your Bitcoin software signs a transaction with the appropriate private key, the whole network can see that the signature matches the bitcoins being spent. However, there is no way for the world to guess your private key to steal your hard-earned bitcoins. A Bitcoin wallet is loosely the equivalent of a physical wallet on the Bitcoin network.

The wallet actually contains your private key s which allow you to spend the bitcoins allocated to it in the block chain. Each Bitcoin wallet can show you the total balance of all bitcoins it controls and lets you pay a specific amount to a specific person, just like a real wallet. This is different to credit cards where you are charged by the merchant.

Make a donation. Some Bitcoin words you might hear Bitcoin provides a new approach to payments and, as such, there are some new words that might become a part of your vocabulary. Address A Bitcoin address is similar to a physical address or an email.

Bit Bit is a common unit used to designate a sub-unit of a bitcoin - 1,, bits is equal to 1 bitcoin BTC. Bitcoin Bitcoin - with capitalization, is used when describing the concept of Bitcoin, or the entire network itself. Block Chain The block chain is a public record of Bitcoin transactions in chronological order. Block A block is a record in the block chain that contains and confirms many waiting transactions. Confirmation Confirmation means that a transaction has been processed by the network and is highly unlikely to be reversed.

Cryptography Cryptography is the branch of mathematics that lets us create mathematical proofs that provide high levels of security. Double Spend If a malicious user tries to spend their bitcoins to two different recipients at the same time , this is double spending. Hash Rate The hash rate is the measuring unit of the processing power of the Bitcoin network. Mining Bitcoin mining is the process of making computer hardware do mathematical calculations for the Bitcoin network to confirm transactions and increase security.

P2P Peer-to-peer refers to systems that work like an organized collective by allowing each individual to interact directly with the others. Private Key A private key is a secret piece of data that proves your right to spend bitcoins from a specific wallet through a cryptographic signature.

It's going to be kind of a response associated with this challenge. It has a very specific mathematical property in relation to this challenge. And as you point out, maybe when I talk about a challenge string here, for example in the context of spam, this challenge string might actually represent an email message. So it's going to be something very specific to the task at hand.

Now what the prover will do is come up with a response string, and let's call the response string r. Actually, let's use the term p for it, since maybe we can think of it as a proof, a proof or a response. And the idea is that the prover will come up with this proof or response string, and he has to come up with a string such that, when you concatenate the challenge and the response, and you take the two together, and you apply a cryptographic hash function-- so let's say I come up with a cryptographic hash function, like SHA, or anything of that nature.

If I take the challenge string and the proof string and concatenate together and apply the cryptographic hash function, apply these mathematical transformations that represent the cryptographic hash function, I want to come up with a proof string such that the output under this hash function will have a very specific property.

The prefix of the output, the first large number of bits will all be 0. So let's say the first 40 bits, or first 30 bits, or some number of bits will be 0. And then the other bits can be whatever they would normally be. So obviously, what you're trying to do here is come up with a proof string that has a relationship with the challenge string.

And that relationship happens to be one that is taken with respect to a particular hash function, and really incorporates or considers what the output of the hash function will be when the proof string is concatenated with the challenge string. And if you, let's say, have a good cryptographic hash function, then the only known way to find this type of a proof string is to effectively try a lot of different possibilities, effectively doing brute force, by trying a lot of different proof strings until you find one that works.

Now if you, let's say, needed to find an output that contained about 40 consecutive 0's in it, that would require you to perform about 2 to the power 40 steps, 2 to the power 40 different hash function indications. You'd have to try 2 to the 40 different strings, and one of them what would likely work if you tried 2 to the 40 such strings. That actually requires you to try about, and 2 to the 40 just to give you a sense, is approximately 1 trillion.

So if you tried a trillion different strings out, and you hashed them each, you would likely come up with one string that had the first 40 bits being 0. Now sometimes it might take you a lot less than a trillion steps. Sometimes it might take you a little bit more. You may get very lucky. You might get very unlucky. But on average, it will take you about 1 trillion steps to find a string where the first 40 bits are equal to 0.

So this is something that's not easy, but it's also not outside the realm of possibility. Now to understand why it's really hard to solve these types of proof of work schemes more efficiently than maybe simply doing brute force, I think it's helpful to recall that the output of a cryptographic hash function looks more or less random.

In fact, each output bit looks like a series of coin flips. So it's kind of like flipping the coin, and if it comes up heads, you would have a 0, and if it comes up tails, you can think of it as a 1. And so what you're really doing is saying, if I flipped 40 coins, what are the odds that you would have 40 consecutive heads on those 40 coin flips? Now obviously that likelihood is very small, but it's not outside the realm of possibility.

If you flipped 40 coins and you flipped those 40 coins about a trillion times, you would actually expect to see one instance in which all 40 coins came up as heads out of a trillion tries. Now one interesting thing with these proof of work schemes, is they can be ratcheted up or ratcheted down. So for example, let's say you want to require even more computational heavy lifting to come up with a correct proof string.

Let's say you want to increase the work that's going to be proved here. What you can effectively do, in that case, is you could just increase the requirement on a number of leading 0's. So every time you add an additional 0, you effectively double the computational horsepower needed on average.

And that's because you effectively requiring one more coin flip to come up heads, and that entails doubling the number of coin flips. So if I had 41 coin flips and I required 41 straight heads, that would require about twice as much effort as just requiring 40 straight heads. And likewise, every time you remove a 0 from consideration, or the requirement, that will reduce the computational horsepower needed to about half of what it was previously. So for example, if I only required the first 39 bits to be 0, that would require about half as many coin flips as requiring the first 40 bits to be 0.

Now the neat thing is that once you come up with a solution-- let's say that somebody tries a trillion times and they finally come up with a proof string that works-- it's very easy to validate that this proof string is in fact a correct proof of work. All you have to do is, you take the challenge and you take the proof string and you hash them together.

So for example, if somebody proposes this one string, let's call it p prime, all you do is you take the challenge and you take p prime, and you input them into a hash function, and you see if the first 40 bits are all 0. So all this requires you to do is apply a hash function once to the concatenation of c and p prime, and you can verify that the output indeed has the requisite number of 0's in front of it.

Bitstamp vs Kraken: is Bitstamp safe? Is Kraken safe? Kraken fees vs Bitstamp fees? All questions answered in this full Bitstamp vs Kraken guide. In the early s, most people were still struggling to understand the internet.

However, there were some very clever folks who had already realized what a powerful tool it is. Some of these clever folks, called cypherpunks , thought that governments and corporations had too much power over our lives. They wanted to use the internet to give the people of the world more freely. Using cryptography, cypherpunks wanted to allow users of the internet to have more control over their money and information.

At the top of the cypherpunks, the to-do list was digital cash. DigiCash and Cybercash were both attempts to create a digital money system. They both had some of the six things needed to be cryptocurrencies but neither had all of them. By the end of the the nineties, both had failed. The world would have to wait until before the first fully decentralized digital cash system was created. Its creator had seen the failure of the cypherpunks and thought that they could do better.

Their name was Satoshi Nakamoto and their creation was called Bitcoin. No one knows who Satoshi Nakamoto is. It could be a man, a woman or even a group of people. Satoshi Nakamoto only ever spoke on crypto forums and through emails. In late , Nakamoto published the Bitcoin whitepaper. This was a description of what Bitcoin is and how it works. It became the model for how other cryptocurrencies were designed in the future. On January 12, , Satoshi Nakamoto made the first Bitcoin transaction.

By , Satoshi Nakamoto was gone. Bitcoin became more popular amongst users who saw how important it could become. Today, the price of a single Bitcoin is 7, Which is still a pretty good return, right? In , a programmer bought two pizzas for 10, BTC in one of the first real-world bitcoin transactions. So, Bitcoin has succeeded where other digital cash systems failed. But why?

What is cryptocurrency doing differently? The thing that makes cryptocurrency different from fiat currencies and other attempts at digital cash is blockchain technology. All cryptocurrencies use distributed ledger technology DLT to remove third parties from their systems. DLTs are shared databases where transaction information is recorded. The DLT that most cryptocurrencies use is called blockchain technology. The first blockchain was designed by Satoshi Nakamoto for Bitcoin.

A blockchain is a database of every transaction that has ever happened using a particular cryptocurrency. Groups of information called blocks are added to the database one by one and form a very long list. So, a blockchain is a linear chain of blocks! It stays on the blockchain forever and everyone can see it. The whole database is stored on a network of thousands of computers called nodes.

New information can only be added to the blockchain if more than half of the nodes agree that it is valid and correct. This is called consensus. The idea of consensus is one of the big differences between cryptocurrency and normal banking. At a normal bank, transaction data is stored inside the bank.

Bank staff makes sure that no invalid transactions are made. This is called verification. Unfortunately, George only has 10 USD in his account. They stop the transaction from happening. The bank stopped George from double spending which is a kind of fraud. Banks spend millions of dollars to stop double spending from happening. What is cryptocurrency doing about double spending and how do cryptocurrencies verify transactions?

Cryptocurrency transactions are verified in a process called mining. So, what is cryptocurrency mining and how does it work? Miners are nodes that perform a special task that makes transactions possible. Mining cryptocurrency uses a lot of computer power, so miners are rewarded for the work they do. On the Bitcoin network, miners who confirm new blocks of information are rewarded with Instead of mining for gold or coal crypto, miners are digging for new Bitcoin! It stops double spending without the need to trust centralized accounting as banks do.

They are secured by math done by computers! For more information, check out my Blockchain Explained guide. Now you know how blockchains and crypto mining work. Cryptocurrency only exists on the blockchain. Users access their cryptocurrency using codes called public and private keys.

If you want someone to send you an email, you tell them your email address. Well, if you want someone to send you cryptocurrency, you tell them your public key. Now, if you want to read your emails or send an email, you need to enter your email password.

This is how private keys work. Private keys are like passwords for cryptocurrency. Public keys can be seen by anyone, but private keys should only be seen by you. Private and public keys are kept in wallets. Crypto wallets can be online, offline, software, hardware or even paper. Some can be downloaded for free or are hosted by websites. Others are more expensive. For example, hardware wallets can cost around a hundred US Dollars. You should use several different kinds of wallets when you use cryptocurrency.

Cryptocurrency is pseudonymous, remember? There is no way to prove your own cryptocurrency unless you have the keys to it. Bitcoin changed the way people think about money. Hundreds of other cryptocurrencies have been created since and they all want to change the world!

Ethereum has quickly skyrocketed in value since its introduction in , and it is now the 2nd most valuable cryptocurrency by market cap. Would you like to know more about Ethereum? They can do all kinds of cool things. These cryptocurrencies and many others are available to buy and sell on crypto exchanges.

So, what is cryptocurrency trading? Buying and selling cryptocurrencies has become a very big business. The total value of all the cryptocurrencies in the world is more than billion US Dollars. You can trade online with crypto exchanges like Binance, Bitstamp, and Coinbase. You can also arrange to trade cryptocurrencies in-person with peer-to-peer sites like LocalBitcoins.
