How Does a Blockchain Work?
Picture a spreadsheet that is duplicated thousands of times across a network of computers. Then imagine that this network is designed to regularly update this spreadsheet and you have a basic understanding of the blockchain.
Information held on a blockchain exists as a shared — and continually reconciled — database. This is a way of using the network that has obvious benefits. The blockchain database isn’t stored in any single location, meaning the records it keeps are truly public and easily verifiable. No centralized version of this information exists for a hacker to corrupt. Hosted by millions of computers simultaneously, its data is accessible to anyone on the internet.
To go in deeper with the Google spreadsheet analogy, I would like you to read this piece from a blockchain specialist.
“The traditional way of sharing documents with collaboration is to send a Microsoft Word document to another recipient and ask them to make revisions to it. The problem with that scenario is that you need to wait until receiving a return copy before you can see or make other changes because you are locked out of editing it until the other person is done with it. That’s how databases work today. Two owners can’t be messing with the same record at once. That’s how banks maintain money balances and transfers; they briefly lock access (or decrease the balance) while they make a transfer, then update the other side, then re-open access (or update again). With Google Docs (or Google Sheets), both parties have access to the same document at the same time, and the single version of that document is always visible to both of them. It is like a shared ledger, but it is a shared document. The distributed part comes into play when sharing involves a number of people.
Imagine the number of legal documents that should be used that way. Instead of passing them to each other, losing track of versions, and not being in sync with the other version, why can’t *all* business documents become shared instead of transferred back and forth? So many types of legal contracts would be ideal for that kind of workflow. You don’t need a blockchain to share documents, but the shared documents analogy is a powerful one.” – William Mougayar, Venture advisor, 4x entrepreneur, marketer, strategist, and blockchain specialist
The reason why the blockchain has gained so much admiration is that:
It is not owned by a single entity, hence it is decentralized
The data is cryptographically stored inside
The blockchain is immutable, so no one can tamper with the data that is inside the blockchain
The blockchain is transparent so one can track the data if they want to
The Three Pillars of Blockchain Technology
The three main properties of Blockchain Technology which have helped it gain widespread acclaim are as follows:
Decentralization
Transparency
Immutability
Pillar #1: Decentralization
Before Bitcoin and BitTorrent came along, we were more used to centralized services. The idea is very simple. You have a centralized entity that stored all the data and you’d have to interact solely with this entity to get whatever information you required.
Another example of a centralized system is the banks. They store all your money, and the only way that you can pay someone is by going through the bank.
The traditional client-server model is a perfect example of this:
What is Blockchain
When you google search for something, you send a query to the server who then gets back at you with the relevant information. That is a simple client-server.
Now, centralized systems have treated us well for many years, however, they have several vulnerabilities.
Firstly, because they are centralized, all the data is stored in one spot. This makes them easy target spots for potential hackers.
If the centralized system were to go through a software upgrade, it would halt the entire system
What if the centralized entity somehow shuts down for whatever reason? That way nobody will be able to access the information that it possesses
Worst case scenario, what if this entity gets corrupted and malicious? If that happens then all the data that is inside the blockchain will be compromised.
So, what happens if we just take this centralized entity away?
In a decentralized system, the information is not stored by one single entity. In fact, everyone in the network owns the information.
In a decentralized network, if you wanted to interact with your friend then you can do so directly without going through a third party. That was the main ideology behind Bitcoins. You and only you alone are in charge of your money. You can send your money to anyone you want without having to go through a bank.
Blockhcain technology: new networks
Pillar #2: Transparency
One of the most interesting and misunderstood concepts in blockchain is “transparency.” Some people say that blockchain gives you privacy while some say that it is transparent. Why do you think that happens?
Well… a person’s identity is hidden via complex cryptography and represented only by their public address. So, if you were to look up a person’s transaction history, you will not see “Bob sent 1 BTC” instead you will see “1MF1bhsFLkBzzz9vpFYEmvwT2TbyCt7NZJ sent 1 BTC”.
The following snapshot of Ethereum transactions will show you what we mean:
Ethereum transactions
So, while the person’s real identity is secure, you will still see all the transactions that were done by their public address. This level of transparency has never existed before within a financial system. It adds that extra, and much needed, level of accountability which is required by some of these biggest institutions.
Speaking purely from the point of view of cryptocurrency, if you know the public address of one of these big companies, you can simply pop it in an explorer and look at all the transactions that they have engaged in. This forces them to be honest, something that they have never had to deal with before.
However, that’s not the best use-case. We are pretty sure that most of these companies won’t transact using cryptocurrency, and even if they do, they won’t do ALL their transactions using cryptocurrency. However, what if the blockchain was integrated…say in their supply chain?
You can see why something like this can be very helpful for the finance industry right?
Pillar #3: Immutability
Immutability, in the context of the blockchain, means that once something has been entered into the blockchain, it cannot be tampered with.
Can you imagine how valuable this will be for financial institutes?
Imagine how many embezzlement cases can be nipped in the bud if people know that they can’t “work the books” and fiddle around with company accounts.
The reason why the blockchain gets this property is that of the cryptographic hash function.
In simple terms, hashing means taking an input string of any length and giving out an output of a fixed length. In the context of cryptocurrencies like bitcoin, the transactions are taken as input and run through a hashing algorithm (Bitcoin uses SHA-256) which gives an output of a fixed length.
Let’s see how the hashing process works. We are going to put in certain inputs. For this exercise, we are going to use the SHA-256 (Secure Hashing Algorithm 256).
hashing
As you can see, in the case of SHA-256, no matter how big or small your input is, the output will always have a fixed 256-bits length. This becomes critical when you are dealing with a huge amount of data and transactions. So basically, instead of remembering the input data which could be huge, you can just remember the hash and keep track.
A cryptographic hash function is a special class of hash functions that has various properties making it ideal for cryptography. There are certain properties that a cryptographic hash function needs to have in order to be considered secure. You can read about those in detail in our guide on hashing.
There is just one property that we want you to focus on today. It is called the “Avalanche Effect.”
What does that mean?
Even if you make a small change in your input, the changes that will be reflected in the hash will be huge. Let’s test it out using SHA-256:
blockchain hashing
Do you see that? Even though you just changed the case of the first alphabet of the input, look at how much that has affected the output hash. Now, let’s go back to our previous point when we were looking at blockchain architecture. What we said was:
The blockchain is a linked list that contains data and a hash pointer that points to its previous block, hence creating the chain. What is a hash pointer? A hash pointer is similar to a pointer, but instead of just containing the address of the previous block it also contains the hash of the data inside the previous block.
This one small tweak is what makes blockchains so amazingly reliable and trailblazing.
Imagine this for a second, a hacker attacks block 3 and tries to change the data. Because of the properties of hash functions, a slight change in data will change the hash drastically. This means that any slight changes made in block 3, will change the hash which is stored in block 2, now that in turn will change the data and the hash of block 2 which will result in changes in block 1 and so on and so forth. This will completely change the chain, which is impossible. This is exactly how blockchains attain immutability.

ethereum crane There is a limit to how many bitcoins can exist: 21 million. This number is supposed to be reached by the year 2140. Ether is expected to be around for a while and is not to exceed 100 million units. Bitcoin is used for transactions involving goods and services, and ether uses blockchain technology to create a ledger to trigger a transaction when a certain condition is met. Finally, Bitcoin uses the SHA-256 algorithm, and Ethereum uses the ethash algorithm.вложения bitcoin bitcoin хардфорк bitcoin casino bitcoin poloniex fee bitcoin sha256 bitcoin cryptocurrency charts bitcoin отзывы dollar bitcoin видео bitcoin bitcoin матрица bitcoin apple lamborghini bitcoin ethereum контракты casino bitcoin транзакции bitcoin bitcoin майнинга bitcoin preev bitcoin calculator cpp ethereum bitcoin 2x bitcoin trojan bitcoin red bitcoin easy bitcoin торговля кошелек bitcoin xbt bitcoin win bitcoin bitcoin оборот importprivkey bitcoin platinum bitcoin bitcoin registration bitcoin xpub bitcoin это bitcoin анимация dollar bitcoin Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2,016 blocks, or roughly every two weeks. When there is more computing power collectively working to mine for Bitcoin, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in 2009 the initial difficulty level was one. As of Nov. 2019, it is more than 13 trillion.doubler bitcoin заработок bitcoin bitcoin перспективы blockchain ethereum android tether новости monero

999 bitcoin ethereum отзывы bitcoin ann bitcoin 4000 antminer ethereum group bitcoin Proof of work and digital cash: A catch-22. You may know that proof of work did not succeed in its original application as an anti-spam measure. One possible reason is the dramatic difference in the puzzle-solving speed of different devices. That means spammers will be able to make a small investment in custom hardware to increase their spam rate by orders of magnitude. In economics, the natural response to an asymmetry in the cost of production is trade—that is, a market for proof-of-work solutions. But this presents a catch-22, because that would require a working digital currency. Indeed, the lack of such a currency is a major part of the motivation for proof of work in the first place. One crude solution to this problem is to declare puzzle solutions to be cash, as hashcash tries to do.The major difference between cryptocurrencies and fiat currencies is that cryptocurrencies are decentralized. This means that cryptocurrencies don’t have a central authority, such as a bank or government, controlling them. In a way, cryptocurrency works in a very democratic fashion: any change that needs to take place is done only after a majority of the people using the cryptocurrency agree to it.майнинг ethereum удвоить bitcoin bitcoin tm monero ann

Until recently, strong cryptography had been classified as weapons technology by regulators. In 1995, a prominent cryptographer sued the US State Department over export controls on cryptography, after it was ruled that a floppy disk containing a verbatim copy of some academic textbook code was legally a 'munition.' The State Department lost, and now cryptographic code is freely transmitted. 2 bitcoin accept bitcoin bitcoin anonymous bitcoin 3 rise cryptocurrency Bitcoin spin-off currencies such as Bitcoin Cash (BCash) and Bitcoin Gold can get a lot of buzz online and their prices can appear impressive but it's unclear if they will have any true lasting power due to the growing perception of these coins as cheap imitations of the main Bitcoin blockchain.bitcoin multisig bitcoin code розыгрыш bitcoin deep bitcoin

A blockchain is a public list of records that shows when someone transacts with cryptocurrency. Depending on the cryptocurrency, the information added to the blockchain can include information like the transaction amount. The information also can include the sender’s and recipient’s wallet addresses — a long string of numbers and letters linked to a digital wallet that stores cryptocurrency. Both the transaction amount and wallet addresses could be used to identify who the actual people using it are.4pda tether bitcoin land bitcoin что шифрование bitcoin продам ethereum bitcoin invest monero pools status bitcoin cryptocurrency calendar space bitcoin delphi bitcoin bag bitcoin bitcoin word autobot bitcoin sberbank bitcoin bitcoin security bitcoin trading bitcoin forbes bitcoin knots lite bitcoin

Although it is possible to handle bitcoins individually, it would be unwieldy to require a separate transaction for every bitcoin in a transaction. Transactions are therefore allowed to contain multiple inputs and outputs, allowing bitcoins to be split and combined. Common transactions will have either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and one or two outputs: one for the payment, and one returning the change, if any, to the sender. Any difference between the total input and output amounts of a transaction goes to miners as a transaction fee.nonce bitcoin цена ethereum bitcoin talk

People that would otherwise be saving are forced to take incremental risk because their savings are losing value. In that world, savings become financialized. And when you create the incentive not to save, do not be surprised to wake up in a world in which very few people have savings. The empirical evidence shows exactly this, and despite how much it might astound a tenured economics professor, the lack of savings induced by a disincentive to save is very predictably a major source of the inherent fragility in the legacy financial system.puzzle bitcoin bitcoin расшифровка auto bitcoin ethereum клиент bitcoin капитализация bitcoin etf tether майнинг fun bitcoin bitcoin работа bitcoin открыть ethereum аналитика dag ethereum сайт bitcoin information bitcoin сколько bitcoin loans bitcoin nicehash monero ethereum myetherwallet free bitcoin bitcoin service bitcoin видеокарты monero pro bitcoin aliexpress cryptocurrency mining ethereum проекты monero майнить подтверждение bitcoin nanopool ethereum особенности ethereum bitcoin virus electrum bitcoin blockchain ethereum
