Ready? Here’s what is blockchain in simple words:
The main purpose of the blockchain is to allow fast, secure and transparent peer-to-peer transactions. It is a trusted, decentralized network that allows for the transfer of digital values such as currency and data.
Now, as we’re all newbies here. Here’s the blockchain for dummies:
Imagine the blockchain as a digital database, just like an Excel spreadsheet.
This database is typically shared across a large network containing many computers (known as “nodes”) and it is completely public. I say “typically” because it can technically be formed by any number of nodes. To get blockchain explained fully, it is important to know that the more nodes there is, the more secure it is — that’s why it’s good to have a large number of nodes running the blockchain!
Every time the network makes an update to the database, it is automatically updated and downloaded to every computer on the network.
Blockchain technology is secured with cryptographic techniques, making it near impossible for hackers to make changes to it. The only way to make changes would be to hack more than half of the nodes in the blockchain, which again, is why it is more secure to have more nodes/computers running the blockchain.
That’s your blockchain explained in simple words. So, now when someone asks you “what is blockchain?”, you have two strong answers to choose from.
How Does Blockchain Work in the Case of Bitcoin?
Bitcoin was the first cryptocurrency to use blockchain technology. It was invented by the person, or group of people, that go by the name of Satoshi Nakamoto (strangely enough, nobody knows who Satoshi Nakamoto is).
The sole purpose of Bitcoin is to act as a store of value. It allows for peer-to-peer transactions that do not need a third party, such as PayPal or a bank.
Getting Bitcoin blockchain explained is essential to understanding how blockchain works. The Bitcoin blockchain is a database (known as a “ledger”) that consists only of Bitcoin transaction records. There is no central location that holds the database, instead, it is shared across a huge network of computers. So, for new transactions to be added to the database, the nodes must agree that the transaction is real and valid.
Blockchain explained: a bank.
This group agreement is also known as a “consensus”. It occurs during the process of mining.
Note: Mining is the process in which nodes verify transactional data and are rewarded for their work. It covers their running costs (electricity and maintenance etc.) and a small profit too for providing their services. It is important to know while getting blockchain explained that it is a part of all blockchains, not just Bitcoin.
Once the nodes agree that the transaction is real, it is then added to a “block” (which is why it is called a blockchain) and is placed below the previous block of transactions in the ledger.
For a transaction to be valid, the computers on the network must confirm that:
(1) The account holds the amount of Bitcoin that the user wants to send.
(2) The amount hasn’t already been sent to someone else.
For example, let’s imagine that Tom tries to send $10 of Bitcoin to Ben. Tom only has $5 worth of Bitcoin in his wallet. Because Tom doesn’t have the funds to send $10 to Ben, this transaction would not be valid. The transaction will not be added to the ledger.
Blockchain explained: Bitcoins on a computer chip.
This means that nobody can ever spend the same money twice! This can often be a big problem for standard banks and payment systems.
A Simple Example to get Blockchain Explained Better:
Let’s compare how data is stored and shared in standard (non-blockchain) systems to how it is stored and shared in a blockchain system.
The way that traditional (non-blockchain) ledgers work is very similar to the way you would share a Microsoft Word document with your friend:
While you are editing the document, your friend is locked out and cannot make changes.
Once you have finished making your changes, you send it to your friend to edit it further.
Now while your friend is editing the document, you are locked out and cannot make changes until they are finished and send it back to you.
In a blockchain system, however, all users can view the changes while they are being made.
Blockchain explained: a blockchain.
The data is accessible in a secure and shared environment, instead of being locked to one company or person at a time (at the risk of losing the data). For example, if the data was stored on one computer and that computer was hacked or shut down, the newest version of the data would be lost.
Now, to get blockchain explained: with the blockchain, the data is stored on all the computers/nodes that run it. This means the data would not be at risk if one of the computers/nodes was hacked or broken.
As you can see, blockchain technology does not just benefit cryptocurrencies. It benefits many different industries. Imagine the amounts of legal, health, accounts and customer data, etc. that should be used this way.
This is just one of the many advantages of blockchain technology! Now, let’s look at some of the others.

Every day, hundreds of millions of low-income people go to work in hard jobs in foreign countries to make money to send back to their families in their home countries – over $400 billion in total annually, according to the World Bank. Every day, banks and payment companies extract mind-boggling fees, up to 10 percent and sometimes even higher, to send this money.They can be affected by gapping: market volatility can cause prices to move from one level to another without actually passing through the level in between. Gapping (or slippage) usually occurs during periods of high market volatility. As a result, your stop-loss could be executed at a worse level than you had requested. This can worsen losses if the market moves against you.логотип bitcoin neo bitcoin

However, Szabo did not propose a mechanism for limiting the total units of bit gold, but rather envisioned that units would be valued differently based upon the amount of computational work performed to create them.simple bitcoin ethereum хешрейт ethereum rig ethereum fork alipay bitcoin tracker bitcoin bitcoin daily краны monero click bitcoin ethereum эфириум ico cryptocurrency finney ethereum coffee bitcoin обвал ethereum japan bitcoin bitcoin трейдинг

Some miners use application-specific integrated circuits (ASICs) for PoW. This trend toward mining pools and specialized ASICs has made mining some cryptocurrencies economically infeasible for most players without access to the latest ASICs, nearby sources of inexpensive energy, or other special advantages.greenaddress bitcoin bitcoin tools bitcoin tx testnet ethereum ethereum io bitcoin продам новости monero monero график сборщик bitcoin bitcoin ваучер bitcoin security iso bitcoin заработок bitcoin bitcoin 10 доходность bitcoin bitcoin captcha

The Difficulty MetricIn order to get started mining, cryptocurrency miners will need dedicated computer hardware with a specialized graphical processing unit (GPU) chip or application-specific integrated circuit (ASIC), sufficient cooling means for the hardware, an always-on internet connection, a legitimate cryptocurrency mining software package, and membership in both an online cryptocurrency exchange as well as an online mining pool.british bitcoin ethereum coins

bitcoin пирамида The difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. The rate is recalculated every 2,016 blocks to a value such that the previous 2,016 blocks would have been generated in exactly one fortnight (two weeks) had everyone been mining at this difficulty. This is expected yield, on average, one block every ten minutes.etf bitcoin hacking bitcoin The issue that many investors run into is that it can be difficult to find a custodian that accepts bitcoin in an IRA.

The Ethereum white paper published by Ethereum creator Vitalik Buterin in 2013 splits dapps into three main types:maps bitcoin There has been much talk about Bitcoin within libertarian and economic circles. It’s becoming a buzzword, but like all new systems that break onto the public stage quickly, Bitcoin brings with it excitement, speculation, rumor, and downright confusion. To be sure, Bitcoin is complicated. After all, it’s an entirely new global monetary system — both a currency and a payment network for that currency.InterPlanetary File System (IPFS) makes it easy to conceptualize how a distributed web might operate. Similar to the way a BitTorrent moves data around the internet, IPFS gets rid of the need for centralized client-server relationships (i.e., the current web). An internet made up of completely decentralized websites has the potential to speed up file transfer and streaming times. Such an improvement is not only convenient. It’s a necessary upgrade to the web’s currently overloaded content-delivery systems.q bitcoin bitcoin s bitcoin курс пулы bitcoin daemon monero flash bitcoin майнинга bitcoin Separately, anyone within or outside the network could copy bitcoin’s software to create a new version of bitcoin, but any units created by such a copy would be considered invalid by the nodes operating within the bitcoin network. Any subsequent copies or units would not be considered valid, nor would anyone accept the currency as bitcoin. Each bitcoin node independently validates whether a bitcoin is a bitcoin, and any copy of bitcoin would be invalid, as it would not have originated from a previously valid bitcoin block. It would be like trying to pass off monopoly money as dollars. You can wish it to be money all you want, but no one would accept it as bitcoin, nor would it share the emergent properties of the bitcoin network. Running a bitcoin full node allows anyone to instantly assay whether a bitcoin is valid, and any copy of bitcoin would be immediately identified as counterfeit. The consensus of nodes determines the valid state of the network within a closed-loop system; anything that occurs beyond its walls is as if it never happened.In the past many people have accidentally lost bitcoins because of failed backups, mistyped letters, forgotten hard drives, corrupted SSD devices, or numerous other slip ups.майнить bitcoin bitcoin dance bitcoin команды panda bitcoin bitcoin land rotator bitcoin ethereum пулы форум bitcoin bitcoin galaxy bitcoin мониторинг usd bitcoin bitcoin значок bitcoin майнинга bitcoin 2017
