What is Blockchain?
It’s one of the most puzzling questions we find ourselves trying to answer when first discovering cryptocurrencies. So getting blockchain explained is essential.
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.

He theorized this behavior was rational, and was aimed at reducing transaction costs.

bitcoin office 2 bitcoin convert bitcoin To stop people cheating the network, a system known as 'proof-of-work' is used. Proof-of-work is needed before any group (block) of transactions is added to the blockchain. When the computers are performing their proof-of-work, what they’re doing is trying to guess a long string of numbers and letters. This string is known as a hash. The Bitcoin cryptocurrency has a cryptographic proof-of-work hash function - SHA 256d. It is a standard mathematical algorithm that converts inputs into outputs. Usually, it is really computationally-easy to get the output by putting the input into the function. E.g. from 1+2+3+4 we get 10. But if we set the challenge vice versa knowing only the output we will have a number of different variants of inputs: 9+1, 8+2, 7+3, 6+4, 5+5, etc. The challenge in a mathematical puzzle is that miner needs to find such input that will satisfy the specific output.loan bitcoin kinolix bitcoin компания bitcoin пулы bitcoin обновление ethereum сервисы bitcoin icon bitcoin bitcoin перспективы bitcoin gadget ethereum course vk bitcoin bitcoin wmx смесители bitcoin ethereum pool bitcoin автоматом vector bitcoin bitcoin neteller iso bitcoin bitcoin half bitcoin шахта bitcoin установка bitcoin майнер direct bitcoin ethereum майнер bitcoin cc рынок bitcoin форк bitcoin ann bitcoin часы bitcoin Blockchain gives the facility to verify and audit transactions by multiple supply chain partners involved in the supply chain management system.

monero pool bitcoin tm bitcoin withdrawal india bitcoin Bitcoin is a digital bearer instrument. It is a way to exchange money or assets between parties with no pre-existing trust: A string of numbers is sent over email or text message in the simplest case. The sender doesn’t need to know or trust the receiver or vice versa. Related, there are no chargebacks — this is the part that is literally like cash – if you have the money or the asset, you can pay with it; if you don’t, you can’t. This is brand new. This has never existed in digital form before.Be it governments, businesses, or non-profit agencies; record management is often cumbersome and frustrating. Errors and lack of accuracy are common in record-keeping when humans do it.
