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.

Tweaking a few variables is not going to be enough for another coin to catch up. Even adding a big feature (e.g. privacy) is likely not enough as the network effect has already created an ecosystem specific to Bitcoin.tether обменник bitcoin проверить blogspot bitcoin bitcoin matrix bitcoin co график monero ethereum asic machine bitcoin bitcoin telegram виджет bitcoin short bitcoin monero nvidia bitcoin script bitcoin fork

See Seed_phrase#Storing_Seed_Phrases_for_the_Long_Term for details.Bitcoin is a currency generated and secured by peer-to-peer networked devices that maintain a communal record of all transactions within the system that can be used in a crypto-anarchic context. The idea behind bitcoin can be traced to The Crypto Anarchist Manifesto. There exist a large number of altcoins, some of which have opaque ledgers such that transactions between peers can be untraceable (the first protocol for this is known as the Zerocoin protocol, see also Monero). Some altcoin currencies also act as decentralized autonomous organizations, or act as platforms for enabling such organizations.Fast. Transactions can be made almost as fast as data can travel over the Internet.Suppose that cryptocurrencies really take off, and in ten years, 10% of global GDP trades hands in cryptocurrencies, with half of that being in Bitcoin. At about 2% GDP growth per year, the global GDP in ten years will be about $90 trillion USD, which means $9 trillion in cryptocurrency transactions including $4.5 trillion in Bitcoin transactions per year.Two of the most popular wallets, which are also listed on Monero's official site are:cz bitcoin продать monero ethereum vk monero пулы monero client bitcoin aliexpress bitcoin pools ethereum raiden cardano cryptocurrency monero dwarfpool javascript bitcoin io tether новости bitcoin bitcoin удвоить deep bitcoin

A few extra lines of code need to be added to provide for the initial step of distributing the currency units in the first place and a few other edge cases, and ideally a function would be added to let other contracts query for the balance of an address. But that's all there is to it. Theoretically, Ethereum-based token systems acting as sub-currencies can potentially include another important feature that on-chain Bitcoin-based meta-currencies lack: the ability to pay transaction fees directly in that currency. The way this would be implemented is that the contract would maintain an ether balance with which it would refund ether used to pay fees to the sender, and it would refill this balance by collecting the internal currency units that it takes in fees and reselling them in a constant running auction. Users would thus need to 'activate' their accounts with ether, but once the ether is there it would be reusable because the contract would refund it each time.bitcoin prune pizza bitcoin ethereum получить tether обменник bitcoin loan ethereum blockchain invest bitcoin ethereum charts bitcoin динамика bitcoin cudaminer up bitcoin monero client bitcoin lurk bitcoin пул bitcoin рухнул store bitcoin bitcoin shop blocks bitcoin remix ethereum cryptocurrency monero transaction новые bitcoin ethereum получить uk bitcoin 1024 bitcoin 8 bitcoin bitcoin loan bitcoin anonymous график bitcoin bitcoin accelerator 4pda bitcoin claim bitcoin bitcoin ecdsa capitalization bitcoin bitcoin check cryptonight monero tether отзывы кости bitcoin миксер bitcoin bitcoin background faucet cryptocurrency bitcoin транзакция mikrotik bitcoin bitcoin трейдинг bitcoin check monero news currency bitcoin tether обменник bitcoin видео monero dwarfpool bitcoin monkey bitcoin simple ethereum токен ann monero faucet ethereum
