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.

The music you buy could even be encoded in the blockchain itself, making it a cloud archive for any song purchased. Because the amounts charged can be so small, subscription and streaming services will become irrelevant.nova bitcoin bitcoin кредит bitcoin сети bitcoin презентация bitcoin gold wallets cryptocurrency ethereum code bitcoin car bitcoin bitcoin сделки ethereum 2017 bitcoin cny калькулятор bitcoin

The first category is financial applications, providing users with more powerful ways of managing and entering into contracts using their money. This includes sub-currencies, financial derivatives, hedging contracts, savings wallets, wills, and ultimately even some classes of full-scale employment contracts. The second category is semi-financial applications, where money is involved but there is also a heavy non-monetary side to what is being done; a perfect example is self-enforcing bounties for solutions to computational problems. Finally, there are applications such as online voting and decentralized governance that are not financial at all.600 bitcoin bitcoin луна bitcoin london bitcoin блог carding bitcoin korbit bitcoin analysis bitcoin bitcoin футболка сети bitcoin mine ethereum bitcoin rotator exchange monero bitcoin rotator bitcoin faucet криптовалюта tether ethereum падает bitcoin порт bitcoin теория forum ethereum 1080 ethereum airbit bitcoin bitcoin keywords buy tether view bitcoin bitcoin 9000 wikipedia ethereum demo bitcoin bitcoin кран bitcoin crash cudaminer bitcoin
bitcoin funding Adoption as a World Reserve Currency - Eventually all transactions will be settled on the blockchain, including house titles, stock purchases, car titles, and other monetary instruments and currencies. Network effects one through six culminate in this final network effect. Any newcomer in the realm of cryptocurrency or traditional currency, for that matter; would need to beat Bitcoin in all seven of these areas. This is unlikely considering the pace of development in Bitcoin Core, the level of investment in Bitcoin companies around the world, the growth in Bitcoin's user base, and on and on; Further price increases will only accelerate the process. Finally, a speculative attack could dramatically boost the value of Bitcoin almost overnight.bitcoin puzzle

It was introduced by a London-based company which offered the security of a bank vault for securing the keys of bitcoin wallets. This service is insured by an underwriter thus providing protection against theft or loss of bitcoins. This service has a drawback as it requires the identity and address proof of the person seeking the service. This tends to dissuade those who want to be anonymous owners from availing the service. The custody service by Elliptic Vault is an example of a deep cold storage.What Is Cold Storage For BitcoinThe invention of distributed ledgers represents a revolution in how information is gathered and communicated. It applies to both static data (a registry), and dynamic data (transactions). Distributed ledgers allow users to move beyond the simple custodianship of a database and divert energy to how we use, manipulate and extract value from databases — less about maintaining a database, more about managing a system of record.s bitcoin bitcoin china nova bitcoin ethereum 4pda установка bitcoin кошелек monero cubits bitcoin bitcoin balance

Under the new guidelines, 'a user of virtual currency is not a Money Services Businesses (MSB) under FinCEN's regulations and therefore is not subject to MSB registration, reporting, and record keeping regulations.' Miners, when mining bitcoins for their own personal use, aren't required to register as a MSB or Money Transmitter. bitcoin poker bitcoin lurkmore

IOTA uses a DLT called the Tangle. Miners don’t confirm new transactions, users do...When a user wants to make a payment using the Tangle they have to verify and confirm two other user’s transactions first. Only then will their payment be processed. It’s like getting students to grade each other’s homework instead of the teacher doing it. The Tangle is thought to be a lot faster than Bitcoin, Litecoin and Ethereum! If you thought that was weird, check this out — IOTA isn’t even designed to be used by humans! It’s designed for the Internet of Things. That’s any machine with an internet connection. IOTA will help the IoT communicate with itself. IOTA actually means the Internet of Things Application. Imagine that! In the future, your driverless car will use IOTA to go to the gas station, fill up with gas and pay. All without any humans being involved.bitcoin drip polkadot stingray bitcoin virus bitcoin advcash программа ethereum bitcoin synchronization bitcoin комментарии bitcoin signals bitcoin займ cgminer ethereum инвестиции bitcoin bitcoin torrent
