What is Blockchain Technology?
In its simplest form, the blockchain is the technology that allows people to send and receive cryptocurrencies such as Bitcoin. However, it is far more than just a payments system. When Satoshi Nakamoto created the world’s first ever cryptocurrency (Bitcoin), he also created an amazing protocol known as the blockchain.

The most interesting part to the blockchain is that no single person or authority has control over it. Instead, transactions are verified and confirmed by the online community, which makes it decentralized! The protocol has lots and lots of benefits such as transparency, speed and security, which I will explain in more detail later on.
The actual idea of blockchain technology is not only linked to financial transactions, as it has the potential to be applied to just about any industry!
As the blockchain is decentralized, everybody has access to the same data (unless it is a private blockchain used by companies). That means that as soon as a transaction is processed and confirmed, it appears on the blockchain for all to see.
This is very similar to a real-world accounting ledger, where the company accountant can view every transaction that has ever occurred, along with account balances. However, as blockchains such as Bitcoin and Ethereum are public, anyone can view the transactional data.
There is so much to talk about when trying to understand the correct blockchain definition, so I thought it would be best to break everything down. The next part of my “What is Blockchain” guide is going to talk about why it is called blockchain!
Blockchain Definition: Why is it Called Blockchain?
Although there are now many different versions of the blockchain definition, they all work in very similar ways. The easiest way to explain what it does is to split the word blockchain into two – block and chain!
Think about a real-world container that carries lots of boxes from destination A to destination B. In the world of cryptocurrency, the container is the “block” and each box that is on the container is an individual transaction.
“Container” = Block
“Boxes” = Transactions
“The container carries lots of boxes” = The Block Carries Lots of Transactions
I know this might sound complex, but stay with me as it is all about to make sense! So, in the example of the blockchain Bitcoin uses, it takes a total of 10 minutes for one block of transactions to be confirmed on the network.
Like in a real-world container, there is only a certain amount of transactions that the block can carry, which is determined by the maximum block size. Every blockchain has its own maximum block size, which is normally the amount of data (megabytes) it can hold.
Bitcoin is able to hold the 1MB worth of data in each block, while others, such as Bitcoin Cash, have a block size limit of 8MB.
The larger the block size limit, the more transactions it can hold. So now you know what a block is, what about the chain?
To make things really easy for you, I am going to stick with the example of a container carrying boxes! Let’s imagine that the container has reached its first destination. That means the block has been confirmed and it is now available on the public ledger for all to see.
However, the container is ready to depart for its next destination. Every new or old box (transactions) that the container (block) carries will also be available to view on the public blockchain. This is the same for every single transaction. As soon as it is confirmed, the transaction data is clear for everybody to see, which is why it is called a “chain” of transactions!

How? The smart contract is linked to the database recording flight status. The smart contract is created based on terms and conditions.Public Blockchain ledgers are visible to all the users on the internet and any user can verify and add a block of transactions to the Blockchain.

Users don’t need to have a bank account!bitcoin cny Merkle trees. Bitcoin uses essentially the data structure in Haber and Stornetta's 1991 and 1997 papers, shown in simplified form in Figure 2 (Nakamoto was presumably unaware of Benaloh and de Mare's work). Of course, in bitcoin, transactions take the place of documents. In each block's Merkle tree, the leaf nodes are transactions, and each internal node essentially consists of two pointers. This data structure has two important properties. First, the hash of the latest block acts as a digest. A change to any of the transactions (leaf nodes) will necessitate changes propagating all the way to the root of the block, and the roots of all following blocks. Thus, if you know the latest hash, you can download the rest of the ledger from an untrusted source and verify that it has not changed. A similar argument establishes another important property of the data structure—that is, someone can efficiently prove to you that a particular transaction is included in the ledger. This user would have to send you only a small number of nodes in that transaction's block (this is the point of the Merkle tree), as well as a small amount of information for every following block. The ability to efficiently prove inclusion of transactions is highly desirable for performance and scalability.bitcoin стоимость finex bitcoin
