What is blockchain?
Blockchain: Blockchain is a shared, non-convertible log that performs the process of recording transactions and tracking assets in a business network. Property can be intangible (house, car, money, land) or intangible (intellectual property, copyright, copyright, marking). Almost anything with value can be tracked and sold on a blockchain network, reducing risk and reducing costs for all involved.
SIMPLY,
Blockchain is a distributed site that is shared between computer network nodes. As a database, blockchain stores information electronically in a digital format. Blockchains are best known for their important role in cryptocurrency systems, such as Bitcoin, by keeping a secure and separate record of transactions. The innovation of blockchain is that it ensures the integrity and security of the data record and creates trust without the need for a trusted third party.
One important difference between a standard website and a blockchain is the way data is structured. Blockchain collects information together in groups, known as blocks, that capture information sets. Blocks have some storage capacity and, when completed, are closed and connected to a pre-filled block, forming a series of data known as blockchain. All new information following that newly installed block is integrated into a newly constructed block which will be added to the series once completed.
A website usually organizes its data into tables, while a blockchain, as its name implies, organizes its data into fragments (blocks) grouped together. This data structure naturally creates an irreversible timeline of data when used in a split case. When the block is filled, it is placed on a stone and becomes part of this timeline. Each block in the chain is given a specific time stamp when added to the chain.
Why blockchain is important:
Business is driven by information. The sooner it is found and the more accurate it is, the better. Blockchain is ready to deliver that information because it provides fast, shared and completely transparent information stored in a static manual that can only be accessed by authorized network members. The blockchain network can track orders, payments, accounts, production and much more. And because members have one true vision, you can see all the details of the action from end to end, giving you great confidence, as well as new efficiency and opportunities.
As each transaction occurs, it is written as a “block” of data
That transaction reflects the movement of tangible (product) or intangible (intelligent) assets. The data block can record the information you choose: who, what, when, where, how much and even the situation - such as food delivery temperature.
Each block is connected to the front and back of it
These blocks form a series of data as the property moves from one location to another or ownership changes hands. Blocks ensure precise timing and sequence of transactions, and blocks connect securely to prevent any block from being aligned or blocking between two existing blocks.
Activity is blocked together in an unstoppable series: blockchain
Each additional block strengthens the validity of the previous block and therefore the entire blockchain. This provides a blockchain tamper-transparent, delivering significant static power. This eliminates the possibility of interrupting the malicious character - and creates a workbook for you and other network members you can trust.
What needs to be changed: Tasks often waste effort in keeping duplicate records and third-party verification. Record keeping systems can be vulnerable to cybercrime and cyberbullying. Exposure to this limit may delay data verification. And with the advent of IoT, commodity prices exploded. All of this delays business, eliminates policy - and means we need a better way. Log in to blockchain.
Great trust
With blockchain, as a member only network member, you can be sure that you get accurate and timely data, and that your private blockchain records will be shared only with members of the network to whom you have given direct access.
Great security
Data accuracy is required for all network members, and all verified functions are not changed because the recording is permanent. No one, not even a system administrator, can delete a task.
More performance
With a distributed ledger assigned to network members, the reconciliation of time-wasting records is removed. And to speed up the transaction, a set of rules - called a smart contract - can be stored in the blockchain and executed automatically.
Blockchain is a type of shared database that differs from a general website in the way it stores information; blockchains store data in blocks and are then linked together via cryptography. As new data enters, it is added to the new block. Once a block is filled with data, it is tied to the previous block, causing the data to be grouped together in chronological order. Different types of information can be stored in the blockchain, but the most common use to date has been as a transaction book. In the case of Bitcoin, the blockchain is used in isolation so that no one person or group has the power to control it — instead, all users in general retain control. The suspended blockchains are invalid, meaning that the inserted data cannot be undone. With Bitcoin, this means that transactions are permanently recorded and visible to
anyone.

Why is there so much hype surrounding blockchain technology?
There have been many attempts to make digital money in the past, but it has always failed.
The problem is trust. When someone creates a new currency called the X dollar, how can we trust that they will not give you X million dollars, or steal your X dollars?
Bitcoin is designed to solve this problem using a type of data called blockchain. Most common data, such as the SQL website, has an administrator who can change entries (e.g., donate X million). Blockchain is different because no one is in control; it is run by the people who use it. In addition, bitcoins cannot be fraudulent, fraudulent or double-used - so people who own these currencies can hope to have some value.
NOW,
Is Blockchain Secure?
Blockchain technology achieves the security and trust that is shared by people in many ways. First, new blocks are always kept in order and in chronological order. That is, they are not always heard at the "end" of the blockchain. After a block is added at the end of the blockchain, it is very difficult to go back and change the contents of the block unless most of the network has reached an agreement to do so. This is because each block contains its own hash, with the block hash before it, and the time stamp specified earlier. Hash codes are created by a mathematical function that converts digital information into a series of numbers and letters. If that information is organized in any way, the hash code also changes.
Suppose a hacker, who also uses a node in a blockchain network, wants to change the blockchain and steal cryptocurrency from everyone. If they changed one copy of their copy, they would no longer share the same copy with everyone else. When everyone else points to their copies, they will see this one copy stand out, and the translation of that chain will be discarded as illegal.
Succeeding at such a hack would require the hacker to simultaneously control and modify 51% or more of the blockchain so that their new copy would be a multiple copy and, thus, an agreed chain. Such an attack will also require a large amount of money and resources, as they will have to redo all the blocks as they will now have different time stamps and hash codes.
Due to the size of many cryptocurrency networks and their rapid growth, the cost of issuing such an action is unlikely to be negligible. This will not only be more expensive but also less productive. Doing such a thing would not go unnoticed, as network members would see such big changes in the blockchain. Members of the network will then be hard pressed to a new version of the untouched chain. This can cause the attacked version of the token to decrease in value, making the attack less meaningful, as the bad character has control over useless assets. The same thing will happen if a bad character can attack a new Bitcoin fork. It is designed in such a way that participation in the network is more economically motivated than attacked.
Bitcoin vs. Blockchain
Blockchain technology was first introduced in 1991 by Stuart Haber and W. Scott Stornetta, two researchers who wanted to use a system where text time stamps could not be interrupted. But it was not until almost two decades later, when Bitcoin was launched in January 2009, that blockchain had its first real-world application.
The Bitcoin protocol is built on the blockchain. In a research paper introducing a digital currency, anonymous Bitcoin creator, Satoshi Nakamoto, called it "a new peer-to-peer electronic financial system, with no third party to trust."
The important thing to understand here is that Bitcoin simply uses the blockchain as a way to explicitly record a payment book, but the blockchain, in theory, can be used to consistently record any number of data points. As discussed above, this could be in the form of transactions, votes in elections, product lists, status identification, real estate titles, and more.
Currently, tens of thousands of projects are looking to use blockchains in a variety of ways to help the community other than just recording transactions - for example, as a safe way to vote in democratic elections. The nature of the blockchain consistency means that fraudulent voting will be much harder to make. For example, the voting system could work in such a way that each citizen of the country would be given one cryptocurrency or token. Each candidate will be given a specific fund address, and voters will send their token or crypto to the address of any candidate they wish to vote for. The transparent and predictable environment of the blockchain will eliminate both the need to count the votes of the people and the ability of the bad characters to disrupt physical votes.
