Blockchain technology is simply defined as a decentralized, distributed account that records the emergence of a digital asset. With the underlying design, the data of a blockchain technology cannot be changed, which makes it a legitimate disruption to industries such as payroll, cyber security and healthcare. In today's article I will tell you what blockchain technology is, how it works and other important information about it.

What is Blockchain Technology
Blockchain technology is a shared, unalterable ledger that simplifies the process of recording transactions and tracking assets across a business network. An asset can be real (a house, car, cash, land) or implicit (intellectual property, patent, copyright, branding). In a blockchain technology virtually anything of value can be tracked and traded, reducing risk and reducing costs for all involved.
A blockchain is a distributed database that is shared between nodes in a computer network. As a database, a Blockchain Technology stores information electronically in digital format. Blockchain technologies are best known for their important role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The invention of a blockchain is that it guarantees the reliability and security of data records and builds trust without the need for a trusted third party.

Blockchain technology, sometimes known as Distributed Laser Technology (DLT), makes the history of any digital asset unalterable and transparent through decentralization and the use of cryptographic hashing. A simple analogy to understanding blockchain technology is a Google Doc.
When we create a document and share it with a group of people, the document is distributed instead of copied or transferred. This creates a decentralized distribution chain that gives everyone access to documents at the same time.
Moreover
On the other hand, no one is locked out waiting for a change, while all changes in the document are recorded in real-time, making the changes completely transparent. Of course, blockchain technology is more complex than a Google Doc, but the analogy is appropriate because it illustrates three critical concepts of technology: Blockchain is a particularly promising and revolutionary technology because it helps reduce risk, stop fraud and bring transparency in a measurable way for countless uses.
One of the main differences between a typical database and blockchain technology is how the data is structured. A blockchain collects information together in a group, known as a block, which holds a set of information.
Blocks have a fixed storage capacity and, when filled, are closed and linked to a pre-filled block, forming a chain of data known as a blockchain. The newly added block follows that all new information is compiled into a newly formed block which, once completed, will also be added to the chain.
A database usually forms its data into tables, where a blockchain technology , as its name implies, forms its data into blocks that are aggregated. When applied in a decentralized nature, this data structure inherently creates an irreversible timeline of data.
When a block is filled, it is set in stone and becomes a part of this timeline. Each block of the chain is given an exact time stamp when it is added to the chain.
How blockchain works
Blockchain technology consists of blocks, nodes and minors. Each chain consists of multiple blocks and each block has three basic elements:
Block data
A 32-bit integer called a nonce. Nons are created randomly when a block is created, which then creates a block header hash.
A hash is a 256-bit number associated with a nuns. It must start with a huge number of zeros (that is, be extremely small). When the first block of a chain is created, a nuance creates a cryptographic hash. Block data is considered to be signed and is permanently bound with nuns and hashes unless it is mined.
Minors
Minor Ra creates new blocks in the chain through a process called mining. Each block in a blockchain has its own unique nuances and hashes, but also refers to the hash of the previous block in the chain. Minor RA uses specialized software to solve incredibly complex math problems by finding a nuance that creates a recognized hash.
Because the nuns are only 32 bits and the hash is 256. There are approximately four billion possible non-hash combinations that must be mined before finding the right one.
To change any block before the chain, not only the block with the change, but all subsequent blocks must be re-excavated. This is why blockchain technology is so difficult to manipulate.
Think of it as "mathematical security" since finding the golden nuances requires a lot of time and computing power. When a block is successfully mined, the change is accepted by all nodes in the network and the mine is financially rewarded.
Node
Decentralization is one of the most important concepts in blockchain technology . No computer or organization can own a chain. Instead, it is a distributed register through nodes connected to a chain. Nodes can be any type of electronic device that maintains a copy of the blockchain and keeps the network running.
Each node has its own copy of the blockchain technology , and the network must algorithmically approve newly excavated blocks for chain updates, reliability, and verification.
Since the blockchains are transparent, every action of the laser is easily checked and observed. Each participant is given a unique alphanumeric identification number to view their transactions.
Combining public information with a check-and-balance system helps blockchain maintain integrity and build trust among users. Basically, blockchain can be thought of as a measure of trust through technology.
Other methods:
First proposed as a research project in 1991, the blockchain concept preceded its first widespread application: Bitcoin, in 2009. Since then, the use of blockchain has exploded with the creation of various cryptocurrencies, decentralized money (DeFi) applications, non-fungible tokens (NFTs), and smart contracts.
Blockchain decentralization
Imagine that a company has a server firm with 10,000 computers that are used to maintain a database that contains all of the client's account information. The company owns a warehouse building where all these computers are under one roof and has complete control over each of these computers and all the information contained in them. This, however, provides a single point of failure.
What will happen if the power goes out in that place? What if his internet connection is disconnected? What if it burns to the ground? What if someone deletes everything with a single keystroke? In any case, the information may be lost.
What a blockchain technology does is allow the data in that database to be spread across different network nodes in different places. This not only creates redundancy but also maintains the integrity of the data stored in it - if someone tries to change a record in an instance of the database, the other nodes will not be changed and thus prevent a bad actor from doing it.
If a user tampers with the Bitcoin transaction record, all other nodes will cross-reference each other and easily identify the node with incorrect information. This system helps to establish an accurate and transparent sequence of events. Thus, no single node in the network can change the information contained in it.
For this reason, data and history (such as a cryptocurrency transaction) are unchangeable. A record of this type may be a list of transactions (such as with a cryptocurrency), but it is also possible for a blockchain technology to hold various information, such as a legal contract, state identification, or company inventory.
Transparency
Due to the decentralized nature of Bitcoin's blockchain, all transactions can be viewed transparently by having a private node or using Blockchain Explorer, allowing anyone to view transactions directly. Each node has its own copy of the chain which is updated as new blocks are confirmed and added. This means that if you want, you can track Bitcoin wherever it goes.
For example, exchanges have been hacked in the past, where those who kept bitcoin exchanges have lost everything. Although hackers can be completely anonymous, the bitcoins they have extracted are easily found. The stolen bitcoins in these hacks will be known if they are moved or spent somewhere.
Of course, the records stored in the Bitcoin blockchain (as well as most others) are encrypted. This means that only the owner of a record can decrypt it to reveal their identity (using a public-private key pair). As a result, users of blockchain technology may remain anonymous while maintaining transparency.
How is blockchain used?
As we now know, Bitcoin's blockchain store data blocks are about financial transactions. Today, there are more than 10,000 other cryptocurrency systems running on the blockchain But it turns out that blockchain is actually a reliable way to store data about other types of transactions.
Some companies that have already incorporated blockchain technology include Walmart, Pfizer, AIG, Siemens, Unilever and many more. For example, IBM has created its food trust blockchain to track the journey that food products take to reach their destination.
These companies can now see everything else they come in contact with, so that problem identification can happen sooner and potentially save lives. This is an example of blockchain in practice, but there are many other forms of blockchain technology implementation.
In banking and finance
Probably no industry could be more profitable than banking by integrating blockchain technology with its business activities. Financial institutions operate only during business hours, usually five days a week.
That means if you try to deposit a check at 6pm on Friday, you'll probably have to wait until Monday morning for that money to hit your account. Even if you deposit your deposit within the business period, banks may still take one to three days to verify the transaction due to the total amount of transactions that need to be disposed of. Blockchain, on the other hand, never sleeps.
By integrating blockchain into banks, customers can see their transactions processed within 10 minutes - basically the time it takes to add a block to the blockchain, regardless of the holiday or day or week.
Through blockchain, banks have the opportunity to exchange funds between institutions more quickly and securely. In a stock trading business, for example, the settlement and clearing process can take up to three days.
Coin
Blockchain technology forms the basis of cryptocurrencies like Bitcoin. The US dollar is regulated by the Federal Reserve. Under this central authority system, a user's data and currency are technically at the discretion of their bank or government.
If a user's bank is hacked, the client's personal information is at risk. If the client's bank breaks down or the client lives in a country with an unstable government, the value of their currency may be at risk. In 2006, a number of failed banks were granted bail - partly using taxpayer money. These are the concerns from which Bitcoin was first captured and developed.
By spreading its activities across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for central authority. This not only reduces the risk but also eliminates a lot of processing and transaction fees.
It can offer more stable currencies and a wider network of individuals and organizations with which they can do business, both domestically and internationally, with more applications in countries with volatile currencies or financial infrastructure.
Healthcare
Healthcare providers can use blockchain to securely store their patients' medical records. When a medical record is created and signed, it can be written on the blockchain, providing patients with evidence and confidence that the record cannot be changed.
These personal health records can be encoded and stored using blockchain technology with a private key , so that they are only accessible to certain individuals, thus ensuring privacy.
Property records
If you have ever spent time in your local recorder's office, you know that the process of recording property rights is both understandable and inefficient. Today, a physical document must be delivered to a government employee at the local recording office, where it is entered manually into the county's central database and public index. In the case of property disputes, property claims must be matched with the public index.
This process is not only costly and time-consuming-it is also prone to human error, where each impurity makes property ownership tracking less efficient. Blockchain technology has the potential to eliminate the need to scan documents and track physical files at a local recording office.
If the ownership of the property is preserved and verified in the blockchain, the owners can trust that their deeds have been accurately and permanently recorded.
Smart deal
A smart contract is a computer code that can be used to create blockchain technology to facilitate, verify, or negotiate a contract.Smart contracts work under a condition that users agree to.When these conditions are met, the terms of the contract are automatically fulfilled.
Supply chain
Like the IBM Food Trust example, suppliers can use blockchain technology to record the source of their purchases. This allows companies to not only verify the authenticity of their products but also verify common labels such as "organic," "local," and "fair trade." According to Forbes, the food industry is increasingly adopting blockchain technology to track farm-to-user journeys and food safety .
Vote
Blockchain technology can be used to facilitate a modern voting system. Voting through blockchain technology carries the potential to eliminate electoral fraud and increase voter turnout, as tested in the November 2016 midterm elections in West Virginia.
Using blockchain technology will make it almost impossible to manipulate the vote. Blockchain technology protocols will maintain transparency in the electoral process, reduce the staff required to conduct elections, and provide almost immediate results.
Finally
The goal of blockchain technology is to allow digital information to be recorded and distributed, but not edited. In this way, a blockchain technology is the basis of immutable lasers, or records of transactions that cannot be changed, deleted or destroyed. For this reason blockchains are also known as a Distributed Laser Technology (DLT).
