If you want to pay online, you must save an account and provide information on the credit card. If you don’t have a credit card, you can pay with a bank transfer. With the rise of cryptocurrencies, these methods can become old.
Imagine a world in which you can carry out transactions and many other things without having to give your personal information. A world in which you no longer need to count on banks or governments. It sounds incredible, right? This is exactly what blockchain technology allows us to do.
It’s like your computer’s hard drive. Blockchain is a technology that allows you to store data in digital blocks, which are connected together as links in a chain.
Blockchain technology was initially invented in 1991 by two mathematicians, Stuart Haber and W. Scot Stornetta. They first proposed the system to ensure that the time -tootting could not be falsified.
A few years later, in 1998, the developer of software Nick Szabo proposed to use a similar type of technology to secure a digital payment system which he called “Bit Gold”. However, this innovation was not adopted before Satoshi Nakamoto invented the first blockchain and Bitcoin.
So what is the blockchain?
A blockchain is a distributed database shared between the nodes of a computer network. It records information in digital format. Many people have heard of blockchain technology when they started looking for information about Bitcoin.
Blockchain is used in cryptocurrency systems to ensure secure and decentralized transactions recordings.
The blockchain allowed people to guarantee the loyalty and security of a data file without the need for a third party to guarantee accuracy.
To understand how a blockchain works, consider these basic steps:
- The blockchain collects information in “blocks”.
- A block has a storage capacity, and once it is used, it can be closed and linked to a previously served block.
- The blocks form chains, which are called “blockchains”.
- More information will be added to the block with the most content until its capacity is full. The process is repeated.
- Each chain block has an exact horoding and cannot be changed.
Let’s learn to know more about the blockchain.
How does the blockchain work?
Blockchain saves digital information and distributes it on the network without modifying it. The information is divided between many users and stored in an unchanging and permanent register which cannot be modified or destroyed. This is why the blockchain is also called “distributed big book technology” or DLT.
Here’s how it works:
- Someone or a computer will transform
- The transaction is transmitted throughout the network.
- A network of computers can confirm the transaction.
- When confirmed, a transaction is added to a block
- The blocks are linked together to create a story.
And it’s the beauty of this one! The process may seem complicated, but it is done in a few minutes with modern technology. And because technology is progressing quickly, I expect things to move even faster than ever.
- A new transaction is added to the system. It is then relayed on a network of computers located worldwide. Computers then solve the equations to ensure the authenticity of the transaction.
- Once a transaction is confirmed, it is placed in a block after confirmation. All blocks are chained to create a permanent history of each transaction.
How are blockchains used?
Even if the blockchain is an integral part of the cryptocurrency, it has other applications. For example, the blockchain can be used to store reliable data on transactions. Many people confuse the blockchain with cryptocurrencies like Bitcoin and Ethereum.
Blockchain is already adopted by certain large companies, such as Walmart, Aig, Siemens, Pfizer and Unilever. For example, IBM Food Trust uses the blockchain to follow Food’s trip before reaching its final destination.
Although some of you can consider this excessive practice, food suppliers and manufacturers adhere to the policy of tracing their products because bacteria such as E. Coli and Salmonella have been found in packaged foods. In addition, there have been isolated cases where dangerous allergens such as peanuts have been accidentally introduced into certain products.
The tracing and identification of the sources of an epidemic is a difficult task that can take months or years. Thanks to the blockchain, however, companies now know exactly where their food takes place – so that they can trace its location and prevent future epidemics.
Blockchain technology allows systems to react much faster in the event of danger. He also has many other uses in the modern world.
What is the decentralization of blockchain?
Blockchain technology is sure, even if it is public. People can access technology using an internet connection.
Have you ever been in a situation where you had all your data stored in one place and this secure place was compromised? Wouldn’t it be great if there was a way to prevent your data from fleeing even when the safety of your storage systems is compromised?
Blockchain technology provides a way to avoid this situation using several computers in different places to store information on transactions. If a computer encounters problems with a transaction, this will not affect other nodes.
Instead, other nodes will use correct information to reference your incorrect node. This is called “decentralization”, which means that all the information is stored in several places.
The blockchain guarantees the authenticity of your data – not just its precision, but also its irreversibility. It can also be used to store data that is difficult to record, such as legal contracts, state identifications or the inventory of a company’s products.
For the advantages and disadvantages of the blockchain
The blockchain has many advantages and disadvantages.
Pros
- The accuracy is increased because there is no human involvement in the verification process.
- One of the big things about decentralization is that it makes information more difficult to falsify.
- Safe, private and easy transactions
- Provides a banking alternative and safe storage of personal information
Disadvantages
- Data storage has limits.
- The regulations are still changing because they differ from one place to another.
- It is likely to be used for illicit activities
Questions frequently asked about the blockchain
I will answer the most frequently asked questions about the blockchain in this section.
Is blockchain a cryptocurrency?
Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It is a large digital book that records each transaction transparently.
Is it possible that the blockchain is hacked?
Yes, the blockchain can be theoretically hacked, but it is a complicated task to accomplish. A network of users constantly examines it, which makes it difficult to hack the blockchain.
What is the most important blockchain company?
Coinbase Global is currently the biggest blockchain company in the world. The company manages a laudable infrastructure, services and technology for the digital currency economy.
Who does the blockchain belong to?
Blockchain is a decentralized technology. It is a chain of distributed registers linked to the nodes. Each node can be any electronic device. Thus, we have a blockage.
What is the difference between Bitcoin and Blockchain technology?
Bitcoin is a cryptocurrency, which is fueled by blockchain technology while the blockchain is a big distributed book of cryptocurrency
What is the difference between blockchain and a database?
Generally, a database is a data collection that can be stored and organized using a database management system. People who have access to the database can display or modify the information stored there. Customer-server network architecture is used to implement databases. While a blockchain is an increasing list of recordings, called blocks, stored in a distributed system. Each block contains cryptographic hash of the previous block, time -to -exploit and transaction information. The modification of the data is not authorized due to the design of the blockchain. Technology allows decentralized control and eliminates the risk of data modification by other parties.
Last saying
The blockchain has a wide range of applications and, over the next 5 to 10 years, we will probably see that it is integrated into all kinds of industries. From finance to health care, blockchain could revolutionize the way we store and share the data. Although there is an hesitation in adopting blockchain systems at the moment, this will not be the case in 2022-2023 (and even less in 2026). Once people get more comfortable with technology and understand how it can work for them, owners, CEOs and entrepreneurs will not be quickly taking advantage of Blockchain technology for their own gain.
