If you want to pay online, you need to register an account and provide credit card information. If you do not have a credit card, you can pay via bank transfer. With the advent of cryptocurrencies, these methods may become outdated.
Imagine a world where you can make transactions and many other things without having to provide your personal information. A world where you don’t need to rely on banks or governments anymore. Sounds amazing, doesn’t it? 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 linked to each other like links in a chain.
Blockchain technology was originally invented in 1991 by two mathematicians, Stuart Haber and W. Scott Stornetta. They first proposed the system to ensure that timestamps cannot be tampered with.
A few years later, in 1998, software developer Nick Szabo proposed using a similar type of technology to secure a digital payments system that he called “Bit Gold.” However, this innovation was not adopted until Satoshi Nakamoto claimed to have invented the first blockchain and Bitcoin.
So, what is blockchain technology?
A blockchain is a distributed database shared between nodes of a computer network. It saves information in digital form. Many people first heard about blockchain technology when they started searching for information about Bitcoin.
Blockchain is used in cryptocurrency systems to ensure secure and decentralized records of transactions.
Blockchain technology has allowed people to ensure the accuracy and security of a data record without needing a third party to ensure accuracy.
To understand how blockchain works, consider these basic steps:
- Blockchain collects information into “blocks.”
- A block has storage capacity, and once used, it can be closed and linked to a previously submitted block.
- Blocks form chains called “Blockchains”.
- More information will be added to the block with the most content until its capacity is full. The process repeats itself.
- Each block in the chain has a specific timestamp and cannot be changed.
Let’s learn more about blockchain technology.
How does blockchain technology work?
Blockchain technology records digital information and distributes it across the network without changing it. The information is distributed among many users and is stored in a permanent, immutable ledger that cannot be changed or destroyed. This is why blockchain is also called “Distributed Ledger Technology” or DLT.
Here’s how it works:
- Someone or a computer will handle it
- The transaction is transmitted over the network.
- A network of computers can confirm the transaction.
- When it is confirmed, the transaction is added to the block
- Blocks are linked together to create a record.
That’s the beauty of it! The process may seem complicated, but it is completed in a few minutes using modern technology. Because technology is advancing so quickly, I expect things to move faster than ever before.
- A new transaction is added to the system. It is then relayed to a network of computers located around the world. Computers then solve the equations to ensure the transaction is valid.
- Once a transaction is confirmed, it is placed in a block after confirmation. All blocks are linked together to create a permanent record of each transaction.
How is blockchain used?
Although blockchain is an integral part of cryptocurrency, it has other applications. For example, blockchain technology can be used to store reliable data about transactions. Many people confuse blockchain with cryptocurrencies such as Bitcoin and Ethereum.
Blockchain technology is already being adopted by some big-name companies, such as Walmart, AIG, Siemens, Pfizer, and Unilever. For example, IBM’s Food Trust uses blockchain technology to track food’s journey before it reaches its final destination.
Although some of you may consider this practice excessive, food suppliers and manufacturers adhere to a traceability policy for their products because bacteria such as E. coli and Salmonella have been found in packaged foods. In addition, there have been isolated cases in which dangerous allergens such as peanuts have been accidentally introduced into some products.
Tracking and identifying the sources of an outbreak is a difficult task that can take months or years. However, thanks to blockchain technology, companies now know exactly where their food is located, so they can track its location and prevent future outbreaks.
Blockchain technology allows systems to react much faster in the event of a risk. It also has many other uses in the modern world.
What is Blockchain decentralization?
Blockchain technology is secure, even if it is public. People can access technology using an internet connection.
Have you ever faced a situation where you stored all your data in one place and that secure place got hacked? Wouldn’t it be great if there was a way to prevent your data from being leaked even when the security of your storage systems is compromised?
Blockchain technology provides a way to avoid this situation by using multiple computers in different locations to store information about transactions. If one computer has problems with a transaction, it will not affect the other nodes.
Instead, other nodes will use the correct information to cross-reference the incorrect node. This is called “decentralization,” which means all information is stored in multiple places.
Blockchain technology ensures the authenticity of your data, not only its accuracy, but also its irreversibility. It can also be used to store data that is difficult to record, such as legal contracts, state identities, or a company’s product inventory.
Pros and cons of Blockchain
Blockchain has many advantages and disadvantages.
Pros
- Accuracy is increased because there is no human intervention in the verification process.
- One of the great things about decentralization is that it makes it difficult to manipulate information.
- Secure, private and easy transactions
- Provides a banking alternative and secure storage of personal information
cons
- Data storage has limitations.
- Regulations are always changing, because they differ from one place to another.
- It carries the risk of being used for illegal activities
Frequently asked questions about Blockchain
I will answer the most frequently asked questions about blockchain in this section.
Is Blockchain a cryptocurrency?
Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It is a digital ledger that seamlessly records every transaction.
Is it possible to hack Blockchain?
Yes, blockchain technology can be hacked in theory, but it is a complex task to achieve. It is constantly reviewed by a network of users, which makes hacking the blockchain difficult.
What is the most prominent blockchain company?
Coinbase Global is currently the largest blockchain company in the world. The company operates commendable infrastructure, services and technology for the cryptocurrency economy.
Who owns the blockchain?
Blockchain is a decentralized technology. It is a chain of distributed ledgers linked to nodes. Each node can be any electronic device. Thus, one owns the blockchain.
What is the difference between Bitcoin technology and Blockchain technology?
Bitcoin is a cryptocurrency, powered by Blockchain technology while Blockchain is a distributed ledger of cryptocurrency
What is the difference between Blockchain and Database?
In general, a database is a collection of data that can be stored and organized using a database management system. People with access to the database can view or edit the information stored there. A client-server network architecture is used to implement databases. Whereas a blockchain is a growing list of records, called blocks, stored in a distributed system. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction information. Data modification is not allowed due to the design of the blockchain. This technology allows decentralized control and eliminates the risk of data modification by other parties.
Final say
Blockchain technology has a wide range of applications, and over the next five to ten years, we will likely see it integrated into all types of industries. From finance to healthcare, blockchain technology could revolutionize the way data is stored and shared. Although there is some hesitation in adopting blockchain systems at the moment, this will not be the case in 2022-2023 (and even less so in 2026). Once people become more comfortable with the technology and understand how it can work to their advantage, owners, CEOs, and entrepreneurs alike will be quick to leverage blockchain technology for their own gain.
