What is Blockchain Technology?
Transactional records are stored in Blockchain technology, known as the term “blocks,” of the public in multiple databases, known as “chains.” They are connected in a network through peer-to-peer nodes. “Digital ledger” is what this storage is typically referred to.
Each transaction is authorized by a digital signature from the owner, which safeguards and authenticates the transaction from tampering. So the information that the “digital ledger” contains is very secure.
The digital ledger is like a Google Spreadsheet shared with several computers in a network, where the transactional records are based on purchases that happened. The interesting fact is that everyone can see this data, but no one can’t corrupt it.
Blockchain Technology: Explained
Let’s suppose that you are transferring money to your friends and family from your bank account to theirs. First, you would have to log in to online banking and transfer the amount you wish to the other person using their account number. Then, when the transaction is finished, your bank updates the transaction records. It seems fairly simple, right? But there are potential issues that most people neglect.
These transactions could tamper. A lot of people who know the truth are wary of using these transactions. That’s why there have been more and more third-party payment apps. But this is the main reason why the blockchain was created.
It’s true that Blockchain, technologically, is a digital ledger that is receiving a lot of attention recently. But what are the other reasons why it has become so popular? First, let’s try to understand the whole concept.
Keeping a record of data transactions is very important for the business. But, unfortunately, most of the time, this information is passed through third-party brokers like lawyers increasing time, the cost for the businesses. or brokers, or it is handled in-house. But fortunately for everyone, Blockchain avoids this long process and helps make the transactions very quickly, saving money and time.
Most people assume Bitcoin and Blockchain can be used interchangeably, but that is not the case in reality. Blockchain is a technology that supports different applications related to industries like supply chain, manufacturing, finance, and more. In addition, Bitcoin uses Blockchain technology to be more secure.
With many advantages, Blockchain is an emerging technology in an increasingly digital world:
- Highly Secure: To conduct fraud-free transactions, it uses digital signatures, making it impossible to change the data and corrupt it.
- Decentralized System: You would need the approval of regulatory authorities like banks or the government for transactions, but with Blockchain, transactions are done with mutual trust between users. This results in safer, smoother, and faster transactions.:
How does Blockchain Technology Work?
Recently, you might have noticed that a lot of businesses are integrating blockchain technology. But we need to understand how does this technology work? Is this a simple addition or a significant change? The advancements of Blockchain have the potential to be revolutionary in the future, but they are very young as of now. So, let’s begging to explain this technology:
Three leading technologies are combined for forming Blockchain.
Cryptography keys – consists of two keys. One of them being the Public Key and the other Private Key. These keys make sure that the transactions are successful between all the parties included. Every individual possesses these two keys. They help to secure digital identity references, which is the most important aspect of Blockchain technology. Digital Signature is what is what this identity is referred to.
A peer-to-peer network is merged with the digital signature; many people act as authorities use digital signatures to reach an agreement, among other transactions. When the deal is finalized, it gets verified by a mathematical verification, which results in a successful and safer transaction between two network-connected parties.
The Process of Transaction
The way it confirms and authorizes the transactions is one of blockchain technology’s best features. For instance, if two people wish to perform a transaction with a public key and private key, the first individual party should attach the transaction information to the public key of the second individual. This information is gathered into a block.
This block does contain a timestamp, a digital signature, and other relevant and important information. It should be noted that the block does not include any of the identities of the parts included. Block is later transmitted across all network nodes, and when the right person uses his private key, the transaction gets completed. For the transaction, a digital wallet is needed.
A Bitcoin wallet is a software program in which Bitcoins are stored. Bitcoin wallets facilitate the sending and receiving of Bitcoins and give the user ownership of the Bitcoin balance. Besides that, wallet, Ethereum Wallet is also very popular.
How Blockchain works:
- Hash Encryptions: This technology uses hash encryptions to secure the data, using mainly the SHA256 algorithm to secure the information. The receiver’s address, the transaction, the sender’s address, and their private key details are all transmitted via the SHA256 algorithm. This encrypted information is called hash inception and is transmitted worldwide, and after the verification, it is added to Blockchain. This algorithm makes it impossible to hack the information.
- Mining: The process of adding transactional detail to present digital/public ledger in Blockchain Technology is called “mining.” Even though it is associated most with Bitcoin, it is used to refer to other Blockchain technologies. What mining does is generates the hash of a block transaction, which is very tough to forge, ensuring the safety of the whole Blockchain, and it does all that without needing a central system.
Blockchain Technologies can be set up to operate differently by using different transactions, which is seen only by individuals authorized to, and everyone else is denied. The most well-known example of this technology is Bitcoin. It just shows how huge this technology has become. Blockchain founders are always researching other applications to expand the level of technology and influence of Blockchain. It seems that blockchain will rule the future world of the digital world.
