If you have been following banking, investing, or cryptocurrency over the last ten years, you may have heard the term “blockchain technology,” the record-keeping technology behind the Bitcoin network.
Blockchain technology is a decentralized, distributed ledger that records the provenance of a digital asset. By it’s inherent design, the data on a blockchain is unable to be modified, which makes it a legitimate disruptor for industries like payments, cybersecurity and healthcare.
Blockchain is the technology that maintains all the record behind the trading of bitcoins. As a database, it is different from normal databases as it stores information in a chained sequence. The idea of a blockchain originated in the early 90s as a system where documents and information could be stored without any risk of being tampering. However, the launch of bitcoin in 2009 gave a renewed importance to blockchain technology in the world.
If you are new to Blockchain, then this is the right platform to gain solid foundational knowledge. In this article, you will learn what Blockchain technology is, how Blockchain works, why it’s important in future.
Transactional records are stored in Blockchain technology is known as the term “blocks”. A block in the blockchain techology is a series of transactions. Such blocks together form the blockchain, which is a system that records the information of all transactions. They are connected in a network through peer-to-peer nodes. The blockchain system is highly secured and considered to be impossible to alter or hack. Each transaction in blockchain is authorized by a digital signature from the owner, which safeguards and authenticates the transaction from tampering. As more and more people participate in blockchain transactions. These transactions are added to be as blocks’ series. A ledger is maintained for each of these participants. Which is maintained in a decentralised database, known as the Distributed Ledger Technology (DLT). Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash. Blockchain is an especially promising and revolutionary technology because it helps reduce risk, stamps out fraud and brings transparency.
In Recent years, you may have noticed that Blockchain technology is being integrated by a lot of businesses. But we need to understand, how does the block technology work? If the advancements of Blockchain have the potential to be revolutionary in the future;
The new data is recorded in a fresh block. Once a block is filled with data, it is added to the chain as a part of the usual blockchain technology procedure.
To go into further detail, each new transaction is transmitted within a network of peer-to-peer computers.
This network performs a check and confirm the validity of the new transaction. Once the validity is confirmed, the transaction enters into a fresh block. Subsequently forming part of a history of similar historical transactions.
Apart from bitcoin information, blockchain technology is also used to store any important business information like contracts and commercial data.
An important feature of blockchain technology is its transparency. Anyone enter into the network can view the events happening in the blockchain. With their nodes, people can check the latest status and all the updates happening in the world of bitcoin.
1. Cryptographic keys
2. A peer-to-peer network containing a shared ledger
3. A means of computing, to store the transactions and records of the network
Cryptography keys consist of two keys – Public key and Private key. These keys help in performing successful transactions between two parties. Each individual has these two keys. They use these key to produce a secure digital identity reference. This secured identity is one of the most important aspect of Blockchain technology. In the world of cryptocurrency, this secured identity is referred to as ‘digital signature’ and is used for authorizing and controlling transactions of the two parties.
The security of the blockchain is ensured through the hash codes. The hash codes convert digital transactions into a series of numbers and letters. Each block gets time-stamped, and it is nearly impossible to alter the content of the blocks in the chain and also known as Cryptographic keys.
The reason it is nearly impossible to hack blockchain is that any change in the hacker’s copy of blockchain will stand out among all peer-to-peer copies. The hacked copy will immediately be eliminated and automately reproduce the blocks.
The digital signature is merged with the peer-to-peer network; a huge number of individuals who act as authorities use the digital signature in order to reach the trnsaction securely, inorder to avoid other issues. When they authorize a deal, it is certified by using mathematical verification. Which provides you a successful secured transaction between the two network-connected parties.
Blockchain Technologies is operate in different ways, by using different mechanisms for the transactions and storage. Which is seen only by individuals who are authorized. The most well-known example of this blockchain technology is Bitcoin. It just shows how huge this technology has become buzz over the world. Blockchain founders are always researching other applications in order to expand the level of technology and how to influence of Blockchain. It seems that blockchain will rule the future world of the digital world.
