How does blockchain technology work

Cryptocurrencies and Bitcoin back the blockchain technology. A blockchain is the arrangement of data which represent the financial ledger entry or records the transaction. Every transaction is digitally signed to make sure of its authenticity and where nobody can tamper it. So the ledger and the current transactions in it are presumed to be of high probity. The blockchain is thus a public ledger which is decentralized and distributed. It is simpler to understand.

Does the blockchain technology sound as new technology?

The blockchain is an undoubtedly an intelligent invention for the people called by their pseudonym, Satoshi-Nakamoto. But since its evolution everyone’s question is to know about the blockchain. By permitting digital data to be assigned and not be copied, blockchain technology designed the backbone for the new kind of internet.

Initially, this is created for the bitcoin, digital currency. The technology is now making a way for other potential methods. Bitcoin also termed digital gold, and the total value of the currency is approximately $112 billion US. So, having a through an understanding of this novel technology explains why this is considered a revolutionary.

Blockchain Technology

The blockchain technology is a reliable digital ledger of financial and economic transactions which can be processed to record transactions virtually. As it is online, the data which is kept on the blockchain is continually reconciled and shared. This is one of the ways of utilizing the network with its distinct benefits. The blockchain database is stored generally in a public location and easily verifiable. As this technology is decentralized no centralized version of data is available for a hacker to corrupt. Hosted on multilevel computers the data is accessed by everyone on the internet.

Working Model

When a new element or transactions comes into a blockchain, usually a majority of the elements within a blockchain are implemented. After the transaction is assured they must execute the algorithms to verify and evaluate historical data. The algorithm must be compared to the public records of information such as the SEC (Securities-Exchange-Commission). With blockchain, the work is left to the networks of the online computers. Generally, these networks consist of 1000s of computers that are scattered across the world.

Moreover, after the data is verified the nodes agree and the signature is valid, the new block of the transaction is accepted. The accepted transactions are stored in the ledger and a block which is new is affixed to the chain of transactions. If many nodes are not conceded then that particular transaction is denied and not added in the chain. The shared consensus makes the blockchain to work as a distributed ledger. There is no need of unifying authority or some central authority where the transactions are valid.
Having said that, the block has to be given a hash. Then the most recent block is added to the blockchain. Once it is hashed, the block is appended to the blockchain.

How blockchains are structured?

Blockchains are made to work in many ways which use different mechanisms. These devices, in turn, defines the members in the chain and eliminates everyone else. For example, Bitcoin uses an unknown public ledger in which any person can participate. To use blockchain privately, many small companies employ verified blockchains to control the participants in transaction activity.


The blockchain is one of the newest term and the biggest buzzword in technology right now. The blockchain provides its internet users with the capability of creating the value. Besides, it verifies the digital information. Consequently, this is a place used for building the framework for a distributed ledger that is based on e-commerce.
