The Blockchain is a distributed ledger of transactions. Each transaction is called a block and the entire chain, from the very first transaction to the most recently completed transaction, is replicated to all nodes in a network.
There are three types of blockchain networks: public, private, and consortium. The public blockchain has unrestricted access to all network participants, like Bitcoin. A private blockchain is used within a single company, consortium blockchains are best suited for small business networks where the participants are known to each other.

Blockchain technology enables peer-to-peer transactions without requiring an intermediary or central authority for validation or processing all of the transactions. The network of nodes shares and sync with each other to maintain a common ledger. The process of validation is done automatically through the consensus mechanism, where every node on the network comes to an agreement about which transactions are valid based on pre-agreed rules. This ensures that both participants & nonparticipants can identify fraudulent behaviour.
The blockchain runs on a distributed network of nodes, each node stores the complete blockchain and maintains a synchronizing copy. In order to prevent the potential for malicious behaviour between participants, transactions are grouped together in a block which is then validated by all peers on the network. The new transaction is assigned a unique code called a hash – just like a fingerprint – which is then added to the existing blockchain.
The invention of Blockchain technology was largely attributed to Satoshi Nakamoto, who proposed bitcoin in 2008 as an electronic payment system based on mathematical proof. The first-ever cryptocurrency (bitcoin) was launched in 2009 and gained instant popularity among the masses. The underlying technology behind bitcoin is called Blockchain which has far-reaching implications beyond financial services.
Blockchain technology enables the creation of new business models and opportunities by building trust, transparency, and security. Blockchain is a disruptive technology that will bring about an Internet revolution. It will change the way we as humans interact with everything – from financial transactions to storing personal data & digital identities.
How Does Bitcoin Work?
Bitcoin is a digital or virtual currency that uses peer-to-peer technology to facilitate instant payments. Bitcoin is created as a reward for a process known as mining. Bitcoin can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.
Bitcoin is a digital currency that’s not tied to a bank or government and allows users to spend money anonymously. The coins are created by users who “mine” them by lending computing power to verify other users’ transactions. They receive bitcoins in exchange. The coins also can be bought and sold on exchanges with the U.S. dollars and other currencies.
Bitcoin can also be used to make purchases with a variety of online retailers. Exchange rates are listed on the Mt. Gox website, but prices fluctuated by about 2 percent Tuesday afternoon from the previous day’s level. Bitcoin gets some negative publicity because it has been featured in use by criminal organizations to launder money.
What are the Advantages of Bitcoin?
Some advantages of Bitcoin include:
- – Bitcoin is global and can be used by anyone, anywhere.
- – Transactions are fast, secure, and easy to use.
- – Bitcoin is a deflationary currency, meaning that its value increases over time.
- – It’s an open-source project with a large community of developers.

Electricity Usage of Bitcoin Mining
To generate each bitcoin, a complex algorithm is run that requires miners to complete 50.7 quintillion calculations per second. The power needed for one hour of bitcoin mining is more than the yearly consumption of almost 4 million US homes. According to Arvind Narayanan, an assistant computer science professor at Princeton, the cost of electricity is enough to drive bitcoin’s price down to zero. According to one estimate, the total electricity consumption for mining bitcoins is more than 159 countries.
The Future of Bitcoin
Bitcoin looks like it will continue to grow as a cryptocurrency and a digital payment system. It may also continue to be a volatile asset.
