Bitcoin

Bitcoin is a digital asset and a payment system invented by Satoshi Nakamoto, who published the invention in 2008 and released it as open-source software in 2009. The system is peer-to-peer; users can transact directly without an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the block chain. The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value.

Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins. Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.

Radhika (Maia Katrak) has been married for over ten years to Nikhil (Boman Irani) and is having an affair for the past six months with an interior designer, Krish. Radhika is now pregnant with Krish’s child and pours out her plight to a friend, Rita (Anahita Oberoi). She mentions a particular incident where she suffered a miscarriage of their second child that had started the rift. Radhika says that she did not want to have this baby, while Nikhil did, and adds that both of them have not quite gotten over the miscarriage. Radhika wants to come clean with Nikhil, while Rita advises her to sort things out in her mind first as to what she wants before she tells Nikhil. Radhika then plays out various scenes in her mind where she has told Nikhil of her affair and visualizes different ways in which Nikhil could react.

Internet

The Internet is the global system of interconnected mainframe, personal, and wireless computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, Usenet newsgroups, telephony, and peer-to-peer networks for file sharing.

Although the Internet protocol suite has been used by academia and the military industrial complex since the early 1980s, rapid adoption of its use was driven by events of the late 1980s and 1990s such as more powerful and affordable computers, the advent of fiber optics, the popularization of HTTP and the Web browser, and a push towards opening the technology to commerce. Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the 20 years since 1995, Internet use has grown 100-times to reach over one third of the world population, leading to its services and technologies being incorporated into virtually every aspect of contemporary life. The impact of the Internet has been so immense that it has been referred to as the "8th continent".
