Readers may remember CCN’s coverage of PaidBooks.com, a site run by the friendly folks behind Bitcoin Aliens. It has the same functionality as a regular faucet, but instead pays users for reading classic books. It is one of the more interesting and engaging methods of giving away free money, as it gives the user the opportunity to engage in more ways than simply getting around a CAPTCHA and pressing a couple of buttons. Since we first wrote about PaidBooks, they seem to have converted to Bitcoin Cash via a service called AirDrips. BCH is easily converted to Bitcoin, if desired, via services like ShapeShift. You create an accout at AirDrips and then you are able to read books and get paid. They also offer other similar things such as watching videos for money.
A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold[91] or store bitcoins,[92] due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A better way to describe a wallet is something that "stores the digital credentials for your bitcoin holdings"[92] and allows one to access (and spend) them. Bitcoin uses public-key cryptography, in which two cryptographic keys, one public and one private, are generated.[93] At its most basic, a wallet is a collection of these keys.
In the Bitcoin network, the blockchain is not only shared and maintained by a public network of users — it is also agreed upon. When users join the network, their connected computer receives a copy of the blockchain that is updated whenever a new block of transactions is added. But what if, through human error or the efforts of a hacker, one user’s copy of the blockchain manipulated to be different from every other copy of the blockchain?
Nobody owns the Bitcoin network much like no one owns the technology behind email or the Internet. Bitcoin transactions are verified by Bitcoin miners which has an entire industry and Bitcoin cloud mining options. While developers are improving the software they cannot force a change in the Bitcoin protocol because all users are free to choose what software and version they use.

One of the Bitcoin blockchain's most innovative aspects is how it incentivizes nodes to participate in the intensive consensus-building process by randomly rewarding one node with a fixed bounty (currently 12.5 BTC) every time a new block is settled and committed to the chain. This accumulation of Bitcoin in exchange for participation is called "mining" and is how new currency is added to the total system afloat.
Professional services network Deloitte recently surveyed 1,000 companies across seven countries about integrating blockchain into their business operations. Their survey found that 34% already had a blockchain system in production today, while another 41% expected to deploy a blockchain application within the next 12 months. In addition, nearly 40% of the surveyed companies reported they would invest $5 million or more in blockchain in the coming year. Here are some of the most popular applications of blockchain being explored today.

On 1 August 2017, a hard fork of bitcoin was created, known as Bitcoin Cash.[107] Bitcoin Cash has a larger block size limit and had an identical blockchain at the time of fork. On 24 October 2017 another hard fork, Bitcoin Gold, was created. Bitcoin Gold changes the proof-of-work algorithm used in mining, as the developers felt that mining had become too specialized.[108]


Researchers and technologists alike are talking about how blockchain technology is the next big thing across industries from finance to retail to even healthcare. According to Gartner, their client inquiries on blockchain and related topics have quadrupled since August 2015. This article attempts to provide a short executive summary on what blockchain technology is, how it works, and why has it captured everyone’s fancy.
Bitcoin is the most secure and robust cryptocurrency in the world, currently finding its way across the world of business and finance. Bitcoin was thought of as Internet money in its early beginnings. Unlike fiat currencies Bitcoin is a decentralized currency. That means that a network of users control and verify transactions instead of a central authority like a bank or a government.
Whenever referring to the price of Bitcoin as it relates to fiat currency, the price being discussed is almost certainly an aggregate average of the price across various exchanges’ order books. Because bids and asks are instructions executed at a certain price, a large market buy would fill through several orders at incremental price levels and subsequently move the price of bitcoin up or down.
Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto[9] and released as open-source software in 2009.[10] Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[11] products, and services. Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[12]
