Digital fingerprinting is the identification of large data files or structures using truncated information. A fingerprinting algorithm is one that reduces a larger data set to a very small data set, sometimes called a bit string, to promote efficient identification and search protocols. One type of common fingerprint algorithm is called a hash function. These functions change a larger data set, sometimes known as a key, into a shorter data set, which may be called a hash. These altered pieces of data help make search techniques more agile. One type of digital fingerprinting application is related to new digital media files. Experts note that digital fingerprinting helps a user locate a specific file to verify whether a file has been altered, while actually facilitating copyright protection. This involves using a fingerprint identifier to conduct protected file searches for other online file instances. Digital fingerprinting plays other roles for average end users, such as ...

A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price contraction. The trendline is among the most important tools used by technical analysts. Instead of looking at past business performance or other fundamentals, technical analysts look for trends in price action. A trendline helps technical analysts determine the current direction in market prices. Technical analysts believe the trend is your friend, and identifying this trend is the first step in the process of making a good trade. To create a trendline, an analyst must have at least two points on a price chart. Some analysts like to use different time frames such as one minute or five minutes. Others look at daily charts or weekly charts. Some analysts put aside time altogether...

A “fork,” in programming terms, is an open-source code modification. Usually the forked code is similar to the original, but with important modifications, and the two “prongs” comfortably co-exist. Sometimes a fork is used to test a process, but with cryptocurrencies , it is more often used to implement a fundamental change, or to create a new asset with similar (but not equal) characteristics as the original. Not all forks are intentional. With a widely distributed open-source codebase, a fork can happen accidentally when not all nodes are replicating the same information. Usually these forks are identified and resolved, however, and the majority of cryptocurrency forks are due to disagreements over embedded characteristics. There are two main types of programming fork: hard and soft. Hard forks A hard fork is a change to a protocol that renders older versions invalid. If older versions continue running, they will end up with a different protocol and with differ...

A digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document. As the digital equivalent of a handwritten signature or stamped seal, a digital signature offers far more inherent security, and it is intended to solve the problem of tampering and impersonation in digital communications. Digital signatures can provide the added assurances of evidence of origin, identity and status of an electronic document, transaction or message and can acknowledge informed consent by the signer. In many countries, including the United States, digital signatures are considered legally binding in the same way as traditional document signatures. How digital signatures work Digital signatures are based on public key cryptography , also known as asymmetric cryptography. Using a public key algorithm, such as RSA, one can generate two keys that are mathematically linked: one private and one publ...

Tested for decades, Mimblewimble uses elliptic-curve cryptography that requires smaller keys than other cryptography types. In a network that is using the Mimblewimble protocol, there are no addresses on the blockchain, and the network’s data storage is highly efficient. Mimblewimble needs about 10% of the data storage requirements of the Bitcoin network. This makes Mimblewimble highly scalable for storing the blockchain , significantly faster, and less centralized. Furthermore, the nature of the protocol allows for private transactions that are highly anonymous (more about this later). The birth of Mimblewimble Rejoice, Harry Potter fans! Another reference is coming from the movie fan world. The Mimblewimble Whitepaper   was first published on July 2016 in the Bitcoin research channel under the anonymous author name of Tom Elvis Judisor – the French name for Voldemort. Soon after the whitepaper was published – at the end of 2016 -, another anonymous user wit...

Famous for its magnificent Art Nouveau architecture, the city of Ålesund is one of Norway's most popular tourist destinations. Not only is it blessed with one of those picture-perfect Norwegian settings, surrounded by fjords and the high peaks of the Sunnmøre Alps, it has also benefited from the addition of many new cultural and entertainment attractions, byproducts of the incredible increase in wealth the nation has experienced in recent years. Explore Art Nouveau Ålesund The picture-perfect Art Nouveau heart of Ålesund, with its stunning architecture, towers, turrets, and other imaginative ornamentation, really needs to be explored on foot. For a fascinating insight into the city's architecture, the top things to do here include tagging along with an organized walking tour or picking up an informative guide from a tourist office or bookstore. Ålesund Harbor Ålesund's harbor lies between the islands of Nørvøy and Aspøy, and is shelter...

An options contract is an agreement between two parties to facilitate a potential transaction on the underlying security at a preset price, referred to as the strike price, prior to the expiration date. The two types of contracts are put and call options, both of which can be purchased to speculate on the direction of stocks or stock indices, or sold to generate income. For stock options, a single contract covers 100 shares of the underlying stock. The Basics of an Options Contract In general, call options can be purchased as a leveraged bet on the appreciation of a stock or index, while put options are purchased to profit from price declines. The buyer of a call option has the right but not the obligation to buy the number of shares covered in the contract at the strike price. Put buyers have the right but not the obligation to sell shares at the strike price in the contract. Option sellers, on the other hand, are obligated to transact their side of the...
