Bytecoin ticker symbol BCN [2] is the first cryptocurrency based on the CryptoNote technology with an open source code designed for anonymous cash settlement. BCN protects the user's privacy with impassive and anonymous transactions. This is a completely independent currency, developing separately from Bitcoin and its forks , the basis for the creation of Bytecoin was the unique CryptoNote technology.
Bytecoin BCN was released to the public on July 4th which can be seen from their first post on their original website [4] which was originally located on the dark web.
As of , Bytecoin has been forked more than 25 times. On March 31, , Bytecoin developers announced their road map for several future releases, among others, the following improvements were mentioned: Bytecoin is an open source software.
Crypto currency uses the principle of Proof-of-work "Proof of work performance". The algorithm for mining in Bytecoin differs in that it actively uses the AES command system for x86 microprocessors and a large amount of memory, which makes mining on the GPU less efficient than for Bitcoin. It uses the unique CryptoNight algorithm, the essence of the algorithm is in the ring signature, which provides the maximum program anonymity for today.
Additional transaction obfuscation was added to this basis. Due to CryptoNote and the obfuscation added to the protocol, passive mixing is provided: Bytecoin advertises itself as a completely anonymous altcoin. Bytecoin offers the following features:. Software developer — A software developer is a person concerned with facets of the software development process, including the research, design, programming, and testing of computer software. Other job titles which are used with similar meanings are programmer, software analyst.
According to developer Eric Sink, the differences between system design, software development, and programming are more apparent, even more so that developers become systems architects, those who design the multi-leveled architecture or component interactions of a large software system.
In a large company, there may be employees whose sole responsibility consists of one of the phases above. In smaller development environments, a few people or even an individual might handle the complete process. The word software was coined as a prank as early as , before this time, computers were programmed either by customers, or the few commercial computer vendors of the time, such as UNIVAC and IBM.
The first company founded to provide products and services was Computer Usage Company in The software industry expanded in the early s, almost immediately after computers were first sold in mass-produced quantities, universities, government, and business customers created a demand for software.
Many of these programs were written in-house by full-time staff programmers, some were distributed freely between users of a particular machine for no charge. Others were done on a basis, and other firms such as Computer Sciences Corporation started to grow.
The industry expanded greatly with the rise of the computer in the mids. In the following years, it created a growing market for games, applications. DOS, Microsofts first operating system product, was the dominant operating system at the time, by the role of cloud developer had been defined, in this context, one definition of a developer in general was published, Developers make software for the world to use.
The job of a developer is to crank out code -- fresh code for new products, code fixes for maintenance, code for business logic, bus factor Software Developer description from the US Department of Labor. Computing platform — Computing platform means in general sense, where any piece of software is executed. It may be the hardware or the system, even a web browser or other application.
The term computing platform can refer to different abstraction levels, including a hardware architecture, an operating system. In total it can be said to be the stage on which programs can run.
For example, an OS may be a platform that abstracts the underlying differences in hardware, platforms may also include, Hardware alone, in the case of small embedded systems. Embedded systems can access hardware directly, without an OS, this is referred to as running on bare metal, a browser in the case of web-based software. The browser itself runs on a platform, but this is not relevant to software running within the browser.
An application, such as a spreadsheet or word processor, which hosts software written in a scripting language. This can be extended to writing fully-fledged applications with the Microsoft Office suite as a platform, software frameworks that provide ready-made functionality. Cloud computing and Platform as a Service, the social networking sites Twitter and facebook are also considered development platforms.
A virtual machine such as the Java virtual machine, applications are compiled into a format similar to machine code, known as bytecode, which is then executed by the VM. A virtualized version of a system, including virtualized hardware, OS, software.
These allow, for instance, a typical Windows program to run on what is physically a Mac, some architectures have multiple layers, with each layer acting as a platform to the one above it. In general, a component only has to be adapted to the layer immediately beneath it, however, the JVM, the layer beneath the application, does have to be built separately for each OS.
Ticker symbol — A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. A stock symbol may consist of letters, numbers or a combination of both, ticker symbol refers to the symbols that were printed on the ticker tape of a ticker tape machine. Stock symbols are unique identifiers assigned to each security traded on a particular market, for example, AAPL is for Apple Inc.
The symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, the allocation of symbols and formatting convention is specific to each stock exchange. In the US, for example, stock tickers are typically between 1 and 4 letters and represent the name where possible. In Europe, most exchanges use three-letter codes, for example Dutch consumer goods company Unilever traded on the Amsterdam Euronext exchange has the symbol UNA, while in Asia, numbers are often used as stock tickers to avoid issues for international investors when using non-Latin scripts.
The symbol of the firm after the merger was XOM, symbols are sometimes reused, in the US the single-letter symbols are particularly sought after as vanity symbols. For example, since Mar Visa Inc. To fully qualify a stock, both the ticker and the exchange or country of listing needs to be known, on many systems both must be specified to uniquely identify the security.
This is often done by appending the location or exchange code to the ticker, although stock tickers identify a security, they are exchange dependent, generally limited to stocks and can change. These limitations have led to the development of other codes in financial markets to identify securities for settlement purposes, the most prevalent of these is the International Securities Identifying Number.
The ISIN identifies the security, not the exchange on which it trades, for instance, Daimler AG stock trades on twenty-two different stock exchanges worldwide, and is priced in five different currencies, it has the same ISIN on each, though not the same ticker symbol. CryptoNote — CryptoNote is an application layer protocol that powers several decentralized privacy oriented digital currencies. Conceptually, it is an evolution of ideas behind bitcoin, both are similar in ways yet different in many others.
CryptoNote currencies use a public ledger that records all balances. Unlike bitcoin, CryptoNotes transactions cannot be followed through the blockchain in a way that reveals who sent or received coins, the approximate amount of a transaction can be known, but the origin, destination, or actual amount cannot be learned.
The only information available is that the amount was lower than the displayed amount. The only people with access to the set of data about a transaction are the sender or receiver of the transaction. CryptoNote uses memory bound function CryptoNight, which cannot be easily pipelined, CryptoNote code was not forked from bitcoins, so it also has other different inner algorithms, like recalculating new difficulty level or new block size.
CryptoNote technology was first described in a whitepaper CryptoNote v 1. CryptoNote is based on many works and protocols and takes into consideration several issues raised formerly.
Like bitcoin, CryptoNote currencies use a public address consisting of numbers and letters that is derived from users public keys. Addresses serve as public IDs of the users, however, unlike bitcoin, CryptoNote transactions hide the connection between the senders and the receivers addresses.
To prevent sender identification, CryptoNote groups the senders public key with several other keys, if ring signatures are used, all possible senders referenced in the transaction are equiprobable and there is no way to determine the exact private key used while signing. This approach does not require dedicated master nodes for mixing coins and it still assures the network that the original sender has the funds in his or her account to send the transaction like an ordinary signature scheme does.
On the receivers end, the technology generates a new key for each money transfer. With senders random data and receiver public address it is possible to create a pair of unique private, sender generates one-time ephemeral key for each transfer and only the receiver can recover the corresponding private key.
No third party can determine if two different transactions were sent to the same recipient, anonymous transactions have a potential problem. Open-source model — Open-source software may be developed in a collaborative public manner. In the early days of computing, programmers and developers shared software in order to learn from each other, eventually the open source notion moved to the way side of commercialization of software in the years Netscapes act prompted Raymond and others to look into how to bring the Free Software Foundations free software ideas, the new term they chose was open source, which was soon adopted by Bruce Perens, publisher Tim OReilly, Linus Torvalds, and others.
The Open Source Initiative was founded in February to encourage use of the new term, a Microsoft executive publicly stated in that open source is an intellectual property destroyer. I cant imagine something that could be worse than this for the software business, IBM, Oracle, Google and State Farm are just a few of the companies with a serious public stake in todays competitive open-source market.
There has been a significant shift in the corporate philosophy concerning the development of FOSS, the free software movement was launched in In , a group of individuals advocated that the free software should be replaced by open-source software as an expression which is less ambiguous.
Software developers may want to publish their software with an open-source license, the Open Source Definition, notably, presents an open-source philosophy, and further defines the terms of usage, modification and redistribution of open-source software. Software licenses grant rights to users which would otherwise be reserved by law to the copyright holder.
Several open-source software licenses have qualified within the boundaries of the Open Source Definition, the open source label came out of a strategy session held on April 7, in Palo Alto in reaction to Netscapes January announcement of a source code release for Navigator. They used the opportunity before the release of Navigators source code to clarify a potential confusion caused by the ambiguity of the free in English.
Many people claimed that the birth of the Internet, since , started the open source movement, the Free Software Foundation, started in , intended the word free to mean freedom to distribute and not freedom from cost. Since a great deal of free software already was free of charge, such software became associated with zero cost. The Open Source Initiative was formed in February by Eric Raymond and they sought to bring a higher profile to the practical benefits of freely available source code, and they wanted to bring major software businesses and other high-tech industries into open source.
Perens attempted to open source as a service mark for the OSI. The Open Source Initiatives definition is recognized by governments internationally as the standard or de facto definition, OSI uses The Open Source Definition to determine whether it considers a software license open source.
Bitcoin — Bitcoin is both a cryptocurrency and an electronic payment system,3 invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto. Bitcoin was introduced on 31 October to a mailing list. The identity of Nakamoto remains unknown, though many have claimed to know it, the system is peer-to-peer, and transactions take place between users directly, without an intermediary.
These transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain, since the system works without a central repository or single administrator, the U. Treasury categorizes bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed, Bitcoin is the largest of its kind in terms of total market value. Bitcoins are created as a reward in a competition in which users offer their computing power to verify and this activity is referred to as mining and successful miners are rewarded with transaction fees and newly created bitcoins.
Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, when sending bitcoins, users can pay an optional transaction fee to the miners. This may expedite the transaction being confirmed, as of February , over , merchants and vendors accept bitcoin as payment. The European Banking Authority and other sources have warned that bitcoin users are not protected by refund rights or chargebacks, the use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and media.
Criminal activities are focused on darknet markets and theft, though officials in countries such as the United States also recognize that bitcoin can provide legitimate financial services.
The word bitcoin occurred in the paper that defined bitcoin published in It is a compound of the bit and coin.
