CRYPTO TOKEN WIKI

He conceptualized a token currency which could be transferred between individuals both safely and privately; again, the similarities to modern day cryptocurrencies are striking. Chaum developed a so-called "blinding formula" to be used to encrypt information passed between individuals. Chaum founded DigiCash to put his concept into practice several years later. Although DigiCash went bankrupt in , the concepts the company put forward as well as some of its formulas and encryption tools played an important role in the development of later digital currencies.

In the s, a number of startups made efforts at furthering the goals of DigiCash. PayPal revolutionized person-to-person payments online. It allowed individuals to quickly and securely transfer money via web browser.

By connecting itself to the eBay community, PayPal secured a dedicated userbase which allowed it to grow and thrive. It remains a major payments service today. PayPal also inspired its imitators, including companies which attempted to provide a means for trading gold via web browser.

One of the more successful of these operations was called e-gold, which offered individuals online credit in exchange for physical gold and other precious metals. This company ran into issues with various types of scams, however, and was eventually shut down by the federal government in In , developer Wei Dai proposed an "anonymous, distributed electronic cash system" called B-money.

Dai suggested two different protocols, including one which required a broadcast channel that was both synchronous and unjammable. Ultimately, B-money was never successful, and indeed, it was quite different from bitcoin in many ways. Nonetheless, it was also an attempt at an anonymous, private, and secure electronic cash system.

In the B-money system, digital pseudonyms would be used in order to transfer currency through a decentralized network. The system even included a means for contract enforcement in-network as well, without the use of a third party. Although Wei Dai proposed a whitepaper for B-money, it was ultimately unable to garner enough attention for a successful launch.

Still, Satoshi referenced elements of B-money in his bitcoin whitepaper roughly a decade later, so the impact of B-money on the current digital currency craze is undeniable. Not to be confused with the contemporary gold-based exchange of a similar name, Bit Gold was another electronic currency system which dates back to the same period as B-money. Proposed by Nick Szabo, Bit Gold came with its own proof-of-work system that in some ways is mirrored by today's bitcoin mining process.

Through this procedure, solutions were compiled cryptographically and then published for the public in much the same way a modern blockchain would function. Perhaps the most revolutionary aspect of the Bit Gold concept, however, had to do with its movement away from centralized status.

Bit Gold aimed to avoid reliance on centralized currency distributors and authorities. Szabo's aim was for Bit Gold to reflect the properties of real gold, thereby enabling users to eliminate the middleman entirely. Bit Gold, like B-money, was ultimately unsuccessful.

However, it too provided inspiration for a large group of digital currencies which would enter the market a decade or more after its introduction. Developed in the mids, Hashcash was one of the most successful pre-bitcoin digital currencies, according to The Merkle. Hashcash used a proof-of-work algorithm to aid the generation and distribution of new coins, much like many contemporary cryptocurrencies.

Indeed, Hashcash also ran into many of the same problems as today's cryptocurrencies today; in , facing an increased processing power need, Hashcash eventually became less and less effective. In spite of the fact that it eventually fizzled out, Hashcash saw a large degree of interest in its heyday. Many of the elements of the Hashcash system worked their way into bitcoin's development as well.

When bitcoin was developed in , it launched a new generation of digital currencies. Bitcoin differs from many of is predecessors in its decentralized status and its development of blockchain technology. However, it's difficult to imagine the creation of bitcoin, let alone the hundreds of other digital currencies which have since launched, without the earlier attempts at cryptocurrencies and electronic cash in the decades before bitcoin was launched.

A blockchain is exactly what it sounds like — a virtual chain of blocks each containing a batch of transactions and other data. Once each block is added to the chain, it becomes immutable, meaning the data stored inside it cannot be changed or removed.

The nodes perform a variety of roles on the network, from storing a full archive of all historical transactions to validating new transaction data. By having a distributed group of people all maintaining their own copy of the ledger, blockchain technology has the following advantages over traditional finance where a master copy is maintained by a single institution:.

Think of it as having a cluster of computers take up the roles of a bank by consistently updating the balance sheets of users. Instead, there are multiple copies of the balance sheets distributed across several computers, with each node, or computer connected to the network, functioning as a separate server. This infrastructural design makes it possible for cryptocurrencies to evade the security mishaps that often plague fiat.

Depending on how big the network is, it can be prohibitively expensive to carry out a coordinated attack. Also, it is worth mentioning that the distributed nature of these digital assets establishes their censorship-resistant attributes. Unlike the case with banks, which governments regulate, cryptocurrencies have their databases spread across the globe. Therefore, when a government shuts down one of these computers or all the computers within its jurisdiction, the network will continue to function because there are potentially thousands of other nodes in other countries beyond the reach of one government.

Now, let us take a look at how crypto transactions are vetted. Recall that blockchains are distributed databases where all the transactions executed on a crypto network are recorded permanently.

Every block of transactions is linked together chronologically in the order the transactions were validated. Because it is impossible to set up a central authority or bank to manage blockchains, crypto transactions are validated by nodes computers connected to a blockchain. So the question is: How do these networks ensure that node operators are willing to partake in the validation process? With incentives, validators are encouraged to participate actively and honestly in the validation process to earn rewards in the form of newly minted created cryptocurrencies.

This incentive system sets the rules that govern the process of picking validators who would, in turn, verify the next batch of transactions. It also ensures that the activities of the validators align with the goal of the network as a whole. Validator nodes found to be involved in actions that undermine the validity of the crypto network can be barred from taking part in subsequent validation processes or punished accordingly. These incentive infrastructures are also known as consensus protocols.

There is a wide range of consensus protocols being used by existing blockchain networks. The two most common ones are:. Tokens are digital assets issued by decentralized applications based on blockchains. These are applications similar to the ones you might find on your smartphone, but instead of being operated by a single company, they run completely autonomously.

Think of it like a free Uber app where taxi drivers and customers can connect together without having to pay the middleman company a cut of profits. Because these applications depend on the infrastructure of blockchains, transactions involving tokens come with an added fee settled in the native cryptocurrency of the blockchain in question. The value of a cryptocurrency usually depends on the utility of its underlying blockchain — though there have been many instances where social media hype and other superficial factors have played a role in pumping up prices.

It all boils down, though, to the demand for the coin relative to its supply and whether the buyer is willing to pay more than the amount the seller initially acquired the coin for. Notably, cryptocurrencies tend to favor a deflationary system, whereby the number of new coins introduced to the market is predictable and gradually reduces over time.

For many cryptocurrencies, another important element is the total number of coins that can ever exist is often fixed. For instance, there will be only 21 million bitcoins created, of which more than 18 million are already in circulation. This deflationary-based system is the complete opposite of what we have in traditional finance, where governments have the license to print an infinite number of fiat notes and inadvertently devalue their currencies.

Bitcoin was the first of the many cryptocurrencies that exist today. Following its introduction in , developers began to create other variants of cryptocurrencies based on the technology powering the Bitcoin network.

In most cases, the cryptocurrencies were designed to improve upon the standards set by Bitcoin. Initially, cryptocurrency was pushed as an alternative to fiat currency based on the premise that it is portable, censorship-resistant, available globally and an affordable means of executing cross-border transactions.

As a result, most crypto holders have shifted their attention to the investment potential of cryptocurrencies, which has since birthed the speculative side of the crypto market. Investors seem to be more concerned about the possibility that the price of a cryptocurrency may rise sometime in the future than whether they can use cryptocurrencies to purchase goods and services, and so crypto is now predominantly viewed as an investment.

What Is Cryptocurrency? Follow Nikopolos on Twitter. Regulation: The global financial system has been based on various fiat currencies for centuries and most countries have a mature set of laws and best practices to regulate their use.

Cryptocurrency, however, is a largely unregulated market, and even when regulations exist they can vary by jurisdiction. Speed and cost: Sending and completing cross-border transactions using cryptocurrency is much faster than using the legacy banking system. Instead of taking several business days, transactions can occur within minutes, often at a fraction of the cost, when compared with using fiat currency.

Supply: Fiat money has an unlimited supply. That means governments and central banks are free to print new currency at will during times of financial crisis.
