What Facebooks Cryptocurrency Could Look Like – Barron’s

Photograph by Con Karampelas

Text size

Facebook is reportedly developing a kind of cryptocurrency that will allow people to make transactions within its platform. The plan has leaked out in news reports, though Facebook itself has stayed mum about what exactly its up to.

On Friday, an analyst predicted that the Facebook coin (Facecoin, perhaps?) would actually look more like one of the large public cryptocurrencies such as Bitcoin or Ethereum and less like the internal-payment or loyalty systems that companies like Starbucks (ticker: SBUX) use. And she expects it to benefit major payments players like Visa (V), Mastercard (MA), and PayPal Holdings (PYPL) rather than replace them.

Last week, The Wall Street Journal reported that Facebook (FB) is working on an initiative called Project Libra to create a coin that Facebook users could send to each other. The so-called stablecoin would be pegged to the value of a government-backed currency like the U.S. dollar so it wouldnt fluctuate in price as wildly as Bitcoin.

Asked about the project, a Facebook spokeswoman sent Barrons a statement on Friday saying that the company is exploring ways to leverage the power of blockchain technology. This new small team is exploring many different applications. We dont have anything further to share.

In the absence of more concrete information, analysts are starting to speculate. Moffett Nathansons Lisa Ellis wrote that the Facebook coin could simply end up being an internal payment and behavior-reward system that the social-media giant uses to encourage people to watch ads on its platforms to earn coins. But she thinks its likelier that Facebook creates a more-public coin thats governed by an independent board. (Ethereum, for one, has a foundation thats designed to work something like this.)

The Journal noted that Facebook is working with big payment companies like Visa, indicating it wants to be useful for more than just as a delivery system for loyalty points. In addition, Ellis wrote, an open cryptocurrency system is more likely to encourage commerce over the Facebook system than a closed crypto system, because an open crypto is more liquid (easier to exchange to/from fiat currency, so more likely a consumer is willing to use it). She notes that Facebook already tried a closed payments system called Facebook Credits that failed to take off.

A public system like the one Ellis describes would be good news for payments companies like Visa and Mastercard, which have so far felt little disruption from cryptocurrencies, most of which are too slow to be useful as actual currencies, she argues.

If Facebook launches an open digital wallet and checkout button, the company will need to collaborate with Visa and Mastercard to enable a variety of card-based funding methods in its wallet (similar to Apple Pay, PayPal , or Google Pay), Ellis wrote.

It could also make Facebooks coin a useful asset for people who live in high-inflation countries where the local currency has been devalued, Ellis says. Essentially Facebook would be offering them a coin that is pegged to the value of a more stable currency so it cant be manipulated by the local government.

Thats the same argument people have given for years about Bitcoinwhich would mean Facebook would be a direct competitor to Bitcoin. (The irony of Bitcoin being replaced by a megacorporation is too rich to even address here.)

All this is highly speculative, of course. The idea that Facebook would hand control of its payments platform to an independent foundation seems unlikely at best. That said, its certainly possible that Facebook introduces a more publicly tradable cryptocurrency. The only question at that point is whether the logo would have Mark Zuckerbergs face on it.

How cryptocurrency assets are becoming a new battleground …

Fighting over money is one thing; dealing with bitcoin and other types of cryptocurrency in a divorce is an entirely different story.

As cryptocurrency has surged in popularity, its become much more common for investors to carry shares in the largely unregulated market. For married couples looking to part ways, this means dealing with cryptocurrency as an asset could make for a difficult and lengthy divorce process.

Considering regulations and standards on digital currencies such as bitcoin are still being weighed by governments and financial regulators across the world, could the future of hiding assets during a nasty divorce be lying in its hands?

Cryptocurrency is virtual currency; it lives online and is traded on a blockchain, an encrypted ledger detailing transactions. Since each transaction is associated with a public and private key, its possible for each transaction to be traced back to a single individual.

Cryptocurrency has been around for about a decade, but it became more mainstream around 2017 when bitcoin skyrocketed to a price of $20,000 per coin and caught the public eye, before giving back much of its value in the time since.

In 2018, only 5 percent of the American population held cryptocurrency, according to a survey by the Global Blockchain Business Council. An additional 21 percent of respondents, however, said they were considering adding it to their portfolio.

As cryptocurrency grows in popularity, lawyers all over the world are beginning to face divorce cases with high-value disputes over these digital assets.

Jacqueline Newman, a New York-based matrimonial law attorney, represents all different types of clients, including those divorcing with cryptocurrency. She asks all of her clients to fill out a statement of net worth a comprehensive document detailing income, assets and debt of each party. She says her forms now ask parties to include cryptocurrency, too.

It hasnt gotten to the point where the court forms include it yet, but we have asked on ours and people list it under their general assets, Newman says.

Since bitcoin and other cryptocurrencies are largely unregulated and encrypted, some might think its a perfect place to anonymously stash away funds.

But thats not necessarily the case.

Mark DiMichael, CPA, certified Financial Forensics accountant and fraud examiner, specializes in cryptocurrency. In one recent case, a husband didnt report $100,000-plus in cryptocurrency assets on his statement of net worth. During the discovery process, DiMichael closely analyzed his bank statements and was able to trace the crypto transactions through a crypto-trading platform.

DiMichael warns, however, that cases can get more complicated. The more knowledgeable someone is in crypto, the bigger the threat they pose to successfully hiding the assets.

Although he hasnt worked on a large number of cases involving cryptocurrency so far, DiMichael gives the example of a cybersecurity expert exchanging cash for bitcoin as payment. By conducting the transaction in person, there would be no proof of the transaction occurring making the asset-hiding much more difficult to reveal to the court.

Its really hard to trace if the individual knows what theyre doing, DiMichael says. An expert is going to know not to leave any evidence on their computer, and it can be much more difficult to subpoena.

Edward Davis, a Miami-based asset-recovery attorney and founding shareholder of Sequor Law, says cases of financial infidelity involving crypto are only going to become more frequent in the coming years.

In 15 to 20 years, Davis expects people with large sums of money to turn toward cryptocurrency as a way to hide their assets.

Its a real threat, Davis says. Its not going to come up in the average divorce of Joe versus Mary where they both have regular jobs and are a middle class family. But the wealthy and uber-wealthy who have access to this are going to use it to hide their value.

Matrimonial attorneys interviewed for this story say there arent currently any specific laws regarding cryptocurrency protection during a divorce process. Davis says these laws to protect consumers from fraudulent crypto activity are likely coming, but they will be slow to implement.

The legal infrastructure and regulatory infrastructure for this stuff is way behind, Davis says. If you look at some of the people sitting in Congress some of them are in their 70s and 80s they have no idea what this is. They dont even know what Snapchat is. Youre talking about a generational change [that] is going to [have to] happen before people are confronting this kind of issue.

Another issue for getting a hand on regulating crypto, Davis says, is that theres a wide misunderstanding of how blockchain technology works.

Whenever something new comes along, everyone tends to minimize it, Davis says. Predicting technology is a very hard thing. People who are intimidated or scared or dont understand technology tend to minimize it.

As interest and commonality surrounding crypto continues to increase, experts in the legal field are having to quickly educate themselves on the asset to keep up. Some experts say there isnt enough being done to inform and train legal counsel on the inner workings of the asset.

Most of what DiMichael knows about crypto is self-taught. In 2018, DiMichael published A Forensic Guide to Finding Cryptocurrency in Divorce Litigation. He created the guide after his own research found there werent many resources available on the matter.

Ive seen some courses for it, but I think there should be more training, DiMichael says. Uncovering crypto is fairly complicated, and that can be even harder for someone not trained in crypto.

Most accountants dont understand cryptocurrency, DiMichael adds. More complicated divorce cases involving cryptocurrency can be a lengthy and complicated process and for an accountant learning everything on the fly, this can mean longer hours and a higher bill for the client. DiMichael says that he currently charges $435 per hour.

Davis hasnt worked directly on a case recovering cryptocurrency assets yet, but he has noticed an upswing in industry-related conversations in the past two years. Lawyers, who he says arent technology-savvy by nature, should pay close attention to cryptocurrency and educate themselves on how to manage it in court cases.

The main concern about crypto is how little we understand it and how dangerous it is because its an unregulated, untethered currency, Davis says. This is a real threat and one we have to think about.

How cryptocurrency assets are becoming a new battleground …

What is Cryptocurrency? A 2 Minute Beginner’s Explanation

The term cryptocurrency is a contraction of cryptographic currency. In March 2018, Merriam-Webster announced that they would include this term in their dictionary. Their definition is as follows:

cryptocurrency noun cryptocurrency krip-t-kr-n(t)-s , -k-rn(t)-s : any form of currency that only exists digitally, that usually has no central issuing or regulating authority but instead uses a decentralized system to record transactions and manage the issuance of new units, and that relies on cryptography to prevent counterfeiting and fraudulent transactions. First Known Use: 1990

This definition isnt bad, apart from:

To clarify, the stated decentralized system behind transaction-recording and issuance management is the blockchain.

As the name implies, cryptography is first and foremost in any cryptocurrency. Transactions are only recorded if they meet the network rules, which are defined in the code run by both relaying and mining nodes. Blocks are only included in the blockchain through some form of proof of work, which depends on a cryptographic process.

Similarly, new coins are only issued when miners or stakers(if using a proof-of-stake system) receive their block reward for generating a new, valid block. Therefore, the decentralized system is ultimately ruled by cryptography.

These objections may appear pedantic, but theyre important. As Merriam-Websters definition currently stands, mechanisms like SWIFT or PayPal might be considered cryptocurrencies. While unusually centralized and regulated, such payment mechanisms are also purely digital systems that depend on cryptography to prevent fraud and counterfeiting.

A more correct definition would read as follows:

cryptocurrency noun cryptocurrency krip-t-kr-n(t)-s , -k-rn(t)-s : anyform of currency that usually exists digitally, and that has no central issuing or regulating authority, but instead uses a decentralized, cryptographically secured system to record transactions, manage the issuance of new units, and prevent counterfeiting and fraudulent transactions. First Known Use: 1990

The word usually has been shifted to account for the existence of items like physical cryptocoins and key backups.

More importantly, this definition makes it clear that the security of cryptocurrencies relies entirely on cryptography, but never on centralization or regulation. In other words, the issuance and transaction record of true cryptocurrencies are unaffected by human decision-making.

For convenience, this term is often shortened to crypto. An example is the cryptocurrency-only exchange, Cryptopia.

And cryptocoin has the same meaning as the well-known cryptocurrency news site, CryptoCoinsNews.com.

If its clear from the context that the intended meaning is cryptocurrency, the shortened term coin can be used. This term is derived from the numerous clones of Bitcoin, which often display a unique prefix (such as Litecoin or Dogecoin). But the best example of this usage is the well-known listing site for market capitalization: CoinMarketCap.com.

Cryptocurrencies use blockchains to order transactions. Blockchains are the best (and perhaps only) way to maintain a consensus about the state of a record among a decentralized, trustless network. If a currency relies on a trust in the form of a centrally maintained and managed record, its simply not a cryptocurrency (which is why PayPal and SWIFT arent cryptocurrencies.)

Note: In order to have a trustless, permission-less, decentralized blockchain, you need three main ingredients:

So far, this article has focused on the crypto part of cryptocurrency, but the currency part is equally important. While blockchains are a natural fit for monetary systems, efforts are being made to apply them to other functions (such as timestamping and record-keeping). While such systems can be useful, they cant be considered cryptocurrencies if they serve no monetary function.

In addition to cryptography, computing and networking are essential to the function of cryptocurrencies. These currencies are software, but theyre dependent on computing and networking hardware. Further physical aspects may be involved in certain cryptocurrencies (such as RFID tags or the backing of precious metals).

Under our improved definition, numerous electronic-payment systems in existence fail to qualify as cryptocurrencies. One major example is Ripple (XRP), which is issued by a company that controls all transactions. While Ripple contains cryptographic elements, credit cards do as well.

According to our definition, ICO tokens also arent cryptocurrencies. A single smart contract is responsible for the issuance of ICO tokens, so this system cant be considered to be decentralized, even if its cryptographically secured.

Lightning Networks arent cryptocurrencies either. They lack their own blockchain, and rely on the chain of an underlying coin for initiation and settlement. If Bitcoins Lightning Network succeeds, it will emphasize the critical properties of cryptocurrencies: security, decentralization, and immutability. And itll shift their secondary characteristics (such as speed and scalability) to Lightning Networks and other layered solutions.

Permissioned blockchains are often proposed by corporations or (central) banks, since access to reading and writing about them are restricted to approved parties. Due to the restricted nature of their blockchains, they cant be considered true cryptocurrencies.

The term cryptocurrency was coined (pun intended) to describe Bitcoin, so its best to only apply it to systems that are fundamentally similar to Bitcoin. By stretching the definition to fit every entry on CoinMarketCap (or even the forthcoming state-controlled or bank-controlled coins), the term becomes far too generalized to be meaningful.

Our suggested terms for these not-quite-cryptocurrencies are token or digital asset.

What is Cryptocurrency: Everything You Must Need To Know!

[Updated September 13, 2018]What Is Cryptocurrency: 21st-Century Unicorn Or The Money Of The Future?

This introduction explains the most important thing about cryptocurrencies. After youve read it, youll know more about it than most other humans.

Today cryptocurrencies (Buy Crypto) have become a global phenomenon known to most people. While still somehow geeky and not understood by most people, banks, governments and many companies are aware of its importance.

In 2016, youll have a hard time finding a major bank, a big accounting firm, a prominent software company or a government that did not research cryptocurrencies, publish a paper about it or start a so-called blockchain-project. (Take our blockchain courses to learn more about the blockchain)

But beyond the noise and the press releases the overwhelming majority of people even bankers, consultants, scientists, and developers have a very limited knowledge about cryptocurrencies. They often fail to even understand the basic concepts.

So lets walk through the whole story. What are cryptocurrencies?

Few people know, but cryptocurrencies emerged as a side product of another invention. Satoshi Nakamoto, the unknown inventor of Bitcoin, the first and still most important cryptocurrency, never intended to invent a currency.

In his announcement of Bitcoin in late 2008, Satoshi said he developed A Peer-to-Peer Electronic Cash System.

His goal was to invent something; many people failed to create before digital cash.

Announcing the first release of Bitcoin, a new electronic cash system that uses a peer-to-peer network to prevent double-spending. Its completely decentralized with no server or central authority. Satoshi Nakamoto, 09 January 2009, announcing Bitcoin on SourceForge.

The single most important part of Satoshis invention was that he found a way to build a decentralized digital cash system. In the nineties, there have been many attempts to create digital money, but they all failed.

after more than a decade of failed Trusted Third Party based systems (Digicash, etc), they see it as a lost cause. I hope they can make the distinction, that this is the first time I know of that were trying a non-trust based system. Satoshi Nakamoto in an E-Mail to Dustin Trammell

After seeing all the centralized attempts fail, Satoshi tried to build a digital cash system without a central entity. Like a Peer-to-Peer network for file sharing.

This decision became the birth of cryptocurrency. They are the missing piece Satoshi found to realize digital cash. The reason why is a bit technical and complex, but if you get it, youll know more about cryptocurrencies than most people do. So, lets try to make it as easy as possible:

To realize digital cash you need a payment network with accounts, balances, and transaction. Thats easy to understand. One major problem every payment network has to solve is to prevent the so-called double spending: to prevent that one entity spends the same amount twice. Usually, this is done by a central server who keeps record about the balances.

In a decentralized network , you dont have this server. So you need every single entity of the network to do this job. Every peer in the network needs to have a list with all transactions to check if future transactions are valid or an attempt to double spend.

But how can these entities keep a consensus about these records?

If the peers of the network disagree about only one single, minor balance, everything is broken. They need an absolute consensus. Usually, you take, again, a central authority to declare the correct state of balances. But how can you achieve consensus without a central authority?

Nobody did know until Satoshi emerged out of nowhere. In fact, nobody believed it was even possible.

Satoshi proved it was. His major innovation was to achieve consensus without a central authority. Cryptocurrencies are a part of this solution the part that made the solution thrilling, fascinating and helped it to roll over the world.

If you take away all the noise around cryptocurrencies and reduce it to a simple definition, you find it to be just limited entries in a database no one can change without fulfilling specific conditions. This may seem ordinary, but, believe it or not: this is exactly how you can define a currency.

Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.

How miners create coins and confirm transactions

Lets have a look at the mechanism ruling the databases of cryptocurrencies. A cryptocurrency like Bitcoin consists of a network of peers. Every peer has a record of the complete history of all transactions and thus of the balance of every account.

A transaction is a file that says, Bob gives X Bitcoin to Alice and is signed by Bobs private key. Its basic public key cryptography, nothing special at all. After signed, a transaction is broadcasted in the network, sent from one peer to every other peer. This is basic p2p-technology. Nothing special at all, again.

The transaction is known almost immediately by the whole network. But only after a specific amount of time it gets confirmed.

Confirmation is a critical concept in cryptocurrencies. You could say that cryptocurrencies are all about confirmation.

As long as a transaction is unconfirmed, it is pending and can be forged. When a transaction is confirmed, it is set in stone. It is no longer forgeable, it cant be reversed, it is part of an immutable record of historical transactions: of the so-called blockchain.

Only miners can confirm transactions. This is their job in a cryptocurrency-network. They take transactions, stamp them as legit and spread them in the network. After a transaction is confirmed by a miner, every node has to add it to its database. It has become part of the blockchain.

For this job, the miners get rewarded with a token of the cryptocurrency, for example with Bitcoins. Since the miners activity is the single most important part of cryptocurrency-system we should stay for a moment and take a deeper look on it.

Principally everybody can be a miner. Since a decentralized network has no authority to delegate this task, a cryptocurrency needs some kind of mechanism to prevent one ruling party from abusing it. Imagine someone creates thousands of peers and spreads forged transactions. The system would break immediately.

So, Satoshi set the rule that the miners need to invest some work of their computers to qualify for this task. In fact, they have to find a hash a product of a cryptographic function that connects the new block with its predecessor. This is called the Proof-of-Work. In Bitcoin, it is based on the SHA 256 Hash algorithm.

You dont need to understand details about SHA 256. Its only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.

Bitcoins can only be created ifminers solve a cryptographic puzzle. Since the difficulty of this puzzle increases the amount of computer power the whole miners invest, there is only a specific amount of cryptocurrency token that can be created in a given amount of time. This is part of the consensus no peer in the network can break.

If you really think about it, Bitcoin, as a decentralized network of peers which keep a consensus about accounts and balances, is more a currency than the numbers you see in your bank account. What are these numbers more than entries in a database a database which can be changed by people you dont see and by rules you dont know?

Basically, cryptocurrencies are entries about token in decentralized consensus-databases. They are called CRYPTOcurrencies because the consensus-keeping process is secured by strong cryptography. Cryptocurrencies are built on cryptography. They are not secured by people or by trust, but by math. It is more probable that an asteroid falls on your house than that a bitcoin address is compromised.

Describing the properties of cryptocurrencies we need to separate between transactional and monetary properties. While most cryptocurrencies share a common set of properties, they are not carved in stone.

1) Irreversible: After confirmation, a transaction cant be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.

2) Pseudonymous: Neither transactions nor accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real world identity of users with those addresses.

3) Fast and global: Transaction are propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesnt matter if I send Bitcoin to my neighbour or to someone on the other side of the world.

4) Secure: Cryptocurrency funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers makes it impossible to break this scheme. A Bitcoin address is more secure than Fort Knox.

5) Permissionless: You dont have to ask anybody to use cryptocurrency. Its just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.

1) Controlled supply: Most cryptocurrencies limit the supply of the tokens. In Bitcoin, the supply decreases in time and will reach its final number sometime around the year 2140. All cryptocurrencies control the supply of the token by a schedule written in the code. This means the monetary supply of a cryptocurrency in every given moment in the future can roughly be calculated today. There is no surprise.

2) No debt but bearer: The Fiat-money on your bank account is created by debt, and the numbers, you see on your ledger represent nothing but debts. Its a system of IOU. Cryptocurrencies dont represent debts. They just represent themselves. They are money as hard as coins of gold.

To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens. You cant hinder someone to use Bitcoin, you cant prohibit someone to accept a payment, you cant undo a transaction.

As money with a limited, controlled supply that is not changeable by a government, a bank or any other central institution, cryptocurrencies attack the scope of the monetary policy. They take away the control central banks take on inflation or deflation by manipulating the monetary supply.

While its still fairly new and unstable relative to the gold standard, cryptocurrency is definitely gaining traction and will most certainly have more normalized uses in the next few years. Right now, in particular, its increasing in popularity with the post-election market uncertainty. The key will be in making it easy for large-scale adoption (as with anything involving crypto) including developing safeguards and protections for buyers/investors. I expect that within two years, well be in a place where people can shove their money under the virtual mattress through cryptocurrency, and theyll know that wherever they go, that money will be there. Sarah Granger, Author, and Speaker.

Mostly due to its revolutionary properties cryptocurrencies have become a success their inventor, Satoshi Nakamoto, didnt dare to dream ofit. While every other attempt to create a digital cash system didnt attract a critical mass of users, Bitcoin had something that provoked enthusiasm and fascination. Sometimes it feels more like religion than technology.

Cryptocurrencies are digital gold. Sound money that is secure from political influence. Money that promises to preserve and increase its value over time. Cryptocurrencies are also a fast and comfortable means of payment with a worldwide scope, and they are private and anonymous enough to serve as a means of payment for black markets and any other outlawed economic activity.

But while cryptocurrencies are more used for payment, its use as a means of speculation and a store of value dwarfs the payment aspects. Cryptocurrencies gave birth to an incredibly dynamic, fast-growing market for investors and speculators. Exchanges like Okcoin, poloniex or shapeshift enables the trade of hundreds of cryptocurrencies. Their daily trade volume exceeds that of major European stock exchanges.

At the same time, the praxis of Initial Coin Distribution (ICO), mostly facilitated by Ethereums smart contracts, gave life to incredibly successful crowdfunding projects, in which often an idea is enough to collect millions of dollars. In the case of The DAO it has been more than 150 million dollars.

In this rich ecosystem of coins and token, you experience extreme volatility. Its common that a coin gains 10 percent a day sometimes 100 percent just to lose the same at the next day. If you are lucky, your coins value grows up to 1000 percent in one or two weeks.

While Bitcoin remains by far the most famous cryptocurrency and most other cryptocurrencies have zero non-speculative impact, investors and users should keep an eye on several cryptocurrencies. Here we present the most popular cryptocurrencies of today.

Bitcoin

The one and only, the first and most famous cryptocurrency. Bitcoin serves as a digital gold standard in the whole cryptocurrency-industry, is used as a global means of payment and is the de-facto currency of cyber-crime like darknet markets or ransomware. After seven years in existence, Bitcoins price has increased from zero to more than 650 Dollar, and its transaction volume reached more than 200.000 daily transactions.

There is not much more to say: Bitcoin is here to stay.

Ethereum

The brainchild of young crypto-genius Vitalik Buterin has ascended to the second place in the hierarchy of cryptocurrencies. Other than Bitcoin its blockchain does not only validate a set of accounts and balances but of so-called states. This means that Ethereum can not only process transactions but complex contracts and programs.

This flexibility makes Ethereum the perfect instrument for blockchain -application. But it comes at a cost. After the Hack of the DAO an Ethereum based smart contract the developers decided to do a hard fork without consensus, which resulted in the emerge of Ethereum Classic. Besides this, there are several clones of Ethereum, and Ethereum itself is a host of several Tokens like DigixDAO and Augur. This makes Ethereum more a family of cryptocurrencies than a single currency.

Ripple

Maybe the less popular or most hated project in the cryptocurrency community is Ripple. While Ripple has a native cryptocurrency XRP it is more about a network to process IOUs than the cryptocurrency itself. XRP, the currency, doesnt serve as a medium to store and exchange value, but more as a token to protect the network against spam.

Ripple Labs created every XRP-token, the company running the Ripple network, and is distributed by them on will. For this reason, Ripple is often called pre-mined in the community and dissed as no real cryptocurrency, and XRP is not considered as a good store of value.

Banks, however, seem to like Ripple. At least they adopt the system with an increasing pace.

Litecoin

Litecoin was one of the first cryptocurrencies after Bitcoin and tagged as the silver to the digital gold bitcoin. Faster than bitcoin, with a larger amount of token and a new mining algorithm, Litecoin was a real innovation, perfectly tailored to be the smaller brother of bitcoin. It facilitated the emerge of several other cryptocurrencies which used its codebase but made it, even more, lighter. Examples are Dogecoin or Feathercoin.

While Litecoin failed to find a real use case and lost its second place after bitcoin, it is still actively developed and traded and is hoarded as a backup if Bitcoin fails.

Monero

Monero is the most prominent example of the cryptonite algorithm. This algorithm was invented to add the privacy features Bitcoin is missing. If you use Bitcoin, every transaction is documented in the blockchain and the trail of transactions can be followed. With the introduction of a concept called ring-signatures, the cryptonite algorithm was able to cut through that trail.

The first implementation of cryptonite, Bytecoin, was heavily premined and thus rejected by the community. Monero was the first non-premined clone of bytecoin and raised a lot of awareness. There are several other incarnations of cryptonote with their own little improvements, but none of it did ever achieve the same popularity as Monero.

Moneros popularity peaked in summer 2016 when some darknetmarkets decided to accept it as a currency. This resulted in a steady increase in the price, while the actual usage of Monero seems to remain disappointingly small.

Besides those, there are hundreds of cryptocurrencies of several families. Most of them are nothing more than attempts to reach investors and quickly make money, but a lot of them promise playgrounds to test innovations in cryptocurrency-technology.

The market of cryptocurrencies is fast and wild. Nearly every day new cryptocurrencies emerge, old die, early adopters get wealthy and investors lose money. Every cryptocurrency comes with a promise, mostly a big story to turn the world around. Few survive the first months, and most are pumped and dumped by speculators and live on as zombie coins until the last bagholder loses hope ever to see a return on his investment.

Markets are dirty. But this doesnt change the fact that cryptocurrencies are here to stay and here to change the world. This is already happening. People all over the world buy Bitcoin to protect themselves against the devaluation of their national currency. Mostly in Asia, a vivid market for Bitcoin remittance has emerged, and the Bitcoin using darknets of cybercrime are flourishing. More and more companies discover the power of Smart Contracts or token on Ethereum, the first real-world application of blockchain technologies emerge.

The revolution is already happening. Institutional investors start to buy cryptocurrencies. Banks and governments realize that this invention has the potential to draw their control away. Cryptocurrencies change the world. Step by step. You can either stand beside and observe or you can become part of history in the making.

What is a Cryptocurrency

A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. Many cryptocurrencies are decentralized systems based on blockchain technology, a distributed ledger enforced by a disparate network of computers. A defining feature of a cryptocurrency, and arguably its biggest allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.

The first blockchain-based cryptocurrency wasBitcoin, which still remains the most popular and most valuable. Today, there are thousands of alternate cryptocurrencies with various functions or specifications. Some of these are clones of Bitcoin while others are forks, or new cryptocurrencies that split off from an already existing one.

Cryptocurrencies are systems that allow for the secure payments of online transactions that are denominated in terms of a virtual “token,” representing ledger entriesinternal to the system itself. “Crypto” refers to the fact that various encryption algorithms and cryptographic techniques, such as elliptical curve encryption, public-private key pairs, and hashing functions, are employed.

The first cryptocurrency to capture the public imagination was Bitcoin, which was launched in 2009 by an individual or group known under the pseudonym,Satoshi Nakamoto. As of February 2019, there were over 17.53 million bitcoins in circulation with a total market value of around $63 billion (although the market price of bitcoin can fluctuate quite a bit). Bitcoin’s success has spawned a number of competing cryptocurrencies, known as “altcoins” such as Litecoin, Namecoin and Peercoin, as well as Ethereum, EOS, and Cardano. Today, there are literally thousands of cryptocurrencies in existence, with an aggregate market value of over $120 billion (Bitcoin currently represents more than 50% of the total value).

Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties in a transaction, without the need for a trusted third party such as a bank or credit card company; these transfers are facilitated through the use of public keys and private keys for security purposes. In modern cryptocurrency systems, a user’s “wallet,” or account address, has the public key, and the private key is used to sign transactions. Fund transfers are done with minimal processing fees, allowing users to avoid the steep fees charged by most banks and financial institutions for wire transfers.

Central to the appeal and function of Bitcoin is the blockchaintechnologyit uses to store an online ledger of all the transactions that have ever been conducted using bitcoins, providing a data structure for this ledger that is exposed to a limited threat from hackers and can be copied across all computers running Bitcoin software. Every new block generated must be verified by the ledgers of each user on the market, making it almost impossible to forge transaction histories. Many experts see this blockchain as having important uses in technologiessuch as online voting and crowdfunding, and major financial institutions such as JPMorgan Chase see potential in cryptocurrencies to lower transaction costs by making payment processing more efficient. However, because cryptocurrencies are virtual and do not have a central repository, a digital cryptocurrency balance can be wiped out by a computer crash if a backup copy of the holdings does not exist, or if somebody simply loses their private keys.

At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.

The semi-anonymous nature of cryptocurrency transactions makes them well-suited for a host of nefarious activities, such as money laundering and tax evasion. However, cryptocurrencyadvocates often value the anonymity highly. Some cryptocurrencies are more private than others. Bitcoin, for instance, is a relatively poor choice for conducting illegal business online, and forensic analysis of bitcoin transactions has led authorities to arrest and prosecute criminals. More privacy-oriented coins do exist, such as Dash, ZCash, or Monero, which are far more difficult to trace.

Since prices are based on supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can fluctuate widely. However, plenty of research has been undertaken to identify the fundamental price drivers of cryptocurrencies.Bitcoin has indeed experienced some rapid surges and collapses in value, reaching as high as $19,000 per bitcoin in December of 2017 before returning to around $7,000 in the following months. Cryptocurrencies are thus considered by some economists to be a short-lived fad or speculative bubble. There is concern especially that the currency units, such as bitcoins, are not rooted in any material goods. Some research has identified that the cost of producing a bitcoin, which takes an increasingly large amount of energy, is directly related to its market price.

Cryptocurrencies’ blockchains are secure, but other aspects of a cryptocurrency ecosystem are not immune to the threat of hacking. In Bitcoin’s 10-year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of ‘coins’ stolen. Still, many observers look at cryptocurrencies as hope that a currency can exist that preserves value, facilitates exchange, is more transportable than hard metals, and is outside the influence of central banks and governments.
