The top 10 cryptos explained


With over 1500 cryptos in circulation and new tokens being introduced all the time, it’s almost impossible to stay up to date with the market.

Luckily, only a handful of these truly influence the industry, so understanding what these cryptos do and how they work is key to understanding the whole space.

In this artcle we’ll take a quick look at 10 of the most important and interesting cryptos, and simply explain what they do and where they’re going.

Bitcoin (BTC)

Short explanation

Internet money and digital gold.

Longer explanation

Bitcoin is the original cryptocurrency. Released in early 2009, it is a new form of internet money that is fundamentally different from existing currencies.

It is decentralised, meaning it isn’t controlled by any single company or person, and all transactions are peer-to-peer. The history of all transactions is continually being verified by powerful computers, so it is impossible to change once a transaction has been accepted.

This means that anybody in the world is able to buy bitcoin and send money to anybody else cheaply and quickly, which has never been possible before.

Platform

Bitcoin blockchain, using Proof-of-Work (PoW) consensus.

Current issues

Scalability. Bitcoin can typically handle 5–7 transactions per second, with fees from a few cents to a few dollars. When the transaction volume on the network increases, fees skyrocket and transactions take a long time to clear.

In contrast, Visa and Mastercard can reportedly handle around 2000 transactions per second.

In order to be a global payments system, Bitcoin needs to improve on this dramatically.

Ethereum (ETH)

Short explanation

Developer platform, as well as programmable contracts and money.

Longer explanation

Ethereum utilises smart contracts, which allow somebody to send money to another person automatically, but only when a certain set of conditions are met. For example, during the process of selling a house, the buyer and seller could enter into a smart contract that transfers ownership to the buyer, and money to the seller automatically once a deal has been reached.

The other major benefit Ethereum holds is its developer platform, that allows decentralised applications (or Dapps) to be built on top of Ethereum. An easy way to think about this is that Apple or Microsoft allow developers to build applications on top of their software, and Ethereum takes a similar approach. It has its own functions, but also allows other developers to use its blockchain to build new applications and uses.

This has also given rise to ICOs (initial coin offerings) being held on Ethereum’s network. ICOs allow developers working on new blockchain technologies to raise money by selling off tokens in their future application.

Platform

Ethereum blockchain, currently using PoW, but will eventually move to Proof-of-Stake (PoS).

Current issues

Ethereum has a few issues at the moment. It is suffering the same scaling problems as Bitcoin due to the inherent size of their transaction capacity (more on how blockchain tech works here).

It’s become clear since the crash of crypto prices in early 2018 that the market for Dapps is much smaller than first thought, so Ethereum is experiencing slower than expected growth.

There are also other platforms such as EOS creating similar technology that’s simpler to use, which are putting pressure on Ethereum in the long term.

Ripple (XRP)

Short explanation

Enterprise payment network.

Longer explanation

Currently it takes days and massive fees for international payments to go through. Ripple (or the token XRP) is intended to be used by banks and payment providers for rapid, cross-border payments with incredibly low fees.

Platform

Distributed ledger (but not a blockchain) owned and operated by Ripple Labs, using a ‘proof-of-correctness’ consensus algorithm.

Current issues

Ripple is the name of the company that created and owns most of the XRP token. It is not considered a decentralised cryptocurrency, as Ripple owns over 50% of all XRP tokens in circulation, as well as the majority of validator nodes in the XRP network.

This is not to say that Ripple the company won’t be successful with their technology, but it should not be considered in the same category as true cryptos such as Bitcoin and Ethereum, and has a long way to go to prove that it’s a reliable, trustworthy platform for international payments.

Bitcoin Cash (BCH)

Short explanation

Bitcoin clone, internet money.

Longer explanation

Bitcoin Cash was born from a rift in the Bitcoin community over how to scale the network. Those who believed that the Bitcoin block size should be increased split off to create Bitcoin Cash. Each block is 8MB instead of Bitcoin’s 1MB, so BCH can handle up to 60 transactions per second compared to BTC’s 7.

Here’s a deeper explanation of the fork and why it occurred.

Platform

Bitcoin Cash blockchain, hard forked from Bitcoin in August 2017, using PoW consensus.

Current issues

Bitcoin Cash and its creators have been in an endless quest to prove the legitimacy of BCH over BTC, which has resulted in them being involved in some potentially shady activity.

The network appears to be far more centralised than Bitcoin, and infighting between the lead developers and marketers plagues the brand. BCH sees itself as the ‘true bitcoin’, but lags far behind the original in average users and transaction volume.

EOS (EOS)

Short explanation

Decentralised applications and smart contracts.

Longer explanation

EOS is building a platform for building decentralised applications and smart contracts. It is often compared to Ethereum that does much the same thing already, but EOS appears to be much easier for developers to build on, as well as having a broader range of features.

Platform

EOS blockchain using delegated proof-of-stake (dPoS).

Current issues

The EOS mainnet was launched on the 1st of June, 2018 after a 12 month crowd sale. It is therefore the youngest crypto on this list, and has a long way to go in proving that it is a viable crypto in its own right, let along a possible alternative to Ethereum.

Litecoin (LTC)

Short explanation

Faster Bitcoin.

Longer explanation

Litecoin is often thought of as the silver to Bitcoin’s gold. It has a similar function, but is focused more on small, frequent transactions than as a store of value like Bitcoin.

Transactions on the Litecoin network have lower fees are confirmed 4x faster.

Platform

Litecoin blockchain, hard forked from Bitcoin on October 2011, using PoW.

Current issues

Since Litecoin runs on a very similar blockchain to Bitcoin, it will eventually have similar scaling issues once the network grows to a certain size. However, the development community is trying to prepare for this by implementing scaling solutions early, such as Lightning Network.

More on Litecoin here.

Stellar (XLM)

Short explanation

Super fast digital payments

Longer explanation

Stellar Lumens, the coin operated by the nonprofit Stellar Development Foundation, can be used as currency similar to Bitcoin and Ripple. The platform is built for speed and ease of use, with transactions being completed in 3–5 seconds, and fees as low as $0.01

The goal of the Stellar Development Foundation (SDF) is to act as the world’s digital payment method by connecting users all over the world with banks and payment systems. The SDF plans to “fight poverty and maximise individual potential” by delivering their services primarily in regions where citizens have low access to banks, such as in Oceania.

They currently have a partnership with IBM, and have many well-known and influential people on their team.

Platform

Stellar blockchain operating with the Stellar Consensus Protocol (SCP).

Current issues

There are a few concerns around the level of security and decentralisation of the platform, but other than that, Stellar is in a great place. The team is very experienced and well-known, and they have some fantastic advisors on board.

More on Stellar here.

Tether (USDT)

Short explanation

Price equals 1 USD.

Longer explanation

Tether is a cryptocurrency pegged to the value of a US dollar, and is therefore referred to as a ‘stable coin’. This allows it to act as a USD substitute that can be moved between exchanges, instead of traders having to cash out for real dollars.

Platform

Tether blockchain, no consensus mechanism.

Current issues

Tether claims to keep a 1:1 reserve of real US dollars for every USDT released. It has had issues in proving the validity of this claim, which has caused many in the community to become skeptical of the company behind the token.

More on Tether here.

IOTA (MIOTA)

Short explanation

Internet-of-things (IoT) payments.

Longer explanation

IOTA is a fundamentally different type of crypto than most others. It is built on top of a directed acyclic graph (DAG) that they call a ‘tangle’ as opposed to a blockchain, which allows it to have zero fees and rapid transactions, as well as being easily scalable.

It is therefore suited for microtransactions of value or data between internet-connected devices.

Platform

IOTA tangle, using a small amount of PoW with each transaction.

Current issues

Since the technology is so new and different, IOTA needs to prove that their technology can perform the way they claim, as well as being resistant to hacks and bad actors.

There are also a few question marks around the team, with some in the community being concerned by the direction the team is taking.

More on IOTA here.

Monero (XMR)

Short explanation

Private, untraceable digital cash.

Longer explanation

Monero is a crowdfunded, open source and community driven privacy coin. Unlike Bitcoin, whos users aren’t fully anonymous, Monero is 100% private, secure and untraceable. It uses different algorithms to any other crypto that mix transactions and randomly generate fake addresses.

This means that it’s impossible to see the sender and receiver of a transaction, as well as the amount being transferred.

Platform

Monero blockchain with PoW consensus.

Current issues

The technology and team behind Monero are very sound. The project has been around for a long time and the team are all volunteers. However, due to the high level of privacy in Monero, it attracts a lot of hackers, criminals and others trying to evade the law, and is therefore being more frequently associated with these sorts of activities, which hurt its future prospects.

Payment – Winds of Change for Acquirers


Europe has a fragmented card acquirer market with around 400 acquirers accepting cards at millions of POS terminals, on the internet and mobile. From 2010, domestic card acquirers face significant competition both from foreign cross-border card acquirers and PSP processors becoming acquirers.

Contactless form-factors (e.g. Apple Pay, Samsung Pay, Android Pay), digital scheme wallets (e.g. MasterPass, Visa Checkout), new security requirements (e.g. 3D-Secure 2.0, tokenisation security) and legal authentication requirements (e.g. RTS SCA) are constant challenges for the card acquirers.

In addition, more digital payment service providers compete with card acquirers. They offer the acceptance of IBAN-based digital payment services (e.g. iDEAL), online wallets (e.g. PayPal, Amazon Pay) and prepaid account services to merchants.

Both the payments industry and competing card-less payment service providers benefit from the European legal framework for border-less payment services (e.g. PSD2) and a unique IBAN-based bank payments infrastructure (e.g. SCT, SDD, SCTINST).

Driven by connected consumers, modern retailers intend to offer omni-channel retailing services. Retailers demand omni-channel payment acceptance services from their supporting acquirers, both for cards and card-less digital payments.

Rethinking Capitalism With the Blockchain


It’s easy to think of capitalism as being an ever-present cultural artifact since most of us have grown up in countries where capitalism is the leading political and economic template. But capitalism as an ideology, and as a cultural manifestation, is a relatively recent phenomenon whose origins were violent and turbulent.

We are a trading species and haggling and opportunity seeking is part of the definition of being human. Almost every society has engaged in this form of activity from time immemorial. But in the late 17th century, and especially in England, something occurred which resulted in a departure from the norms that had prevailed for governing society for close to four thousand years.

Previously, religion provided the roadmap for morality, and hard work was promoted as the pathway to virtue. Royalty ruled over countries and provided order to their territories, which were constantly under threat. So remaining in power also meant engaging in war.

When taxes failed to meet the costs of war, King James the First, being the largest landowner in England, decided to increase his revenue by giving exclusive licenses for the production of a product, a trade or even a government service. This led to the construction of monopolies and in 17th century England, there were monopolies for almost everything from coal, bricks, food, and even belts and buttons.

But what King James, and monarchs after him, had not bothered to consider was the effect this was going to have on the culture of their society. As an increasing number of people tried to compete for these monopolies, the competition began to challenge submission. A growing number of new landlords, members of trading companies and cloth manufacturers began to gain a voice in the way the country was being run.

Juxtaposed with this transition was the English Civil War. Following the execution of King Charles the First, the monarchy was replaced by the Commonwealth. In a short span of 30 years, merchants and manufacturers went from being subjects to public personages with political power. Economic grievances thus became political issues and competition was seen as the sister of innovation. Gradually, the established hierarchy started to crack as new entrepreneurs began to emerge making society more fluid in the process.

The result was a departure from the old ways of thinking which ignited commentary, debate and explanations. As the traditional order was overturned, people began to change their ideas about fundamental values. Previously, change to the order was regarded as blasphemy. But the growing prosperity offered by capitalism encouraged individuals to take risks, question the status quo, challenge authority, and be less fearful of innovation and novelty.

Today, this might seem almost like common sense. But this mode of thinking was the result of the birth of capitalism. It was a renegade mode of thought that gave an attitude to the way men and women thought, and challenged the values, habits and modes of reasoning of the past. It was fraught with opposition, was the bedrock of revolutions in almost every developed country, including the Industrial revolution, and has defeated Socialism, Marxism, Communism or any other kind of ideological ‘ism’ till date.

As the centuries rolled on, capitalism spread like a prosperity juggernaut and in doing so, changed our mindsets and ingrained the concept of free markets and profit maximization as natural law. We believed the economists who preached it from their podiums and policy makers who used it as a yardstick for policy construction.

But just as King James, blind sighted by short-term gain, failed to see the cultural ramifications of capitalism, we too as a society have been oblivious to the cultural impacts of capitalism as we pursued our hedonistic objectives – both as individuals and societies, especially in the past few decades.

Capitalism’s Waltz With Debt

Following the second world war, advanced economies in the West installed a ‘state-administered’ version of capitalism where economic growth coexisted with social and political stability. For almost three decades, this version of capitalism became the gold standard of government and remains the nostalgic fodder for politicians’ campaigns.

But by the end of 1970’s, this formula for success began to crumble with the outbreak of the oil embargo and the Iraq-Iran war. As oil prices began to soar, industries began to suffer and the newly elected governments in the US and the UK realized that they needed to find radical new ways to create economic growth to stay in power.

One of the ways they responded to this crisis was by privatizing industries, a move that is now referred to as Reagan-Thatcherism. The strategy was simple – If companies and households could not earn their revenue as they did before, they could lend their way to it. As public services were privatized, economic decision making was taken from government and handed to Wall Street.

As time went on, this process was amplified. When globalization began to take manufacturing jobs, high-paid skilled jobs were replaced by low-wage jobs in the service industries. Wages stagnated and people began to earn less than they did before.

In the process of finding a solution, governments once again turned to the commercial banks and relaxed lending restrictions. Even if wages were static, people could borrow money and maintain a certain lifestyle. As a result, the ability to manage society and economics slid gently from the control of the state to the commercial banks and financial markets.

The cultural ramifications were that debt-based capitalism became a norm and an increasing amount of importance was given to growth and consumerism. We went from being ‘citizens’ to ‘consumers’. Free market policies and regulations that would aid in providing more debt (see the repeal of the Glass-Stegall Act) were one of the main tenets of macroeconomic policy.

The result is something we all know too well and which we are still recovering from – In 2008, our debt-based capitalistic system collapsed under the weight of unsustainable loans, as our hedonistic pursuits become collectively unsustainable.

How did we get into this mess? How did we go from using capitalism as a way of escaping dictatorial doctrines to a society that was wasteful, indifferent and voracious? How did we not see this cultural change in which having more and consuming became paramount to anything else? The more money, freedom, leisure and luxury we got, the more we wanted.

One of the main reasons for this was the overall acceptance of contemporary free market capitalistic theories and the policies and models that were based on these theories. Free market economic models (and the policies that are based on it) are based on two main theories – the Rational Expectations Theory (RET) and the Efficient Markets Hypothesis (EMH).

These two theories work in conjunction. The RET states that the expectations of players in a market are formed on the basis of the information that they have and their past experiences. According to this theory, stock prices reflect all the information regarding a stock. Thus, by using the stock price as a proxy, we have access to all the information regarding a stock on the market, and can make rational decisions based on our expectations.

If someone makes a bad decision, then it is offset by someone who makes a good decision. The market is thus in a constant state of efficiency where the price of a share intrinsically incorporates all the relevant information. As a consequence, markets are in a state of equilibrium (EMH). We might have a shock now and then but the market always goes back to its natural state, which is that of equilibrium.

Our faith in these theories has resulted in accepting that the bad actions of one economic agent would be offset by the good actions of another. As more debt was offered to us, we accepted it as it was now the norm. In the process of handing over responsibility to the ‘other’, we believed in the banks, bought their complex debt-based financial instruments (CDOs, CDSs, etc.) and listened to the bastions of the system as they preached about its benefits from their pulpits.

These increasingly complex financial instruments have contributed to the development of a far more flexible, efficient, and hence resilient financial system than the one that existed just a quarter-century ago. After the bursting of the stock market bubble in 2000, unlike previous periods following large financial shocks, no major financial institution defaulted, and the economy held up far better than many had anticipated” – Alan Greenspan, the Chairman of the Federal Reserve, (2005).

Those who challenged the status quo were ostracized from academia and markets, while the players in the economy were happy to go on taking debt and serendipitously advance towards a false sense of prosperity, leaving the hard business of understanding the macroeconomics of the system to people who were elected to do so.

But following the crisis, we need to take a step back and question this reality and the abilities of these economic bastions. We need to ask ourselves if the entire structure of analysis and the level of understanding of the experts needs to be questioned. This statement was best summarized by the Queen of England when she visited the LSE in 2007 and asked the economists in the room a very simple question,

“Why did no one see this coming?”

Thus, conducting a review of economic dogmas necessitates a review of the very basics, i.e., RET & EMH. More importantly, it requires a change in mindset and asking the right questions. Consider this – If our economy is supposed to be based on patterns of equilibrium, how does it explain a capitalistic system’s obsession with constant growth? Think about it – If you work in a company or are creating one, then the primary objective is to grow. Every company is constantly trying to expand, or buy out or merge with another company. It seems that it is never happy where it is and even if a company wishes to remain constant, its competitors will force it to move.

So if this state of entropy is the natural state of affairs, then why do we use equilibrium-based economic models to witness economics and pass public policies (monetary and fiscal)? We can extend that line of questioning and even challenge the RET – If all decisions are rational, then why do people engage in philanthropy? From a personal objective perspective, it would seem to be the most irrational thing to do.

In spite of these abhorrent divergences from reality, we continue to pass policies and enact measures based on analyses done using DSGE (Dynamic Stochastic General Equilibrium) models. It’s like the equivalent of bringing a turtle to a rabbit race.

Not questioning these fundamentals has been one of the primary causes of our addiction to debt and our laissez-faire attitude that has allowed banks to get bigger and more entrenched in every aspect of policy making. Therefore, what is required is a revisit to the very fundamentals on which we base our understanding of the economy.

We need to move from equilibrium-based models to entropy-based ones. Equilibrium can exist in an economy, but it is a temporary state. The natural state of an economy is entropic due to the constant exchanges and decisions being made by agents and actors in the economy. In short, we need to move towards complexity economics.

Complexity economics was devised based on this understanding of entropy and is a field that is gaining increasing prominence today. In a recent speech, Andy Haldane, the Chief Economist of Bank of England stated it is necessary for the bank to base its models on complexity science as it allows us to integrate complex, adaptive networks. Using these kinds of models, economic policy would be based on dynamic complex network analysis and behavioral modeling, thus giving us a template that is more suited to modeling reality.

The blockchain’s role in all of this

In the past few years, commercial and central banks have been toying with the blockchain owing to its operational efficiencies. In a recent report, the Centre for International Governance Innovation (CIGI) stated that G20 countries should create a central bank blockchain consortium, a la R3CEV.

The blockchain is many things to many people. But at its heart, it is an engine of transparency. While it is irrational to think of the blockchain as some kind of panacea that will be the solution to our current economic malaises, it is nevertheless a useful tool that can be used with other financial technologies to offer us more clarity of our capitalistic system. And this clarity is required today if we are to use capitalism to escape from a coterie of rulers, as we did in the 17th century.

This issue needs to be discussed today as enter an era where banks, academics and public institutions push us towards a cashless economy. Becoming a digital economy comes with benefits, but also comes with increased risk, owing to the speed, size and interconnectedness of the financial system. And one of the ways we can ignite this conversation is by leveraging the transparency that is provided by new financial technologies, especially the blockchain.

Transparency is a lop-sided issue in today’s financial markets, for as we transition to a cashless economy transparency seems to be a one-way street. As customers and citizens become digital avatars, banks and government institutions now have greater amounts of highly granular data with stark levels of detail.

But peculiarly, consumers, on the other hand, are not privy to the same amounts of transparency when it comes to the financial operations of banks and public governing bodies. A review of some of the scandals that have unfolded in the past three months highlights the need for two-way transparency:

It is, therefore, urgent that we ascertain what kind of an economic reality we are headed towards before any infrastructural changes are put in place. Or else, the spread of a crisis in a hyper-connected digital economy will be faster and more violent than before.

The blockchain’s transparency is however only part of the equation. Transparency can be illuminating, but to transform transparency to clarity still requires effort. While the blockchain allows us to see what is going on, it would make no sense to use this information as an input to models based on equilibrium. If we are to truly leverage the potential of the blockchain and use it to define macroeconomic policies that are more representative of reality, it has to work in conjunction with complexity economics:

(Blockchain’s Transparency) + (Economic models based on Comp. Economics) = Clarity of Capitalistic system.

As we move into a more digital world with faster technological evolution providing strong headwinds of change, it is important to realize that adapting to this change will not simply be a case of investing in the new tool or updating one’s skillset. Capitalism has always been a renegade, whose greatest impacts have been born out of conflict and change. At every turn, this has required that tough questions be asked, and our notions and conceptions be rewritten.

If we are to continue growing with hedonistic sustainability, we need to better understand capitalism. The unison of complexity economics and the blockchain is a step in that direction and will entail the creation of new cultural forms, institutions and a new vocabulary for education. But with a better understanding of capitalism, people in democracies can play a much more positive and vigorous role in shaping their economic institutions.

There would be no capitalism without a culture of capitalism and there would be no culture if the existing ideologies were not challenged and overcome. At a time when information is so abundant that we can get the answer to any question, the real responsibility becomes asking the right question. If we fail to ask these questions and leverage the power of decentralization and transparency, we risk starting a conversation with the next generation by beginning with an apology.

Blockchain


Blockchain is a distributed database that maintains a continually growing list of records that can be verified using hashing techniques.

Blockchain implementations have a handful of defining characteristics, it’s:

  • write-once;
  • append-only system (meaning records in the database cannot be changed, records can only be added to the ledger);
  • distributed;
  • replicated in multiple locations;
  • crypto-secured through a public or private key infrastructure;
  • uses hashes.

The hash functionality is particularly important as each individual transaction is hashed into the chain, and each block, which contains a bunch of transactions, is also hashed, which links it to the previous block. The moment anyone tries to change a transaction, everyone who has access to the chain would know immediately that it’s been tampered with because the hash wouldn’t match.

This creates a platform where multiple parties can share data, but all have proof that past records have not been changed. It’s quite a remarkable platform, but it’s in the very, very early stages of maturity.
