Learning the friendly way

What started off as a joke has become an international phenomenon with a market cap that ranks it among the top 10 cryptocurrencies (not to mention price gains). As we explore what Dogecoin is, let's take a look at where the digital cash network came from, why the cryptocurrency became such a sensation and how it compares to Bitcoin.

Leading the way in the meme-based movement, Dogecoin has become the most unlikely of leaders in its field as it trades at a very attractive price. Everyone from investors to run-of-the-mill Internet users has followed the hype and invested in this meme-inspired altcoin.

Did you know that Dogecoin has more DOGE in circulation than Ethereum and Litecoin combined? Let's dive in to understand the true value behind this Internet meme-inspired cryptocurrency

Who created Dogecoin?

Dogecoin was created as a joke cryptocurrency in 2013 and is based on a Shiba Inu dog meme circulating at the time. Two developers, Billy Marcus and Jackson Palmer got together to create the cryptocurrency to poke fun at Bitcoin, which turned out to be a lot more than that almost a decade later.

What is Dogecoin?

Dogecoin is a peer to peer payment system with its native cryptocurrency, DOGE, acting as the medium of exchange. The cryptocurrency was created in December 2013 through a hard fork off of the Litecoin network. The cryptocurrency has no limit on the maximum amount of coins and currently has over 131 billion DOGE in circulation.

While a popular option as a digital cash payment method, the cryptocurrency is most commonly used as a tipping system to reward quality content on social media platforms like Twitter and Reddit. Working in a similar way as cash would in a financial transaction.

What's triggered Dogecoin's surge?

The self-proclaimed "Dogefather" and Tesla CEO Elon Musk has contributed to Dogecoin's recent success with his tweets about the cryptocurrency making news headlines around the planet. His tweets have had a significant effect on the cryptocurrency's price as published on the CoinMarketCap website.

With a similar mining style to Litecoin, Dogecoin is a popular option when it comes to trading cryptocurrencies.

How does Dogecoin work?

Using blockchain technology, Dogecoin facilitates digital transactions in a transparent and mutable way. Hard forked off of the Litecoin network, Dogecoin uses the same Scrypt technology in the Proof-of-Work protocol. Unlike Litecoin, however, the cryptocurrency can execute transactions in 1 minute.

Users simply need to create a wallet in order to store DOGE, from where they can either send and receive the cryptocurrency or simply store it. DOGE works similarly to other cryptocurrencies in this regard.

In the last year, investors have seen high gains as the celebrity-endorsed hype surrounding the cryptocurrency increased its value. As interest grew in the Shiba-meme token, so too did its market cap, pushing Litecoin out of the top 10 biggest cryptocurrencies and edging closer to Ethereum (currently in second place).

The Dogecoin foundation

In 2014 members of the Dogecoin team created a not-for-profit foundation to oversee project development and direction. This dissipated over the years and was recently relaunched in 2021 with several key new members and an inflated market capitalisation.

While co-founder Billy Markus and Dogecoin's core developer Max Keller remain on the board, two new additions have been made with the likes of Ethereum founder Vitalik Buterin as well as Jared Birchall, the manager of Elon Musk's family office. 

The team meets on a monthly basis to discuss issues relating to the virtual currency, with each member taking responsibility for various aspects. Markus is responsible for overseeing the community and memes while Keller will function as the cryptocurrency technical advisor.

Buterin will serve as the blockchain and crypto advisor and Birchall as the financial and legal advisor (representing Elon Musk).

Dogecoin's following

From its initial launch, Dogecoin has had a spirited and loyal following. In its early days, the community raised funds for high profile events, like sponsoring a NASCAR driver and sending the Jamaican bobsleigh team to the 2014 Olympics.

To date, a number of high profile celebrities have put their name behind the coin, most notably Elon Musk and billionaire Mark Cuban. Musk was responsible for several waves in the crypto market in 2021, causing substantial boosts and dips in the capitalisation of the market. Most notably in May, after a tweet from Musk stating only "How much is that Doge in the window?" The DOGE price increased by 11% in mere hours. 

While Dogecoin was not created to be a store of value, the Dogecoin price increases certainly brought about tons of media attention and healthy returns for investors.

Dallas Mavericks owner Mark Cuban is also a huge fan, celebrating the cryptocurrency for being "the one" when it comes to a digital medium of exchange. In 2021, the NBA team started accepting Dogecoin as a payment option for merchandise and ticket sales, incorporating blockchain into the main league.

What is the difference between Dogecoin and Bitcoin?

While both cryptocurrencies are designed to provide a medium of exchange, they differ in a number of ways. For starters, they both use the same Proof-of-Work mining concept which is based on miners solving complex mathematical problems in order to mine new blocks and control the supply.

Different from each other, the Dogecoin network can process transactions 10x faster than Bitcoin (1 minute vs 10 minutes for BTC). They also have varying inflationary statuses, with Bitcoin being deflationary in nature due to its 21 million coin cap while Dogecoin is highly inflationary as it has an unlimited supply. 

While Bitcoin can be held as a store of value, Dogecoin is less supported in this area due to its lack of maximum supply and the fact that millions of DOGE are entering circulation each day. DOGE however, is better suited to being a medium of exchange.

While Bitcoin has a strong following around the world, there is a significant Twitter and Reddit community punting the coin and encouraging traders to buy the cryptocurrency. From internet meme to international top 10 traded cryptocurrency, Dogecoin has an impressive history when it comes to market value.

How do I buy Dogecoin?

In just nine months the cryptocurrency has become a legend of sorts in the crypto community (including Reddit), moved into the top 10 cryptocurrencies based on market cap, and grown 5,000% in value.

Should I immediately pour my life savings into it? Probably not. But if you're looking to add the cryptocurrency to your cryptocurrency investment portfolio, look no further than the Tap Global platform. DOGE is one of the latest cryptocurrencies to be onboarded on the mobile app. 

Since Bitcoin came into existence in 2009, the use of the term fiat currency has significantly increased. But what is a fiat currency? In this article, we take a look at the origins of the term and why it's called fiat currency, how it functions, some examples of fiat, and what threat crypto has posed to it. Let’s dive in. 

What is fiat money?

Fiat money is money declared as legal tender by the government and acts as a nation's currency. The term "fiat" is a Latin word and loosely translates to "by decree" which is an authoritative order with the force of law. The government declares fiat money legal tender by decree. 

Fiat money acts as a national currency and is printed by the government. Citizens can use it for payments of goods and services, facilitating trade in the area. 

In 2020, all currency traded internationally was officially declared as fiat money. This means that the value of fiat money isn't linked to anything physical like gold or silver but rather to the faith and credit of that government. All fiat currencies are operated by a central authority, in most cases central banks, that carry out a nation's monetary policy and are responsible for controlling its money supply.

Until 1971, foreign currencies were fixed in value relative to the US dollar whose worth was based on an amount set by Congress expressed in terms of gold ounces. That year President Richard Nixon did away with that system completely in what was called  "the Nixon shock." 

Fiat currency vs fiat money

Fiat currency and fiat money essentially refer to the same thing. Both represent the government-issued currency used in a country or region. There are around 180 different types of fiat currencies in use globally. Examples of fiat include the United States dollar, Canadian dollar, Euro, and British pound sterling, or Japanese yen. 

The value of one fiat currency in relation to another is referred to as the exchange rate.

Fiat money vs commodity money

Fiat money is essentially the opposite of commodity money. The major difference between the two stems from their intrinsic value. In general, a commodity currency has an intrinsic value that comes from what it is made of, a physical commodity such as gold or silver coins.

Fiat currency does not have any intrinsic value and only exists because a country's government or country's central bank says it can be exchanged for other goods with equal value.

How did fiat currencies come into existence?

All money is a certificate of debt. In the past, if someone needed to be paid back for something at a later date, they would receive an IOU that said how much was owed to them and when it could be collected. 

Bartering system

For example, let's say a farmer traded 2kg of flour today for ten pumpkins come harvest time. 

To keep track of this arrangement and to avoid forgetting or getting confused about what was owed, the person providing the flour would be given a piece of paper indicating that it could be exchanged for pumpkins after harvest. This piece of paper effectively becomes worth ten pumpkins and could be used to trade for milk, bread, or any other goods. 

The bartering system only allowed trade to happen when each person had what the other one desired. To make it more efficient, people started using something that everyone wanted as a basis for trading, a physical commodity. For a long time, rocks that shine (gold) served that purpose.

Gold to coins

However, weighing gold for each transaction was complicated, so governments started to create identical gold coins made from a specific amount of gold. They put raised lines around the edge of every coin as proof that no one shaved off any bits of gold, making trade easier since everyone knew how much each currency was worth.

Introduction of banks

However, gold is heavy to carry and became dangerous to keep on oneself at all times, so people started storing their gold in bank vaults. Bankers would provide a certificate as proof that each person owned a certain amount of gold, which could later be redeemed at the central banks for gold. This shifted the legal tender from gold to a piece of paper. 

Gold to paper money

As the government was typically the largest holder of gold, it began printing its own paper currency that people could use to trade for gold at the national treasury, representing the origins of the gold standard. However, people stopped going to redeem the paper for gold and instead just used the paper itself. 

Supply/demand logistics

At this stage, a currency's value was still tied to the value of gold, which had some problems in itself. Firstly, if a new source of gold emerged or another country suddenly released a significant amount of gold, the currency's value would drop. Secondly, anyone could manipulate the price of gold thereby throwing the currency's value. 

Fiat money emerges

Hence, the gold standard was dropped in the 1930s. Instead, the currency became worth the amount printed on the piece of paper instead of the gold it represented. IOUs once again became the official source of money and held value "by decree" instead of based on an underlying asset. 

Is fiat money still relevant today?

Since the advent of cryptocurrencies (digital currencies not managed by a central authority or government), the way we think about money has changed significantly. While mainstream adoption of these digital currencies continues to grow (several countries have declared Bitcoin as a legal tender) the use of fiat money isn't going anywhere. 

Fiat currencies still hold a significant place in the global economy and will continue to do so for a long, long time. And while some grow skeptical of governments' power to mint new fiat money or the central banking system in general, it's unlikely that fiat currencies are going anywhere. 

CBDCs

One new development that is gaining popularity is the CBDC, merging the worlds of fiat currency with digital currencies. The Central Bank Digital Currency is maintained and operated by central banks, uses blockchain technology to operate, is pegged to the value of the local fiat currency, and works in parallel to the national currency. Eradicating price volatility, the CBDC uses a more secure means of distributing and facilitating the movement of fiat currency. 

While cryptocurrencies are unlikely to replace fiat currencies anytime soon, it's worth noting how significantly the concept of money has changed over the last century and considering how things could change in the future for fiat currency as we know it.

‍

In a world where every crypto project claims to be 'revolutionary,' Ethereum actually walks the talk, successfully changing how we think about the internet, finance, and digital ownership.

Conceived by Vitalik Buterin in 2013 and launched in 2015, Ethereum expanded the possibilities of blockchain technology beyond simple currency transactions, introducing a world where apps can run exactly as programmed, without censorship or third-party interference.

While Bitcoin introduced us to digital money, Ethereum brought us programmable money (and much more, for the record). You may have heard it being referred to as the world's computer, this is because it allows developers to build and deploy decentralised applications (dapps) that can transform industries from finance to art, gaming to governance.

In this comprehensive guide, we'll explore what makes Ethereum special, how it works beneath the surface, and why it continues to be at the forefront of the blockchain revolution. Whether you're completely new to the concept or looking to deepen your understanding, we'll break down everything from smart contracts to NFTs, the shift to Ethereum 2.0, and what the future might hold for this groundbreaking technology.

What is Ethereum? Explained simply

Think of Ethereum as a global, open-source platform for decentralised applications. While Bitcoin is primarily designed to be digital money, Ethereum is built to be a development platform, a foundation upon which developers can create new applications that no single entity controls.

The easiest way to understand Ethereum is to compare it to your smartphone's operating system. Just as iOS or Android provides a platform for developers to build mobile apps, Ethereum provides a platform for developers to build decentralised apps. These apps run on a network of thousands of computers around the world rather than on centralised servers owned by Google or Amazon.

Ethereum is often described as a "world computer" because it's essentially a massive, distributed computing system that belongs to everyone and no one at the same time. Unlike traditional computers controlled by individuals or companies, this world computer runs programs (called smart contracts) that execute exactly as written, without the possibility of censorship, downtime, or third-party interference.

As a "second-generation blockchain," Ethereum took Bitcoin's innovation (a decentralised ledger) and added programmability to it. This advancement opened up a universe of possibilities beyond simple value transfer, allowing for complex financial instruments, digital ownership records, and even autonomous organisations to exist on the blockchain.

How Ethereum works

At its foundation, Ethereum builds on the same blockchain technology that powers Bitcoin. A blockchain is essentially a chain of blocks, where each block contains a record of transactions. What makes it special is that this record is maintained by thousands of computers (nodes) around the world rather than by a central authority like a bank.

What are smart contracts?

Where Ethereum truly shines is with smart contracts. Think of smart contracts as digital agreements that automatically execute when predefined conditions are met, like a vending machine that delivers your soda when you insert the right amount of money. These contracts are:

• Self-executing: They run automatically when conditions are met
• Immutable: Once deployed, they can't be changed
• Transparent: Anyone can verify the contract's code
• Trustless: You don't need to trust a third party; the code is the guarantee

What is Ether (ETH)?

Ether (ETH) is the native cryptocurrency of the Ethereum network. It serves two important purposes:

1. As a digital currency that can be sent instantly to anyone, anywhere in the world
2. As "fuel" for running smart contracts and transactions on the network

What are gas fees?

This brings us to gas fees. Just as your car needs gas to run, Ethereum operations need "gas" to execute. Gas fees are small amounts of ETH (measured in “gwei,” a subunit of ETH) paid to network participants who contribute computing power to validate transactions. These fees help keep the network secure and prevent spam or infinitely running programs from clogging the system.

When the network gets busy, gas prices rise because there's limited space in each block, making Ethereum transactions sometimes expensive during peak times.

What are token standards?

Ethereum (truly) revolutionised the cryptocurrency ecosystem with its token standards. These are frameworks that define how digital assets behave on the network. 

Ethereum’s token standards are like architectural blueprints in the sense that they provide a consistent design that developers can follow to ensure every structure (token) integrates seamlessly into the broader city (Ethereum ecosystem).

The 3 main Ethereum token standards:

• ERC-20: Created the template for fungible (interchangeable) tokens, making it easy to create new tokens without building a new blockchain (although adoption still depends on design and demand). This standard powers thousands of tokens, including major stablecoins like USDC and most DeFi tokens.
• ERC-721: ERC-721 was the first standard to define non-fungible tokens on Ethereum,, however today there are additional NFT-related standards, such as ERC-2981 for royalties. This standard made possible the digital art revolution, powering collections like CryptoPunks and Bored Ape Yacht Club.
• ERC-1155: ERC-1155, introduced by Enjin, is ideal for games and metaverse applications where users need both fungible and non-fungible currencies and unique collectibles. 

These standards transformed crypto by creating massive interoperability, all of a sudden tokens built on Ethereum worked instantly with hundreds of wallets and exchanges. This "plug-and-play" functionality dramatically accelerated innovation and adoption.

Ethereum's token standards have become so influential that even competing blockchains implement compatibility with them, essentially making them the industry's universal language for digital assets.

The Ethereum ecosystem

Ethereum's true power lies in its vibrant ecosystem that continues to expand in exciting ways:

Decentralised applications (dapps) 

These are applications built on Ethereum that connect users and providers directly without any intermediary organisations controlling the service. Some popular examples include:

• Uniswap: A decentralised exchange for trading tokens
• Aave: A lending and borrowing platform
• OpenSea: A marketplace for digital assets

DeFi (decentralised finance) 

Perhaps Ethereum's most transformative impact has been in finance. DeFi applications recreate traditional financial services like lending, borrowing, and trading, but without banks or brokers. 

Instead, they use smart contracts to create protocols that operate exactly as programmed. By April 2025, the total value locked in DeFi protocols has grown to tens of billions of dollars, demonstrating significant adoption of these new financial tools.

NFTs (Non-Fungible Tokens) 

NFTs represent unique digital assets - from artwork to music to virtual real estate. Unlike cryptocurrencies, where each coin is identical, each NFT has distinct properties that make it one-of-a-kind. 

This technology has revolutionised digital art by enabling verifiable ownership and scarcity for digital creations, leading to an explosion in creative expression and new income opportunities for artists.

DAOs (Decentralised Autonomous Organisations) 

DAOs are internet-native organisations collectively owned and managed by their members. They operate based on rules encoded in smart contracts: members vote on decisions, and the outcomes are automatically executed by code. From investment clubs to charitable foundations, DAOs are reimagining how we organise and collaborate.

Ethereum 2.0 and The Merge

In 2022, Ethereum underwent its most significant upgrade since launch, transitioning from Proof of Work (PoW) to Proof of Stake (PoS) consensus with an event known as "The Merge." This transformation addressed several key challenges:

• Environmental impact 

The original Ethereum (like Bitcoin) used Proof of Work, requiring massive computing power and electricity consumption. The switch to Proof of Stake reduced Ethereum's energy usage by approximately 99.95%, addressing one of the biggest criticisms of blockchain technology.

• Scalability 

Ethereum's popularity led to network congestion and high transaction fees. The move to PoS laid the groundwork for future scaling solutions, including sharding (a method of splitting the network into parallel segments to increase transaction throughput dramatically).

• Staking opportunities 

Under the new system, users can "stake" their ETH (lock it up as collateral) to help secure the network and earn rewards, typically 3-5% annually. This provides a way for ETH holders to earn passive income while contributing to network security.

Ethereum vs other blockchains

Ethereum vs Bitcoin 

While both use blockchain technology, they serve different purposes:

• Bitcoin: Primarily a store of value and medium of exchange
• Ethereum: A platform for building applications and executing smart contracts

Ethereum killers

Several competing platforms have emerged, each claiming to solve Ethereum's challenges:

• Solana: Offers higher transaction speeds and lower costs
• Cardano: Focuses on academic research and formal verification
• Polkadot: Created by an Ethereum co-founder to enable cross-chain interoperability
• Avalanche: Emphasises high throughput and fast finality

Of course, these benefits can come with trade-offs in scalability and ease of use.

Ethereum's advantages 

Despite strong competition, Ethereum maintains significant advantages:

• First-mover advantage and massive developer community
• Highest security due to its large, distributed network
• Most extensive ecosystem of applications and tools
• Strong network effects and brand recognition

Risks and considerations

While Ethereum offers exciting possibilities, as with anything, it's important to understand the risks:

Price volatility 

ETH, like most cryptocurrencies, experiences significant price swings. Since 2015, it has seen both 90% drawdowns and 1000%+ gains. 

Security concerns 

While the core Ethereum protocol has proven secure, smart contracts can contain bugs or vulnerabilities. High-profile hacks have resulted in hundreds of millions of dollars in losses over the years.

Regulatory uncertainty 

Governments worldwide are still determining how to regulate cryptocurrencies and decentralised finance. Regulatory changes could impact certain applications or use cases.

Technical challenges 

Despite improvements, Ethereum still faces challenges with scaling to meet global demand, maintaining decentralisation, and providing a seamless user experience.

The future of Ethereum

Ethereum's roadmap continues to evolve with several key developments anticipated:

Scaling solutions: "Sharding" is expected to significantly increase Ethereum's capacity by splitting the network into parallel segments, potentially enabling thousands of transactions per second.

Layer 2 growth: Solutions built on top of Ethereum like Optimism, Arbitrum, and Polygon continue to gain traction, offering lower fees and faster transactions while maintaining security by settling transactions on the main Ethereum chain.

Industry adoption: Major companies from finance to entertainment are exploring Ethereum for applications ranging from supply chain tracking to royalty distribution. Enterprise adoption is expected to accelerate as scalability improves.

Web3 integration: The vision of Web3 - a more decentralised internet where users control their own data and digital identities - is being built largely on Ethereum. This could fundamentally change how we interact with online services.

How to buy Ethereum (ETH)

If you'd like to become involved in the Ethereum platform and own the digital asset that fuels the network, you will need to purchase ETH through a trusted crypto exchange platform and set up an Ethereum wallet. 

Offering a secure and convenient solution, buying and selling ETH through your Tap app is easier than you might think. With several payment options and a quick verification check, you can start trading, using or hodling ETH from your unique wallet in a matter of minutes. 

Final thoughts: why Ethereum matters

Ethereum represents one of the most ambitious technological experiments of our time - an attempt to rebuild the very foundations of how we transact, collaborate, and create online. By removing intermediaries and enabling direct peer-to-peer interactions, Ethereum challenges traditional power structures and creates new possibilities for human coordination.

Whether Ethereum ultimately fulfils its vision of becoming the settlement layer for a new, decentralised internet depends on how it addresses its remaining challenges around scalability, usability, and regulation. But its impact is already undeniable, having spawned entire industries from DeFi to NFTs and inspired a generation of developers to rethink what's possible with blockchain technology.

The most fascinating aspect of Ethereum may be that we're still in the early chapters of its story. Like the early internet in the 1990s, we can see the potential but can't yet imagine all the ways this technology will transform our world in the decades to come.

Decentralized finance, or "DeFi," refers to financial services that provide many of the same features as traditional banks - like earning interest on your money and borrowing from others - but without middlemen who take a fee or charge interest, paperwork, or privacy trade-offs. A chartered accountant and Blockchain do not have much in common, but they are starting to as DeFi and FinTech take over. I

nstead of relying on financial services like banks, users can utilize smart contracts on blockchain. Cryptocurrencies ensuring even more ease of use for DeFi users, providing the hottest speeds, fees, and transparency. Defi and digital currencies are growing in popularity thanks to the perks of Blockchain technology. Let us get more into the concept and how it caters to a larger audience.

The aim and use of DeFi

Decentralized finance is the future of financial services, and it's already here. The aim of DeFi is to provide a decentralized financial services platform that is open and accessible to anyone in the world, using tech like crypto to help advance the everyday life of anyone and any business willing to give decentralization a try.

In the past decade, we've seen a rise in peer-to-peer lending platforms such as Lending Club, Patreon, BTCJam, and an explosion of digital currencies such as Bitcoin and Ethereum.

All of these developments have taken us one step closer to the decentralized future of finance that we've been dreaming about, but there's still more work to be done.

What's wrong and how can DeFi fix it

Many institutions in the financial sector are slow and expensive when it comes to providing basic services like payments. Online lender contracts can charge interest rates as high as 30 percent, and the global remittance industry charges fees that can be as high as 12 percent.

These fees and delays mean some of the most vulnerable individuals of our society are paying the highest prices for financial services when they need them most. While the traditional financial system can be slow and expensive, it doesn't have to be this way. Decentralized finance (DeFi) is an emerging category of services where trust intermediaries such as banks are replaced with cryptographic code and smart contracts, which reduces costs for everyone involved - especially when it comes to international payments.

DeFi is a new category of services that are globally accessible and built on top of blockchain infrastructure, without any charge or barrier to entry. It's also much more secure than traditional financial systems because the technology used isn't connected to a central server that can be hacked. DeFi users smart contracts applications to ensure ease of use and instant transfers of information and funds.

Your money is always yours; it's just moving from one smart contract to another. No permission from an intermediary is required in order to use it. All you need to do is have a cryptocurrency wallet, computer or mobile device, and internet connection like everyone else using DeFi services today.

DeFi isn't coming, it's already here

When you ask yourself, "where is DeFi going?", the answer is simple: everywhere. DeFi can be used from every corner of the world, and it's already available today. Innovation at its finest.

DeFi services are not theoretical. They're already being used by real people today to make real asset payments, earn interest on their digital savings, and borrow money from both friends and strangers, all without ever going through a bank or traditional financial institution. Whether you are investing, a money maker, or an asset holder, the shift to DeFi is inevitable.
Blockchain technology provides the first-ever opportunity for these separate building blocks to come together in order for the entire financial system to work seamlessly without any intermediaries, so it will only get better with time. From an economic standpoint, DeFi offers better rates and all the perks of FinTech. Cryptocurrency assets like Ethereum have seen plenty of investment opportunities arise as DeFi and Blockchain merge.

DeFi pros and cons

In order to get a complete picture of what DeFi is, it's important to understand all the good and bad parts that we are facing now. So let's dive into the details.

DeFi pros:

• The interest rate on savings and money lending is relatively high, just as it would be without intermediaries.
• Financial services are more accessible than in traditional bank systems because there aren't any barriers to entry, like non-existent internet infrastructure or bank account fees.
• Transaction and disruption times are much faster because DeFi transactions can move directly from peer to peer without having to go through intermediaries.

DeFi Cons:

• Some transactions might not be as private due to the public records of smart contracts on a blockchain (keeping that in mind, transparency is always beneficial). This however increases security because fraud or reversal can't happen.
• Access to DeFi services can be limited if you live in a part of the globe where these services aren't supported or don't have high enough adoption rates, as compared to traditional banking systems in developed countries. Regulator issues may also occur.
• There isn't a built-in mechanism for handling consumer disputes between peers because the technology simply wasn't designed with this function in mind.
• It's difficult to understand what you're getting yourself into when joining a DeFi service, since it varies from one application to the next and is based on new technology. This doesn't have to be the case in the future.
  

As of now, it's still the early days for DeFi and there are some challenges to overcome before we can look at it as a real alternative. There's still a lot of work to be done, but it will all pay off in the end.

As all things “metaverse” continue to dominate headlines, the virtual world has established itself as front and centre of mainstream media. Decentraland provides a virtual world where users can buy, sell and trade unique assets and engage in interactive apps and peer-to-peer communication alongside in-world payments. The world of Decentraland has seen impressive growth, and it’s about time you learnt about it. 

At its core, Decentraland is a virtual reality platform that allows users to create, experience, and monetize in-house content and applications. Built on the Ethereum blockchain, Decentraland utilizes two main tokens on the platform, LAND and MANA. 

LAND arenon-fungible (NFT) tokens that provide ownership rights to the digital real estate (land parcels) while MANA is the in-house currency that facilitates the sale of LAND and other goods and services available on the platform, like customising one's avatar, for instance. MANA also allows holders to vote on policy updates, subsidies for new developments, and land auctions. 

Decentraland was designed to provide users access to ​​”new artistic medium, business opportunity, or source of entertainment.” The virtual space is made up of 90,601 individual land parcels, each measuring 16m x 16m (256 square meters), and assigned to particular co-ordinates in its “metaverse”.  Each space is assigned to a LAND NFT which records the ownership. 

LAND owners can then develop the land as they please, with several marked districts varying in size and theme. Holders can then lease out the land or provide paid experiences through the creation of animation and interactions experienced on their particular virtual real estate.

Who Created Decentraland?

Decentraland was created by the Decentraland Foundation, founded by ​​Esteban Ordano and Ariel Meilich in 2015, and holds the intellectual property rights as well as maintaining the platform. Before launching, the foundation, which still holds 20% of the total MANA supply, created a decentralized autonomous organization (DAO) allowing the users to make governance decisions. 

In 2017 the project underwent a successful ICO, raising the equivalent of $26 million at the time. These funds were used to drive future operations. 

How Does Decentraland Work?

The core function of the Decentraland network is to track ownership of land parcels, while users engaging in the platform are required to hold MANA in order to participate. 

Through a system of smart contracts each land parcel is tracked on the consensus layer, with each parcel’s own coordinates, owner, and a reference to the content within the parcel. 

The content layer then holds the specifics for each parcel, including the all static audio and visuals, the placement and behavior of items, as well as P2P interactions such as gesturing, voice chat, and messaging. There is then a real-time layer that facilitates all the social interactions of the user avatars.

Decentraland also hosts a marketplace where users can create scenes and wearables and manage and exchange LAND tokens, priced in MANA. 

What Is MANA?

MANA is the governance and in-house currency for the Decentraland ecosystem. With a total supply of of 2.19 billion MANA, roughly 600 million MANA have been burned in LAND transactions bringing the previous total supply down substantially. 

MANA facilitates the platform’s aim of providing a customizable and shared virtual reality space that connects users around the world.

How Can I Buy MANA?

If you’d like to join the metaverse and become a part of the Decentraland virtual community, you can simply buy MANA directly from your Tap account. As part of a string of newly supported cryptocurrencies, MANA is now available for trade on the Tap app, allowing users to buy, sell and spend MANA as they please. 

Cryptocurrencies have been revolutionary in their pursuit of merging decentralization with the finance sector. The industry has grown to provide many alternative options to the traditional financial products available, with most of them at a fraction of the cost. Cryptocurrencies have digitized the way we view, use and manage our funds, and it's only the beginning of the digital assets revolution.

What is cryptocurrency?

Cryptocurrency is the blanket term used to describe any digital asset that utilizes blockchain technology or distributed ledger technology to operate. The first cryptocurrency that came into existence was the Bitcoin network, created in 2009 by the mysterious Satoshi Nakamoto.

The cryptocurrency was designed to provide an alternative monetary system to the traditional banking sector, free from politics. Instead of a central authority, Bitcoin operates using a decentralized network of computers that work together to transact and verify any financial transactions using the Bitcoin protocol. For the first time ever people could manage their money without having to rely on a centralized institution.

Since Bitcoin's success, many other cryptocurrencies have emerged, some providing a revised solution to the digital cash system Bitcoin created, while others have brought innovation to the crypto space.

The Ethereum blockchain, as an example, provides the industry with a platform on which developers can create decentralized apps (dapps) merging the app concept with the decentralized nature of blockchain technology.

Cryptocurrency vs traditional currencies

Traditional currencies, also known as fiat currencies, are operated by government institutions while cryptocurrencies are maintained through a network of computers following a specific protocol. While a Federal Reserve typically sits behind a fiat currency, the key players in a cryptocurrency's existence typically involve:

• Core developers, responsible for updating a network's protocol
• Miners, responsible for validating and executing transactions
• Users, the people using the cryptocurrency
• Exchanges and trading platforms, facilitating the trade of these cryptocurrencies.

While governments have free control over printing new money, most cryptocurrencies are created with a hard cap. For instance, Bitcoin was designed with a maximum limit of 21 million coins, meaning that there will only ever be that number in existence. Not all cryptocurrencies have this hard cap though, Ethereum has an infinite supply due to the nature of the platform and the cryptocurrency.

Unlike fiat currencies, Bitcoin and many other cryptocurrencies were designed to be deflationary, with the necessary factors in place to ensure that the value of the currency increases over time (based on simple supply-demand economics).

Another pressing difference between cryptocurrencies and fiat currencies is that cryptocurrencies are still undergoing regulatory processes. While they are not illegal to trade (in most countries), they are not yet considered to be legal tenders (again, in most countries). Regulators around the world are working on a legal framework in which cryptocurrencies can operate in mainstream markets.

How do cryptocurrencies work?

Now that we've covered the basics on what is cryptocurrency, let's take a look at how these digital currencies actually function. First and foremost, through the use of blockchain technology. While not all cryptocurrencies use this technology, most do and we will use it as an example (as the concept is roughly the same).

Blockchain technology explained

Blockchain is best explained as a digital record-keeping system, or a distributed database. All transactions made on the network are stored in a transparent manner for anyone to see, with no way to edit or omit any of the information. All data is stored in blocks, which are added chronologically to a chain, hence the name.

A block will contain information relating to every cryptocurrency transaction, like timestamps of when it took place, the sending and receiving wallet addresses, transactional hash, and amounts. Depending on their size, blocks typically store data for a few hundred to a few thousand transactions. Blocks will then also hold a block hash, a unique identifying number associated with the block, and the hash of the previous block to prove its order.

When companies incorporate blockchain technology into their businesses they will typically use a private network where the information is only transparent to certain users. This is referred to as a "permissioned" blockchain, different from a "permissionless" blockchain used for Bitcoin and other cryptocurrencies.

Cryptocurrency transactions explained

While blockchain forms the backbone of a cryptocurrency network, miners facilitate the transactions. In a process called mining, cryptocurrency transactions are validated and executed, and through cryptocurrency mining new coins are minted. To make this easier to understand, we're going to use an example of Lucy sending Bitcoin to Jane.

From her Bitcoin wallet, Lucy will initiate a transaction to Jane, sending 1 BTC. After entering Jane's wallet address, she will confirm the network fees presented (these are paid directly to the miner for their time and effort), and execute the transaction.

The transaction will then enter a pool of transactions waiting to be executed called a mempool. Miners then compete to be the first to solve a computational puzzle, the winner of which will be rewarded with verifying and executing the next batch of transactions (cryptocurrency mining).

Confirming that each wallet address exists and each sender has the available funds, the miners will collect each of the network fees that the senders paid. The data from the confirmed transactions will then be added to a block and added to the blockchain right after the last published one. For adding a new block to the blockchain, the miner receives a block reward.

This block reward is based on the current rate, which is halved every 210,000 blocks (roughly every 4 years). This is how new Bitcoin enters circulation and the currency is able to maintain a deflationary status.

Jane will then receive a notification to say that she has received 1 BTC, and depending on her wallet will need to wait for 3 - 6 confirmations before being able to access the funds. Each confirmation is when a new block is added to the blockchain, which typically takes 10 minutes.

This process is typical of a proof of work network, used on networks like Bitcoin. This process is also the same whether you are buying crypto from crypto exchanges or sending to a friend.

The only time this differs is when using a cryptocurrency blockchain that utilizes a proof of stake consensus. In this case, instead of miners competing to solve the puzzle (requiring a lot of energy), validators will be selected by the network to conduct the verification process afterwhich this information will be verified and added to the relevant blockchain ledger.

The different types of cryptocurrencies

With tens of thousands of virtual currencies on the market, a number of subcategories have been created. While Bitcoin is a digital cash system providing a store of value and a medium of exchange, not all cryptocurrencies follow this structure.

Cryptocurrencies that are not Bitcoin are referred to as altcoins, (alternative coins), a term coined in the early days when new coins started emerging. Some altcoins are focused on providing heightened privacy, security, or speed while others are created for entertainment and leisure.

There are nine main types of cryptocurrencies, which we'll briefly highlight below:

• Utility, provide access to the platform service
• Payment, used to pay for goods and services within and outside of its network
• Exchange, native to cryptocurrency exchange platforms
• Security, where its usage and issuance are governed by financial regulations
• Stablecoins, digital currencies with prices pegged to fiat currencies
• DeFi tokens, digital currencies used on DeFi (decentralized finance) exchanges
• NFTs, non-fungible tokens representing unique identities that cannot be replicated
• Asset-backed tokens, where their underlying value is backed by a real-world asset

Another category that is gaining popularity around the world is Central Bank Digital Currencies, CBDCs. These digital currencies are operated and maintained by a central bank with the price pegged to the local currency.

What are the benefits of digital currency?

Cryptocurrencies are known for their fast and secure transactions, not limited by borders or government intervention. Below are several highlights that cryptocurrencies bring to the financial sector.

• Decentralized. Eliminating third parties and centralized authority, cryptocurrencies make the transfer of assets possible while reducing costs and time constraints.
• Security. Blockchain provides a transparent and immutable means of storing transactional data ensuring smooth and accountable operations.
• Deflationary. Most cryptocurrencies with a limited supply are designed to be deflationary in nature due to the decreasing supply mechanisms set in place. With basic supply-demand economics, a reduced supply and increased demand drive the price up.
• Reduced transaction fees. Cryptocurrencies provide a much cheaper alternative to sending fiat currencies across borders. With no need to exchange currencies and bypass several middlemen, cryptocurrencies are able to be sent on a peer-to-peer basis in a matter of minutes.
• Diversification. When it comes to investing, cryptocurrencies present a measure of diversification. Considering your risk tolerance and asset allocation, cryptocurrencies could be a part of your investment portfolio.

What are the risks associated with cryptocurrencies?

While there are plenty of benefits, as with any "new" asset class, there are risks to be considered too.

• Market volatility. Cryptocurrencies are prone to bouts of volatility with prices rising and falling dramatically in various frames of time.
• Market manipulation. Some cryptocurrencies might fall victim to a pump-and-dump scheme through no fault of the networks'. These are typically orchestrated by third parties.
• Theft. While blockchains can't typically be hacked, many cryptocurrency exchanges and wallets that don't utilize the necessary security measures can fall prey to hackers. To avoid this ensure that you always stick to a regulated platform with high-security measures.

How does one store cryptocurrency?

Cryptocurrency is stored in a digital wallet, similar to how one would store money at financial institutions only with cryptocurrency you are entirely in control of your funds. From the wallet you can make crypto transactions, store a wide range of cryptocurrency assets and hold your cryptocurrency investments long term.

Each cryptocurrency wallet is specifically designed to hold a certain type of cryptocurrency. For example, you cannot accept Bitcoin in an Ethereum wallet or send Bitcoin Cash to a Bitcoin wallet. Each wallet also comes with a set of public and private keys, the latter of which gives the holder access to the funds.

How to trade cryptocurrencies on cryptocurrency exchanges

Now that you understand what is cryptocurrency, let's cover how to enter the world of crypto assets. Entering the world of cryptocurrencies can be both exciting and rewarding. While we encourage every single person to conduct their own research prior to getting involved, once you're ready to start your journey into the cryptocurrency space, we're here for you.

Crypto exchanges

In order to buy any digital currency, traders will need to utilize cryptocurrency exchanges. These exchanges facilitate the buying and selling of crypto assets, and depending on the structure, often require users to offer some proof of identification before conducting any cryptocurrency transactions.

Decentralized vs centralized

The cryptocurrency market is made up of decentralized exchanges and centralized exchanges. The difference between the two is how they are operated, with centralized exchanges have a central authority. Typically, the centralized ones are more reliable and trustworthy as they require licenses which hold them accountable to certain standards within the financial sector. When looking to trade any digital currency, find an exchange that is regulated and licensed by a financial body.

The Tap app is a mobile app that allows users to buy, sell, trade, store and even earn crypto through a secure wallet infrastructure. Supporting a number of popular cryptocurrencies, users gain access to a wide range of markets. Fully regulated by the Gibraltar Financial Services Commission, the app uses top-of-the-range security technology to ensure that all data and funds are secured at all times.

Open an account

To engage in the cryptocurrency market all one needs to do is create an account. To open an account on Tap simply download the app from the App or Google Play store, enter the details required and complete the KYC process, an international requirement on all reputable digital currency platforms. Users will then gain access to a number of crypto and fiat wallets, with the ability to accumulate a wide range of cryptocurrencies.

From there, users can make cryptocurrency transactions, whether to friends also using the platform, external wallets or even external bank accounts for online payments, such as municipalities. The app offers a modern approach to banking services where funds can be used for real world payments.
