Cryptocurrency forks play a significant role in the development and evolution of blockchain technology. Crypto forks occur when a blockchain network undergoes a split, resulting in the creation of two or more distinct chains, each with its own sets of rules and often its own cryptocurrencies. This division can happen through different types of cryptocurrency forks, namely hard and soft forks.

Understanding blockchain forks is an essential element for those interested in understanding and/or trading cryptocurrencies. They represent pivotal moments in the blockchain's journey, where decisions are made, new features are introduced, and disagreements are resolved. By comprehending the concept of cryptocurrency forks, investors, users, and developers can navigate the landscape of digital currencies more effectively.

Crypto forks not only provide opportunities for innovation and technological advancements but also hold implications for the broader community. They can spark debates, divide communities, and even impact the market dynamics of cryptocurrencies. 

What is a soft fork?

A soft fork is a type of cryptocurrency fork that generally introduces backward-compatible changes to the blockchain protocol. Unlike hard forks, soft forks do not require all participants to upgrade their software to continue using the network. This means that users can choose whether or not to adopt the new features or rules implemented by the soft crypto fork.

For example, a soft fork that increases transaction speed doesn’t require everyone to upgrade their software. If you don’t upgrade your software, however, you will not be able to take part in any future transactions using the new feature (ie: faster transaction speeds). 

These types of forks are a great way for new changes to be implemented without creating an entirely new cryptocurrency. Below we review two notable soft forks.

The SegWit fork

In 2017, the Bitcoin blockchain underwent a soft cryptocurrency fork known as the Segregated Witness (SegWit) Bitcoin protocol update. It aimed to address the scalability issue of the Bitcoin network by separating transactional data from signature data, allowing for more transactions to be included in each block

Before the SegWit upgrade, Bitcoin's protocol was both more expensive and slower, with transactions costing about $30 each and taking around an hour to complete. The inventors of the SegWit change recognized that signature data accounts for 65% of a transactional block. As a result, SegWit proposed moving the effective block size from 1MB to 4MB.

The motivation for this increase was to separate or delete the signer data from the transactional data on every blockchain block, allowing for greater transaction throughput per block.

With the new fork, the old Bitcoin blockchain was able to accept both new 4MB and 1MB blocks at the same time. The soft fork enabled the existing nodes to validate the new blocks via a clever engineering approach that formatted new rules without breaking existing ones.

The Byzantium and Constantinople soft forks

These were two consecutive soft forks on the Ethereum blockchain, implemented in 2017 and 2019, respectively. These forks introduced new features to the blockchain's protocol, such as improved security and privacy, as well as changes to the Ethereum Virtual Machine (EVM).

Soft forks have a relatively lower impact on the blockchain and crypto community compared to hard forks. Since they are backward-compatible, users who don't upgrade their software can still participate in the network, although they may not be able to take advantage of the new rules and features introduced by the soft fork. 

Soft forks generally aim to improve the efficiency, security, or functionality of the blockchain without causing a complete split in the network.

What is a hard fork?

Hard forks are more disruptive and result in the creation of two separate blockchains, each with its own set of rules and cryptocurrencies. A hard fork occurs when there’s a fundamental change to the blockchain, such as upgrading one of its core technical components (ie: blocksize). 

This requires everyone who uses that blockchain to upgrade their software or else they will no longer be able to participate on the network. Users can also opt to be a part of both networks that result from the blockchain split. For example, Bitcoin Gold is a hard fork of Bitcoin that aims to decentralize the mining process offering two very different use cases.

Hard forks are a common occurrence in the cryptocurrency industry, with many big cryptocurrencies being the product of a successful hard fork. Below we explore two notable hard forks. 

The Bitcoin Cash fork

The Bitcoin Cash fork is a prime example of a hard fork. In 2017, following a disagreement within the Bitcoin community about the future of the original cryptocurrency, a group of developers and miners got together to form a new and improved version of the cryptocurrency's network known as Bitcoin Cash. The Bitcoin Cash hard fork was implemented with the upgraded blockchain utilizing a new version of the underlying code, and a new cryptocurrency labeled BCH.

The most significant change to the Bitcoin Cash network was the block size increase to 8MB, allowing for faster transaction speeds, more transactions to get verified at once, and lower transaction fees. The new version of the network also increased the difficulty to ensure the security of the network would not be compromised. In March 2022, the block size limit was increased to 32MB.

There have been many Bitcoin forks over the years, with Bitcoin Cash and Litecoin being the two most well-known.

The Ethereum Classic fork

Ethereum Classic originated from a hard fork of the Ethereum blockchain in 2016. The fork occurred due to a disagreement over how to handle a security breach in the DAO (Decentralized Autonomous Organization). Ethereum Classic maintained the original blockchain, while Ethereum (ETH) continued on the new forked chain.

A hard fork can have significant implications for the blockchain and its community. They often result from divided opinions or visions within the community, leading to the creation of new cryptocurrencies. A hard fork can bring about new features, address scalability concerns, or resolve contentious issues, but it can also cause community divisions and introduce volatility into the market.

Market effects and price volatility

Crypto forks can have a significant impact on the cryptocurrency market, often leading to price volatility and market reactions. The effects are driven by a combination of factors, including investor sentiment, community support, and the perceived value of the newly forked cryptocurrencies.

1. Forks can impact cryptocurrency prices by creating uncertainty and divergent market expectations. Prior to a fork, investors may exhibit cautious behavior, leading to increased selling pressure as they seek to secure their holdings or reallocate their assets. This uncertainty stems from concerns about the viability and market reception of the forked cryptocurrencies.
2. Market reactions to major forks have been observed in various instances. For example, during the Bitcoin Cash crypto fork in 2017, the anticipation and subsequent launch of the new cryptocurrency caused a surge in trading volumes and price volatility. Similarly, when Bitcoin Cash itself underwent a contentious hard fork in 2018, resulting in the creation of Bitcoin SV, the market witnessed significant price fluctuations and increased trading activity.

These reactions reflect the market's response to the perceived value and potential utility of the forked cryptocurrencies. Investors and traders assess factors such as community support, technological enhancements, and the ability to solve existing challenges. Depending on the market's reception, prices can experience both short-term spikes and long-term shifts as market participants adjust their positions and reassess their expectations.

It's important to note that the impact of crypto forks on prices and market dynamics can vary. While some forks generate significant market buzz and trading activity, others may have a more muted effect. Factors such as the size and influence of the community, the level of support from industry players, and broader market conditions all contribute to the overall impact of a fork on cryptocurrency prices.

Navigating the market effects of crypto forks requires vigilance and a deep understanding of the underlying factors at play. Investors and traders should carefully assess the potential risks and rewards associated with forked cryptocurrencies, keeping in mind the volatility and market reactions that can accompany these transformative events.

What to do when a fork is announced

When a cryptocurrency announces an upcoming fork, a rule of thumb in the crypto space is to wait for the dust to settle before making any big decisions. Keep in mind that sometimes forks can be contentious and not everyone will agree on the path forward, meaning that there may be a lot of confusion and volatility in the coming days as people react.

 In conclusion

A hard fork is when a blockchain network is split into two resulting in two unique blockchains with their own cryptocurrencies. A soft fork is when a blockchain simply upgrades or incorporates new features and allows users to decide whether they would like to continue using the old version or upgrade their software protocol to make use of the new features.

Either way, cryptocurrency forks are a common occurrence in the blockchain space and have been the start of many different networks. The most iconic hard forks include the likes of Litecoin, a hard fork from the Bitcoin network, Ethereum Classic, a hard fork from the Ethereum network, and Bitcoin Cash, a hard fork of the Bitcoin network.

Both soft and hard forks allow innovation within the blockchain space to evolve, making space for new features, more efficient means of executing an action, and other chain improvements. A hard fork in particular can shed light on new innovations without creating a blockchain network from scratch.

The age old question, when will all the Bitcoins be mined, has been on everyone's mind at least once and today we are going to go over exactly how long it will take to mine all Bitcoins.

There are a few chapters we need to cover first. For one we need to look at Bitcoin’s total supply, followed by the halving mechanism that Satoshi Nakamoto himself implemented, and then we can set about working out when the last Bitcoin will be mined. Sound good? Dive in and join us for the ride.

Bitcoin’s total supply

When Bitcoin was first announced to the world in a whitepaper in 2008, the public was introduced to a new kind of monetary system. Unlike the fiat system that all countries operate off, these cryptocurrencies presented a digital answer that could navigate value around the world in seconds and didn’t rely on any banks, financial institutions or governments to operate them. 

Created as a response to the 2007 - 2009 global financial crisis, the mysterious entity known as Satoshi Nakamoto chose to also make the currency deflationary. Unlike its fiat counterpart, Bitcoin was created to increase in value over time, proving to be a viable store of value. Written into its code was the fact that only 21 million Bitcoin will ever exist, ensuring that the new age currency would have a deflationary nature to it. 

Of the 21 million BTC that will ever enter circulation, as of May 2021 a total of 18.7 million have entered the market. This accounts for roughly 89% of the total supply of Bitcoin, which might lead one to believe that the end is nearer than we think. However, think again.

The halving mechanism

‍

Another ingenious idea that the great Satoshi Nakamoto incorporated into the nuance payment system is the halving mechanism. Through the use of blockchain technology, every 210,000 blocks, or roughly four years, a halving mechanism is automatically implemented into the system which reduces the mining rewards (also known as block rewards). This part gets a little technical, so let’s recap. 

All transactions on the blockchain are stored in blocks which are chronologically linked to one another through the process of mining. Miners on the network verify and execute all Bitcoin transactions, and in doing so receive a fee, known as the miners reward. When Bitcoin was launched in January 2009 the miners reward was 50 BTC, however through the halving mechanism, every 210,000 blocks this reward halves. Twelve years later the miners rewards for verifying the transactions and adding a new block to the blockchain is 6.25 BTC. 

This thereby controls the amount of new Bitcoin entering circulation. As fiat currencies are printed and minted, cryptocurrencies are mined. The Covid-19 pandemic saw many countries print more money to distribute to its people and in turn boost the economy, however the long term effects of this can be devastating due to rising inflation and the decrease in value on a global scale. Bitcoin, however, due to the controlled nature of the deflationary currency is set to increase in value. 

How long will it take to mine all the Bitcoins?

‍

Now that we’ve covered the basics of Bitcoin’s total supply and the halving mechanism controlling the influx of coins entering into circulation, it’s time to establish how long it will take to mine all Bitcoins. 

Based on the table below, we can see exactly when the next halving is due to take place (in 2024), when the miners reward will halve again to 3.125 BTC. While the amount of BTC received for mining a block decreases, bare in mind that the value undergoes significant increases. After that the next halving mechanism is due to go into effect in 2028, followed by another in 2032.

As you’ll notice, the halving in 2032 will be responsible for mining the last chunk of the 99.21872% of the total BTC ever to exist. This leaves 0.78128% remaining. Due to the nature of the halving mechanism, it is believed that the very last Bitcoin will only be mined in 2140. 

In answering the question on how long it will take to mine the last Bitcoin, the answer is an estimated 119 years. Which, facing the cold hard truth, we are unlikely to witness in our lifetime.

‍

Time to buy Bitcoin?

Considering that the cryptocurrency has witnessed gains taking it from $0.003 to roughly $55,000 in just over a decade, consider what the Bitcoin price might be in the next ten years, or twenty, or 100? Whether you’re buying to invest or buying to trade, Bitcoin has proved time and time again to be a worthy investment. Consider bagging yourself some BTC with the convenience of the Tap app. The app allows you to not only buy the original cryptocurrency, but to sell, store and spend it as you please too. If you’re wondering when the last Bitcoin will be mined, it’s probably time to tap into the future.

In this article, we’re exploring the most recent addition to the list of supported cryptocurrencies on the Tap App, one of the highly esteemed top 20 cryptocurrencies based on market cap, Algorand (ALGO).

What is Algorand (ALGO)?

Algorand is a decentralized blockchain platform that supports the development of a wide range of dapps (decentralized applications). The platform has been used to create dapps across industries like real estate, copyright, microfinance and more. Launching the same month as its ICO, the Algorand mainnet officially went live in June 2019. 

The Pure-Proof-of-Stake (PPoS) network was created to improve efficiency and transaction times within the crypto space, as well as reduce transaction costs. With no mining (due to the PPoS consensus), Algorand represents a more sustainable and energy-reserving contribution to the space. 

A unique aspect of the platform is that as new ALGO enter circulation with the creation of each new block, the newly minted coins are distributed to everyone who holds a certain amount of ALGO in their wallets. 

While the project is relatively new, it has received the backing of big names and has seen impressive company interest. In June 2021, Arrington Capital bet $100 million on the platform after launching a fund supporting initiatives building on Algorand, while fintech infrastructure provider Six Clovers launched a cross-border payment system on the platform. 

The platform was also selected to host the Marshall Islands CBDC. 

Who created Algorand?

The blockchain platform was created by Silvio Micali, a highly regarded contributor to the crypto space and recipient of the 2012 Turing Award. The MIT computer science professor was recognised for his fundamental contributions to “the theory and practice of secure two-party computation, electronic cash, cryptocurrencies and blockchain protocols.” 

The Algorand whitepaper was co-authored by Stony Brook University professor Jing Chen.

When first conceptualised in 2017, Micali wanted to create a platform that not only provided digital transactions but also tracked assets like titles and property. The platform also allows for the creation of smart contracts (decentralized digital agreements) and tokens. 

How does Algorand work?

The Algorand platform is divided into two layers: layer 1, responsible for ​​ensuring the network’s security and compatibility, and layer 2, responsible for more complex developments. 

Layer 1 supports asset creation, smart contracts, and atomic swaps between assets while layer 2 is reserved for more compound smart contracts and dApp development. These two layers allow the network to process transactions more efficiently, with simple transactions taking place on layer 1, while more complex smart contracts are executed off-chain. 

Through the pure proof of work consensus, the two-phase block production is conducted through a propose and vote system where users who stake ALGO are randomly selected to validate and approve each block as it is created. Stakers only need to hold 1 ALGO in order to generate a participation key necessary to become a Participation Node. 

These nodes are coordinated by Relay Nodes which are not actively involved in the verification process but are responsible for facilitating communication among the Participation Nodes.

The more of the native cryptocurrency a user holds, the more likely they are to be selected. This consensus ensures that the platform is secure, decentralized and able to process transactions in seconds as opposed to minutes (as on other networks).

Algorand is able to process over 1,000 transactions per second (TPS) and validate transactions in less than five seconds.

What is ALGO?

ALGO is the native token to the Algorand platform. As the newly minted coins are distributed to all users holding ALGO (whether on an exchange or in a non-custodial wallet) and not just the nodes verifying transactions, holders of the token are able to earn a 7.5% annual percentage yield (APY). 

A total of 10 billion tokens were minted, with roughly 6.8 billion in circulation at the time of writing. These tokens are gradually entered into circulation through predetermined distribution channels. The token distribution for ALGO is as follows:

• 3.0 billion. To be injected into circulation over the first 5 years, at first via auction.
• 1.75 billion. Allocated to participation rewards.
• 2.5 billion. Allocated to relay node runners.
• 2.5 billion. Allocated to the Singapore-based Algorand Foundation & Algorand, Inc.
• 0.25 billion. Allocated to end-user grants. 

How Can I Buy ALGO?

If you’re interested in accumulating this leading blockchain token, you can do so effortlessly through the Tap app. As part of a new string of supported tokens, Tap users will now be able to buy, sell, trade and store the cryptocurrency that everyone is talking about. 

When exploring the world of blockchain and its endless possibilities, it’s likely that you’ve come across the term dapps. But what are dapps? In this piece we explore the concept, decipher their place in the industry, and look at several networks that currently support them.

What are dapps?

Decentralized apps, or dapps as they’re more commonly known, are applications that are built on top of peer to peer decentralized networks. Instead of being built on one computer, with one single entity in control, dapps utilize a network of computers based anywhere around the world. With multiple computers operating and maintaining the network, dapps are able to incorporate many streams of content consumption, be it providing content, trading or consuming it. 

The advantages of dapps

Compared to standard web apps, like Twitter or Uber, these apps can handle multiple users but only one authority has control over the backend of the app. Dapps provide a more decentralized and secure approach. So while Uber connects passengers to drivers through the app for a portion of the payment, dapps essentially allow the drivers and riders to connect directly, taking no payment for the connection.

Another advantage to the world of dapps is that all transactions are transparent and stored on the blockchain of the network it is built on. Dapps also need a token to operate, which enhances the security of both the dapp and the transactions taking place. Typically dapps are also open source, allowing other developers to view the code and further drive development in the industry.

The disadvantages of dapps

As with anything in life, there are also disadvantages. As the world of dapps is still in its infancy stage, the user base is relatively low. When it comes to blockchain based projects, the more users a network has the higher functioning the network is. Unfortunately, many dapps still have a relatively low user base decreasing the functionality, however that doesn’t speak for all of them. As the blockchain and crypto worlds continue developing and reaching wider audiences, both the usability and users will increase. 

Another disadvantage is the potential vulnerability to hacking. As most dapps are created using open source smart contracts, this leaves them open to potential probing from hackers. This isn’t a given, however it has happened in the past that hackers found weaknesses in the network and were able to conduct illicit activities through them. 

How many dapps are there?

According to a dapp monitoring website, State Of The Dapps, there are currently roughly 3,500 dapps in the industry. These are spanned across a wide range of networks, including the likes of Ethereum, EOS, TRON, NEO, Steem and more. The website further reports that over $257 million has passed through the dapps industry in just twenty four hours (at the time of writing). Dapps also cover a broad range of subjects, with dapps catering to industries like energy, exchanges, finance, gambling, games, health, identity, insurance, marketplaces, media, property, security, social, storage and wallets. The most widely of which are finance, security and exchanges.

A look into Ethereum dapps

The most widely used network to create dapps on top of, Ethereum has over 2,700 dapps built on its network. Ethereum was the first network designed to provide a blockchain platform on which developers could build their own decentralized applications. Ethereum was also the first network that allowed developers to create and execute their own smart contracts, an essential ingredient to the making of dapps. 

According to DappRadar, the three biggest dapps currently on the Ethereum network are DeFi projects and an exchange. Coming in at first place based on its current market cap is Uniswap, a defi protocol (exchange) that facilitates the trading of cryptocurrencies. Uniswap has an estimated 48,950 active users. Also dabbling in the world of DeFi, the second largest dapp on the Ethereum network is compound, a protocol that allows users to lend and borrow crypto. The third largest is MakerDAO, a smart contract that facilitates user interaction with the Dai stablecoin system.

A look into EOS dapps

Similar to Ethereum but with fewer transaction fees, the Entrepreneurial Operating System was designed to provide developers with a platform on which to build their blockchain based endeavours. As the second largest platform on which dapps are currently created, let’s explore the three largest dapps currently operating on the network. Coming in first place is Joule, a dapp which promotes financial inclusion and social change through determining the Global Popularity Index in real time. The next two entries both fall into the DeFi category, being Defibox and VIGOR.

The power of dapps

While many dapps are still in the experimental phase, there is also a large amount of money circulating in the industry and millions of users indicating a promising market. Thanks to dapps’ wide use range and the amount of innovation in the industry at present, the dapp industry is likely to continue growing and become a permanent fixture in many peoples’ lives, whether crypto inclined or not.

When it comes to understanding Bitcoin, an important aspect to get familiar with is the mining of it. As we explore what is Bitcoin mining and how does it work, we aim to empower you with a greater understanding of how the network functions as well as how blockchain technology facilitates the operations on the backend. Adaptable to many industries outside of the cryptocurrency space, blockchain technology is at the forefront of the tech revolution. Understanding how Bitcoin mining works is the first step to understanding the technology too. 

What does Bitcoin mining entail?

Forget about shovels and dark tunnels, Bitcoin mining is the decentralized manner in which transactions are verified and new coins are minted. Mining also plays a vital role in the maintenance and operation of the network, ensuring both the security and integrity of the platform at all times. The actual process of Bitcoin mining involves miners using sophisticated computers to solve complex cryptography problems.

The Bitcoin network is made up of a number of nodes (computers) and miners around the world that communicate with each other and constantly share the updated record of the blockchain. The blockchain stores all transactions in a transparent and immutable manner, allowing anyone to view it from wherever they are, however, no one can make any changes.

How does Bitcoin mining work?

Let’s say someone in Japan wants to send money to someone in America through the Bitcoin network. The user in Japan would initiate a transaction from their chosen wallet, pay a network fee, and execute the transaction. This transaction would then enter a mempool, a pool of transactions that are waiting to be confirmed. Typically mempools work on a “first come first serve” basis, however, users can opt to pay a higher network fee should they want to push their transaction further forward in the que. 

Miners will then pick up a number of transactions in the mempool and attempt to solve the complex cryptographic puzzle that will lead them to mining the block. The first miner to solve the puzzle is rewarded with the task of verifying the transactions and adding them to a block, in turn receiving the network fees as well as the block reward. Each block on the Bitcoin network can hold 1MB of transactional data. 

While many miners will attempt to solve the math problem using their own resources, only one miner will be successful. This has sparked a conversation, largely fueled by Elon Musk’s recent tweet, over the electricity consumption it takes to mine Bitcoin. Tesla, the company that Musk heads, recently withdrew Bitcoin from their payment options due to the un-eco friendly manner in which the network operates, as it goes against their company ethos. 

Once the miner has verified the transactions, ensuring that the wallet addresses exist and that there are available coins in the senders’ account, all the transactions are added to a block. This block is then added to the blockchain after the most recently added block, each block indicating the hash code of that block and the block before. This ensures that no one can tamper with the order or edit the content of any blocks. 

The user in America will then receive a notification confirming that their wallet has received the BTC, however it will need to go through three confirmations (sometimes more) before being accessible. Each confirmation is represented by a new block added to the blockchain following the block with your transaction. 

What is a block reward?

The block reward is a monetary reward given in Bitcoin to the miners for adding a new block to the blockchain. It is also the process used to mint new coins and in the process enter them into circulation. Alongside the block rewards, the miner responsible for adding the new block to the blockchain will also receive the network fees of each transaction verified within that block. 

This makes Bitcoin mining a lucrative endeavour, however, the start up costs are significant and your success rate will depend on the equipment, power, and cost of electricity in your area.

What is the halving mechanism?

As Bitcoin will only ever have 21 million coins released, Satoshi Nakamoto created a mechanism that ensures the slow release of coins over time. This is called the halving mechanism, and it automatically executes every 210,000 blocks. During the halving the block reward is halved, ensuring that the cryptocurrency remains deflationary in nature.

This means that for every 210,000 blocks added to the blockchain, the block reward given to the miners will halve. To date there have been three halvings in Bitcoin’s history, with the last one taking effect in May 2020. The block reward is currently 6.25 BTC for every block added to the blockchain.

Want to enjoy the benefits of Bitcoin without mining?

There’s another way to get in on the Bitcoin action without the use of sophisticated hardware and high electricity consumption. Users can tap into the Bitcoin network by buying BTC directly from their phones through the Tap Global app. The process is simple, takes minutes, and allows you to own your very own BTC. Through the Tap app users can also trade, store and spend their cryptocurrency, with advanced technology facilitating the process on the backend to ensure smooth and secure trading.

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.

Decentralized vs centralized

The cryptocurrency market is made up of decentralized exchanges and centralized exchanges.
