Learning the friendly way

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.

Investing centers around making gains off of your initial capital. When determining the potential gains one could make there are a number of variables one needs to consider, such as how much capital one has put into the investment and what returns are associated with that asset class.

This led to the creation of ROI (return on investment), a measure that allows anyone to calculate the net profit or loss of an investment in percentage form. 

What is return on investment?

All investments, including stocks, bonds, real estate, and small businesses, come with the goal of making more money than you put in. The money you earn over and above your initial investment is called profit. When discussing investment profitability, people often use the term ROI, meaning return on investment. This metric expresses the amount of net profit one can earn/earned as a percentage of what the initial investment was.

ROI can help you assess if buying property or investing in a business is worth it. It's also helped companies determine the value of adding new products, building more facilities, acquiring other businesses, advertising campaigns, etc.

ROI (return on investment) is the percentage of gain or loss on an investment relative to the total cost of the investment.  In other terms, it's a way to compare different investments in order to figure out which ones are worth pursuing. For example, you could calculate ROI to decide whether selling one stock and buying another would be a good idea.

While there is no limit to a return on investment theoretically, in practice, no investment is guaranteed to have any return. If your ROI is negative, it means you not only failed to make a profit but also lost some of your original investment. The worst possible outcome would be -100% ROI, meaning you completely lost your initial investment. An ROI of 0% signifies that you at least recovered the money you put in, but gained nothing beyond that.

While ROI is often used as a marker of profitability, it isn't foolproof. There are several limitations to calculating ROI as your only measure which include the time frame in which you will earn back your investment, inflation rates, how risky a venture is, and additional maintenance costs that may be incurred.

Calculating ROI terminology

Before we dive in, let's first cover some basic terminology.

Net profit or net income

Net profit is the amount of money left over after all operating costs, such as the cost of transaction costs or maintenance costs, and other expenses have been accounted for and subtracted from the total revenue. It is used to measure profitability. Net profit can also be called net income, net earnings, or the bottom line.

Total cost of investment

This figure will look at the amount of money invested in a particular investment.

How to calculate ROI: the ROI formula

The ROI formula is a simple equation that looks at the price change of the asset and the net profits (the initial cost of the investment minus its value when you sell it). When calculating ROI you would use this formula:

ROI = (Net Profit / Total Cost of Investment) x 100

To factor trading costs into your ROI figure, you'll use: 

ROI = ((Value of Investment - Cost of Investment – Associated Costs) / Cost of Investment) x 100

As an example, let's say you buy 5 shares of $100 each in Twitter, equating to $500. You sell them a year later for $150 each, equating to $750. Let's say you paid $5 commission on each trade, costing you $25 in trading fees. 

ROI = (($750 - $500 - $25) / $500) x 100 = 45%

This means that you made a 45% return on investment on that particular investment.

How to determine a strong ROI

A "good" return on investment is any number above 0, as this means you made some profit. However, the ideal ROI should be higher than what you could've earned had you chosen another investment (the next best thing). 

To compare this, investors often compare their earnings to what they could've made on the broader stock market or in a high-yield savings account. Using the S&P 500 as a control, over the past four decades it has made gains of around 7% (after inflation). An ROI is generally considered to be a strong one if it beats the stock market in the long term. 

It's always important to note that past performance does not equate to future results. Another pearl of wisdom to remember is that high rewards generally come alongside high risks. If an investment promises very high ROIs, consider this also means that it comes with high risks. 

Therefore, a strong ROI will vary depending on the investment's level of risk, your goals, and how much risk you're willing to take.

Where the ROI formula falls short

The main limitation of using this return on investment ROI formula as a marker of success is that it doesn't show how long it took to earn the money back. When comparing various investments, the time it takes to mature will have a significant impact on the profits you could earn.

For instance, a year loan versus a bond held for five years versus a property held for 10 years will all have varying ROIs once you've established how long it will take to earn the specified ROIs. 

In this scenario, the ROI calculations mentioned above skimp on the full story. It also doesn't account for risk. For instance, the loan repayments could be delayed or the property market might be in a slump, all affecting the potential profits earnable.

With many variables, it becomes harder to predict what the exact ROI calculation on an investment will be, so be sure to factor this in when using the return on investment ROI formula to determine how attractive an investment opportunity or business venture is. 

ROI alternatives

Although the return on investment doesn't consider how long you keep an asset, it's essential to compare the ROI of investments held for comparable lengths of time as a more clear performance measure. If that's not possible, there are a few other options.

Average Annual Return

Also known as annualized return on investment, this adjusts the ROI formula to factor in the timing. Here you would divide the ROI by the number of years you hold the asset.

Compound Annual Growth Rate (CAGR)

This option is more complicated but yields more accurate results as it factors in compound interest generated over time. 

Internal Rate of Return (IRR)

This measure factors in the notion that profits earned earlier outway the same profits earned later, taking into account interest that could've been earned and factors like inflation. This equation is quite complicated but there are online calculators one can use. 

Conclusion

A return on investment (ROI) is a formula used to calculate the net profit or loss of an investment in percentage form. The ROI calculation can present valuable information when investing capital or determining profitability ratios. The ROI equation looks at the initial value of one investment and determines the financial return. A negative ROI indicates that the investment returns were lower than the investment cost.

Cryptography is the process of converting messages into unreadable text so that only the intended recipient will be able to read them. Cryptography is responsible for the security, anonymity, and trust less transactions of digital currency. – entirely without the services of a financial institution.

We'll define cryptography as the study of methods to exchange sensitive information over an insecure channel in such away that only authorized parties can access it. In our case, this will be exchanging ownership of cryptocurrencies (which is represented digitally), or transferring ownership by signing digital messages.

A bit of history:

Cryptography dates back to the time when people began exchanging messages in forms other than face-to-face conversations(e.g., via written letters). The first known use of cryptography can be traced to Egypt, about 2000 years ago, during the reign of Pharaoh Thutmose III. Other known historical uses of cryptography are in the works of Julius Caesar, who used a simple cipher for messages between him and his generals.

The purpose of cryptography in crypto

A blockchain-based cryptocurrency needs some form of encryption to secure its money supply from being stolen by hackers or malicious software. It also allows for the anonymous transfer of funds between individuals without requiring a trusted third party, such as a bank or government institution. Cryptocurrencies are entirely based on cryptographic ideas.

Compared to cash transfers, cryptocurrencies do have another layer of security built into the blockchain: cryptography. The purpose of which is to validate transactions and prevent unauthorized access to the ledger by keeping all information inside a digital file that only authorized people can see. It's kind of like a physical vault (or safe) where you can keep all your money. But, unlike a physical vault, there's also no way to access the safe without a private key or password.

Usage of cryptography in Cryptocurrency

Cryptography is used in several different components of Bitcoin's security model, as well as in other cryptocurrencies.

Bitcoin addresses, which are used to receive and send funds between people on the blockchain, have both public keys and private keys. Only the owner of an address's private key can spend funds sent to the address, and only the owner of an address's public key will be able to receive them.

Every time you send or receive bitcoins, your transaction is signed with the appropriate digital signature using your private key. Since you can't share your private key with the person receiving your bitcoins, they verify that the signature is correct using your public key. The process of sending and receiving bitcoins between addresses is entirely anonymous and doesn't require any personal information (although there are ways to link transactions to identities).

Cryptocurrencies use public-key cryptography in order to prove ownership of addresses and transactions. This is done with a piece of data known as a digital signature, which is obtained using the sender's private key, and attached to the end of every transaction block along with other information about that block. Each new transaction has its own signature, verifying that the sender owns the address that is being used to send the funds. Since only the owner of a private key can create a digital signature for it, this provides a very strong guarantee that nobody else has sent their cryptocurrency to an address other than the one currently being spent from.

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.

ICO is an abbreviation for Initial Coin Offering, a term coined supposedly in 2013 yet only gained popularity in 2017. ICOs were created as a method of raising funds for cryptocurrency projects in a crowdfunding manner. When people partake in an ICO, through funding it, they receive "shares" of that project in the form of cryptocurrency tokens.

This method is set up to help new projects find funding to build their project, platforms, or products. It's very similar to investing in a start-up in the hopes of a project becoming bigger and better through your investment contribution.

Mastercoin was the first ICO recorded back in 2013, raising a grand total of 5,120 BTC. Shortly after, Ethereum followed, and in 2014 raised roughly $18 million to build their project. There is clearly a great deal of success to be seen through ICOs, so let's see what all the fuss is about.

ICO vs IPO vs IEO

Let's look at IPOs, or initial public offerings, to learn more about where ICOs originated.

Similar to ICOs, IPOs were created as a way of gaining capital to better the businesses' infrastructures. While they are similar to a crowdfunding aspect,the primary distinction is in how investors are rewarded. IPOs will offer their investors shares, while ICOs offer digital currencies that can be used within their ecosystems or can be sold when the price increases.

Now that we understand how ICOs and IPOs work, let's discuss the differences when it comes to IEOs, or Initial Exchange Offerings. Again, this is another method used to raise funds for upcoming projects, but there are some key aspects that make IEOs different to IPOs and ICOs. While IEOs are also a crowdfunding method in the cryptocurrency industry, they use an exchange. Anyone can generally buy tokens from an ICO page, whereas IEOs use exchanges as the distribution mechanism.

In order to take part in an IEO, you must be a registered user of the exchange that the project is utilizing. While IEOs may be more transparent, they do push us towards a more centralized approach. There are also IDOs, Initial Dex Offering, Dex standing for decentralized exchange (increasing the data privacy aspect), but that's a topic for another day.

How they work

So now we know what ICOs are and how they differ from their counterparts, but now let's delve deeper into how ICOs actually work. As stated, ICOs are a way for cryptocurrency projects to raise money. When a project decides to launch an ICO it will generally underline the sale dates, the participation rules, and the buying process.

Usually, investors will need to choose currencies they are happy to accept in exchange for their tokens, such as Mastercoin accepting Bitcoin. There are some ICOs who will also accept fiat currencies as payment.

The projects' core purpose, its timeline, and how much money is needed to succeed should be released in their whitepaper. If the project does not raise enough money to meet the minimum funds needed, the money should be returned to those who contributed. This would classify the ICO as unsuccessful.

If the funding goal is met, the project will continue to pursue its original goals and contributors will be able to claim their tokens further along. Tokens will either be listed on notable exchanges later on or will be distributed using smart contract technology,This is something you should do more study on before contributing to an ICO.

Advantages and disadvantages

While ICOs have proven to be a massive benefit to project developers, there are some underlying issues and risks that may come into play. In order to give you the best chance of understanding ICOs we will need to cover all the pros and cons that come with ICOs. So let's see what you have to look out for:

Pros

        High potential profits

        Accessible to anyone (unlike IEOs)

        Money returned if unsuccessful (smart contacts)

        Transparency on fund usage (Blockchain)

        High liquidity

Cons

        No intrinsic value

        No legal guarantees

        Potential fraud

Frequently asked questions

Now that we have covered the basics, there are some additional questions the internet has and we thought we would take the time to answer them for you. These are the most frequently asked questions about ICOs, and while we have answered some here is a more TL;DR breakdown:

What does ICO mean?

ICO stands for Initial Coin Offering, a phrase coined by the cryptocurrency industry.

What is the purpose of an ICO?

ICO is a method used to raise funds for up and coming projects, think of it as an early investment phase.

How do I get an ICO?

That depends on the ICO you want to partake in, you will generally need to sign up to the ICO, deposit funds, and wait for the tokens to be distributed either through an exchange or smart contract. This differs depending on the projects' ICO parameters.

Is Bitcoin an ICO?

No, Bitcoin required no funding, tokens were mined and sold without the need for crowdfunding.

How many ICOs are there?

There is no definitive number out there but consensus shows that there have been roughly over 7,000 businesses that have attempted ICOs.

Are ICOs safe?

This is a tricky question and depends greatly on the individual project that is hosting an ICO, whether they are using smart contact technology, and how legitimate the team behind it is. ICOs can be safe, but they also carry risks, it is always best to do your own research before investing.

As there is no universal authority on ICOs there is certainly a lack of regulation in the space so be sure to do thorough research before parting ways with your money.

Closing Thoughts

That is all the essential information you need to grasp in order to better understand what an ICO is. From the textbook definition to its competitors, how it works, and everything in between. ICOs are popular for a reason, they offer a range of benefits to both projects and investors, but you should keep in mind that there is no benefit without risk.

While we can explain what an ICO is, we can not tell you whether to invest in an ICO. It's important to vet the project for yourself and see if it aligns with your interests, and more importantly if it has all the key components for a legitimate project and token.

While the world is increasingly accepting of ICOs from both businesses and retail investors standpoints, there are several alternatives available. We briefly discussed IEOs and IDOs, but more crowdfunding methods have flourished from the origins of ICOs, so be sure to explore those out too. At the end of the day, we hope we helped you better understand what an ICO is.

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.
