Learning the friendly way

A recent addition to the top 5 biggest cryptocurrencies based on market cap, Cardano has earned itself an impressive position in the market. In 2021, the Cardano price saw significant price gains as the cryptocurrency went from $0.15 (December 2020) to highs of $3.10 (September 2021). This proved to be a valuable investment for early buyers.

The innovative chain saw increased trade volume on exchanges, not to mention a peaked interest in the service that the platform provides. Designed to be the next generation of Ethereum, let's explore what Cardano is and why has it risen in the ranks so quickly. 

What Is Cardano?

Cardano is the blockchain platform that is taking the industry by storm. Alongside its cryptocurrency, ADA, Cardano provides developers with a platform on which to build decentralized applications (dapps) and smart contracts. Through a more scalable and sustainable model, Cardano seeks to improve on Ethereum's offering and propel the blockchain and crypto industry into a more eco-friendly future. 

Cardano uses a Proof-of-Stake consensus to facilitate the network and is considered to be a third-generation blockchain platform (Bitcoin being the first, Ethereum the second). Unlike other blockchain platforms, Cardano does not have a whitepaper and instead relies on rigorous academic and peer-reviewed research. The platform has numerous ties with universities around the world, contributing to the funding of the development of blockchain research. 

Who Created Cardano?

Cardano was first conceptualized in 2015 and later launched in September 2017 by Ethereum co-founder, Charles Hoskinson. His goal was to build a highly scalable and energy-efficient smart contract platform. After leaving the Ethereum team, Hoskinson grouped together a team of expert engineers and academics and set out to build a layered blockchain platform from scratch. 

Today, the platform is developed by a group of organisations that each focus on different elements of the business. The first is the Cardano Foundation which is responsible for standardizing, protecting and promoting the protocol technology. Input-Output Hong Kong (IOHK) focuses on building technological solutions centred around financial inclusion, while its sister company Emurgo is a global initiative designed to "support developers, startups and enterprises in developing blockchain solutions".

Together these companies assist in the growth and development of Cardano and appear to be doing a great job considering the impressive price gains recently witnessed. While regulatory news and Bitcoin may be behind many altcoin price swings, Cardano has done well to establish its value in the crypto market and build a community that supports its goals.

How Does Cardano Work?

Through a Proof-of-Stake (PoS) mechanism known as Ouroboros, Cardano provides peer to peer transactions, dapp development and the creation of smart contracts. The layered architecture makes this possible, with one layer, known as the Cardano Settlement Layer (CSL) responsible for validating transactions and maintaining the ledger of balances while the Cardano Computing Layer (CCL) is responsible for the execution of all dapp computations via smart contracts. 

The separation of these two layers allows the platform to offer lower fees, less network congestion and faster transactions. When thoroughly tested in 2017, Cardano was able to process 257 transactions per second (TPS), a large jump from Bitcoin's 4.6 TPS and Ethereum's 15 - 20 TPS. 

Through its network of validators (known as a miner on a Proof-of-Work mining network) who each hold a stake in the network, Cardano is able to deploy smart contracts, facilitate the peer to peer exchange of value and provide the building blocks for dapp and token creation. 

What Is ADA?

Before we answer what is ADA, let's first cover where the name came from. ADA is a nod to the person regarded as the "world's first computer programmer", the 19th-century mathematician, Ada Lovelace. Cardano on the other hand was named after the 16th-century Italian polymath Gerolamo Cardano. Each phase in the project's development is named after famed historical characters pertaining to maths, physics and literature.

While ADA can be used as digital cash to conduct payments, the cryptocurrency has a wider range of uses. The native token to the platform's operations, ADA, can be used to facilitate transactions, as a store of value, to participate in staking functionality, and to pay transaction fees on the network. 

ADA will also be used as a governance token in the future, allowing its holders the ability to vote on upgrades and changes on the platform. This is in line with Cardano's intentions to make the network entirely decentralized and community-driven, incorporating an automated treasury system that would oversee and execute all funding required. 

Cardano's Roadmap

Another interesting element to the Cardano network is that all five development phases are consistently worked on at the same time, as opposed to moving on to the next once one is complete.  

Of the five phases that each focus on specific functionalities, three so far have been completed, the most recent occurring in August 2021 when the platform launched smart contract functionality. The next two are focused on scaling, which involves implementing side chains that can facilitate sharding, and then its governance level, which will upgrade the platform into a fully self-sustainable and decentralized platform.

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 is Bitcoin mining?

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.

In a string of new crypto assets available on Tap Global, Chainlink is one of the latest supported cryptocurrencies. The platform is renowned for being one of the biggest oracle platforms in the cryptosphere, making it possible for real-world data to communicate with blockchain applications.

Okay, so it's time to break down exactly what Chainlink is. You might be wondering why you should even care about this network when there are plenty of other decentralized projects out there. It all comes down to the fact that Chainlink aims to fix one obstacle that has prevented smart contracts from becoming more widespread in business and industry. Below we take a deeper look at what Chainlink is and what the platform has to offer. 

What is Chainlink (LINK)? 

Chainlink is a decentralized oracle platform designed to merge the blockchain world with the real world through data integration. The main aim of the platform is to allow smart contracts to capture real-world data, merging the two worlds.

Smart contracts are digital agreements that automatically execute when the agreed-upon conditions are met. Native to the blockchain industry, there is a significant gap between smart contracts capturing blockchain-specific data and external data like the weather, fiat currencies prices, sports scores, etc. 

Bitcoin, for instance, has a very small range of these input capabilities, while Ethereum can handle more due to its smart contract functionality. Chainlink is designed to provide a far greater range of input across the blockchain space through its network of oracles. 

These oracles are data providers that provide a bridge between smart contracts and external data sources. Each oracle is incentivized through a "reputation score" system to provide accurate data and rewarded accordingly with the platform's native token, LINK. 

Who Created Chainlink?

In 2014, Sergey Nazarov and Steve Ellis created a platform called SmartContract which allows smart contracts to come to life by connecting them to external data and widely accepted bank payments. This acted as the prelude to what would become Chainlink. 

The first version of Chainlink first emerged on the scene in mid-2017, founded by SmartContract. Three months later, the Chainlink whitepaper was launched by Navarov and Ellis. This was followed by a successful ICO which raised funds equating to $32 million, selling roughly 35% of the max supply of 1 billion LINK, funding the further development of the platform.

How does Chainlink works?

Alright, so now let's dig down into the nitty-gritty of how Chainlink works. Chainlink allows smart contracts to access external data. To do this, it provides an off-chain infrastructure that links smart contracts to all kinds of different data providers. This makes it much easier for smart contracts to get the information they need. The smart contract can then use this data in whatever way it needs to.

The first thing to understand is that smart contracts need external data in order to do their jobs. This makes sense, right? Your standard contract clearly specifies what happens when certain conditions are met. So what determines whether (and when) those conditions occur? Usually, it's some external force that a smart contract simply doesn't know about.

That means a blockchain-based smart contract can't fulfil its purpose without a way to get information from outside of the blockchain. So what do you do? You could have every individual app developer write their own oracles for each and every smart contract... or you can use a decentralized oracle network.

But what is the difference between centralized and decentralized oracles? Chainlink is great because it can be used to provide an 'outside view' to smart contracts... chainlink allows blockchain applications to securely access off-chain resources like traditional APIs, bank payments, and any other resource that's not currently on the blockchain.

Chainlink provides the security that developers need to run smart contracts without worrying about whether their favourite API is having problems. Chainlink also makes it possible for new data sources to be added to any smart contract which needs them.

Chainlink has three main processes in which it facilitates the communication of off-chain data with on-chain smart contracts. This is done through oracle selection, data reporting and result aggregation, as outlined below.

Oracle Selection

In this step, network users create a service-level agreement (SLA) outlining a set of desired data requirements. The platform then connects that SLA with relevant oracles providing that data. Parameters are then set and the user submits the SLA and deposits the required amount of LINK into what is called an Order-Matching contract, which is matched to the best bidding oracles. 

Data Reporting

Oracles then acquire the necessary real-world data outlined in the SLA from external sources, process the information and send it back to the smart contracts operating on the Chainlink network.

Result Aggregation

The results obtained by the data oracles are then tallied in an Aggregation contract, which assesses the validity of the data. It then allocates a score of the sum of all the data received to the user. This "track record" is used to verify an oracle's integrity, keeping a log of its completed requests, amount of LINK staked and average response time. 

Chainlink is also able to connect with oracles outside of its own blockchain network which is able to collect real-world data requested by the contracts. This process is managed by the Chainlink Core and Chainlink Adapter nodes. 

The network uses a Proof-of-Stake (Pos) consensus, relying on a staking protocol to ensure the network's security. 

How does Chainlink benefit me?

Chainlink is a decentralized oracle network that allows smart contracts to connect to external data sources. These can include APIs, internal systems, or other types of external data feeds. Chainlink's goal is to create a platform where developers aren't restricted from having their smart contracts interact with the outside world in any way they see fit.

You can start using Chainlink right away - no new platforms to learn, APIs to configure or other complex integrations.

chain link will never charge a fee for access to any of our oracle services. Our only source of revenue is the tokens you stake when retrieving outsourced data from your peers on the network.

What is LINK?

LINK is the native token to the Chainlink network and facilitates the communication of data. Considered to be an essential tool in merging blockchain technology with real-world applications, the token has gained wide popularity in the blockchain industry. Users use LINK to pay the nodes for their retrieving, verifying and sending of data. These prices are established by the node operator and based on the current market and demand for that data.

The node operators stake LINK in the Chainlink network to prove their commitment and good intentions. Nodes with bigger stakes take priority over nodes with smaller ones when matching them with SLAs.

LINK is an ERC20 token that powers the ChainLink Network. The LINK token serves three primary purposes:

1. A method to pay ChainLink Node operators for the retrieval of data from off-chain data feeds, like web APIs and other inputs
2. Incentivize the development of oracles that provide data to smart contracts.
3. A method of staking by clients who want access to our oracle network. 

The primary purpose of the LINK token is to secure the network by staking them. The user must stake a certain amount of LINK tokens to run a ChainLink node, which then acts as an oracle. In return, the user is paid for providing this service.

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 trading, cryptocurrencies present a measure of diversification. Considering your risk tolerance and asset allocation, cryptocurrencies could be a part of your 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 for short to long term period.

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.

One of the largest and oldest dapps in the DeFi (decentralized finance) space, Compound Finance has built a reliable reputation among traders looking for lending and borrowing services. Compound operates using its native ERC-20 COMP tokens which provide community governance as well as other services.

What is the Compound protocol (COMP)?

Built on the Ethereum blockchain, the Compound protocol provides liquid money markets offering services such as lending and borrowing. Supporting a number of crypto assets, the Compound protocol allows users to deposit crypto into lending pools providing capital for borrowers on the network and allowing them to earn interest in return.

After depositing funds into the lending pool, lenders are issued "cTokens" (cETH, cDAI, cBAT) which represent the deposit made. These tokens can then be traded or transferred within the platform, or redeemed for the original cryptocurrency deposited. This process is conducted by smart contracts and operates entirely automatically with interest rates algorithmically assigned based on the activity in its liquidity pools. 

The Compound protocol also uses the ERC-20 native COMP token which is distributed to traders that utilize the Compound market, i.e. borrowing, withdrawing or repaying the asset. COMP tokens are distributed each time an Ethereum block is mined proportional to the interest collected from each asset. The COMP cryptocurrency grants COMP token holders governance and voting rights.

Following notable investments from the likes of consulting firm Bain Capital Ventures, Andreessen Horowitz, and Polychain, the platform has grown and established a strong reputation within the decentralized finance space and the greater crypto world.

The history of Compound and who created it

Compound was founded in 2017 by Robert Leshner and Geoffrey Hayes, who both previously held high-profile jobs at PostMates, an online food delivery service. Leshner holds the CEO position while Hayes remains the CTO at Compound Labs, Inc, the software development firm behind the Compound protocol. Compound Labs is an open-source software development firm creating cutting-edge tools, products, and services for the innovative DeFi ecosystem.

In 2018, the platform raised $8.2 million from notable venture capital firms Bain Capital Ventures and Andreessen Horowitz. A year later, Compound raised an additional $25 million from many of the same investors along with new ones including Paradigm Capital.

How does Compound work?

The Compound protocol leverages the power of Ethereum smart contracts and cryptocurrency incentives to benefit lenders and borrowers. Lend and borrow services make up the two main use cases for the platform, as outlined below.

Interest rates on Compound are dynamically managed based on the supply and demand of particular crypto assets within the coin pools. The higher the liquidity, the lower the interest rate. Prices are determined by using the Open Price Feed based on Chainlink's oracles which collect the data from numerous exchanges.

In order to use the Compound DeFi protocol to engage in lending or borrowing services, you will need to connect one of the supported crypto wallets. Currently, the app supports MetaMask, Ledger, WalletConnect, and Tally Ho. The interface has been designed to be user-friendly and easy to navigate, perfect for traders new to the space as well as seasoned DeFi participants.

Lending/supplying

The process of lending on the Compound platform is called supplying. Lenders are able to earn interest on their cryptocurrency by depositing cryptocurrencies into the Compound platform. Borrowers are also required to deposit digital assets into the protocol, which can earn interest but cannot be withdrawn for the duration of the borrowing period.

The platform currently supports roughly 20 crypto assets, from Basic Attention Token (BAT) to Wrapped Bitcoin (WBTC), with Ethereum (ETH) and a number of stablecoins (DAI, USDC, and USDT) being the most actively used.

Once users lend assets to the platform, they are issued with ERC-20-based cTokens corresponding to the cryptocurrency deposited (i.e. cETH, cDAI, etc.). These tokens confirm the liquidity providers' deposits and offer a number of other incentives.

Borrowing

After depositing a particular cryptocurrency into the decentralized finance protocol, users are assigned a "borrowing capacity". This is a limit set in USD based on the rate of the crypto asset which is determined by the Open Price Feed. When depositing multiple cryptocurrencies, the borrowing capacity will factor this in.

Users can also borrow cryptocurrencies supported by the protocol based on a coin's collateral ratio. For instance, if DAI has a collateral ratio of 70%, users can borrow DAI up to 70% of the total amount deposited. Typically, collateral ratios are between 60% and 85%.

Similar to the lending process, when borrowing cryptocurrency borrowers are issued cTokens. So when borrowing DAI for instance, borrowers will be issued cDAI tokens, with the interest payable based on these tokens as well.

Withdrawing

After paying back the borrowed debt, users can redeem their deposited funds. Without having to deal with other traders, the protocol seamlessly utilizes a dynamically maintained set of liquidity pools. The platform also does not charge any withdrawal penalties or hold users to minimum investment times.

When users redeem their funds, the cTokens issued are added to the accumulated interest and converted back to the originally deposited cryptocurrency. These funds can then be withdrawn into the connected wallet.

Account Health

The Compound platform uses a system called "account health" to establish whether accounts are in risk of liquidation. This system measures the sum of the deposited funds against the total amount borrowed. If a user's account health falls dangerously low, the account could be liquidated, and some of the collateral forfeited.

This process is managed in a decentralized way where platform users act as liquidators and monitor for risky accounts. Should they liquidate an account they earn a portion of the liquidated funds.

What is the COMP token?

The COMP token is the Compound platform's native token which mainly serves as a governance token, with a built-in incentive for users holding the token. Holders of COMP tokens are able to vote on all important decisions pertaining to the protocol, including interest rates. Much like the cTokens, COMP tokens are based on Ethereum’s ERC-20 token standard. 

Compound tokens have a total supply of 10,000,000 tokens, of which over 70% of Compound coins are in circulation (at the time of writing).

How can I buy COMP tokens?

With Tap's mobile app, users can easily acquire COMP tokens and store them in the integrated wallet with confidence, either to hold long-term, sell, trade or use on other DeFi platforms. Tap provide an effortless way of trading digital assets, but also a safe space to keep your cryptocurrencies stored.

In order to access the mobile app users will need to download the app and create an account. After a quick verification process, users have access to a wide range of cryptocurrencies. Whether you're looking to buy Compound or sell Compound coins, Tap provides a seamless solution to your crypto needs.

One of the first stablecoins to come into existence, Dai was launched in 2017 and is maintained and regulated by MakerDAO. Using a series of smart contracts, Dai maintains a value of $1, or very close to it. Due to the coin’s soft peg to the US dollar, the Dai stablecoin not only provides a stable long-term store of value but also a strong medium of exchange. 

Let’s explore what Dai is and how it contributes to the crypto ecosystem. 

What Are Dai tokens?

Dai is an ERC-20-based stablecoin pegged to the US dollar. While more stablecoins hold the fiat currency to which they are pegged in reserves, the Dai stablecoin instead uses several cryptocurrencies to ensure it holds its peg. 

Supported cryptocurrencies include Ethereum (ETH), (BAT), USD Coin (USDC), Wrapped Bitcoin (wBTC), Compound (COMP), and many more. With a wide range of collateralized cryptocurrencies, user risk is decreased and Dai's price stability is increased.

Dai is issued and operated by the Maker Protocol and the MakerDAO (decentralized autonomous organization). Designed to provide a means of lending and borrowing crypto assets, the Dai stablecoin was at the forefront of the DeFi revolution. 

Holders of Dai can also earn interest. The platform also has another coin, MKR, which allows holders to set the Dai Savings Rate (DSR) and act as guarantors for Dai. This ensures that MKR tokens can be liquidated if the system fails. This structure motivates guarantors to ensure that the Dai system and its collateralized coins operate properly.

How do you generate Dai?

Users can generate Dai by paying collateral assets. Dai is created when users deposit ETH or any supported cryptocurrency as collateral. The equivalent amount of Dai is then issued and the user will receive Dai tokens.

If the Dai holders want the collateral assets back, the borrowed Dai can be paid back (plus a stability fee) and the collateral assets will be released. This Dai is then removed from circulation.

History of the Dai Stablecoin

The MakerDAO was first launched in 2015 by Rune Christensen and is the longest-running protocol on the Ethereum blockchain to date. It holds more than 2.3 million ETH in its protocol, approximately 2% of Ethereum’s total supply.

When first created, only Ether could be used as collateral, however, in 2019 more cryptocurrencies were added to this list. The Dai price has always been soft pegged to the US dollar.

How Does DAI Work?

The Dai cryptocurrency is an ERC-20 token that can be bought on both centralized and decentralized exchanges (DEXs). Users can also generate and borrow Dai by using MakerDAO's Oasis Borrow dashboard to establish a Maker collateral vault and put Ethereum-based assets in as collateral.

In its original use, the Maker protocol stored collateral in smart contracts known as maker collateral vaults. These smart contracts held collateral in escrow until the borrowed Dai was repaid, also known as collateralized debt positions (CDPs). The value of the security you send always exceeds the amount of DAI you receive otherwise the collateral will be liquidated. 

The Dai platform is one of the most integrated digital assets in the blockchain industry and can be utilized across decentralized finance (DeFi) applications and blockchain-based games, among other places.

The Advantages of DAI

No Minimum Amount Required

There is no minimum account balance required to use DAI, as there is with most other types of money. A lot of people around the world do not have the minimal amount of assets needed in order to qualify for a bank account, but there is no minimum balance requirement for utilizing DAI.

Price Stability

DAI can serve as a safe alternative store of money and access to financial inclusion for people who live in places where the economy is unstable.

Decentralized Financial Inclusion (smart contracts)

As DAI is a transparent and permissionless system, it allows users to have greater freedom over their money. Zimbabwe and Myanmar, for example, have been recognized as countries where people are limited in their ability to access fiat currency due to daily or monthly withdrawal restrictions on bank accounts imposed by the government.

Passive Income

Users can use DAI tokens to earn money through lockup and interest generation through the DAI Savings Rate system. Because DAI is based on the Ethereum blockchain, it doesn't have its own staking mechanism.

Owners of DAI tokens, on the other hand, may profit by putting DAI into a MakerDAO smart contract. This unique smart contract system protects the user's money and allows for immediate withdrawal.

Quick And Cost-Effective Transactions

In many cases, international wire transfer fees can be extremely high, and the time it takes to complete a transaction might be inconvenient. Global transactions between two users' wallets are made more transparent and efficient due to DAI's low transfer fees and quick processing times.

Operates 24/7

Traditional financial institutions operate only during "business" hours. As a result, transactions through such organizations may be delayed for days and will only finalize after banking institutions are open and transfers have been completed. Transactions can now be completed at any time of the year and on any day of the week using DAI and the Ethereum blockchain.

Continuously Vetted

The MakerDAO system has been found to conduct thorough checks and studies in order to guarantee the platform's security. Developers formally validate all smart contracts and core protocol elements that make up the system's internal architecture through mathematical analysis.
