Learning the friendly way

The Lightning Network is a second layer solution that enables Bitcoin users to make fast and cheap transactions without compromising on security. The layer two technology allows users to enjoy the benefits of both the Bitcoin and Lightning Network layers simultaneously. Learn more about the Lightning Network solution below.

The Bitcoin trilemma

In order to compete with other payment channels like Visa, the Bitcoin network must be able to process transactions much faster and at a fraction of the cost. However, this scaling cannot come at the expense of decentralization or security.

The "Bitcoin trilemma" is a term used to outline the conflict between these three principles, scaling, security, and decentralization. 

The aim of Bitcoin Cash, Bitcoin SV, and other forks was to increase the block size in order to make Bitcoin transactions faster and more affordable on-chain.

However, these attempts failed to produce an effective method to transact quickly and inexpensively on-chain while still maintaining Satoshi's design. Hence, the Bitcoin Lightning Network.

The lightning network payment channels solution

Is it possible for the Bitcoin network to have it both ways, to keep its original architecture while also functioning as a fast micropayments network? The answer is yes, and thanks to the advent of Lightning Network transactions, Bitcoin can be used for everyday transactions like paying for a cup of coffee.

The Lightning Network is a type of layer two solution that is compatible with the Bitcoin service. This off-chain solution was first conceptualized in 2015 by Joseph Poon and Thaddeus Dryja.

The Lightning Network works by removing the burden of micropayments from the Bitcoin blockchain and instead utilizes multiple payment channels, which are controlled via multi-signature (multi-sig) Lightning Network wallets.

Why the lightning network?

How quickly can the Bitcoin network process transactions? Bitcoin is presently capable of processing between 2 and 7 transactions per second.

Visa, the current payment channel that drives your debit and credit card transactions, handles 150 million transactions each day, that's 24,000 transactions per second.

In order to make Bitcoin a competitive service to Visa, the Lightning Network needs to be implemented. This channel ensures that micropayments are instantly and cost-effectively executed, and is able to process thousands to hundreds of thousands of transactions instantly. 

The core concepts of how the Lightning Network works.

So how does the Lightning Network work? This layer 2 solution works on top of the Bitcoin blockchain, allowing thousands of micropayments to be executed at one time. This lowers the costs and increases the transaction speed of the initial transaction. There are three core components of the Lightning Network: the nodes, channels, and invoices. 

Lightning Network Nodes

This software connects with other nodes in order to form a network that connects to the Lightning Network to facilitate the sending and receiving of Bitcoin. 

Lightning Network Channel

Users of the Lightning Network establish payment channels with one another so that they may conduct transactions off-chain, which can then be settled (closed) on the mainchain (on-chain).

Invoices

Invoices are QR codes that represent requests for Lightning Network payments on the Lightning Network. Invoices include all of the data necessary to complete a payment on the network, such as the payment amount, which blockchain the invoice is associated with, expiration date, payee pubkey, routing hints, and other information.

How to use the lightning network

In order to make use of the Bitcoin Lightning Network, you will need to open a compatible Lightning Network wallet. Once you have downloaded and signed up for the wallet, you will need to send funds. Simply locate the wallet address of the Lightning Network-enabled wallet and send the funds via your normal payment channel. Once the funds appear in your wallet, you can then send transactions via the Lightning Network to other enabled wallets.

Have you heard of the term “altcoin” but not exactly sure what that means? In this article we’re breaking down everything you need to know about altcoins, from the different types of altcoins and how they work, to how you can get your hands on them (buy altcoins). The crypto industry can often feel a little daunting, so we’re here to clear the air and help you establish a strong foundation of insight, knowledge and know how. 

Starting at the beginning, what are altcoins? Altcoins are all cryptocurrencies except for Bitcoin. Not too complicated, is it? Circling back to the early days of the crypto industry when there were only a few cryptocurrencies on the scene, any new coin that was introduced was referred to as an “alternative coin” (labelling it as an alternative cryptocurrency to Bitcoin), which was then shortened to altcoin. So when someone refers to an altcoin, know that they are talking about any cryptocurrency that is not the original (Bitcoin). Altcoins are still decentralized networks, with most of them utilizing blockchain technology.

How Many Altcoins Are There?

At the time of writing, CoinMarketCap reports that there are over 9,400 altcoins in the cryptocurrency industry. This number is increasing by the day, however it’s worth mentioning that these 9,400+ altcoins only make up 50% of the entire cryptocurrency market’s value. Bitcoin is still the most dominant cryptocurrency, with Ethereum the next bigger cryptocurrency. Ethereum is currently responsible for holding roughly 14.5% of the entire market’s value. As Ethereum is also an altcoin, this makes the “altcoin industry” worth $1 trillion. In general terms, one would rather just say the crypto industry.

The Different Types Of Altcoins

With an industry worth over $1 trillion, there is bound to be a wide range of variation. This is just the case with the crypto industry. There are a number of categories that have been created over the years, allowing for various altcoins to provide a new service to the industry. You can also expect to see tons of innovation in the altcoin space, as each new altcoin needs to either improve on the last one, or provide a different use case.

Each cryptocurrency is designed to solve a problem, either faced within the blockchain industry or outside of it, however, many of these have created a niche altcoin market. An example of this is altcoins focused primarily on providing anonymous transactions, these altcoins then fall into the Privacy category. We’ve detailed seven of the main categories below to give you an indication of the vast innovation and use case potential within the space. 

Payment Focused Altcoins

First and foremost, these cryptocurrencies’ primary aim is to provide a medium of exchange within the digital currency realm. Focusing on payment functionality, these digital currencies are akin to Bitcoin and often were created as a “better” version of BTC (through hark forks on the network). Some examples of this include Litecoin (LTC) and Bitcoin Cash (BCH). 

Protocol Focused Altcoins

Protocol focused altcoins are designed to allow developers to work on their blockchain network to create decentralized apps (dapps), smart contracts, and in some cases other cryptocurrencies. They provide space for innovation within the blockchain industry, and empower developers to learn and grow their blockchain understanding. Examples of protocol focused cryptocurrencies include Ethereum (ETH), Tron (TRON) and Neo (NEO). 

Privacy Focused Altcoins

As mentioned above, privacy focused cryptocurrencies provide users the opportunity to send private transactions that are entirely encrypted. While these networks often garner a bad name due to them being used for illicit activities, they are in essence not far from what Satoshi Nakamoto originally intended for Bitcoin. Each network uses slightly different protocols, however they all provide the means to send secure, anonymous transactions. Examples of privacy focused cryptocurrencies include Monero (XMR), Zcash (ZEC) and Dash (DASH).

Stablecoins

You’ve likely heard of stablecoins before. They are the digital currencies that are pegged to a fiat currency. Providing a stable market inside of what has become known as a highly volatile market (cryptocurrencies as a whole), stablecoins offer a hedge against market dips as well as an entry point for users who want to get a feel for the crypto industry. Examples of stablecoins include USD Coin (USDC) and Tether (USDT) which are both pegged to the US dollar, trading at a 1:1 ratio (i.e. 1 USDT will always be worth $1). Stablecoins also include cryptocurrencies pegged to the value of commodities such as gold and oil.

NFTs

NFTs (non fungible tokens) have had their fair share of mainstream media attention recently, especially after one NFT broke records when sold for millions of dollars. NFTs are actually unique crypto assets that cannot be used in the same way that other digital currencies can be. Each NFT holds unique characteristics that represent a one of a kind product, whether it be a piece of digital art, physical art, a house, or even a luxury handbag. These altcoins cannot be recreated, and hold all their transaction history (previous ownership) on a transparent blockchain. They also cannot be “spent” in the same way as other cryptocurrencies in that one an NFT is created, it has that purpose attached to it for life (unlike BTC which can be spent interchangeably).

CBDCs 

CBDCs (central bank digital currencies) are similar to stablecoins but are created and maintained by financial institutions like banks. These currencies’ value is pegged to the local currency, and allow countries to test the efficiency of digital currencies without the volatility. Many countries are in the development phase of CBDCs, however China is leading the pack having recently launched their testing phase. 

Utility tokens

Utility tokens are blockchain tokens that are unique to a particular platform. Many cryptocurrency projects have created utility tokens as a means of crowdfunding prior to their launch, while other projects create utility tokens to be used within the platform for goods and services. Typically, utility tokens have been ERC-20 tokens, and might allow a user access to a new level of a game or to a subscription of some sorts.

How to Get Altcoins

Having gained an understanding of altcoins, individuals eager to explore the thriving altcoin market can effortlessly leverage the capabilities of the Tap app. Tap offers seamless access to an extensive spectrum of cryptocurrencies, including notable names such as Ethereum, Litecoin, XRP, and an assortment of others. It's crucial to bear in mind that not all cryptocurrency wallets exhibit compatibility across the board. For instance, attempting to house an altcoin like XRP within your Bitcoin wallet or stow Tron within your Ethereum wallet would not work due to their incompatibility.

As we explore the world of crypto assets, we take a look at the different types of crypto assets on the market and at the wide range of diversity in the new-age industry. As more people enter the market and start exchanging digital assets, the industry grows and expands to allow new variations.

Below we explore the vast diversity in the industry, from crypto assets used as money to ones that reward users for viewing a website. Each business offers a unique solution, and to navigate this we offer you guidance below.

What Are Crypto Assets?

The terms "crypto asset" and "cryptocurrency" can be used interchangeably. They both refer to a digital asset built using blockchain that can be transferred in a direct peer-to-peer manner. The first crypto asset to launch is Bitcoin, which entered (and created) the scene in 2009. Since then thousands of crypto assets have been created, each one with its own unique use case.

The Different Types Of Crypto Assets

While crypto assets might fall into one or more categories, each has its own set of rules and use cases. 

Payment-Focused

These crypto assets can be used to pay for everyday goods and services or as a store of value (in some cases). These include the likes of Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH), etc.

Stablecoins

Stablecoins are crypto assets that have their value pegged to a fiat currency or commodity. These crypto assets are designed to bypass the volatility synonymous with the crypto market. These include the likes of Tether (USDT) and USD Coin (USDC).

Privacy Coins

Privacy coins are digital assets that hide details of the transaction, such as the origin, destination and amount. These crypto assets offer untraceable monetary transfers. These include the likes of Monero (XMR) and ZCash (ZEC).

CBDCs

Central Bank Digital Currencies (CBDCs) are crypto assets built and maintained by banks. Used as digital currencies alongside the traditional currency, CBDCs are designed to provide a digital version of the local fiat to which the value is pegged. 

Governance Tokens

Common among decentralized finance (DeFi) protocols, governance tokens provide holders with a say in the platform and in future updates. 

Utility Tokens

Utility tokens will typically provide a service to the holder on the platform on which it was created. Commonly created using the ERC-20 token standard, utility tokens might represent a subscription on a platform or a use case specific to that ecosystem. 

Non-Fungible Tokens

Non-fungible tokens, also known as NFTs, are crypto assets that cannot be used interchangeably and instead hold unique and rare properties. Each NFT represents a singular function that cannot be changed.

How Are Crypto Assets Created And Distributed?

Before crypto assets are created the project's intentions are generally circulated through a white paper. In this white paper, the asset's tokenomics will be outlined which will cover how the asset is created and distributed.

Bitcoin, for example, uses a Proof of Work consensus which means that new coins are entered into circulation through miners solving complex mathematical problems. The network was designed to only ever have 21 million coins created, and new coins are slowly entered into the system each time a miner verifies and adds a new block to the blockchain. 

Ethereum on the other hand has no limit to the number of ETH that can be created. The platform is currently moving from a PoW to a Proof of Stake consensus, which alters the way in which transactions are verified, however, new coins still enter circulation through verifying transactions. 

XRP minted all its coins prelaunch and slowly release them into the system through a central authority while Tether creates USDT on demand. For each $1 sent, 1 USDT is created, which can later be removed from circulation should it be sold. 

The Future Of Crypto Assets

From the ICO surge of 2017 to the DeFi explosion of 2020, and more recently, the fervor over NFTs, it's evident that cryptocurrency assets are an enduring presence. Continual innovation and escalating adoption have seamlessly woven crypto assets into the fabric of today's financial landscape.

Though mainstream acceptance is on an upward trajectory, a few challenges still require resolution. On one hand, global regulatory bodies are diligently crafting legal frameworks to accommodate the existence of these crypto assets. On the other, central banks are delving into the feasibility of Central Bank Digital Currencies (CBDCs) coexisting alongside traditional physical currencies. As the world navigates the path forward, one certainty remains: crypto assets are undeniably here to stay, fueling an expanding industry day by day.

Index funds are an increasingly popular form of investment that offers investors a low-cost, passive way to gain exposure to a broad range of assets. With minimal management fees and no need for active trading decisions, index funds can provide investors with higher returns at lower costs than more traditional forms of investing. 

What is an index fund?

An index fund is a type of mutual fund or exchange-traded fund (ETF) composed of a basket of stocks or bonds that tracks a specific stock market index such as the S&P 500 or Dow Jones Industrial Average. These might also be referred to as index mutual funds.

Unlike actively managed funds, which attempt to beat their respective benchmarks through security selection, index funds strive to replicate their underlying market indexes by holding all (or substantially all) of their components in similar proportions. 

This makes index mutual funds more cost-effective than actively managed funds since they incur fewer trading costs and require less research and fewer management fees. On top of that, since they track established indexes, investors can benefit from the diversification within the asset class without having to pick individual stocks themselves. 

Index funds provide an easy way for investors with any level of experience or resources to access some of the market's best-performing assets at a minimal cost. Index mutual funds are also favored for long-term investment strategies such as retirement funds. 

How do index funds work?

Index funds, also commonly referred to as "indexing", follows a passive form of investing (unlike traditional mutual funds that are typically actively managed funds). Instead of fund managers actively trading a variety of stocks, index funds are built by mirroring the securities of a particular index and holding them. 

The key notion is that by mirroring the profile of the index or stock market, the fund will match its overall performance. For example, over the last thirty years, the S&P 500 has grown an average of 10.7% per annum, which its index mutual fund will mimic.

While the most popular index fund tracks the S&P 500, other prominent index mutual funds include:

The Bloomberg U.S. Aggregate Bond Index

Which tracks the bond market.

The MSCI EAFE Index

Which tracks foreign stocks in Europe, Australasia, and the Far East.

The Dow Jones Industrial Average (DJIA)

Which tracks 30 large-cap companies listed on the stock exchange. 

The index fund portfolio holdings will remain as is unless there is a significant change in the market's benchmark index. Benchmarks are used to measure the performance of the market indexes and will influence whether any changes to the composition of the portfolio need to be made. If changes are necessary, managers will rebalance the percentage of securities as necessary.

Passive vs actively managed funds

Both mutual funds and index funds are great investments, however, they differ slightly in how they operate and the returns one can expect. As with any investment endeavor, investing involves risk.

Actively managed funds

An actively managed investment fund offers investors access to an experienced team of financial professionals or simply a fund manager who makes knowledgeable decisions about where and how to allocate the funds across asset classes. This generally enables larger returns than traditional passive investing.

Typically, many mutual funds are actively managed funds, however, it's best not to assume a fund is actively or passively managed simply based on the fund type. There are plenty of funds that break this rule, like actively managed exchange-traded funds.

The advantages of an actively managed fund are that it can earn higher returns and beat the market index. It's important to note that this is not a guarantee so it's best to check the history of the fund you wish to invest in beforehand and the performance of the team managing it.

It's also worth noting that when the mutual fund sells individual stocks it incurs fees and taxes which will affect the fund's performance. Investors are also required to pay a flat fee despite the performance of the actively managed mutual funds, which could result in the mutual fund underperforming the market index.

Passively managed funds

On the other hand, a passively invested fund mimics a market index and does not have a fund manager or team of fund managers making decisions on what and when to invest.

With passive funds, there are fewer decisions to be made and trades to execute, which allows for less effort and lower fees. Automating the bulk of a passively managed index mutual fund makes it much more cost-effective than paying professionals to determine when and what should be bought or sold.

Typically, an index fund will fall into this category as it does not require full-on management. Once the index on which it will mimic is established, the shares are purchased and the index fund continues with little to no input.

Index funds vs mutual funds

Investors looking to build a portfolio have two popular fund options: index funds and mutual funds. Both types of funds are created by offering diversification through a curated range of stocks and bonds and access to professionally managed investments, but there are some key differences between index funds and mutual funds that investors should be aware of before making their choice. 

Index funds typically carry lower fees than mutual funds, but they also come with fewer features and tend to be more passive in nature. 

Actively managed mutual funds on the other hand provide more flexibility when it comes to customization, as well as access to professionally-managed portfolios which may yield higher returns over time. Understanding how both index and mutual funds work will help investors make an informed decision about which type is right for them.

Is it worth investing in index funds?

Financial professionals will typically agree that index funds are a great way for investors to invest passively in the stock market. Not only do they require little input, but they also offer a low-cost option with a strongly diversified portfolio. Index funds also offer a good investment option for long-term investors.

However, it's important to remember that all investments come with risks, and individual financial situations can vary widely. Before making any investment decisions, it is highly recommended to consult a professional financial advisor who can assess your specific circumstances and provide tailored advice. Their expertise will help you make informed choices aligned with your financial goals and risk tolerance.

When learning about cryptocurrencies you're likely to come across the term "smart contracts". First popularised by Ethereum, smart contract functionality is now a regular feature among platforms that allow developers to build decentralized apps (dapps).

In this article, we're breaking down what smart contracts are, how smart contracts work, and where they came from.

What is a smart contract?

A smart contract is a digital agreement that executes based on the terms of the agreement. The terms are predetermined and written into the smart contract's code, ensuring that no edits can be made once the smart contract has been executed. As the smart contract is written using blockchain, the transactions are transparent and irreversible.

Due to the nature of these digital agreements, they can be carried out by two anonymous parties without the need for a third party/ central authority.

Smart contracts generally require payment for their creation, as the execution of the smart contract will require energy from the network. Ethereum smart contracts, for example, require gas fees in order to be created and executed, which are paid directly to the platform. The more complex the smart contract, the higher the gas fees. Other smart contracts will require payment in the digital assets utilized by the platform.

Smart contracts work because they are automated and utilize powerful decentralized technology.

Benefits of smart contracts

First and foremost, the biggest benefit of smart contracts is that they are trustworthy as they cannot be tampered with, nor can a third party intervene. So smart contracts cannot be hacked as they use blockchain technology to encrypt the information.

Smart contracts are cost-effective as they eradicate the middleman and save the users both time and fees that would otherwise come with them. Once certain criteria are met, smart contracts automatically execute, requiring no time delays, paperwork, or room for error. A smart contracts accuracy is determined by the accuracy of the coding used to create the smart contract.

many industries including insurance companies are using smart contracts to streamline and automate their business processes, including fulfilling legal obligations and managing financial transactions. By utilizing if-then statements, the insurance company can create smart contracts that automatically execute the insurance payment to policyholders when certain conditions are met. This can be used to process claims, pay out benefits, and manage other contracts in the same way.

How do smart contracts work?

Smart contracts are digital agreements built using blockchain. Developers looking to create a smart contract will need to utilize a blockchain platform that provides such functionality.

Determine agreement terms

Developers will first need to determine what the agreement terms are as well as the desired outcome. For example, one might create a smart contract that stipulates when 0.5 BTC is received by a certain digital assets wallet the code to a keypad on a property will be sent to the renter.

Determine conditions of agreement

Establish the conditions of the smart contract such as payment authorization or shipment receipt.

Write code

Using a smart contract writing platform, developers will write the code. This will then be sent to another team, such as an internal expert, for security testing.

Smart contracts deployed

Once approved, the code is then deployed on the blockchain platform. The smart contract will then be alerted to any event updates.

Smart contracts executed

Once the terms of the agreement are met and communicated to the blockchain through an oracle (a secure streaming data source), the smart contract will then automatically execute the desired outcome.

One might liken a smart contract to a digital vending machine. The terms of the agreement are understood by both parties involved prior to the transaction. Through an automated process, one party will input the initial criteria (the funds) and the predetermined outcome will be executed automatically (the selected goods will be released).

History of smart contracts

Smart contracts were first conceptualized by American computer scientist, Nick Szabo, the creator of the first digital money "Bit Gold", in 1998. He created them with the intention to digitize transaction methods to replace traditional contract and defined these smart contracts as "computerized transaction protocols that execute terms of a contract."

"These new securities are formed by combining securities (such as bonds) and derivatives (options and futures) in a wide variety of ways. Very complex term structures for payments can now be built into standardized contracts and traded with low transaction costs, due to computerized analysis of these complex term structures."

Szabo's concept remained purely theoretical until the invention of public blockchain technology, which provided the necessary infrastructure for storing and executing smart contracts. In recent years, smart contracts have been used in a variety of industries, including finance, real estate, and supply chain management. While there are still some security concerns with the technology, the use of smart contracts could further increase the efficiency and reliability of transactions.

Conclusion

Smart contracts are digital a contracts between two parties that are automatically executed once certain conditions are met without time delay. Built on the blockchain, smart contracts are immutable, irreversible, and transparent, and require no third parties. Smart contracts are written in varying programming languages dependant on the blockchain network on which they are created. This technology ensures that the smart contracts are implemented correctly.

When exploring the world of blockchain and its endless possibilities, it’s likely that you’ve come across the term “dapp”. But what are dapps? In this piece we explore the concept, decipher their place in the industry, and look at how they feature in the movement toward the next generation of the internet.

What is a dapp?

Decentralized apps, or dapps as they’re more commonly known, are software applications that are built on top of a decentralized platform. 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. Ethereum is currently the biggest host to dapp development, however, there are many other platforms that have shown significant dominance in the space.

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 service 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, DappRadar, in December 2022 there were almost 13,000 dapps in the industry. These are spanned across a wide range of networks, including the likes of Ethereum, EOS, TRON, NEO, and more. 

State of the Dapps also noted in Q2 2023 that the dapps within the DeFi sector now dominated the space, overtaking the previous top sector, gaming. DeFi dominance jumped from 23% to 32% in one quarter while gaming dapps dropped from 45% to 37%. 

Dapps cover a broad range of subjects, catering to industries like energy, exchanges, finance, gambling, games, health, identity, insurance, marketplaces, media, property, security, social, storage and wallets. ‍

Web3: the decentralized net

The transition from Web2 to the decentralized web, known as Web3, marks a revolutionary shift in the internet landscape. This evolution is driven by blockchain technology, paving the way for a more transparent, secure, and user-centric online experience. The movement toward Web3 is closely associated with dapps, which empower users with unprecedented control over their data and information.

Web3 allows individuals to take ownership of their digital presence, allowing for enhanced privacy and real data ownership. As traditional websites give way to dapps that operate on distributed networks, the need for centralized intermediaries falls away enhancing user sovereignty.

In this new era, Web3 unlocks the potential for a more democratized and empowering internet, where users have greater autonomy and control over their online interactions.

The power of dapps

While many dapps may still only be in the experimental phase, there is 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 space at present, the dapp industry is likely to continue growing and become a permanent fixture in many peoples’ lives, whether crypto-inclined or not.
