Learning the friendly way

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

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

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

What is a soft fork?

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

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

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

The SegWit fork

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

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

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

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

The Byzantium and Constantinople soft forks

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

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

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

What is a hard fork?

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

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

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

The Bitcoin Cash fork

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

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

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

The Ethereum Classic fork

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

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

Market effects and price volatility

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

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

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

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

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

What to do when a fork is announced

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

 In conclusion

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

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

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

The Sandbox is a pioneer in the movement to incorporate blockchain technology into the gaming sector. Created in 2011, The Sandbox is an play-to-earn game that allows users to be both creators and players, with the ability to monetize their in-game assets and earn SAND tokens.

Powered by the SAND token, the Sandbox’s native token serves as the foundation for all transactions and interactions. SAND tokens can be obtained by playing games, selling digital assets on the Sandbox Marketplace, participating in competitions, or buying it through a reliable exchange. 

What is the Sandbox platform?

The Sandbox is an Ethereum-based play-to-earn gaming ecosystem and metaverse that allows players to create, share, and monetize in-world assets and gaming experiences. The platform combines the powers of decentralized autonomous organizations (DAO), DeFi and non-fungible tokens (NFTs).

The Sandbox metaverse offers players a space to interact with one another and the games they have created.

The Sandbox is made up of three main components: 

1. VoxEdit, which allows users to create and animate 3D objects in the metaverse (i.e. animals, people, tools, etc). These are known as ASSETS and utilize the ERC-1155 token standard which allows both fungible and non-fungible (NFTs) to be minted at the same time. 
2. The Sandbox Game Maker, where users can create 3D games for free.
3. The Sandbox Marketplace, where users can sell their ASSETS for SAND tokens. 

Who created The Sandbox?

Initially developed as a mobile gaming platform by Pixowl in 2011, The Sandbox was intended to be a competitor to Minecraft. It quickly grew very popular and soon had more than 40 million downloads worldwide. However, in 2018, the co-founders Arthur Madrid and Sebastien Borget decided to explore the potential of creating a 3D metaverse on the blockchain.

The new and improved platform allows users to truly own their creations, in the form of NFTs, and earn rewards while participating in the ecosystem. The Sandbox team introduced the new Sandbox project in 2020 and it became one of the fastest-growing games in the cryptocurrency world, alongside Axie Infinity and Decentraland. 

The following year the platform raised $93 million and attracted over 50 reputable partnerships, including CryptoKitties, Snoop Dogg and The Walking Dead. 

How does The Sandbox work?

The Sandbox is a dynamic virtual world filled with user-generated content. Players can create and develop their own NFTs, including avatars, virtual goods, and even games, using the platform's VoxEdit and Game Maker. They can also interact with other players as well as monetize these NFTs by selling them on the Sandbox Marketplace, fueled by the SAND token.

The Sandbox's VoxEdit

VoxEdit offers artists and players user-friendly software to create, rig, and animate NFTs. The NFTs are in voxel format, square 3D pixels that look like lego blocks, which can quickly be edited to create different shapes. Users can design and create everything from animals and game tools to avatar-oriented weapons and clothing to any goods that you can use in The Sandbox. 

All these virtual goods can then be exported and traded as NFTs on the Sandbox Marketplace for SAND token.

The Sandbox's Game Maker

The Game Maker is designed to allow users to test their 3D game creations within the metaverse. With no prior coding experience needed, the program allows users to design and organize various objects and elements in a space called LAND (including the VoxEdit NFTs).

The Game Maker allows users to curate quests, place buildings, and characters, edit terrains, etc. Users can then share their designs with the greater community or sell them on the Sandbox Marketplace.

The Sandbox Marketplace

The Sandbox ecosystem has its very own NFT marketplace was launched in April 2021 and creates a space where users can trade ASSETS (in-game assets) with the native token, the SAND token.

The ASSETS (NFTs) can be anything from wearables to buildings to entities, and can then be used within the platform in the Sandbox game and incorporated into LAND to create unique games using the Game Maker. The Sandbox's marketplace is accessible to all users on the platform.

What are SAND tokens?

Sandbox, referred to as SAND, is an ERC-20 token with a supply of 3 billion. The token functions as a utility token, governance token, and can be used for staking.

SAND as a utility token facilitates all interactions and transactions within the Sandbox ecosystem. In order to take part in the activities available on the platform, from playing the games to buying LAND, trading ASSETS or customizing avatars, users will need to own SAND. The LAND tokens are ERC-721 tokens while ASSETS are user-generated NFTs.

The native token also functions as a governance token within the Sandbox ecosystem, allowing SAND token holders to vote on changes made on the platform through the Sandbox DAO (Decentralized Autonomous Organization) structure. 

Lastly, the token can be staked on the platform, allowing holders to earn rewards and a share in the revenue from all SAND transactions. Staking offers the bonus advantage of allowing users to increase their chances of finding valuable game resources designed to boost ASSETS' rarity, known as GEMs and CATALYSTs. These are valuable when looking to create assets and play games.

There are two ways to acquire SAND: either through playing games and contests in The Sandbox, or by purchasing it on a cryptocurrency platform like Tap.

How can I buy the SAND token?

For those looking to incorporate The Sandbox into their crypto portfolios, or simply enter the metaverse gaming sector, we have great news. The Tap app has recently added SAND to the list of supported currencies, allowing anyone with a Tap account to easily and conveniently access The Sandbox market. 

Users can buy SAND by using balances in either their crypto or fiat wallets or with your debit card, you can also buy the cryptocurrency with traditional payment options like bank transfers. Through the integrated wallets on the platform, users can also store and manage their SAND holdings easily and conveniently. 

Aave is one of the leading decentralized finance (DeFi) protocols on the market, allowing users to easily borrow and lend over 20 different crypto assets. Leveraging the age-old financial practice of lending and borrowing, the platform empowers users to manage their assets in a decentralized manner.

The Aave token also allows users to vote on the platform’s direction and future Aave protocol developments. Aave token holders are granted voting rights based on their holdings.

What is Aave?

Created in response to the rising demand for decentralized money markets, Aave has successfully and firmly positioned itself in the top 10 biggest DeFi markets. Based on the Ethereum blockchain, the protocol allows users to lend and borrow a wide range of cryptocurrencies, from altcoins to stablecoins.

Native to the platform, the AAVE token acts as both a utility token, providing discounts for fees, and a governance token.

By placing digital assets into specific liquidity pools within the Aave protocol, lenders earn interest. Those who need money can use crypto as collateral to take out a flash loan from these same pools.

The decentralized lending protocol was launched in November 2018 under the name ETHLend (with LEND tokens) but later underwent a rebranding after losing traction in the 2018 crypto bear market. After revamping the concept of decentralized crypto lending, the Aave team relaunched the protocol under the name Aave. Aave means ghost in Finnish.

Who created Aave?

Aave was created by Stani Kulechov and a team of developers. Stani Kulechov was disappointed with the lack of lending applications available on Ethereum, so he and a team of developers took it upon themselves to create a space to lend and borrow cryptocurrencies. This project occurred before decentralized finance was even an idea, and launched following an ICO in November 2017.

Kulechov is a self-taught programmer who went to law school after high school and began programming in his teenage years. He is also an early blockchain adopter. The CEO announced that he intended to rebrand ETHLend as Aave in order to provide additional services beyond just ETH lending, incorporating the greater crypto assets market.

How does Aave work for Aave users?

The Aave protocol uses an algorithm that automatically enables loans from the platform's liquidity pools, instead of individually matching each lender to a borrower. On the Aave network, lenders can deposit their cryptocurrency into liquidity pools and in turn earn interest based on the amount deposited.

These interest rates are then paid to the lenders depending on the number of assets being used in the pool. For instance, if all the assets are being utilized, the interest rates are higher as this will provide greater incentive to lenders and more deposit options for Aave borrowers. If utilization is low, the interest rates are lower, attracting more borrowers. Borrowers and lenders are mutually dependent.

Aave loans require users to make a deposit in the form of collateral that is higher in value than the amount they are borrowing. If borrowed assets are not returned within the given timeframe, lenders will take possession of the collateral.

Aave employs a liquidation procedure in the event that the collateral value falls below the collateralization rate established and determined by the Aave protocol. Flash loans are also available, allowing borrowers to borrow money without putting up any assets as long as they pay for the interest fee known as one-block.

What are AAVE tokens?

AAVE is an ERC-20 token that acts as a backstop for the Aave protocol, protecting the system from having a shortage of capital. Known as the "Safety Module", AAVE is sold for assets to cover the deficit if there isn't enough cash in the DeFi protocol to cover lenders' money. Only AAVE deposited in the module will be liquidated. To encourage deposits, a regular yield is paid out in AAVE.

The second major application for Aave is protocol governance. Holders of the cryptocurrency can discuss and vote on Aave Improvement Proposals, which may be implemented if accepted by a specified number of AAVE token holders. This covers altering the money market parameters as well as managing funds in the ecosystem reserve, similar to other governance cryptocurrencies. Each AAVE equals one voting right for Aave holders.

The Aave system uses fees paid on the platform to buy back AAVE tokens and remove them from circulation. Approximately 80% of the fees paid are used for this burn purpose, while 20% are used to incentivize lenders. Aave has a limited supply of 16 million units.

How can I buy the AAVE token?

For those looking to enter the world of DeFi and incorporate Aave into their crypto portfolios, things just got a lot easier. The Tap app has recently added AAVE to the list of supported currencies, allowing anyone with a Tap account to quickly and conveniently buy Aave.

Users can buy / sell AAVE by using balances in either their crypto or fiat wallets or can buy the cryptocurrency with traditional payment options like bank transfers. Through the integrated wallets on the platform, users can also store and manage their AAVE holdings easily and conveniently.

Welcome to the exciting world of NFTs. Non-Fungible Tokens (NFTs) are unique digital assets that have taken the internet by storm. Unlike cryptocurrencies, NFTs represent one-of-a-kind items, from NFT digital art to virtual real estate, making ownership and authenticity easily verifiable thanks to blockchain technology.

Playing a big role in the Web3 movement, the NFT ecosystem is proving its potential when it comes to revolutionizing how we value and trade digital creations. Below we explore the concept, explain how to navigate NFT marketplaces and take a look at the advantages and disadvantages that the NFT market is faced with.

What are NFTs?

Non-Fungible Tokens (NFTs) are unique digital assets built on blockchain technology that have transformed the way we perceive ownership and value in the digital world. Before we get into it, “non-fungible” means that something is unique and cannot be exchanged on a one-to-one basis with any other item, as it possesses distinct attributes or characteristics that set it apart from others. 

Unlike cryptocurrencies such as Bitcoin or Ethereum, which are interchangeable and hold equal value, NFTs are indivisible and represent distinct items, each with its own verifiable identity and scarcity. 

This uniqueness is what makes NFTs special and highly sought after in various industries. From digital art pieces to real estate, NFTs have opened up a realm of possibilities, with some fetching jaw-dropping prices at auctions and marketplaces. 

The most expensive piece of NFT art ever sold was in December 2021, when digital artist Pak's NFT creation "Merge" sold for an astonishing US$91.8 million.

NFTs have empowered creators, artists, and even gamers, as these assets grant exclusive ownership and authenticity of their work or collectibles, sparking a revolution in the way we trade and appreciate digital creations.

How do NFTs work?

NFTs are essentially a digital file created using a blockchain network, meaning that once minted its history of ownership will be permanently stored on that specific blockchain (i.e. Ethereum). 

Blockchain technology forms the backbone of NFTs, operating as a decentralized, tamper-resistant ledger that records transactions across a vast network of computers. It enables transparency and immutability, ensuring each NFT's ownership history and authenticity can be traced and verified by anyone at any time.

Smart contracts, self-executing digital agreements stored on the blockchain, play a pivotal role in NFTs by automating the creation, ownership, and transfer of these unique tokens. These smart contracts encode the rules and conditions governing NFT transactions, enabling seamless interactions and ensuring that creators receive royalties each time their NFT is resold.

NFTs adhere to specific standards, like ERC-721 and ERC-1155, which dictate their structure and functionality on the Ethereum blockchain. ERC-721, the original NFT standard, ensures the uniqueness and indivisibility of tokens, while ERC-1155 allows for the creation of both fungible and non-fungible assets, enabling efficient batch transfers and reducing gas costs.

These standards have paved the way for the vibrant NFT marketplace, supporting various creative and commercial use cases within the digital realm. From digital artists being able to more seamlessly sell their digital artwork to empowering users through trading NFTs, the NFT space is a growing and impressive ecosystem.

How to buy an NFT and navigate NFT marketplaces

Buying and owning NFTs is an exciting journey into the world of digital ownership. To begin, you will need to set up a digital wallet, a secure digital space that stores and manages NFTs. These wallets are available in various forms, from web-based to hardware options, and must support the network on which your NFT was created. Metamask is a common option.

Next, you’ll want to familiarise yourself with several NFT marketplaces. You'll want to find one that offers the NFT projects or NFT collections that you're after, although it is equally important to prioritse security and ease of use when selecting from the range NFT marketplaces. OpenSea and Rarible are two of the largest NFT marketplaces to explore digital artwork and browse NFT collections.

Once you’ve chosen the digital collectibles you wish to purchase, follow the instructions specific to that platform and enter the digital wallet address to where you want the Non-Fungilbe Tokens to be sent. Once the transaction is complete, the NFT will be sent to your wallet and the blockchain will note and verify ownership of that digital asset. 

Should you wish to sell NFTs, you will need to create the digital asset or NFT collections and follow the instructions specific to the marketplace you wish to sell them on.

Digital assets use cases across various industries

NFTs have unlocked a large number of innovative use cases across diverse industries. From real estate to art to gaming, these assets are changing the way data ownership is both viewed and managed. 

In the realm of art and collectibles, artists can tokenize their work into NFT art, proving authenticity and enabling direct sales to collectors, cultivating a new era of digital art ownership. 

NFTs within the gaming and virtual reality platforms allow players to own rare in-game items or virtual land, enhancing the gaming experience and creating vibrant virtual economies. 

While in the music and entertainment industry, these digital assets empower musicians to tokenize albums or concert tickets, transforming fan engagement and royalty distribution. 

Even real estate has seen a shift as NFTs streamline property ownership, fractionalizing investments, and simplifying title transfers. As NFT adoption continues, expect many more industries to embrace this transformative technology.

The pros and cons of NFTs

NFTs bring a host of advantages that are reshaping the digital landscape, however, they are not without their challenges and risks. We explore both sides of the coin below. 

Advantages of NFTs

Firstly, they offer indisputable ownership and authenticity verification, as each NFT is stored on the blockchain, providing a transparent and immutable record of its origin and ownership history. 

This instills trust in both collectors and investors, elevating the value of digital assets to new heights. Secondly, NFTs open up new horizons for artists and creators, granting them unprecedented opportunities to monetize their work directly, without intermediaries, and earn royalties from subsequent resales. This empowerment has fostered a flourishing digital art scene and enabled emerging talents to gain recognition globally.

Additionally, NFTs make digital assets more interactive and engaging by letting creators add special features. For example, gamified NFTs enable users to take part in virtual worlds where in-game items have real-world worth, completely changing how we experience games and encouraging more active involvement.

Disadvantages of NFTs

One major concern is their environmental impact, as the blockchain's energy-intensive nature raises questions about sustainability. Market volatility is also a potential risk, with NFT prices subject to speculation and sudden fluctuations, leading to potential financial losses for investors. 

Additionally, the relative novelty of NFTs has attracted scammers and fraudulent schemes, making it essential for buyers and sellers to exercise caution and conduct thorough research before engaging in transactions.

NFTs have also raised copyright and legal concerns. While they provide proof of ownership for digital assets, they may not necessarily address copyright infringement or unauthorized usage of underlying intellectual property. This requires a careful balance between empowering creators and protecting their rights, ensuring the fair and ethical use of NFTs in the digital ecosystem.

Overall, the advantages of NFTs hold immense promise for the digital world, but addressing the associated challenges and risks is essential for responsible and sustainable growth in this transformative domain.

In conclusion

Thanks to blockchain technology, NFTs have revolutionized digital ownership and value, empowering users through the ability to create, buy and sell NFTs. They provide indisputable ownership verification and empower artists and creators to monetize their work directly. The interactive and gamified aspects of NFTs enhance experiences, but challenges include environmental impact, market volatility, and copyright concerns. As NFT adoption continues, understanding both advantages and challenges is crucial for their responsible and promising future.

The financial landscape well and truly changed after Bitcoin was released in 2009. The new digital cash system took the financial power away from banks and government entities and put it back into the hands of the people. While Bitcoin has become a household name over the last decade, the creator still remains a mystery. Let's take a deeper dive into one of the biggest mysteries of the modern world.  

The Bitcoin solution

Before we plunge into the mysteries of the anonymous entity behind this century's greatest invention, let us first highlight the revolutionary product that is Bitcoin. The electronic payment system was first introduced to the world in late 2008 by a certain Satoshi Nakamoto. 

The character seemingly came from the abyss and presented to the world a solution to the global financial crisis that caused widespread disruption. This solution was in the form of a digital currency and used blockchain technology to facilitate, maintain and operate the network. 

Nakamoto did not invent blockchain technology, instead, he improved on several issues like the double-spending problem. The technology was originally created to facilitate file sharing although was hindered by that issue. Today, blockchain technology has a wide range of use cases and is being implemented in industries around the world, far beyond just the crypto and financial fields. 

Bitcoin remains the biggest cryptocurrency to this day, with over 17,500 alternative cryptocurrencies and counting. At the time of writing the industry is worth just over $2.2 trillion, although it reached highs of $2.968 trillion in November 2021. No asset in the history of the world has gone on to achieve such success in such a short space of time. 

What we know about Satoshi Nakamoto

While we know the name Satoshi Nakamoto, it remains to be known who is behind the pseudonym. This person or entity released the Bitcoin whitepaper in October 2008 to a group of cryptographers and shortly afterwards created the BitcoinTalk forum and Bitcoin.org website. 

Two months later, the first block on the Bitcoin network was mined, known as the Genesis block, with the caption "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." It was mined that same day.

Stephan Thomas, a BitcoinTalk Forum member, mapped out when Nakamoto posted on forums to get an indication of what time zone he might live in. The results showed that he was least active during 6h00 to 11h00 GMT, suggesting that should he sleep at night (not a given for developers) that would place him in a time zone somewhere between GMT -5 to GMT -7, somewhere in the Americas.

During 2010, Nakamoto was an active member of the Bitcoin community. He worked on building Bitcoin's protocol and often collaborated and communicated with other developers. Then, towards the end of the year, he strangely handed over the keys and codes to another active developer, Gavin Andresen, and transferred the domains he had created to other members of the community. By the end of the year, he seemed to have cut ties with the project.

Before all but vanishing, the last trace of communication we know of from Satoshi Nakamoto was a message to Mike Hearn, another developer, on 23 April 2011, that read: "I've moved on to other things. It's in good hands with Gavin and everyone." And just as abruptly as Bitcoin had entered the world, Nakamoto left it.

Who could be behind the anonymous entity? 

While many people have been suspected of being Satoshi Nakamoto, there is yet to be enough evidence to convince everyone else. Over the years, many journalists have tried to lift the veil, and again, to no avail. For over a decade, the world has been left wondering who is behind the anonymous name, and why would they not come forward?

The biggest contenders for the mystery person have been Hal Finney, Nick Szabo, and Dave Kleiman, who have all denied this. One man, Craig Wright, has come forward to claim to be Satoshi Nakamoto, however, the industry remains unconvinced (along with a judge in a recent legal battle that played out in a British court).

Hal Finney

Hal Finney is a computer scientist who had previously tried to create a digital cash system. Finney is noted as being one of the earliest people interested in Bitcoin, with the first transaction taking place between Satoshi Nakamoto's wallet and Finney's. 

Finney also lived in the same town as Dorian Satoshi Nakamoto, a Japanese man who was hunted by the media when they assumed they had found the "real" identity. Finney passed away in August 2014. 

Nick Szabo

Nick Szabo is credited with having tried to create a digital cash system prior to Bitcoin's launch, releasing BitGold in 1998. He also coined the name "smart contracts". The cryptographer and computer scientist was listed as the most likely person to be Satoshi Nakamoto following a study done in 2014 by a group of students and researchers at Aston University who conducted a thorough linguistics analysis on all previous communication. 

Dave Kleiman

Dave Kleiman was a computer forensics expert whose name has come up plenty of times, largely thanks to Craig Wright. Kleiman's estate sued Wright over claims that they had invented Bitcoin together and had access to a large, shared amount of BTC. He died broke and in squalor in 2013.

Craig Wright

The Australian computer scientist and businessman has gone to great lengths to claim to be Satoshi Nakamoto, however, has provided little to no evidence. These claims have been unequivocally disregarded by the Bitcoin community. 

The mystery remains unsolved

Perhaps the biggest irony of all, is that the technology is entirely trustless and operates with the work of thousands of nodes who don't know each other. All we know is that whoever it was/they are, they revolutionised the world as we know it and have left us with some sort of extraordinary.

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

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

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

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

What is Ethereum? Explained simply

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

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

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

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

How Ethereum works

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

What are smart contracts?

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

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

What is Ether (ETH)?

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

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

What are gas fees?

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

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

What are token standards?

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

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

The 3 main Ethereum token standards:

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

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

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

The Ethereum ecosystem

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

Decentralised applications (dapps) 

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

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

DeFi (decentralised finance) 

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

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

NFTs (Non-Fungible Tokens) 

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

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

DAOs (Decentralised Autonomous Organisations) 

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

Ethereum 2.0 and The Merge

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

• Environmental impact 

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

• Scalability 

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

• Staking opportunities 

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

Ethereum vs other blockchains

Ethereum vs Bitcoin 

While both use blockchain technology, they serve different purposes:

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

Ethereum killers

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

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

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

Ethereum's advantages 

Despite strong competition, Ethereum maintains significant advantages:

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

Risks and considerations

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

Price volatility 

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

Security concerns 

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

Regulatory uncertainty 

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

Technical challenges 

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

The future of Ethereum

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

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

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

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

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

How to buy Ethereum (ETH)

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

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

Final thoughts: why Ethereum matters

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

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

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