NFTs: A Token of Gratitude

NFT projects are often tarred by the same brush. Since the meteoric rise in 2021, NFTs are usually seen through the materialistic gaze; the imagery created is designed to be used as a profile picture across social media and forums. The push-in PFP images, along with a wealthy community bankrolling new projects certainly shape a world where many are paying for exclusivity, clout, and opportunity. 

For some, the hyper-popular NFT projects such as Bored Ape Yacht Club, Meebits, and CryptoPunks are the equivalent of a verified blue tick. But among the noise of floor prices skyrocketing and celebrity tradings, there are creators and entrepreneurs using NFT technology for the good of the world and our society. These creators are taking NFTs far beyond the visuals.

In a Time of Crisis

We cannot look at this shift of using NFTs for good without examining their use in the current humanitarian crisis happening in Ukraine. As the invasion of Ukraine by Russia rocked the globe, many were left wondering how they could send aid towards those losing their homes, identity, and history. The war, understandably, has created volatility in global financial markets, with fiat (traditional) currencies taking a hit.

One of the first projects launched to aid those in Ukraine came from a collaboration between Nadezhda Tolokonnikova and the digital artist Trippy Labs. Together they minted 10,000 NFTs of the Ukrainian national flag on the Ethereum network. This project, to date, has raised over $6.7 million to support the military of Ukraine. Elsewhere, 500 Ukrainian artists have gathered together to launch the Holy Water NFT project, funds from which will be used to support the people of Ukraine.

There are many projects being launched across the world which aim to bring financial support to those in desperate need. Cryptocurrencies, alongside the NFT sphere, are enabling those in Ukraine to take in donations not set against the turbulent fiat markets. Since tweeting out their crypto wallet addresses, the Ukrainian government, through Vice Prime Minister Mykhailo Fedorov, has received nearly $40 million in crypto donations, along with many NFTs which can be sold on secondary markets to raise further capital.

Supporting Equality

Artist Yam Karkai, principle creator of the World of Women (WoW) NFT project, says this about her work: “The mission of my art was always to showcase women, put them in the spotlight, and bring more diversity into the space.” The World of Women project sought to focus on women within the traditionally male dominant industry. 

Launched in July 2021, WoW released 10,000 uniquely generated NFTs with a floor price of 0.07ETH – around $203 currently. Since then the project has had artwork featured with auction house Christies in London, as well as support from high profile celebrities. This has raised that originally low floor price to around 9ETH – around $26,300 currently. Throughout the campaign, WoW has donated over $250,000 to women’s charities, including She’s The First and Too Young to Wed.

Elsewhere, female creators are releasing highly successful NFT campaigns which aim to heighten awareness of women’s rights in various areas. Boss Beauties champions female empowerment, selling out the entire collection in just one hour after the initial minting. A subsequent campaign was released recently, in partnership with the United Nations for International Women’s Day 2022. The new collection featured inspiring women from throughout history. Included in the NFTs were; Frida Kahlo, Maya Angelou, among others. Proceeds from the charity sale were donated to fund scholarships for women and girls.

While progress is being made within the NFT space to further equality, ‘It’s Nice That’ notes that the art movement is distinctly white, leaving many black and ethnic creators without a voice. Aiming to tackle this issue is illustrator Aurelia Durand, in collaboration with The Black Arts Project. Together, the team has created a 10,000 strong collection celebrating those of African descent and African diaspora. 

The collection will benefit important black causes “from grassroots to the metaverse” and champion equality. In discussion with It’s Nice That, Anthony Gibbs, founder of The Black Arts Project, believes the creative space “isn’t welcoming to black people” and “this is even reflected in the fact that NFTs with white complexions are selling for more than those with darker complexions”.

It’s Our World too

It’s no secret that the planet is rapidly sliding into a climate crisis. And many would argue that NFTs and cryptocurrency are accelerating this issue, despite positive steps in Proof of Stake. Some creators are hoping to tip the scales in the other direction, or at the very least use NFTs to boost awareness of the environmental issues at hand. The priority is leaning towards using NFTs as tokens to represent conservation efforts worldwide.

If you choose to be a Nemus guardian, you’ll own an NFT image that acts as a token representing a portion of the Amazon rainforest. Of course, you don’t own the slice of land itself, but your money does aid and benefit indigenous people living within the rainforest, while also creating a protective border to prevent deforestation. The project’s most expensive option rewards the buyer with “diamond rarity’ artwork, representing 81 hectares of land which locks in approximately 28k tonnes of carbon.

Sticking with the lungs of the Earth, the Woodies project also sold 10,000 NFTs which can be used as PFPs. The project raised 73.824ETH – currently $223,961 – and this money trained 1,600+ farmers and planted over 837,000 across sub-Saharan Africa, which results in over 30,000 metric tonnes of carbon dioxide being sequestered over twenty years.

Utilising blockchain gaming and NFTs are Purple Penguin, a project which aims to “revolutionise climate conservation”. Working with Project Ark, Purple Penguins has created carbon-neutral NFTs by minting them on the Polygon network, which is known for its low fees and low energy approach to blockchain programming. The funds raised from the NFTs and their blockchain gaming platform AntARTica will go directly to charities conserving the climate and wildlife in the southern hemisphere.

In its very early stages is the project Good Cactus Frens which aims to sell NFTs to raise money for Charity Water, an organisation that provides clean drinking water to those in need. While this project has barely left the ground, it’s admirable to see more of these concepts brought to the fore.

What’s the Next Step?

Ultimately, NFTs and blockchain generally, have a trifecta of issues that taint even the noblest of causes with a daub of darkness. Dubbed by many as the “trilemma’ these flaws in the technology will, until solved, frequently hold back the effectiveness of goodwill campaigns and projects. The trilemma breaks down thus: 

Decentralisation – Blockchain technology needs to further distance itself from centralised companies, giving equality to all users.

Security – Each blockchain must have better than ironclad defence to malicious attacks, phishing scams, and hacks.

Scalability – Blockchains need to be able to handle large volumes of transactions at speed and without fault while reducing the costs of fees to the user.

It’s the second and third points that could hamper progress for charitable causes. Without being able to guarantee the security of their patrons, fewer people will be willing to take a chance and invest their money. This lack of security can be seen in two ways; vulnerable blockchains open to hacks and bad actors who could set up a charitable fund only to ‘rug pull’ buyers and disappear with a bounty of cash into the anonymity of blockchain. A way to combat this issue is for groups to doxx themselves and bring down that curtain that hides their identities, which would go some way to setting potential investors at ease.

We can’t forget the issues of scalability, though. Currently, there’s a dilemma occurring and its name is Ethereum. Ethereum is the blockchain daddy right now. Only Bitcoin is close in computing power and market dominance. But Ethereum is both an energy hog and a money sink. Gas fees are still outrageous and the number of nodes needed to compute the algorithm burns through energy.

On the flip side, Ethereum is popular, reasonably secure, and reliable. This makes it an appealing place to launch goodwill projects, despite the inherent flaws described above. A balance will hopefully soon be struck allowing for environmental conservation without the impact of the blockchain counteracting it.

Can Blockchain Better the Planet?

In short, yes it can. Eventually. The unrestricted movement of funds due to cryptocurrency can hugely benefit charitable causes, particularly when avoiding the ups and downs of fiat currency. However, the problems crypto faces, as explained above, are not the only issues. The biggest perhaps, is adoption.

While there are now millions of people who hold a cryptocurrency wallet, many of these users will own several wallets, due to crypto compatibility, while many of them will remain empty. Until governments begin proper legislation discussions and adopt crypto as an alternative to traditional currencies, it’s hard to imagine crypto being welcomed by society as a whole, meaning these NFT projects are ultimately being sold to an incredibly small market.

The world of crypto and, by extension, NFTs is riddled with jargon and instructions many would find obscure. Once this issue has been overcome, the wider public will be more accepting and open to supporting charitable NFT projects, which would also help in breaking down the current climate of non-utility PFP projects.

Why PFPs are the new Blue Check

NFT was the Collins Dictionary word of the year in 2021 and, at the start of 2022, you can’t move for people and companies trying to get in on the action. It’s clear that the thrill of exclusivity and owning something verifiably unique that others don’t have access to has caught people’s imagination. Trust in NFTs is gaining momentum as brands like Adidas start moving into the metaverse space, focusing even more attention on this relatively untapped asset class. In amongst the buzzwords like NFT and metaverse, it’s likely you’ll have come across the term ‘PFP’ (profile picture) through NFT projects like Bored Apes Yacht Club (BAYC), Crypto Punks, and Fancy Bears. And, increasingly, it’s PFPs that are serving as entry tokens to some of the most sought after communities and experiences in both the metaverse and IRL.

A brief history of PFPs…

PFP or ‘avatar’ collectables are responsible for a large part of the uptick in activity and interest around NFTs. Usually, a PFP NFT project is a cluster of avatars (typically about 10,000) where each avatar has a unique assortment of traits such as facial expressions, clothing and accessories. These traits are algorithmically assigned to individual avatars which are automatically generated based on original artwork. Therefore, these projects are referred to as “generative art”.

The OG of PFP projects is CryptoPunks, which has generated over $2 billion USD in trading volume on the secondary market. Just this month, a single Punk sold for 8,000 ETH, worth close to $23.7 million. The remarkable thing about CryptoPunks and other important PFP projects is that their NFTs are often given away for free or for a nominal price at the start of the project. An example of this that has captured the most mainstream attention is BAYC, a generative PFP NFT project that has 10,000 unique Apes. Anyone with a bit of spare change and tech-savvy could have got hold of an Ape for a mere 0.08 ETH + fees when they first dropped in April 2021. Fast forward to today and the cheapest Ape sits at around 13 ETH. Recently, Fancy Bears Metaverse sold out its 8,888 PFP Bears in just 8 minutes, attracting celebrity holders such as Floyd Mayweather and Jay Alvarez.

What makes PFPs the ultimate check mark?

Despite the column inches and social media noise they generate, PFPs are nowhere near mass adoption – yet. But because they have such passionate and vocal communities, they are gaining mainstream traction. Even on the professional social media platform, LinkedIn, NFT PFPs have become a fairly common sight (although they’re often taken down by the platform for not representing a user’s true likeness!). Twitter has recently pursued a very different tack by integrating verification of PFP NFTs, enabling users to not only display them but demonstrate their authenticity to the world. With hundreds of thousands of Twitter users sporting a blue ‘verified’ check mark, it’s safe to say that a legit Bored Ape PFP is now a far more powerful flex, marking you out as part of one of the most coveted communities on the planet.

I still haven’t really explained why leading PFPs have such value. It’s not because they can be exchanged for large amounts of money, although the potential to generate a return certainly doesn’t hurt. But this is a byproduct of their intrinsic value, which is a community of shared values. The metaverse is fast becoming a core of many PFP holders’ social and professional lives. It’s where they make business deals, enjoy concerts or just shoot the breeze with holders who are likely to have similar interests and ambitions. 

PFP project creators can add further value to the community through benefits such as personalised merchandise, exclusive metaverse and IRL parties, giveaways, access to celebrities, and profit share from the projects’ royalties through democratic decentralised organisations called ‘DAOs’. PFPs are check marks without parallel in any other walk of life, making you a lifetime member and an equal shareholder, opening doors and generating FOMO in those on the other side. 

Final thoughts on PFPs

So you bought Tesla stock before it was cool, graduated from Harvard, got a CORE membership and are verified on Twitter. In a world that’s moving rapidly towards Web3 – the decentralised internet – I hate to break it to you, but you’re old news. PFPs represent the ultimate new blue check precisely because they’re disconnected from these entrenched ways of displaying status and privilege. Their intrinsic value comes from communities that have grown from humble origins because of shared passions. They inspire others to want to join, rather than creating exclusivity through deliberate exclusion. And it’s only fair that they enable a little flexing from those who saw their potential first.

How do Blockchain Platforms Differ?

A quick glance at the largest cryptocurrency tokens reveals a host of diverse offerings, each with markedly different approaches when it comes to their underlying use of blockchain. From those that focus on being investment vehicles to others that specialize in hosting distributed applications, how exactly do these blockchains differ in their approach?

Bitcoin

Even the most casual follower of technology will be familiar with Bitcoin, which for many might also be practically synonymous with cryptocurrencies in general. That’s reflected in the fact that other cryptocurrencies are commonly grouped together as “altcoins” versus the monolith that is Bitcoin.

Its popularity stems partly from its first-mover advantage. Its journey to becoming by far the largest cryptocurrency started with its release in 2009. Developed by a mysterious person or group known as Satoshi Nakamoto, the currency is well known for its significant price fluctuations (topping out at around $69,000 in November 2021) as well as its pioneering use of blockchain technology.

While we won’t dive too deep into the specifics of how blockchains work, in the case of Bitcoin the work of joining together the eponymous, unalterable blocks is done via a process known as mining. To ensure that new data is permanently stored on the blockchain, computers on the network compete to solve increasingly complex mathematical problems. The miner who successfully solves the problem is then given Bitcoin as a reward. The chance of winning is directly correlated to the amount of work that can be done on the problem – hence the emergence of gigantic Bitcoin farms in areas where energy prices are low.

Bitcoin’s prominence means many of the negative headlines regarding blockchain technology (such as its outsized impact on the environment) involve the cryptocurrency in some way. It’s also recently been the centre of controversy after the nation of El Salvador adopted it as legal tender – a move the IMF condemned.

Hot and Cold Crypto Wallets

Ethereum

Where Bitcoin is focused on digital currency, Ethereum sets itself apart by virtue of its programmable nature. The open-source platform has become well known for its support of decentralized applications, smart contracts, NFTs (non-fungible tokens), as well as the ubiquitous cryptocurrencies.

That’s all accomplishable thanks to the fact that Ethereum is a so-called “Turing Complete” blockchain. What that means is that it can be coded to perform any task required of it via decentralized applications (dapps). Dapps include things like games and exchanges, all running securely on the blockchain. As a result, they gain all the security and uptime benefits of the technology – with all their code and data hosted, secured and verified by computers on a distributed network.

Then there are smart contracts, programs deployed on the blockchain that automatically execute agreements based on the rules that are coded into them. Thanks to that, they can be used as infallible intermediaries for executing transactions, ensuring that everyone involved is certain of the outcome once the prerequisite conditions are met. Ethereum is also well known for powering NFTs (non-fungible tokens), which use the blockchain to confer proof-of-ownership onto digital items such as digital art, video game items, music and much more besides. The principle is much the same as cryptocurrency, only an NFT points to a unique asset, while any given unit of cryptocurrency is identical.

Like Bitcoin, Ethereum only functions thanks to the energy-intensive process of mining – as they share the consensus mechanism known as “proof-of-work”. However, the platform is currently planning a raft of upgrades to move to another form of validation known as proof-of-stake. The platform is hoping that will solve scalability problems hampering its dapps. Currently, Ethereum can only handle somewhere between 15-45 transactions per second. To ensure that transactions get through such a congested system, exorbitant transaction or gas fees have to be paid by users. With upcoming upgrades the blockchain is targeting 100,000 transactions per second, meaning those associated fees should fall.

Solana

Like Ethereum, Solana is a generalist blockchain, supporting cryptocurrencies, decentralized applications, smart contacts and NFTs. It was founded in 2017 and is operated by the open-source Solana Foundation based in Geneva, Switzerland.

Solana’s blockchain emphasizes throughput – with transactions-per-second around 2500 compared to Ethereum’s 30. It achieves this via a process known as proof-of-history, whereby every transaction is given a cryptographic timestamp. That ensures there is a verifiable sequence of transactions without requiring the work of every node to validate it, meaning less computing power is required and lower gas fees have to be paid.

Unlike Ethereum and Bitcoin, however, it utilizes a proof-of-stake consensus mechanism. That sees users staking cryptocurrency to become validators. They are then randomly chosen to create new blocks as well as check and confirm blocks created by others. The tokens they have staked can be taken away if they approve fraudulent transactions, incentivising them to validate correctly – at which point they receive tokens and the transaction fees within a block.

Terra

Finally, South Korea-based Terra was founded in 2018 by Do Kwon and Daniel Shin. The Terra blockchain specializes in facilitating so-called “stablecoins”. These are cryptocurrencies that track the price of real-world fiat currencies. The blockchain supports two main complementary types of cryptocurrency tokens known as Terra and Luna respectively. The Terra tokens are pegged to the price of real-world currencies (TerraUSD being pegged to the United States Dollar). 

That’s achieved thanks to the Luna token, which serves to stabilize the price of Terra stablecoins. Users must “burn” Luna to mint Terra and vice versa. The system algorithmically incentivises one process over the other to keep the currency stable. While the price of Terra is maintained, as the use of the blockchain grows the price of Luna increases.

In line with all this, the Terra network touts its decentralized finance (DeFi) credentials, a movement to remove third parties from financial transactions. As such it supports decentralized applications including decentralized savings protocol Anchor

Summary

Even in the relatively early days in which we live, the inherent flexibility of blockchain technology has resulted in a broad swathe of use cases. While the blockchains we have discussed are leading the market at present, disruptors with pioneering new approaches to using the technology can be expected to join the pantheon at any time – with services like Chainlink’s oracle platform being just one potential bet.

All You Need to Know About Blockchain

Blockchain. While you may think the term has reached maximum saturation, expect it to become even more inescapable over the next few years as more and more solutions are built on top of it – be they dapps, DAOs or NFTs. Which makes understanding exactly what blockchain technology is on a fundamental level fairly crucial. Speaking of…

What is a Blockchain?

A blockchain is fundamentally a digital ledger that records information and stores it securely, verifying its authenticity through cryptography. Crucially, the work of updating the blockchain is a shared endeavour, carried out by computers across a network. That means a blockchain can be a secure and authentic record while remaining decentralized.

As you may be able to tell from the name, blockchains consist of “blocks” of data, joined together in a chronological chain that tracks precisely where assets are moving to and coming from. Once a block is created, it cannot be removed or altered, meaning that its position in the chain (as well as the date and order of transactions it contains) is permanently recorded. 

The physical hardware running the software of any given blockchain are referred to as nodes. Their responsibilities range from the aforementioned validation of transactions and setting the state of the blockchain to serving as the endpoints that enable users to actually access applications on the network.

Of course, as a decentralized network, users need to be incentivized to maintain the blockchain. That is usually financial, in the form of newly created cryptocurrency or from transaction fees paid by other users. These “gas fees” pay for miners to use their hardware to create the new block necessary.

Blockchain Scalability

Consensus Mechanisms

All of this is only possible thanks to consensus mechanisms that ensure every node agrees. Depending on the specific mechanism (such as proof-of-work or proof-of-stake), a blockchain grows via a process known as mining or validating. 

Proof-of-work mining involves computers on the network competing to solve increasingly complex mathematical problems in order to securely add new blocks onto the blockchain. Winning the race is a game of chance, but your odds are significantly improved the beefier your hardware, meaning mining is an energy-intensive affair. The miner who succeeds in creating the block is given new tokens – as well as the transaction fees contained within the block.

Proof-of-stake validation, meanwhile, sees users depositing cryptocurrency to become validators in a process known as staking. They are then randomly chosen to create new blocks as well as check and confirm blocks created by others. Once a block is validated, the validator then gets tokens and the transaction fees within. The tokens they have staked can be taken away in the event they approve fraudulent transactions.

In both cases, new transactions are verified and recorded without the interference of one central authority. Proof-of-stake is viewed as a greener solution for blockchain construction, with Ethereum being one example of blockchain targeting a move from proof-of-work. It also helps solve another of the problems plaguing the technology: scalability. Ethereum can only handle somewhere between 15-45 transactions per second – with upcoming upgrades the blockchain is targeting 100,000 transactions per second.

Why use Blockchains?

With all that in mind, you might be wondering why you would go to the trouble of doing all that just to produce a ledger – hardly the most groundbreaking of technologies. The key innovation that makes blockchain such an intriguing technology, however, is the fact that it is decentralized. What that breeds is trust. With data stored and synchronized across the network, immutably, users can be assured that everything they need is present and correct – all without the interference of a third party taking its own cut.

This fact enables a number of exciting possibilities, perhaps chief among them smart contracts. Essentially programs stored on the blockchain, their immutable nature means that they are guaranteed to execute whenever the conditions programmed into them are met. That means they can be used to automate agreements, again without relying on a third-party arbiter.

Smart contracts can be used to power everything from games to decentralized finance applications, but one of the most exciting possibilities is their use in oracles. Oracles connect reality to the blockchain by using off-chain data, perhaps from a real-world sensor, to trigger events. A prominent example is Chainlink, which allows users to connect smart contracts to real-world information such as weather data – in turn enabling parametric insurance that reimburses farmers for reduced crop yields caused by drought after a weather sensor detects low levels of rain.

Who are the Big Players?

In terms of name recognition, Bitcoin is certainly the best-known blockchain, thanks to the precipitous rise of its eponymous cryptocurrency. Since launching in 2009, its pioneering approach has seen it become far and away the largest cryptocurrency by market capitalization.

For possibilities on the blockchain other than cryptocurrency, however, Ethereum has proved to be the most popular. Having launched in 2015, it has made its way to being the second-largest by capitalization on the back of its smart contracts, decentralized applications and non-fungible tokens. Open source, the blockchain refers to itself as “programmable”, with a dedicated programming language for writing smart contracts known as Solidity.

Among the also-rans, the largest blockchain to have implemented the previously discussed proof-of-stake consensus mechanism is Cardano. Then there’s Solana, the USP of which is its use of proof-of-history to increase throughput – with transactions-per-second currently hovering around 2500. Proof-of-history sees every transaction given a cryptographic timestamp to produce a verifiable sequence of transactions that doesn’t require every node to agree, resulting in less computing power being required.

Summary

Now you understand what a blockchain is, it’s well worth diving deeper into some of the many possibilities the technology enables. Take a look at some of our other resources to find out more about NFTs, virtual land and blockchain gaming, to name but a few!

The Pros and Cons of Hot and Cold Wallets

In the cryptocurrency world, a wallet is a piece of software or hardware that stores the cryptographic keys necessary to access your assets stored on the blockchain. Those keys consist of a private and public pair. The latter identifies the wallet, allowing it to receive tokens without revealing the identity of the owner. The private key, meanwhile, is what gives you access to the wallet – whether that’s to check balances or perform transactions.

While asking someone the temperature of their wallet in the real world might draw some blank stares when it comes to crypto wallets that’s perfectly appropriate, as they fall into two categories: hot and cold. So just what is the difference between the two and why would you favour one over the other?

Hot Wallets

This category ranges from mobile wallets to desktop programmes and web-based solutions such as accounts with crypto exchanges. Think MetaMask or Coinbase Wallet, to name two popular examples. The key defining feature is that they are connected to the internet, meaning all are vulnerable to online attacks. Levels of security differ hugely within the category, however, with web-based wallets generally being deemed among the least secure as they are vulnerable to security breaches.

That being the case, why use a hot wallet? Ease-of-use. The fact that a hot wallet is always online means there is no impediment to making cryptocurrency trades, purchases and transactions – unlike with a cold wallet, which needs to be plugged in and currency moved out of before a purchase can be made.

It’s good practice to not store too much in a hot wallet, however, owing to the aforementioned security concerns. The analogy that is often deployed is to treat a hot wallet as you would the one you store in your pocket – just enough cash to get by without it being a devastating loss if you lose it. 

Cold Wallets

If a cold wallet is connected to the internet, it stands to reason that a cold wallet is not. Cold wallets include physical cryptocurrency with private keys printed under tamper-proof stickers, or even simply writing down your private and public key pair and storing it on a piece of paper.

When you hear cold wallets being discussed, however, usually what’s being referred to is a hardware wallet. These devices often look like USB sticks only with a screen and buttons – as popular examples from Ledger attest. Such devices store cryptocurrencies internally, meaning a bad actor would need to physically have the cold wallet as well as the PIN code to gain access to them.

Adding and removing currencies is a question of connecting it to a computer. You might think this would be the moment of greatest vulnerability, but all transactions are completed in-device, meaning it is impossible to hack remotely.

So far, so good, but there are downsides. Firstly, you have to stump up the funds, and as a physical object, cold wallets open up the danger of the keys to your cryptocurrency being stolen or even accidentally discarded – we’ve all heard the horror story of the guy who threw away a hard drive containing a fortune in Bitcoin. 

With hardware wallets, that wouldn’t be the end of the world, however. Recovery phrases allow the funds held inside hardware wallets to be restored elsewhere – meaning protecting the recovery phrase is almost more important than the wallet itself.

The Verdict

The exact amount you might be comfortable with storing in a hot wallet depends on the reputation of the exchange you are using. Reputable exchanges will be using a system of cold wallets in the background, keeping their customers’ funds offline, with a certain amount stored online for withdrawals.

It’s worth also considering providing some means of accessing your wallets, hot and cold, to loved ones if you are incapacitated for whatever reason. After all, if you are the only one who knows how to access your cryptocurrency, then those funds could well die with you.

Ultimately, it’s a combination of both hot and cold wallets that is the best approach. The actual balance of hot and cold will be dependent on your approach – and how much you value security versus functionality. For those who want to sit on vast amounts of cryptocurrency, clearly, there is an incentive to maintain cold, hardware wallets, while frequent traders of smaller amounts will favour hot wallets they can quickly move coins in and out of.

Not only that, but it might be a good idea to have multiple examples of each category for different purposes – storing a certain amount with an exchange you frequently use, storing currency you plan to hold for a long time on a hardware wallet and using a mobile or desktop wallet for more speculative purchases. The choice is yours!

Regulating Web3

The regulation of the web as it currently stands is in a state of flux. The big beasts of Web 2.0, the likes of Google, Amazon and Facebook, have repeatedly locked horns with governmental organizations around the world in recent times – usually coming off the worst. The platforms’ poor record on disinformation and misuse of data has led to crackdowns ranging from huge fines being levied in the EU to burgeoning antitrust cases in the United States.

As Web 2.0 gives way to Web3, are we doomed to experience an intensification of the problems that plague the web today, or is this an opportunity to reset the status quo? Just what are the priorities when it comes to safety, privacy and antitrust, and who is leading the way?

Web3 - Metaverse

The Problem with Decentralization

With efforts to regulate disinformation on centralized platforms having proved hard enough, a whole new spanner is thrown in the works when one considers the inherently decentralized nature of Web3. The growth of blockchain and cryptocurrency technology which has made a move away from centralized platforms possible precisely what is fuelling the question of who the task of regulating Web3 should fall too.

On today’s internet, we can be relatively assured that our activity is private(ish), that illegal and unsavoury content will (eventually) be removed and that miscreants can be banned from platforms. But the decentralized nature of the blockchain removes all those safety nets by making all transactions public and unchangeable. By moving wholesale to Web3, not only will existing approaches to safety be rendered unusable, but whole new problematic worlds could emerge – imagine governments or even companies being able to scan blockchain transactions to discriminate against certain users.

There’s another wrinkle associated with Web3 too in the form of the Metaverse – a bevvy of platforms offering virtual land populated by anonymous users who are free to make of their spaces what they will. That decentralized creator economy means that users can enjoy the fruits of their creations, but what sort of behaviour can be expected in these anonymous virtual spaces? Virtual groping is just one unsavoury example – with the mooted solution, in that case, being a deployable “safety bubble” in which no one can touch, talk or interact until it is suspended.

Existing Approaches

Despite decentralization perhaps being the holiest of holies for Web3, workable answers to these issues all seem to fall back on incorporating some sort of centralized regulatory body. But there are attempts to address all these issues in the spirit of Web3.

On the privacy side of the equation, privacy-centric blockchain platforms are emerging such as Aleo, which is using a cryptographic technique known as zero-knowledge proofs (ZKPs) to enable the development of private applications on blockchain. That technology allows transactions to be executed off-chain while remaining verifiable by allowing a statement or fact to be proved true without revealing what makes it so. Similarly, Zcash offers a digital currency with shielded transactions to keep financial information private using similar technology which makes use of viewing keys to selectively disclose data.

Potential Regulatory Bodies

Despite such initiatives, off-chain organisations from investment groups to nations states are already outlining ways of approaching these issues – for good or for ill, depending on your viewpoint. Look no further than the U.S. Securities and Exchange Commission (SEC) is making a concerted push into regulating cryptocurrencies with litigation against Ripple Labs and its digital currency XRP, for instance.

Meanwhile, venture capital firm Andreessen Horowitz (a16z), one of the largest Web3 investors, has outlined its vision of Web3 regulation and its eagerness to work with policymakers to make it a reality. Among its suggestions are bringing in legislation to make decentralized autonomous organizations (DAOs) an official mode of organization as a potential successor to corporations. Similarly, they advocate not treating the whole of Web3 as a monolith, saying “policymakers should focus on calibrating regulatory activities to the specific applications and their associated risks.”

Another approach is that of the OASIS Consortium, which is advocating building safety procedures into the infrastructure of next-generation internet platforms at their core. The consortium is formed of members from metaverse builders, industry organizations, academia and non-profits, government agencies, and advertisers, with the group having just released a set of standards for ethical online behaviours in Web3 prioritising openness, accountability, security, innovation and sustainability.

Its standards were developed with input from existing gaming, dating and social applications in an effort to get platforms to self-regulate via pledges to user safety standards. While the full extent of the adoption of such standards is yet to be seen, the consortium has secured the pledges of luminaries such as advertising and PR giant Dentsu, as well as The Meet Group, Fandom, Pandora and others.

Ultimately, successfully regulating the metaverse may require collaboration between all of the approaches mentioned so far – whether platforms, users, governments, or decentralized tools. What seems clear is that Web3 platforms will have to consider the best approaches to operating ethically early, learning the lessons of Web 2.0 in order to avoid the fallout that is currently engulfing the giants of today.

Demystifying Ethereum Token Standards

The Ethereum blockchain has risen to popularity on the back of its programmable nature, allowing for the construction of decentralized applications, smart contracts, NFTs (non-fungible tokens) and cryptocurrencies. 

Those seeking to better understand the platform will doubtless have come across terms such as ERC-223 and ERC-777 and wondered what they refer to. Simply put, they refer to community standards that have been officially adopted by the blockchain, allowing developers to build interoperable tokens that behave in predictable ways.

If you’re still scratching your head, read on to avoid the crushing embarrassment of confusing your ERC-20s for your ERC-721s.

Why Have Different Token Standards?

The list of things that can be accomplished on a blockchain is ever-expanding. Left alone, however, every new innovation would have to rebuild from the ground up. Token standards are there to ensure the foundations are already laid and to ensure compatibility between tokens on the same standard and the smart contracts that issue them. That way, when a new token is issued, it remains compatible with existing decentralized exchanges, for instance. 

The prefix ERC itself stands for “Ethereum Request for Comments”, and refers to application-level standards and conventions. Token standards are just one type among more than 20 finalized standards contained within the category, with many more in the review and draft stage. Aside from tokens, they cover everything from wallets to smart contracts.

Let’s take a closer look at some of the token standards to see how exactly they differ from one another.

ERC-20

First proposed in 2015, ERC-20 is perhaps the most important standard, a basic understanding that fungible (interchangeable) tokens on the Ethereum network rely on – whether they are virtual currencies, voting tokens or anything in between. Popular ERC-20 tokens include Chainlink ($LINK) and Tether ($USDT).

The standard contains a list of rules dictating things like the total token supply, how tokens can be transferred, and how transactions are approved. The six mandatory code functions of the standard are: totalSupply, balanceOf, transfer, transferFrom, approve and allowance.

Taken together, these act as a standard interface for enabling all aspects of the sending and receiving of ERC-20 tokens. But the standard was found to have some issues, not least the existence of a bug in the transfer function where tokens can be transferred to an incompatible account and destroyed in the process.

ERC-223 

That spurred the development of new standards such as ERC-223, which has the capacity to display errors and cancel faulty transactions. A new function is included in the standard,  tokenFallback, which ensures that tokens can only be sent to smart contracts with the appropriate functionality. If they are not, only the gas fee is wasted.

ERC-721

Both aforementioned token standards are for fungible tokens, but ERC-721 is the standard interface for non-fungible tokens. That means tokens that are non-interchangeable and therefore unique. They are typically used to prove ownership of a particular digital asset, with the technology powering the boom in PFP series such as CryptoKitties.

The standard enables smart contracts to issue tokens that have different values to other tokens issued from the same smart contract. As such, NFTs have a variable tokenId that makes them unique. Web 3 applications are able to read that and convert it into a unique output such as the combination of accessories on a character, or a specific seat for a physical event. 

ERC-777

ERC-777 is another fungible token standard improving over ERC-20. Instead of mostly being about fixing bugs like ERC-223, ERC-777 actually extends token functionality with new features. It was designed to make token transfers easier, allowing developers to know whether a smart contract can receive tokens before they are sent, for instance. The standard also offers more control to users with the ability to black- and whitelist addresses, as well as being backwards compatible with ERC-20.

ERC-1155

Finally, ERC-1155 is notable for being a token standard that can contain both fungible and non-fungible assets, allowing a smart contract to deal with a combination of token types such as ERC-20 and ERC-721. The thinking behind the standard is to simplify transactions involving both kinds of token while also fixing problems with ERC-20 and ERC-721 standards. That means more efficient trades and the bundling of transactions to reduce gas fees.

All these standards originated as Ethereum Improvement Proposals which are creatable by anyone but must garner support from the community before being adopted. If you have any ideas for the next generation of Ethereum token standards, get involved!

Stay tuned for more!

So, which events are you most excited about this year? Or which ones will you be attending? We’d love to hear your thoughts!

We’ve also heard about more conferences coming up in the future. To stay informed, be sure to have a look at our public spreadsheet (which we’ll be updating regularly).

What is an NFT?

As we move closer to embracing Web3, there are more and more terms for new technologies emerging. Getting to grips with a new technology or phrase can be daunting. Perhaps you’re one of the millions of people who began to hear the term ‘NFT’ in 2020-21 and thought, “what the heck is an NFT?” Or maybe you know a little but would like to learn more. We’ve got the basics covered!

Fungible ?

What does the word ‘fungible’ actually mean? Fungible is “an item which is replaceable by another identical item; [an item which is] mutually interchangeable” Let’s use clothes shopping to illustrate this meaning. 

We love a particular pair of sneakers, we can order these from an online retailer or buy them from a physical store. When we buy them, the retailer can pick any box and sell them to us. It doesn’t matter which pair they pick off the shelf as they’re exactly the same. Once they’ve been worn, and worn out, we can buy another identical pair. We could even stockpile them because we love them so much; there are thousands of pairs in the world, after all. 

So, fungible = replaceable.

Non-fungible ?

Now to look at the opposite – non-fungible. As you’ve probably guessed, this means something which is irreplaceable. For example, the painting ‘Sunflowers’ by Vincent Van Gogh is irreplaceable – there is only one of these in the entire world. Were this painting to be destroyed, there would be copies of it in existence, but they are not the Van Gogh masterpiece.

So, non-fungible = not replaceable.

Token?

An NFT is a strictly digital item, it only exists digitally, there is no physical version, though it can represent something from the physical world. The NFT is basically a token; an alphanumeric code that tokenises the digital item turning it into something you can own. Imagine it as a signature on a painting, the token represents Van Gogh’s signature declaring the NFT as the original.

The token exists on the blockchain and, via the alphanumeric code signature, it can be tracked and traced via public records to show that you own it. We’ll come back to the blockchain soon.

Right-clicking?

One of the major arguments against NFTs is that the image or gif can be ‘right-clicked’ and saved to a PC or mobile phone. This argument is usually used to show that you can’t ‘own’ the item within the NFT.

Hopefully, you’re old enough to remember film-based cameras because we’re going to use them in this example (if not, it’s time to imagine!):

Before digital cameras became mainstream, film cameras were used by everyone. Once you snapped a photo the image would be stored as a negative on the roll of film. You’d send off the film for printing and receive a package of photos along with the original negatives.

Using that negative, you could feasibly produce hundreds of thousands of copies of a particular image, but only you own the negative – the original source of the image. That photo could be given to everyone in the world, be photocopied, scanned and reprinted infinitely, but the negative is the original and you own it. So, if for example, those millions of copies somehow were destroyed, you’d still have your original negative.

Buying an NFT of a tweet, or a digital Banksy, doesn’t stop others reproducing the image, but the token in the NFT declares to the world that you own the original as bought from the creator, you hold the negative. It’s no different to the physical art world; Sunflowers is hanging in the National Gallery London and it can never be replaced, but the gift shop sells imitation posters to take home. Remember:

Sunflowers = Non-fungible.

Poster of Sunflowers = Fungible.

How does the blockchain work?

For an in-depth look at blockchain technology, please see our accompanying tutorial [we’ll need a link here]. For a fast and dirty explanation, we’ll get into it now.

The blockchain is a huge spinal cord, where each vertebra is a computer. Those computers are owned by people the world over. These computers exist to crunch numbers and verify transactions. When somebody buys something, the computers all talk to each other to establish the buyer has the money and the seller has the product. Once the purchase is complete, it adds a new block to the chain filled with information about the transaction.

Where this differs from a centralised business is in the public records. Every single transaction on the blockchain is open to the public, plus there is no middle man. There is no art gallery to take a cut of the profits. It’s also incredibly difficult, on the largest blockchains, to steal or commit fraud, because if just one computer notices a bad transaction, it won’t create a block and the money will not be transferred.

What can be an NFT?

Pretty much everything. Yes, an NFT can be a computer-generated image of an ape or a kitten; it can also be a music track, a short video or gif, or it can simply store information and data. If it’s digital and, most importantly, original, then it can be an NFT.

Because of this, you’ll have noticed that NFT marketplaces are overflowing with NFTs of varying media and seemingly every major company is looking for a way into the market. It’s also very easy to mint (create) an NFT, meaning a lot of people are hoping to create the next big movement in the space.

Gas fees?

Whenever a transaction is started on a blockchain – it can be any of the blockchains, Ethereum, Bitcoin, Tezos, etc – an amount is paid to the miners who own the computers computing the transaction. Imagine it as tipping your waiter. They didn’t cook the food, but they were an integral part of the chain in bringing it to your table.

Miners usually receive a small fraction of the transaction cost, though this is determined by the cryptocurrency prices. If a crypto is generally expensive to use, then the cost in gas fees will feel more expensive, because it’s a percentage of the crypto price.

In some instances, gas fees can be lower for the buyer. A general rule of thumb is: if you want the transaction to be computed swiftly, the gas fees will be higher, as it will take up more energy to process at speed. Slower transaction checking means lower gas fee totals. In many situations, the gas fees will be proportionately lower than usual middleman fees found in transactions today.

What are the Upsides?

NFT technology has the potential to completely revolutionise the internet and the way data is stored and transferred. Because anything can be an NFT, the blockchain can store the data forever, and that data can be constantly referred to. The technology can vitally change the sale of goods.

For example, we want to buy a house from our friend. Our friend owns the property – the deed has been digitised and minted as an NFT – and they want 23 crypto for the selling price. We have 23 crypto in our digital wallet and begin the transaction to buy the NFT deed.

Once the blockchain has confirmed that our friend indeed owns the house (digital deed) and we have the 23 crypto, the exchange is done and recorded on the blockchain. Everyone can see we now own the deed to the physical house, our friend has their funds which can be withdrawn or spent and now we can move in. In this example, the agency that would usually deal with this transaction is completely removed. There’s no need to pay fees or fill out reams of paperwork.

NFTs can also open up creator economies, allowing artists, musicians and millions of other creators to sell directly to their audience. They can also be used by governmental bodies to track information in utilities, population, building and traffic data, eliminating email chains, paper backups and miscommunication.

What are the Downsides?

Firstly, NFT technology can be very confusing – hopefully, we’re helping to eliminate this. There’s blockchain, tokens, types of cryptocurrency, wallets, gas fees, minting… the list goes on. Any emerging technology is going to feel initially overwhelming, but with time these processes will become easier to deal with or be streamlined.

Secondly, the NFT market and cryptocurrency generally, can be very volatile. One minute prices are low, the next minute they’re very high. Like the stock market, there will be fluctuations constantly. Buying an NFT isn’t only about whether you like or appreciate the content, it’s also about getting a fair price. Whenever you want to buy an NFT, you must research the artist, the market, the crypto costing, the gas fees, all to ensure you’re getting the best deal.

Lastly, there’s the environmental impact. All those computing decisions and transaction checks use energy and, of course, that energy is normally generated by burning fossil fuels which spew carbon into the atmosphere and impact the Earth via climate change. However, we are at a crossover point – if this technology begins to be used widely, other systems like gold mining and global banking will depend on fossil fuels less, hopefully balancing the usage. 

We also need to remember that as the energy industry changes and embraces cleaner options the environmental impact will decrease. On top of that, some blockchains are using much less energy than others – for example, the Tezos network – or applying a carbon offset into their business.

We can see the yearly approximate energy breakdowns as follows (TWh = TerraWatthour) for 2021:

  • Gold industry – 240.61 TWh
  • Global Banking System – 238.92 TWh
  • Bitcoin Network – 113.89 TWh
  • Ethereum Network – 44.5 TWh
  • Tezos Network – 0.001 TWh

Hopefully, this has helped you learn more about NFTs. Now you should be able to navigate this new phase in the evolution of the internet and the digital economy. If you’d like more information or want to go into more detail with NFTs and Web3, keep reading gmw3.
