Play-to-earn brings much-needed change to the gaming industry

Play-to-earn may be the hottest word in the whole gaming industry. Check how you can join the trend that rocks players all around the globe!

Earing by playing games isn’t necessarily a new idea. Even 20 years ago best players of such games as Diablo II or Runescape were able to make money on selling digital assets they acquired during the game. Not to mention the professional players, who in the last decade became able to generate significant profits from their e-sport activity. 

Yet, through time many new restrictions emerged, making earning from playing more and more difficult for amateur players. Of course, solutions such as Steam marketplace are available. Yet, they are not free from burdensome limitations. For example, on Steam it’s not possible to withdraw money from your account. Other ways of trading in-game assets, which involved less popular or not adapted platforms, often fail when it comes to security. 

NFTs may give us a chance to change it. And everything indicates that players are interested. 

What does play-to-earn mean?

Essentially play-to-earn refer to earning real profits just by… playing. Simple, right? As we mentioned the core idea isn’t new. Yet, it is thanks to modern solutions such as NTF, that this phenomenon may be facilitated for the broader audience.

Currently, play-to-earn is most often used in the context of so-called crypto games. These gaming platforms allow their users to earn their native cryptocurrency during the game. For example, users can get tokens for winning fights or selling limited items. Eventually, those tokens can be exchanged for other cryptocurrencies or fiat money.

Why are investors interested in launching their own crypto games? With the growth of the game’s environment, the value of the game’s native currency increased as well. The more players game has, the more transactions are facilitated in-game, and eventually the higher demand for the currency is. 

Play-to-earn gaming and crypto games are two phenomenons highly connected with each other. Hence, to bring closer the first one, we will also discuss the second.

Crypto games

Crypto games are without a doubt the hottest trend in the Blockchain industry. Despite a modest start, crypto games slowly became one of the most revolutionizing factors in the modern gaming landscape. From CryptoKitties, through NBA Top Shot, to Axie Infinity - crypto games from simple collectible games have grown into revolutionary projects, which influence goes far beyond the gaming industry. How was it possible? All thanks to NFT tokens…

Yes, that’s right. You hear about NFT almost everywhere. Collins dictionary even named NFT the Word of the Year for 2021! But among all NFT’s implementations, one seems to be particularly exciting for blockchain entrepreneurs - games. Recent events, such as Immutable X’s ICO, show us how important this branch became for the whole industry. 

How NFTs may be used in video games? Below we briefly described that issue. 

What are NFTs?

NFTs - 2021 was definitely their year. Spectacular events, such as record-breaking art sales, incredibly expensive virtual land plots, or fashion icons launching their own NFT collections made headlines all across the globe. Here you can find more about particularly significant NFT projects from 2021. But besides a buzzword, what exactly are NFTs? 

NFT stands for non-fungible token. Non-fungibility means that every token in the system is unique. NFTs don’t have a common value and often do not allow for an equal exchange (NFT for NFT). Each token represents unique information of ownership or identity.  

Among various blockchain token types, we differentiate between fungible and non-fungible tokens. (You can read here more about token types) Examples of the first kind are Bitcoin or Ether. Fungible means that a single token is indistinguishable from others in the same ecosystem. Just like in regular currency. Thus, they can be used for payment transactions. 

Although NFT tokens became popular just recently, they’ve been with us for much longer. First, and still most popular NFT standard - ERC was created in 2016. Yet, for a long time, NFTs were left in the shadow of their fungible counterparts. This year delivered dozens of groundbreaking projects that changed this trend. 

NFT games 

NFT games are almost as old as NFTs themselves. After all their first commercial usage was a game: CryptoKitties. The game allows players to buy, collect, and sell virtual kitties, which are saved on blockchain as NFTs. Since the game’s debut in 2017, its creators - Dapper Labbs made over $40 million on it. 

CryptoKitties were the first game of this kind which started a whole new trend. Yet, the recent projects enabled us to unlock the true potential of NFT, which goes far beyond simple collectibles.

NFT and gaming assets 

Everywhere where users collect and trade virtual gaming assets, NFTs can highly improve their gaming experience. Essentially, they assure players about the authenticity and scarcity of gaming assets and allow them to keep full ownership of the purchased assets. 

As an example, let’s take multiplayer games like the aforementioned LOL or Fortnite. Possessed skins and champions are of great importance to the players. What if the players had complete control over the ownership rights to their game assets?

Play-to-earn gaming

Ok, all of that sounds tremendous. But what the whole industry is talking about are play-to-earn possibilities that NFTs bring. As creators of one of the top NFT games - God’s Unchained, say: “You don’t own assets if you can’t sell them”. This is the main idea behind the majority of NFT games right now. Their game itself is one of the projects that aim to enable players to earn on in-game assets saved as NFT. But how exactly do NFTs facilitate play-to-earn?

Let’s imagine an online card game where users unclocked new characters and equipment by participating in a quest and winning fights. What if they would like to sell their character? Many games of this type actually allowed players to do so. Yet, often it’s only possible in exchange for the game’s coins which don’t represent any real value. Furthermore, such coins are usually characterized by the same problem as any other in-game assets - players don’t possess any ownership rights to them.

As we mentioned before, NFTs are unique digital assets that represent encoded information about their identity and ownership. There is a thing with blockchain: changing such data requires consensus reached among every node. In practice, it means that NFTs can be considered as authenticity and ownership certificates of themselves. Moreover, every action involving NFT is extremely treatable and secured against fraud. 

Therefore, saving in-game assets as NFTs allowed players to possess ownership rights to them. Such assets can be traded on both internal and external marketplace. Sometimes for fiat currencies or popular cryptocurrencies, sometimes for the game’s native tokens, which then can be eventually exchanged for “real money”. This is how NFT may unlock true play-to-earn possibilities in numerous types of games. We listed just a few of them: 

Games’ native tokens are another phenomenon that deserves our attention. In contrast to the usual game’s coins, those tokens can be listed on external exchanges, and represent particular value even outside the game. Why? In case of their case, fungible tokens are used. Therefore, essentially we can speak about game-specific cryptocurrencies. What’s important for games’ creators, those tokens gain value, with the game ecosystem’s growth. 

Scarcity is nothing new for the gaming industry. Unique skins, armors, and other digital assets are commonly present in it almost from the begging. Through the years different markets have been created to facilitate users’ trade. Yet, there were always limitations. For example, usually direct exchanges to “real money” were impossible. NFT may change that for good. 

As we mentioned, gamming assets saved as NFT can be traded on both internal and external marketplace. The same goes to games’ native currencies. What’s important, this trade can be decentralized. 

It needs to be noted that behind video games stands an industry worth over $330 billion. Play-to-earn gaming my by a way to share part of this spectacular growth with players. 

The new generation of embed finance?

Although paying a real-life rant fee in game’s coins may sound absurd, it already happens. Axie Infinity is a blockchain game that enables players to earn native tokens by winning fights and selling avatars. Eventually, those tokens can be exchanged for other cryptocurrencies or fiat money on external exchanges. Therefore, without a doubt we can speak about the truly play-to-earn game.

Yet, what’s unique about Axis is the unpredicted implementation of the game’s native tokens that emerged in the Philippines, where the game has 40 % of its players. According to Sky Mavis for 25% of Axie's players, the game's wallet is the first financial service they’ve been able to access. Arianna Simpson, a partner at Andreessen Horowitz - one of Axie's main investors, claims that in some places in the Philippines people are even paying their rent with the game’s tokens.

Axie Infinity

The public heard about Axie Infinity for the first time after the spectacular sale of a digital land plot. In February 2021, user Flying Falcon bought eight genesis plots worth approximately $1.5mln. This event may be considered a milestone for the NFT market. But what is so special about Axie Infinity?

Axie resembles Pokemon, but on a Blockchain. The core of the game is combat between cartoon characters - Axies. What differentiates Axies from Pokemons is the fact that they are NFTs stored on the game’s Blockchain. Essentially they are NFTs-based digital creatures.

To create new characters, players “breed” them using the game’s native token, which can be earned through the game or bought from an exchange. By selling Axies or winning fights, players earned the currencies. Then they can sell them on the open market, making a profit.

Currently, dedicated players earn as much as thousands of dollars a month playing Axie Infinity. 

Play-to-earn games: God's Unchained

God’s Unchained 

If you are up to date with the ICOs’ world, without a doubt, you’ve heard about Immutable X. Get to know the blockchain game created by its godfathers.

Gods Unchained is a trading card game that aims to give its players complete ownership over in-game items by using NFTs. Essentially its players collect digital playing card NFTs

Their motto is, “If you can’t sell your items, you don’t own them.” Thus the game allows users to sell their cards and other items for native GODS tokens, which can be exchanged for fiat money. 

It’s worth noting that God’s Unchained remains a free-to-play game. Cards can be unlocked simply by playing the game. Therefore Gods Unchained should be considered one of the truly play-to-earn games, which stands contrary to the standard model of gaming commerce.

Play-to-earn games: The Sandbox
Play-to-earn games: The Sandbox

The Sandbox

The Sandbox is one of the NFT-based games that created their own metaverses. To date, it is one of the most popular NFT games for creating and trading in-game assets.

Like Minecraft or Roblox, this NFT game is voxel-based and offers an excellent opportunity to free users’ creativity. The Sandbox provides them with tools for creating and animating NFT objects that can be used in-game or sold on designed markets. But that’s not all - on the platform, users can also develop and play their games. Since users are able to make real money on their creations, The Sandbox is another example of play to earn the game.

Does play-to-earn gamming predicts how metaverse will look like

It’s no secret that many NFT games describe themselves as blockchain-based metaverses. Just take Sandbox as an example. According to many similar models of transection that we can observe in NFT games will be also present in metaverses. Without a doubt, there are significant factors that make them suitable for that purpose.

Implementing play-to-earn model

If you consider launching your own NFT game that will facilitate a play-to-earn model, you should be aware that its success requires skills and knowledge regarding both the technical and business sides of the Blockchain industry. That’s why many projects decide to hire an external blockchain company as a technological partner.

At Nextrope, we can call ourselves pioneers of Blockchain technology in CEE. We conducted one of the first tokenization in the world and since that we keep up to date with the industry. NFT games aren’t an exception.

Applying Game Theory in Token Design

Kajetan Olas

Applying Game Theory in Token Design

Blockchain technology allows for aligning incentives among network participants by rewarding desired behaviors with tokens.
But there is more to it than simply fostering cooperation. Game theory allows for designing incentive-machines that can't be turned-off and resemble artificial life.

Emergent Optimization

Game theory provides a robust framework for analyzing strategic interactions with mathematical models, which is particularly useful in blockchain environments where multiple stakeholders interact within a set of predefined rules. By applying this framework to token systems, developers can design systems that influence the emergent behaviors of network participants. This ensures the stability and effectiveness of the ecosystem.

Bonding Curves

Bonding curves are tool used in token design to manage the relationship between price and token supply predictably. Essentially, a bonding curve is a mathematical curve that defines the price of a token based on its supply. The more tokens that are bought, the higher the price climbs, and vice versa. This model incentivizes early adoption and can help stabilize a token’s economy over time.

For example, a bonding curve could be designed to slow down price increases after certain milestones are reached, thus preventing speculative bubbles and encouraging steadier, more organic growth.

The Case of Bitcoin

Bitcoin’s design incorporates game theory, most notably through its consensus mechanism of proof-of-work (PoW). Its reward function optimizes for security (hashrate) by optimizing for maximum electricity usage. Therefore, optimizing for its legitimate goal of being secure also inadvertently optimizes for corrupting natural environment. Another emergent outcome of PoW is the creation of mining pools, that increase centralization.

The Paperclip Maximizer and the dangers of blockchain economy

What’s the connection between AI from the story and decentralized economies? Blockchain-based incentive systems also can’t be turned off. This means that if we design an incentive system that optimizes towards a wrong objective, we might be unable to change it. Bitcoin critics argue that the PoW consensus mechanism optimizes toward destroying planet Earth.

Layer 2 Solutions

Layer 2 solutions are built on the understanding that the security provided by this core kernel of certainty can be used as an anchor. This anchor then supports additional economic mechanisms that operate off the blockchain, extending the utility of public blockchains like Ethereum. These mechanisms include state channels, sidechains, or plasma, each offering a way to conduct transactions off-chain while still being able to refer back to the anchored security of the main chain if necessary.

Conceptual Example of State Channels

State channels allow participants to perform numerous transactions off-chain, with the blockchain serving as a backstop in case of disputes or malfeasance.

Consider two players, Alice and Bob, who want to play a game of tic-tac-toe with stakes in Ethereum. The naive approach would be to interact directly with a smart contract for every move, which would be slow and costly. Instead, they can use a state channel for their game.

  1. Opening the Channel: They start by deploying a "Judge" smart contract on Ethereum, which holds the 1 ETH wager. The contract knows the rules of the game and the identities of the players.
  2. Playing the Game: Alice and Bob play the game off-chain by signing each move as transactions, which are exchanged directly between them but not broadcast to the blockchain. Each transaction includes a nonce to ensure moves are kept in order.
  3. Closing the Channel: When the game ends, the final state (i.e., the sequence of moves) is sent to the Judge contract, which pays out the wager to the winner after confirming both parties agree on the outcome.

A threat stronger than the execution

If Bob tries to cheat by submitting an old state where he was winning, Alice can challenge this during a dispute period by submitting a newer signed state. The Judge contract can verify the authenticity and order of these states due to the nonces, ensuring the integrity of the game. Thus, the mere threat of execution (submitting the state to the blockchain and having the fraud exposed) secures the off-chain interactions.

Game Theory in Practice

Understanding the application of game theory within blockchain and token ecosystems requires a structured approach to analyzing how stakeholders interact, defining possible actions they can take, and understanding the causal relationships within the system. This structured analysis helps in creating effective strategies that ensure the system operates as intended.

Stakeholder Analysis

Identifying Stakeholders

The first step in applying game theory effectively is identifying all relevant stakeholders within the ecosystem. This includes direct participants such as users, miners, and developers but also external entities like regulators, potential attackers, and partner organizations. Understanding who the stakeholders are and what their interests and capabilities are is crucial for predicting how they might interact within the system.

Stakeholders in blockchain development for systems engineering

Assessing Incentives and Capabilities

Each stakeholder has different motivations and resources at their disposal. For instance, miners are motivated by block rewards and transaction fees, while users seek fast, secure, and cheap transactions. Clearly defining these incentives helps in predicting how changes to the system’s rules and parameters might influence their behaviors.

Defining Action Space

Possible Actions

The action space encompasses all possible decisions or strategies stakeholders can employ in response to the ecosystem's dynamics. For example, a miner might choose to increase computational power, a user might decide to hold or sell tokens, and a developer might propose changes to the protocol.

Constraints and Opportunities

Understanding the constraints (such as economic costs, technological limitations, and regulatory frameworks) and opportunities (such as new technological advancements or changes in market demand) within which these actions take place is vital. This helps in modeling potential strategies stakeholders might adopt.

Causal Relationships Diagram

Mapping Interactions

Creating a diagram that represents the causal relationships between different actions and outcomes within the ecosystem can illuminate how complex interactions unfold. This diagram helps in identifying which variables influence others and how they do so, making it easier to predict the outcomes of certain actions.

Artonomus, Github

Analyzing Impact

By examining the causal relationships, developers and system designers can identify critical leverage points where small changes could have significant impacts. This analysis is crucial for enhancing system stability and ensuring its efficiency.

Feedback Loops

Understanding feedback loops within a blockchain ecosystem is critical as they can significantly amplify or mitigate the effects of changes within the system. These loops can reinforce or counteract trends, leading to rapid growth or decline.

Reinforcing Loops

Reinforcing loops are feedback mechanisms that amplify the effects of a trend or action. For example, increased adoption of a blockchain platform can lead to more developers creating applications on it, which in turn leads to further adoption. This positive feedback loop can drive rapid growth and success.

Death Spiral

Conversely, a death spiral is a type of reinforcing loop that leads to negative outcomes. An example might be the increasing cost of transaction fees leading to decreased usage of the blockchain, which reduces the incentive for miners to secure the network, further decreasing system performance and user adoption. Identifying potential death spirals early is crucial for maintaining the ecosystem's health.

Token Engineering Process

Token Engineering Process

Token Engineering is an emerging field that addresses the systematic design and engineering of blockchain-based tokens. It applies rigorous mathematical methods from the Complex Systems Engineering discipline to tokenomics design.

In this article, we will walk through the Token Engineering Process and break it down into three key stages. Discovery Phase, Design Phase, and Deployment Phase.

Discovery Phase of Token Engineering Process

The first stage of the token engineering process is the Discovery Phase. It focuses on constructing high-level business plans, defining objectives, and identifying problems to be solved. That phase is also the time when token engineers first define key stakeholders in the project.

Defining the Problem

This may seem counterintuitive. Why would we start with the problem when designing tokenomics? Shouldn’t we start with more down-to-earth matters like token supply? The answer is No. Tokens are a medium for creating and exchanging value within a project’s ecosystem. Since crypto projects draw their value from solving problems that can’t be solved through TradFi mechanisms, their tokenomics should reflect that. 

The industry standard, developed by McKinsey & Co. and adapted to token engineering purposes by Outlier Ventures, is structuring the problem through a logic tree, following MECE.
MECE stands for Mutually Exclusive, Collectively Exhaustive. Mutually Exclusive means that problems in the tree should not overlap. Collectively Exhaustive means that the tree should cover all issues.

In practice, the “Problem” should be replaced by a whole problem statement worksheet. The same will hold for some of the boxes.
A commonly used tool for designing these kinds of diagrams is the Miro whiteboard.

Identifying Stakeholders and Value Flows in Token Engineering

This part is about identifying all relevant actors in the ecosystem and how value flows between them. To illustrate what we mean let’s consider an example of NFT marketplace. In its case, relevant actors might be sellers, buyers, NFT creators, and a marketplace owner. Possible value flow when conducting a transaction might be: buyer gets rid of his tokens, seller gets some of them, marketplace owner gets some of them as fees, and NFT creators get some of them as royalties.

Incentive Mechanisms Canvas

The last part of what we consider to be in the Discovery Phase is filling the Incentive Mechanisms Canvas. After successfully identifying value flows in the previous stage, token engineers search for frictions to desired behaviors and point out the undesired behaviors. For example, friction to activity on an NFT marketplace might be respecting royalty fees by marketplace owners since it reduces value flowing to the seller.

Design Phase of Token Engineering Process

The second stage of the Token Engineering Process is the Design Phase in which you make use of high-level descriptions from the previous step to come up with a specific design of the project. This will include everything that can be usually found in crypto whitepapers (e.g. governance mechanisms, incentive mechanisms, token supply, etc). After finishing the design, token engineers should represent the whole value flow and transactional logic on detailed visual diagrams. These diagrams will be a basis for creating mathematical models in the Deployment Phase.

Objective Function

Every crypto project has some objective. The objective can consist of many goals, such as decentralization or token price. The objective function is a mathematical function assigning weights to different factors that influence the main objective in the order of their importance. This function will be a reference for machine learning algorithms in the next steps. They will try to find quantitative parameters (e.g. network fees) that maximize the output of this function.
Modified Metcalfe’s Law can serve as an inspiration during that step. It’s a framework for valuing crypto projects, but we believe that after adjustments it can also be used in this context.

Deployment Phase of Token Engineering Process

The Deployment Phase is final, but also the most demanding step in the process. It involves the implementation of machine learning algorithms that test our assumptions and optimize quantitative parameters. Token Engineering draws from Nassim Taleb’s concept of Antifragility and extensively uses feedback loops to make a system that gains from arising shocks.

Agent-based Modelling 

In agent-based modeling, we describe a set of behaviors and goals displayed by each agent participating in the system (this is why previous steps focused so much on describing stakeholders). Each agent is controlled by an autonomous AI and continuously optimizes his strategy. He learns from his experience and can mimic the behavior of other agents if he finds it effective (Reinforced Learning). This approach allows for mimicking real users, who adapt their strategies with time. An example adaptive agent would be a cryptocurrency trader, who changes his trading strategy in response to experiencing a loss of money.

Monte Carlo Simulations

Token Engineers use the Monte Carlo method to simulate the consequences of various possible interactions while taking into account the probability of their occurrence. By running a large number of simulations it’s possible to stress-test the project in multiple scenarios and identify emergent risks.

Testnet Deployment

If possible, it's highly beneficial for projects to extend the testing phase even further by letting real users use the network. Idea is the same as in agent-based testing - continuous optimization based on provided metrics. Furthermore, in case the project considers airdropping its tokens, giving them to early users is a great strategy. Even though part of the activity will be disingenuine and airdrop-oriented, such strategy still works better than most.

Time Duration

Token engineering process may take from as little as 2 weeks to as much as 5 months. It depends on the project category (Layer 1 protocol will require more time, than a simple DApp), and security requirements. For example, a bank issuing its digital token will have a very low risk tolerance.

Required Skills for Token Engineering

Token engineering is a multidisciplinary field and requires a great amount of specialized knowledge. Key knowledge areas are:

  • Systems Engineering
  • Machine Learning
  • Market Research
  • Capital Markets
  • Current trends in Web3
  • Blockchain Engineering
  • Statistics

Summary

The token engineering process consists of 3 steps: Discovery Phase, Design Phase, and Deployment Phase. It’s utilized mostly by established blockchain projects, and financial institutions like the International Monetary Fund. Even though it’s a very resource-consuming process, we believe it’s worth it. Projects that went through scrupulous design and testing before launch are much more likely to receive VC funding and be in the 10% of crypto projects that survive the bear market. Going through that process also has a symbolic meaning - it shows that the project is long-term oriented.
