How to create NFT games? – A practical guide

NFT games are entertainment products that are based on blockchain technology and tokens. More and more entities use NFT to monetize their ventures in the gaming industry. This allows players to create, sell, or buy tokens of any game-related object while providing financial support to the game's developer. How does it work in practice? How to create an NFT game? We're writing about it below!

Who profits from NFT games?

With NFT, creators can tokenize and sell skins, artifacts, armor, weapons, etc. in a given form. NFT can be used not only by developers, but also by players. For example, they have the ability to sell NFT in-game to other collectors and players, thus earning money and cryptocurrency.

How to start making an NFT game?

In order to design and utilize NFT in-game, developers create smart contacts that automate the use of tokens. An example of this is the most popular blockchain game – CryptoKitties, where several smart contracts create a structure for the entire game! As for smart contracts, a good example is GeneScience, which defines a random mechanic in order to generate new cats. In addition to smart contracts, there are other things to consider when creating an NFT game.

NFT GAMES

NFT game model

There are currently two most popular forms of NFT games:

  1. P2E (play to earn) - gameplay will only start when you purchase the NFT token. This does not change the fact that in the future there will be an opportunity to treat the game as a potential investment.
  2. F2P (free to play) - it's a unique form of entertainment that cuts down on initial costs. You can play it immediately, free of charge. When you create a game in this respect, you may find that potential revenue is lower than P2E. Such games do not have NFT in useable form. Older players teach younger players in order to participate in later profits.

NFT game genre

Select the genre of game that will be targeted at potential users. Keep in mind that an NFT game is very similar to a classic game. The difference will only be the monetization of your product. A number of genres are therefore available for selection:

  • adventure games,
  • RPG’s,
  • story driven games,
  • card games,
  • strategy games,
  • war games and many more.

After choosing a genre, analyze the competition. It may be worthwhile to check out similar games using blockchain technology. Don't copy games that have not been successful. Some choose a solution that takes advantage of the best and most interesting features from the competition’s projects. All information regarding the game should be written down and recorded in the game's design document. This will help you avoid the issue of your team not understanding your vision of the project. Designing proper and transparent stages of game development, including levels, conditions of promotion and monetization, will help to avoid misunderstandings. When you achieve this, move on to designing the visuals.

Application availability

Applications built on blockchain technology have their own dApps name, meaning they are decentralized. This is important because the main code and data of the decentralized application are stored in a peer-to-peer blockchain. This is the opposite of a client-server application where information resides on servers that are easy to hack. Emphasis should be placed on decentralization, as every cryptocurrency is decentralized. In addition, decentralized applications are open source.

Mobile app vs Web browser

Another element to consider is how your customers will use the game. Reactions can be based on a web browser or a mobile application. Both forms are attractive for NFT implementation. The web application is widespread and can be started from almost any device. The mobile app will certainly work better on smartphones and offers many unique features.

Mobile applications – division

Mobile applications can be divided into native and cross-platform forms.

  1. Native form – applications are created for a specific operating system and provide access to a variety of smartphone features: camera, contact list, GPS, and more.
  2. Cross-platform form – Cross-platform options will not have access to smartphone features, but they are much easier, faster, and less expensive to create. This is because you need only one solution that will work on all operating systems.

Whichever feature you choose, consider whether your game can be used on a smartphone. Moreover, AppStore has a number of requirements and restrictions for gaming apps. There is also the hybrid application, which is both a mobile and web application.

Selection of technologies for NFT games

Encorporating NFT into video games is best done using open source. One of the most popular ecosystems for making games with NFT is the dApp "Truffle Suite". It is the best place to develop smart contracts. Truffle Suite is used by entities such as Microsoft, Amazon or VMWare. This solution provides blockchain developers with a standard and schematic environment to test potential smart contracts in gaming. As for the best blockchain to build an NFT game on – that would be Ethereum. It's the most popular platform for creating and running NFT – also in gaming, where it enjoys the greatest popularity.

Truffle Suite is comprised of three different elements:

  • Truffle – is an environment for developers who use Ethereum as a basis for creating NFT and implementing and using smart contracts.
  • Ganache – is a tool that allows you to configure the local Ethereum blockchain. This ensures that decentralized applications can be deployed, developed and tested in a secure location.
  • Drizzle – is a set of front-end libraries designed to develop and create a transparent interface.

Front-end

This element can be created using Javascript. You will need the right Framework, which will guarantee a set of specific software solutions. This will give us the design, logic and basic functions of the game. In addition, some tasks allow the creator of an NFT game to add their own code to a package created in a Framework. The Front-end can be hosted on Netlify, one of the best platforms for web creation. It's a great solution for small groups making NFT games that don't have the ability to build an infrastructure for their plans by themselves.

Wallet and payments

Let us remember that ordinary money is handled differently than cryptocurrencies. A cryptocurrency is stored in a virtual wallet based on blockchain technology. The crypto portfolio is a space that allows you to store your crypto or NFT without third party intervention. Let us remember that when creating NFT games, we need to guarantee a high level of security for wallets. The best way to choose the appropriate method of storing capital is to go to the web page of the cryptocurrency that interests us, and then check the recommended wallets for storing it.

Each wallet must meet the following requirements:

  • needs to have private and public keys;
  • needs to have several levels of security.

If these conditions are met cumulatively, then everything is done properly.

Smart contracts

Thanks to blockchain technology smart contracts, we have access to programs that run based on fulfilling certain contract terms. Users who want to access the NFT as part of a computer game must follow this procedure:

  1. The Frontend receives the user address from the crypto portfolio.
  2. The Frontend sends the user address to the smart contract.
  3. The smart contract provides the user with a NFT address.

The creation of smart contracts begins by checking the official Ethereum blockchain library, Web3. This allows us to abstract from the internal mechanics of Ethereum and work with networks and intelligent contracts as if they were normal JavaScript objects.

Testing an NFT game

To test an NFT game, it's a good idea to use a particular blockchain for that purpose. For example, Rinkeby. There are several ways to test NFT games, which are as follows:

  • Functionality testing – this is a test to check the overall performance of the game, data transfer, block size etc.
  • Security testing – this is a mandatory test that helps us determine if the blockchain system is in danger of being hacked.
  • Interface testing – when creating an NFT game, keep in mind that you need to make sure that the workflow and functionality work properly.
  • Integration testing – this is the bridge between different programming components.
  • API testing – This checks the software components' communication with the external API, so we can be sure that requests and responses are processed automatically in the proper way.

Summary

Seeing the above requirements you should be aware that creating an NFT game requires a lot of knowledge and dedication. You can create it in various forms. Make sure not to make the gameplay entirely based on monetization. In addition, consider whether the NFT are attractive enough (and the game itself as well) to incentivize players to invest in NFT for the so-called “skins” or other elements of a virtual character. Whether you choose a browser, mobile or hybrid model, it's important to keep in mind that NFT can generate high revenue, but it can also leave a negative impression on players if it is purely finance-focused.

Behavioral Economics in Token Design

Behavioral Economics in Token Design

Behavioral economics is a field that explores the effects of psychological factors on economic decision-making. This branch of study is especially pertinent while designing a token since user perception can significantly impact a token's adoption.

We will delve into how token design choices, such as staking yields, token inflation, and lock-up periods, influence consumer behavior. Research studies reveal that the most significant factor for a token's attractiveness isn’t its functionality, but its past price performance. This underscores the impact of speculative factors. Tokens that have shown previous price increases are preferred over those with more beneficial economic features.

Understanding Behavioral Tokenomics

Understanding User Motivations

The design of a cryptocurrency token can significantly influence user behavior by leveraging common cognitive biases and decision-making processes. For instance, the concept of "scarcity" can create a perceived value increase, prompting users to buy or hold a token in anticipation of future gains. Similarly, "loss aversion," a foundational principle of behavioral economics, suggests that the pain of losing is psychologically more impactful than the pleasure of an equivalent gain. In token design, mechanisms that minimize perceived losses (e.g. anti-dumping measures) can encourage long-term holding.

Incentives and Rewards

Behavioral economics also provides insight into how incentives can be structured to maximize user participation. Cryptocurrencies often use tokens as a form of reward for various behaviors, including mining, staking, or participating in governance through voting. The way these rewards are framed and distributed can greatly affect their effectiveness. For example, offering tokens as rewards for achieving certain milestones can tap into the 'endowment effect,' where people ascribe more value to things simply because they own them.

Social Proof and Network Effects

Social proof, where individuals copy the behavior of others, plays a crucial role in the adoption of tokens. Tokens that are seen being used and promoted by influential figures within the community can quickly gain traction, as new users emulate successful investors. The network effect further amplifies this, where the value of a token increases as more people start using it. This can be seen in the rapid growth of tokens like Ethereum, where the broad adoption of its smart contract functionality created a snowball effect, attracting even more developers and users.

Token Utility and Behavioral Levers

The utility of a token—what it can be used for—is also crucial. Tokens designed to offer real-world applications beyond mere financial speculation can provide more stable value retention. Integrating behavioral economics into utility design involves creating tokens that not only serve practical purposes but also resonate on an emotional level with users, encouraging engagement and investment. For example, tokens that offer governance rights might appeal to users' desire for control and influence within a platform, encouraging them to hold rather than sell.

Understanding Behavioral Tokenomics

Intersection of Behavioral Economics and Tokenomics

Behavioral economics examines how psychological influences, various biases, and the way in which information is framed affect individual decisions. In tokenomics, these factors can significantly impact the success or failure of a cryptocurrency by influencing user behavior towards investment

Influence of Psychological Factors on Token Attraction

A recent study observed that the attractiveness of a token often hinges more on its historical price performance than on intrinsic benefits like yield returns or innovative economic models. This emphasizes the fact that the cryptocurrency sector is still young, and therefore subject to speculative behaviors

The Effect of Presentation and Context

Another interesting finding from the study is the impact of how tokens are presented. In scenarios where tokens are evaluated separately, the influence of their economic attributes on consumer decisions is minimal. However, when tokens are assessed side by side, these attributes become significantly more persuasive. This highlights the importance of context in economic decision-making—a core principle of behavioral economics. It’s easy to translate this into real-life example - just think about the concept of staking yields. When told that the yield on e.g. Cardano is 5% you might not think much of it. But, if you were simultaneously told that Anchor’s yield is 19%, then that 5% seems like a tragic deal.

Implications for Token Designers

The application of behavioral economics to the design of cryptocurrency tokens involves leveraging human psychology to encourage desired behaviors. Here are several core principles of behavioral economics and how they can be effectively utilized in token design:

Leveraging Price Performance

Studies show clearly: “price going up” tends to attract users more than most other token attributes. This finding implies that token designers need to focus on strategies that can showcase their economic effects in the form of price increases. This means that e.g. it would be more beneficial to conduct a buy-back program than to conduct an airdrop.

Scarcity and Perceived Value

Scarcity triggers a sense of urgency and increases perceived value. Cryptocurrency tokens can be designed to have a limited supply, mimicking the scarcity of resources like gold. This not only boosts the perceived rarity and value of the tokens but also drives demand due to the "fear of missing out" (FOMO). By setting a cap on the total number of tokens, developers can create a natural scarcity that may encourage early adoption and long-term holding.

Initial Supply Considerations

The initial supply represents the number of tokens that are available in circulation immediately following the token's launch. The chosen number can influence early market perceptions. For instance, a large initial supply might suggest a lower value per token, which could attract speculators. Data shows that tokens with low nominal value are highly volatile and generally underperform. Understanding how the initial supply can influence investor behavior is important for ensuring the token's stability.

Managing Maximum Supply and Inflation

A finite maximum supply can safeguard the token against inflation, potentially enhancing its value by ensuring scarcity. On the other hand, the inflation rate, which defines the pace at which new tokens are introduced, influences the token's value and user trust.

Investors in cryptocurrency markets show a notable aversion to deflationary tokenomics. Participants are less likely to invest in tokens with a deflationary framework, viewing them as riskier and potentially less profitable. Research suggests that while moderate inflation can be perceived neutrally or even positively, high inflation does not enhance attractiveness, and deflation is distinctly unfavorable.

Source: Behavioral Tokenomics: Consumer Perceptions of Cryptocurrency Token Design

These findings suggest that token designers should avoid high deflation rates, which could deter investment and user engagement. Instead, a balanced approach to inflation, avoiding extremes, appears to be preferred among cryptocurrency investors.

Loss Aversion

People tend to prefer avoiding losses to acquiring equivalent gains; this is known as loss aversion. In token design, this can be leveraged by introducing mechanisms that protect against losses, such as staking rewards that offer consistent returns or features that minimize price volatility. Additionally, creating tokens that users can "earn" through participation or contribution to the network can tap into this principle by making users feel they are safeguarding an investment or adding protective layers to their holdings.

Social Proof

Social proof is a powerful motivator in user adoption and engagement. When potential users see others adopting a token, especially influential figures or peers, they are more likely to perceive it as valuable and trustworthy. Integrating social proof into token marketing strategies, such as showcasing high-profile endorsements or community support, can significantly enhance user acquisition and retention.

Mental Accounting

Mental accounting involves how people categorize and treat money differently depending on its source or intended use. Tokens can be designed to encourage specific spending behaviors by being categorized for certain types of transactions—like tokens that are specifically for governance, others for staking, and others still for transaction fees. By distinguishing tokens in this way, users can more easily rationalize holding or spending them based on their designated purposes.

Endowment Effect

The endowment effect occurs when people value something more highly simply because they own it. For tokenomics, creating opportunities for users to feel ownership can increase attachment and perceived value. This can be done through mechanisms that reward users with tokens for participation or contribution, thus making them more reluctant to part with their holdings because they value them more highly.

Conclusion

By considering how behavioral factors influence market perception, token engineers can create much more effective ecosystems. Ensuring high demand for the token, means ensuring proper funding for the project in general.

FAQ

How does the initial supply of a token influence its market perception?

  • The initial supply sets the perceived value of a token; a larger supply might suggest a lower per-token value.

Why is the maximum supply important in token design?

  • A finite maximum supply signals scarcity, helping protect against inflation and enhance long-term value.

How do investors perceive inflation and deflation in cryptocurrencies?

  • Investors generally dislike deflationary tokens and view them as risky. Moderate inflation is seen neutrally or positively, while high inflation is not favored.

Applying Game Theory in Token Design

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.
