4 most popular blockchains -analysis and comparison of Ethereum, Hyperledger Fabric, Corda and Quorum

You have been interested in blockchain for some time now and are wondering if you could use it in your business model? Undoubtedly it is a technology which has recently gained popularity and which usability in the real estate and entertainment has been found pretty quickly. Among the companies present on the AngelList around 3 thousand use Blockchain. On our Nextrope blog we are trying to explain the most effective ways in which it can be used in business. In this article we compared the 4 most popular protocols- Ethereum, Hyperledger Fabric, Corda and Quorum.

Ethereum

Ethereum is a developer platform based on the blockchain technology which was founded in 2015 by Vitalik Buterin. It allows the creation of decentralised applications which use the smart contracts.

Ethereum was the first blockchain which started to use smart contracts- fragments of Solidity code. Those contracts are called out by EVM, which is the core of Ethereum. Those contracts cannot interact with the surroundings and cant be activated without an input, they must be called out externally. If their function is called out by one of the chains, it automatically carries out the rest. The effects can be seen by the entire network. Thanks to that it is possible for Ethereum to create decentralised applications.

Because the code of established contract cannot be influenced, it is only available for read-only. In order to change it a complete overhaul would be required by establishing a new, completely different code of a different address and the initial state of the variables. The contract cannot be stopped after its execution unless it has been written in its code. Any of the operations on the record of the smart contract are openly logged and can be read through many available blockchain explorers. That way it is guaranteed that the coded information, value or function shall be constant. It is sometimes called „law by code”-creating the law with the usage of the source code.

Ethereum guarantees the constancy of the data and consequently its reliability in the processes of blockchain and smart contracts. That way the need of engaging the third party disappears. It brings many advantages as it grants its users the ability to make transactions directly with the clients, quickens the process of entering into the contract and lowers the costs of increasing the reliability of data.

“We live in the era in which there is no trust, which is why we are creating the third parties which we give our trust to. We send them our data, information, wealth or identity because we want to carry out some common interest and create a positive value. Blockchain will have its use the moment we will be able to fully embrace the cheap, trustful method it can give us”

                                           Maciej Jędrzejczyk IBM Blockchain Leader interview with Nextrope 



Dapps also allow us the reduction of the need of administrative control, for example the business entity which establishes the platform, over the entire network. Very often it finds its use in the b2c relationship. We recently had an occasion to present the examples on how OPUS (which is based on Ethereum) can change the entertainment market. 
Thanks to the decentralization, the safety of data is no more dependant on the single server. If it is destroyed in one of the chains, they still will exist in all the other ones. We already talked about the superiority of the decentralization when it came to land registers which, at the moment, are held in a centralised way which makes them vulnerable towards the random events such as the natural catastrophes or fires. The constant nature of the source code also makes the data invulnerable towards the hackers.

Another advantage behind Ethereum is the tokenisation layer. Token is a smart contract which has a standardised form which stands for a unit of value. Companies create it to make it possible for the users to interact with their products and to make the distribution of prizes and benefits easier. Tokens can be used for accounting the property rights, pay checks or to give the bonuses to old-time clients. Their usage is as broad as the company needs it to be.

Ethereum is the only blockchain in this article that has its own cryptocurrency- Ether. In order to send the data, the user must give the pay- gas for saving it. In order to do this  the user must have his own e-wallet key. Smart contract alone will not be enough to carry out the transaction unless its carried out through the e-wallet.

Hyperledger Fabric

As it turns out, it is not optimal for each user to keep a decentralised registry. Having the privacy of data in mind, in 2018 the Linux foundation has founded the Hyperledger Project which is currently supported by IBM, Intel or SAP Ariba which develops a number of solutions, which also includes the most frequently used Hyperledger Fabric.

Thanks to its modularity, it can be used as a private blockchain which means that only the registered users will be capable of accessing the data which is held by it. It is a key factor when it comes to many companies which are keen on the exchange of data about the transactions between the trusted sides.

The difference in practice

For the purpose of explanation of how Hyperledger works lets imagine a regular Jan who has his own blockchain based shop in Warsaw. Recently he found a Chilean producer of avocado- Emilia. They manage to negotiate a special prize, but Emilia wants to keep this a secret, she wants her clients to still pay the full prize for her prized avocados.

This would be impossible if their transaction was registered in the public domain of blockchain. The other clients would be immediately alarmed of this situation. The transaction would not be even carried out because all of the parties would have to agree on the price.

Hyperledger allows us to solve this problem. The application based on it will check the identity of Jan and then it will send the data about the transaction to Emilia. After agreeing to the established terms, she would send the data back to Jan, and so the transaction could be saved on their registry. In such a situation only two sides of transaction must receive the results. When there is more of them, after the terms are accepted, the transaction deal will be sent to the cloud server where they will be able to accept the transaction after reaching consensus. Then the transaction is saved in the registry.

However, just delivering the avocado to Jans shop engages not only him, but also its producer and many other parties. For the fruit to be delivered to Warsaw the engagement of the shipping agent, the custom and  harbour department and the insurance company which will ensure that the transaction will be secured. The majority of those parties do not need the information about the special prize of avocados. Thanks to Hyperledger, such a transaction can be carried out without the need to use all of the information.

Thats why it finds its use everywhere where privacy and flow of information without the need to share it with all the sides of the transaction is needed. Hyperledger Fabric has its use in the number of different industries, including the financial, logistic and even the food one.

Corda

Another solution which extends the topic of private blockchain networks is Corda, founded by the R3 corporation. The goal of its creation was to create a global registry which would allow the economic operators to interact with each other and manage their contracts. In order to make this possible the platforms architecture must be based on the following principles:

  • Only parties which have justified interests should have access to the registries on the platform
  • The contracts are sustained through the system which is made with the usage of the computer code which makes it so that they are used in accordance to law
  • The consensus is reached out by the people who carry out the transactions, not the entire system 


Platforms like Hyperledger and Ethereum are using smart contracts, however in case of Corda the leading language of their encryption is Kotlin, and the smart contract terminology is replaced by just “contract”. Such contracts use both logic and business data with the judicial process which allows for rooting of the contracts in the existing judicial system.

Corda has two types of consensus: validity of the transaction and the uniqueness of the transaction. In order to acquire the first one, the sides must reach the certainty by checking the entire code behind the contract and by delivering all of the required signs. As far as the second one is concerned, they verify if the transaction is a unique consumer of all of the information.

Quorum

The finance world in mind  sees blockchain as both a chance and a risk. The stability and ease of verification of data is conflicted by the model of public transparency which is opposed by some institutions. Quorum is the platform created by JP Morgan. It is an Ethereum which was improved by the layer of privacy which allows the use of blockchain without the need of making your data public to all of the users.

Just like Corda, it’s a private blockchain, which is created only by the users which were verified by the special program. Quorum can differentiate the private and public transactions in the chain and allow them to appear in one blockchain network. Public ones act like transactions based on Ethereum, however,  the private ones are operated by the system called Constellation. It’s a mechanism which doesn’t use the blockchain technology.  It is based on encryption of the messages on the communication mechanism called enclave – which is the record of the previous transactions, authentications and verifications. Thanks to this, Constellation Quorum is able to process several hundred transactions per minute, much faster than Ethereum or Bitcoin.

Thanks to its reliability and privacy it provides, it’s the perfect solution for the financial sector. Even today it has been recognized by the National Bank of Canada, Central Bank of Brazil or the commercial projects like Adhara or Skeps. It can also be seen that many international companies like Starbucks see the potential behind this technology and are eager to experiment with it.


What is the best blockchain for your business?

The key advantage of every one of aforementioned blockchain solutions is the way in which they solve the problem of a distrust. The companies could possibly save money by investing at the decentralised apps which would allow to save time and give an ability to verify the relations between the parties remotely.

The choice of the platform should be dictated by your current needs. Most b2c companies like facebook ebay or amazon use ethereum which they used to create their own cryptotokens. Hyperledger is chosen mostly by b2b companies which seek to improve their relations. And finally, Corda and Quorum are chosen by financial sector and are used by institutions such as the National Bank of Canada.

Monte Carlo Simulations in Tokenomics

As the web3 field grows in complexity, traditional analytical tools often fall short in capturing the dynamics of digital markets. This is where Monte Carlo simulations come into play, offering a mathematical technique to model systems fraught with uncertainty.

Monte Carlo simulations employ random sampling to understand probable outcomes in processes that are too complex for straightforward analytic solutions. By simulating thousands, or even millions, of scenarios, Monte Carlo methods can provide insights into the likelihood of different outcomes, helping stakeholders make informed decisions under conditions of uncertainty.

In this article, we will explore the role of Monte Carlo simulations within the context of tokenomics.  illustrating how they are employed to forecast market dynamics, assess risk, and optimize strategies in the volatile realm of cryptocurrencies. By integrating this powerful tool, businesses and investors can enhance their analytical capabilities, paving the way for more resilient and adaptable economic models in the digital age.

Understanding Monte Carlo Simulations

The Monte Carlo method is an approach to solving problems that involve random sampling to understand probable outcomes. This technique was first developed in the 1940s by scientists working on the atomic bomb during the Manhattan Project. The method was designed to simplify the complex simulations of neutron diffusion, but it has since evolved to address a broad spectrum of problems across various fields including finance, engineering, and research.

Random Sampling and Statistical Experimentation

At the heart of Monte Carlo simulations is the concept of random sampling from a probability distribution to compute results. This method does not seek a singular precise answer but rather a probability distribution of possible outcomes. By performing a large number of trials with random variables, these simulations mimic the real-life fluctuations and uncertainties inherent in complex systems.

Role of Randomness and Probability Distributions in Simulations

Monte Carlo simulations leverage the power of probability distributions to model potential scenarios in processes where exact outcomes cannot be determined due to uncertainty. Each simulation iteration uses randomly generated values that follow a specific statistical distribution to model different outcomes. This method allows analysts to quantify and visualize the probability of different scenarios occurring.

The strength of Monte Carlo simulations lies in the insight they offer into potential risks. They allow modelers to see into the probabilistic "what-if" scenarios that more closely mimic real-world conditions.

Monte Carlo Simulations in Tokenomics

Monte Carlo simulations are instrumental tool for token engineers. They're so useful due to their ability to model emergent behaviors. Here are some key areas where these simulations are applied:

Pricing and Valuation of Tokens

Determining the value of a new token can be challenging due to the volatile nature of cryptocurrency markets. Monte Carlo simulations help by modeling various market scenarios and price fluctuations over time, allowing analysts to estimate a token's potential future value under different conditions.

Assessing Market Dynamics and Investor Behavior

Cryptocurrency markets are influenced by a myriad of factors including regulatory changes, technological advancements, and shifts in investor sentiment. Monte Carlo methods allow researchers to simulate these variables in an integrated environment to see how they might impact token economics, from overall market cap fluctuations to liquidity concerns.

Assesing Possible Risks

By running a large number of simulations it’s possible to stress-test the project in multiple scenarios and identify emergent risks. This is perhaps the most important function of Monte Carlo Process, since these risks can’t be assessed any other way.

Benefits of Using Monte Carlo Simulations

By generating a range of possible outcomes and their probabilities, Monte Carlo simulations help decision-makers in the cryptocurrency space anticipate potential futures and make informed strategic choices. This capability is invaluable for planning token launches, managing supply mechanisms, and designing marketing strategies to optimize market penetration.

Using Monte Carlo simulations, stakeholders in the tokenomics field can not only understand and mitigate risks but also explore the potential impact of different strategic decisions. This predictive power supports more robust economic models and can lead to more stable and successful token launches. 

Implementing Monte Carlo Simulations

Several tools and software packages can facilitate the implementation of Monte Carlo simulations in tokenomics. One of the most notable is cadCAD, a Python library that provides a flexible and powerful environment for simulating complex systems. 

Overview of cadCAD configuration Components

To better understand how Monte Carlo simulations work in practice, let’s take a look at the cadCAD code snippet:

sim_config = {

    'T': range(200),  # number of timesteps

    'N': 3,           # number of Monte Carlo runs

    'M': params       # model parameters

}

Explanation of Simulation Configuration Components

T: Number of Time Steps

  • Definition: The 'T' parameter in CadCAD configurations specifies the number of time steps the simulation should execute. Each time step represents one iteration of the model, during which the system is updated. That update is based on various rules defined by token engineers in other parts of the code. For example: we might assume that one iteration = one day, and define data-based functions that predict token demand on that day.

N: Number of Monte Carlo Runs

  • Definition: The 'N' parameter sets the number of Monte Carlo runs. Each run represents a complete execution of the simulation from start to finish, using potentially different random seeds for each run. This is essential for capturing variability and understanding the distribution of possible outcomes. For example, we can acknowledge that token’s price will be correlated with the broad cryptocurrency market, which acts somewhat unpredictably.

M: Model Parameters

  • Definition: The 'M' key contains the model parameters, which are variables that influence system's behavior but do not change dynamically with each time step. These parameters can be constants or distributions that are used within the policy and update functions to model the external and internal factors affecting the system.

Importance of These Components

Together, these components define the skeleton of your Monte Carlo simulation in CadCAD. The combination of multiple time steps and Monte Carlo runs allows for a comprehensive exploration of the stochastic nature of the modeled system. By varying the number of timesteps (T) and runs (N), you can adjust the depth and breadth of the exploration, respectively. The parameters (M) provide the necessary context and ensure that each simulation is realistic.

Conclusion

Monte Carlo simulations represent a powerful analytical tool in the arsenal of token engineers. By leveraging the principles of statistics, these simulations provide deep insights into the complex dynamics of token-based systems. This method allows for a nuanced understanding of potential future scenarios and helps with making informed decisions.

We encourage all stakeholders in the blockchain and cryptocurrency space to consider implementing Monte Carlo simulations. The insights gained from such analytical techniques can lead to more effective and resilient economic models, paving the way for the sustainable growth and success of digital currencies.

Behavioral Economics in Token Design

Kajetan Olas

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.
